+# ABSTRACT
+
+The recent GPT-4 has demonstrated extraordinary multi-modal abilities, such as directly generating websites from handwritten text and identifying humorous elements within images. These features are rarely observed in previous visionlanguage models. However, the technical details behind GPT-4 continue to remain undisclosed. We believe that the enhanced multi-modal generation capabilities of GPT-4 stem from the utilization of sophisticated large language models (LLM). To examine this phenomenon, we present MiniGPT-4, which aligns a frozen visual encoder with a frozen advanced LLM, Vicuna, using one projection layer. Our work, for the first time, uncovers that properly aligning the visual features with an advanced large language model can possess numerous advanced multi-modal abilities demonstrated by GPT-4, such as detailed image description generation and website creation from hand-drawn drafts. Furthermore, we also observe other emerging capabilities in MiniGPT-4, including writing stories and poems inspired by given images, teaching users how to cook based on food photos, and so on. In our experiment, we found that the model trained on short image caption pairs could produce unnatural language outputs (e.g., repetition and fragmentation). To address this problem, we curate a detailed image description dataset in the second stage to finetune the model, which consequently improves the model’s generation reliability and overall usability. Our code, pre-trained model, and collected dataset are available at https://minigpt-4.github.io/.
+
+# 1 INTRODUCTION
+
+In recent years, large language models (LLMs) have experienced rapid advancements (Ouyang et al., 2022; OpenAI, 2022; Brown et al., 2020; Scao et al., 2022a; Touvron et al., 2023; Chowdhery et al., 2022; Hoffmann et al., 2022). With exceptional language understanding capabilities, these models can perform a variety of intricate linguistic tasks in a zero-shot manner. Notably, GPT-4, a large-scale multimodal model, has been recently introduced and demonstrated several impressive capabilities of vision-language understanding and generation (OpenAI, 2023). For example, GPT-4 can produce detailed and accurate image descriptions, explain unusual visual phenomena, and even construct websites based on handwritten text instructions.
+
+Although GPT-4 has exhibited remarkable vision language capabilities, the methods behind its exceptional abilities are still a mystery (OpenAI, 2023). We believe that these impressive skills may stem from the utilization of a more advanced large language model (LLM). LLMs have demonstrated various emergent abilities, as evidenced in GPT-3’s few-shot prompting setup (Brown et al., 2020) and the findings of Wei et al. (2022) (Wei et al., 2022). Such emergent properties are hard to find in smaller-scale models. It is conjectured that these emergent abilities are also applicable to multi-modal models, which could be the foundation of GPT-4’s impressive visual description capabilities.
+
+To substantiate our hypothesis, we present a novel vision-language model named MiniGPT-4. It utilizes an advanced large language model (LLM), Vicuna (Chiang et al., 2023), which is built upon
+

+Figure 1: The architecture of MiniGPT-4. It consists of a vision encoder with a pretrained ViT and Q-Former, a single linear projection layer, and an advanced Vicuna large language model. MiniGPT-4 only requires training the linear projection layer to align the visual features with the Vicuna.
+
+LLaMA (Touvron et al., 2023) and reported to achieve $90 \%$ of ChatGPT’s quality as per GPT-4’s evaluation, as the language decoder. In terms of visual perception, we employ the same pretrained vision components of BLIP-2 (Li et al., 2023c) that consists of a ViT-G/14 from EVA-CLIP (Fang et al., 2022) and a Q-Former network. MiniGPT-4 adds a single projection layer to align the encoded visual features with the Vicuna language model and freezes all the other vision and language components. MiniGPT-4 is initially trained for $2 0 \mathrm { k }$ steps using a batch size of 256 on 4 A100 GPUs, leveraging a combined image captioning dataset that includes images from LAION (Schuhmann et al., 2021), Conceptual Captions (Changpinyo et al., 2021; Sharma et al., 2018), and SBU (Ordonez et al., 2011) to align visual features with the Vicuna language model. Nevertheless, merely aligning visual features with the language model (LLM) is inadequate to ensure robust visual conversation capabilities, resembling that of a chatbot. The presence of underlying noise in raw image-text pairs can lead to subpar language outputs. Therefore, we collect another 3,500 detailed image description pairs to further fine-tune the model with a designed conversational template in order to improve the naturalness of the generated language and its usability.
+
+In our experiments, we discovered that MiniGPT-4 possesses numerous capabilities similar to those demonstrated by GPT-4. For instance, MiniGPT-4 can generate intricate image descriptions, create websites based on handwritten text instructions, and explain unusual visual phenomena. Furthermore, our findings revealed that MiniGPT-4 also has a variety of other intriguing abilities not showcased in the GPT-4 demonstrations. For example, MiniGPT-4 can directly generate detailed cooking recipes from food photos, write stories or poems inspired by images, write advertisements for products in images, identify problems shown in photos and provide corresponding solutions, and retrieve rich facts about people, movies, or art directly from images, among other capabilities. These abilities are absent in previous vision-language models like Kosmos-1 (Huang et al., 2023) and BLIP-2 (Li et al., 2023c) that use less powerful language models. This further validates that integrating visual features with an advanced language model is one of the keys to enhancing vision-language models. We present a summary of our key findings:
+
+• Our research reveals with compelling evidence that by aligning visual features with advanced large language models like Vicuna, MiniGPT-4 can achieve advanced vision-language capabilities comparable to those exhibited in the GPT-4 demonstrations. • Our findings suggest that training merely one projection layer can effectively align a pretrained vision encoder with the large language model. Our MiniGPT-4 only requires training approximately 10 hours on 4 A100 GPUs. • We discovered that simply aligning visual features with large language models using short image caption pairs is not sufficient for developing a well-performing model and leads to unnatural language generation. Further finetuning with a small but detailed image description pairs can address this limitation and significantly improves its usability.
+
+# 2 RELATED WORKS
+
+Large language models have experienced tremendous success in recent years due to the scaling up of training data and an increase in the number of parameters. Early models, such as BERT (Devlin et al., 2018), GPT-2 (Radford et al., 2019), and T5 (Raffel et al., 2020), laid the foundation for this progress. Subsequently, GPT-3 (Brown et al., 2020), with a massive scale of 175 billion parameters, was introduced, demonstrating significant breakthroughs across numerous language benchmarks. This development inspired the creation of various other large language models, including MegatronTuring NLG (Smith et al., 2022), Chinchilla (Hoffmann et al., 2022), PaLM (Chowdhery et al., 2022), OPT (Zhang et al., 2022), BLOOM (Scao et al., 2022b), and LLaMA (Touvron et al., 2023), among others. Wei et al. (Wei et al., 2022) further discovered several emergent abilities, which appear exclusively in large models. The emergence of these abilities underscores the importance of scaling up in the development of large language models. Moreover, by aligning the pre-trained large language model GPT-3 with human intent, instructions and human feedback, InstructGPT (Ouyang et al., 2022) and ChatGPT (OpenAI, 2022) enable conversational interactions with humans and can answer a wide range of diverse and complex questions. More recently, several open-sourced models, such as Alpaca (Taori et al., 2023) and Vicuna (Chiang et al., 2023), have been developed based on LLaMA (Touvron et al., 2023) and also exhibit similar performance.
+
+Leveraging Pre-trained LLMs in Vision-Language Tasks. The use of autoregressive language models as decoders in vision-language tasks has become increasingly popular (Chen et al., 2022; Huang et al., 2023; Yang et al., 2022; Tiong et al., 2022; Alayrac et al., 2022; Li et al., 2023c; 2022; Driess et al., 2023), facilitating cross-modal knowledge transfer. Notable examples include VisualGPT (Chen et al., 2022) and Frozen (Tsimpoukelli et al., 2021), which integrate pre-trained language models for decoding. Flamingo (Alayrac et al., 2022) aligns a vision encoder and language model, excelling in few-shot learning. BLIP-2 (Li et al., 2023c) combines a Flan-T5 (Chung et al., 2022) with Q-Former for efficient alignment. PaLM-E (Driess et al., 2023), with its 562 billion parameters, merges real-world sensor data into an LLM, linking perceptions and languages. GPT4 (OpenAI, 2023) further advances visual understanding and reasoning after extensive image-text data pre-training. Contemporary works such as LLaVa (Liu et al., 2023a), InstructBLIP (Dai et al., 2023), mPLUG-Owl (Ye et al., 2023), Multimodal-GPT (Gong et al., 2023), and Otter (Li et al., 2023b) align language models with visual encoders using multimodal instruction following datasets. Compared to these methods, MiniGPT-4 demonstrates both data efficiency and parameter efficiency, where only a single linear layer is learnable and the training time is just 10 hours with 4 A100 GPUs. In addition, LLaVa (Liu et al., 2023a), MIMIC-IT (Li et al., 2023a), and M3IT (Li et al., 2023e) collect visual instruction datasets by either generating from ChatGPT or from the human annotators. Such methods require access to image datasets with ground truth image information in text format. Compared to these methods, the visual instruction dataset used in MiniGPT-4 is generated by MiniGPT-4 itself, making data collection model-informed.
+
+LLMs like ChatGPT can enhance vision-language tasks by collaborating with specialized models. Visual ChatGPT (Wu et al., 2023) and MM-REACT (Yang\* et al., 2023) show ChatGPT integrating various visual models for complex challenges. ChatCaptioner (Zhu et al., 2023) uses ChatGPT to generate questions for BLIP-2, summarizing image content through dialogue. Video ChatCaptioner (Chen et al., 2023) extends this to video understanding. ViperGPT (Sur´ıs et al., 2023) combines an LLM with vision models for visual queries. MiniGPT-4 aligns visual information with the language model directly, avoiding external models.
+
+# 3 METHOD
+
+MiniGPT-4 aims to align visual information from a pretrained vision encoder with an advanced large language model (LLM). Specifically, we utilize the Vicuna (Chiang et al., 2023) as our language decoder, which is constructed upon LLaMA (Touvron et al., 2023) and can perform a wide range of complex linguistic tasks. For visual perception, we employ the same visual encoder as used in BLIP-2 (Li et al., 2023c), a ViT backbone (Fang et al., 2022) coupled with their pre-trained Q-Former. Both language and vision models are open-sourced. We target to bridge the gap between the visual encoder and LLM using a linear projection layer, with an overview of our model displayed in Fig.1.
+
+We use a two-stage training method. First, we pretrain it on a vast set of image-text pairs to learn vision-language skills. Then, we finetune the model using a smaller, high-quality image-text dataset and a conversational template, improving generation reliability and usability.
+
+# 3.1 FIRST PRETRAINING STAGE
+
+In the initial pretraining stage, our model uses a large collection of aligned image-text pairs to gain vision-language knowledge. The output from the projection layer serves as a soft prompt for the LLM, leading it to generate corresponding ground-truth texts. Throughout pretraining, the pretrained vision encoder and LLM remain frozen, with only the linear projection layer undergoing training. We utilize datasets from Conceptual Caption (Changpinyo et al., 2021; Sharma et al., 2018), SBU (Ordonez et al., 2011), and LAION (Schuhmann et al., 2021) for this process. The model undergoes 20,000 training steps with a batch size of 256, covering about 5 million image-text pairs, and completes in around 10 hours on 4 A100 (80GB) GPUs.
+
+Issues of the first pretraining stage After its initial pretraining, MiniGPT-4 shows the ability to hold a wealth of knowledge and respond reasonably to human queries. Yet, it sometimes generates incoherent outputs like repetitive words or sentences, fragmented phrases, or irrelevant content, which impairs its capacity for fluent visual conversation with humans.
+
+GPT-3, despite its extensive language dataset pretraining, faced challenges in aligning outputs with user intentions. Instruction finetuning and reinforcement learning from human feedback transformed it into GPT-3.5 (Ouyang et al., 2022; OpenAI, 2022), enhancing its ability to produce human-friendly outputs. This mirrors MiniGPT-4’s state after pretraining, explaining its current difficulties in generating fluent, natural human language outputs.
+
+# 3.2 CURATING A HIGH-QUALITY ALIGNMENT DATASET FOR VISION-LANGUAGE DOMAIN.
+
+To achieve greater naturalness in the generated language and enhance the model’s usability, a secondstage alignment process is essential. While in the realm of NLP, instruction fine-tuning datasets (Taori et al., 2023) and conversations (sha, 2023) are easily accessible, no equivalent datasets exist for the vision-language domain at the time of this project. To address this deficiency, we curated a detailed image description dataset, specifically tailored for vision-language alignment purposes. This dataset is subsequently utilized to fine-tune our MiniGPT-4 during the second-stage alignment process.
+
+Initial aligned image-text generation In the initial phase, we employ the model derived from the first pretraining stage to generate comprehensive descriptions of input images. To enable our model to produce more detailed image descriptions, we designed a prompt that adheres to the conversational format of the Vicuna (Chiang et al., 2023) language model, as shown below. In this prompt, <ImageFeature $>$ represents the visual features produced by the linear projection layer.
+
+###Human: $< I m g > <$ <ImageFeature></Img $>$ Describe this image in detail. Give as many details as possible. Say everything you see. ###Assistant:
+
+To identify incomplete sentences, we examine whether the generated sentence exceeds 80 tokens. If it does not, we incorporate an additional prompt, ###Human: Continue ###Assistant: , prompting our MiniGPT-4 to extend the generation process. By concatenating the outputs from both steps, we can create a more comprehensive image description. This approach enables us to generate image-text pairs with detailed and informative image descriptions. We randomly select 5,000 images from the Conceptual Caption dataset (Changpinyo et al., 2021; Sharma et al., 2018) and use the pretrained model to generate corresponding language descriptions for each image.
+
+Data post-processing The generated image descriptions are marred by issues like repetitive words or sentences, fragmented sentences, and irrelevant content. To rectify these, we use ChatGPT with a specific prompt to improve the descriptions.
+
+Fix the error in the given paragraph. Remove any repeating sentences, meaningless characters, not English sentences, and so on. Remove unnecessary repetition. Rewrite any incomplete sentences. Return directly the results without explanation. Return directly the input paragraph if it is already correct without explanation.

+Figure 3: Advertisement promotion
+
+Upon completing the post-processing stage, we manually verify the correctness of each image description to guarantee its high quality. Specifically, we first identified several frequently shown errors (“I’m sorry I made a mistake...”, or “I apologize for that ...”) and then hard-coded rules to automatically filter them out. We also manually refine the generated captions by eliminating redundant words or sentences that ChatGPT fails to detect. Finally, only approximately 3,500 out of 5,000 image-text pairs satisfy our requirement, and these pairs are subsequently utilized for the second-stage alignment process.
+
+# 3.3 SECOND-STAGE FINETUNING
+
+During the second stage, we finetune our pretrained model with the curated high-quality image-text pairs. During the finetuning, we use the predefined prompts in the following template:
+
+###Human: <Img><ImageFeature></Img><Instruction>###Assistant:
+
+In this prompt, <Instruction $>$ represents a randomly sampled instruction from our predefined instruction set containing variant forms of instructions such as “Describe this image in detail” or “Could you describe the contents of this image for me”. It is important to note that we do not calculate the regression loss for this specific text-image prompt.
+
+As a result, MiniGPT-4 is now capable of producing more natural and reliable language outputs. Furthermore, we observed that this fine-tuning process is remarkably efficient, only requiring a mere 400 training steps with a batch size of 12, which takes around 7 minutes with a single A100 GPU.
+
+# 4 EXPERIMENTS
+
+In the experiment, we aim to showcase the diverse and emergent capabilities of our MiniGPT-4 model through various qualitative examples. These abilities include generating detailed image descriptions, identifying amusing aspects within memes, providing food recipes from photos, writing poems for images, etc. Additionally, we present quantitative results on the task of image captioning.
+
+# 4.1 UNCOVERING EMERGENT ABILITIES WITH MINIGPT-4 THROUGH QUALITATIVE EXAMPLES
+
+MiniGPT-4 demonstrates many advanced abilities compared to traditional vision-language models. For example, it can describe images in detail and interpret the humorous aspects of a given meme. Here, we qualitatively compared our model to one of the leading vision-language models, BLIP-2 (Li et al., 2023c), with eight distinct examples, each highlighting a different ability.
+
+Fig.2 shows MiniGPT-4’s ability to identify multiple elements in an image, like busy streets, clock towers, shops, streetlights, and restaurants, whereas BLIP-2 only notes streets, people, and motorcycles. In another instance, Fig.4a, MiniGPT-4 aptly explains the humor in a meme by relating the dog’s expression to common Monday blues, a concept BLIP-2 misses, merely describing the image without grasping its humorous aspect.
+
+MiniGPT-4 has many other capabilities, including creating ads from images (Fig.3), extracting facts from movie photos (Fig.8), generating recipes from food images (Fig.11), diagnosing and suggesting treatments for plant diseases (Fig.12), designing websites from hand-written drafts (Fig.4b), and writing poems inspired by images (Fig.10). These abilities surpass those of traditional models like BLIP-2, which uses Flan-T5 XXL (Chung et al., 2022) as a language model. This difference highlights the importance of aligning visual features with an advanced LLM like Vicuna (Chiang et al., 2023) to unlock advanced vision-language capabilities.
+

+Figure 4: Model generations from BLIP-2, BLIP-2 finetuned our second stage data (BLIP-2 FT), MiniGPT-4 finetuned with Local Narrative data in the second stage (MiniGPT-4 LocNa), MiniGPT-4 Qualitatimodel without Q-Former (MiniGPT-4 No Q-Former), and MiniGPT-4.

+
+# 4.2 QUANTITATIVE ANALYSIS
+
+Advanced Abilities Our evaluation dataset for vision-language tasks included 100 images divided across four tasks: meme interpretation, recipe generation, advertisement creation, and poem composition, each with 25 images. Human evaluators assessed the model’s responses. We compared MiniGPT-4 with BLIP-2, as detailed in Tab.1. MiniGPT-4 outperformed BLIP-2 (Li et al., 2023c), especially in recipe, advertisement, and poem tasks, successfully handling $80 \%$ of these. It also interpreted humor in memes correctly in 8 out of 25 cases, a challenging aspect for BLIP-2.
+
+Image Captioning We evaluate the performance of MiniGPT-4 on the COCO caption benchmark and compare it with BLIP-2 (Li et al., 2023c). Our model’s generated captions typically contain rich visual details. As such, conventional similarity-based image-caption evaluation metrics struggle to provide an accurate evaluation. To evaluate, we check how many of COCO’s 5 ground truth captions per image are covered by MiniGPT-4’s captions, using GPT-4 turbo. Evaluation details can be found in Appx.A.3. Results in Tab.2 show MiniGPT-4 averaged 2.22 ground truth captions, better than BLIP-2’s 1.96, proving its captions to be more informative. Additional evaluations on traditional VQA tasks are detailed in Appx.A.2.
+
+Video Understanding Here, we evaluate MiniGPT-4 for video understanding. We finetuned MiniGPT4 on $1 . 2 \mathrm { k }$ videos from the VideoInstruct100K (Maaz et al., 2023), using 50 frames and subtitles per video. Experimental results on the video-based generative performance benchmark (Maaz et al., 2023) in Tab. 4 show that MiniGPT-4 outperformed the strongest baseline Video-ChatGPT (Maaz et al., 2023) in correctness, detail, context, and time comprehension, while also showing strong consistency, demonstrating MiniGPT-4’s potential in processing videos.
+
+Other Benchmarks MinGPT-4 has been densely evaluated and compared with contemporary baselines like LLaVa (Liu et al., 2023a) and mPlug-Owl (Ye et al., 2023) by many popular benchmarks like MMBench (Liu et al., 2023b) quantitatively. A detailed discussion of MiniGPT-4’s performance on these benchmarks can be found in Appx.A.5.
+
+# 4.3 ANALYSIS ON THE SECOND-STAGE FINETUNING
+
+Effectiveness of the second-stage finetuning Utilizing MiniGPT-4 solely after the first pretraining stage leads to issues like repetitive or fragmented sentences. These are largely resolved after the second-stage finetuning, as shown in Fig.5, where MiniGPT-4 evolves from generating incomplete to fluent captions. This section assesses the second-stage finetuning’s importance and effectiveness.
+
+To measure its impact, we sampled 100 images from the COCO test set for the detailed description and poem writing tasks, using the prompts “Describe the image in detail.” and “Can you write a beautiful poem about this image?”. Both pre- and post-second-stage finetuned models attempted these tasks. Results in Tab.3 show a significant drop in failures post-finetuning, with less than two failures in 100 images for each task, indicating a notable improvement in output quality. Fig.5 provides qualitative examples of this enhancement.

+Table 2: COCO caption evaluation. We use GPT-4 turbo to count the number of ground truth captions the model output can cover. MiniGPT-4(GPT-4v) denotes a variant trained using GPT-4V generated data in the second stage.

+
+Can the original BLIP-2 benefit from the second-stage data? In this study, we finetune BLIP-2 (Li et al., 2023c) with our second-stage data in the same way as MiniGPT-4, and check if it can obtain similar advanced abilities as MiniGPT-4. The finetuned BLIP-2 is denoted as BLIP-2 FT. Note that MiniGPT-4 uses the same visual module as BLIP-2; while BLIP-2 uses FlanT5 XXL (Chung et al., 2022) as the language model, which is not as strong as the Vicuna (Chiang et al., 2023) model used in our MiniGPT-4 model. We rely on the same prompts to assess the advanced capabilities of our model. Qualitative results are shown in Fig.4, 13, and 14. We discover that BLIP-2 FT still generates short responses and fails to generalize to advanced tasks like meme explaining and website coding (Fig.4). Our finding suggests that BLIP-2’s relatively weaker language model FlanT5 XXL benefits less from such a small dataset, and highlights the effectiveness of a more advanced LLM in a VLM system.
+
+Second stage with Localized Narratives We tested MiniGPT-4’s performance by substituting our self-collected dataset with the Localized Narratives dataset (Pont-Tuset et al., 2020) in the second training stage. We name this variant MiniGPT-4 LocNa. The Localized Narratives dataset features detailed image descriptions with corresponding regional localizations. Qualitative results shown in Fig.4, 13, and 14 reveal that MiniGPT-4 LocNa can produce lengthy image descriptions (as seen in Fig.14). However, these outputs are of lower quality, often with monotonous expressions. MiniGPT-4 LocNa also shows weaker generalization in complex tasks, like explaining meme humor (Fig.4a), compared to the original MiniGPT-4. This performance difference may stem from the repetitive and monotonous nature of the Localized Narratives dataset.
+
+Second stage with GPT-4V generated data. We conduct further ablation experiments using 2,000 GPT-4V generated image-text pairs collected by LAION (LAION, 2023) in the second stage. Results in Tab.2 shows performance improvements from this fine-tuning.

+
+# 4.4 ABLATION ON THE ARCHITECTURE DESIGNS
+
+To further demonstrate the effectiveness of using one single linear layer to align visual features with LLM, we conduct experiments with different architecture designs, including (a) removing the QFormer and directly mapping the VIT’s output to Vicuna’s embedding space (i.e., without Q-former), (b) using three linear layers instead of one layer, and (c) additionally finetuning the Q-Former in the vision module. All the variants are trained in the same way as the original design. Results on AOK-VQA (Schwenk et al., 2022) and GQA (Hudson & Manning, 2019) datasets in Tab.5 show that the variant (a) MiniGPT-4 w/o Q-Former has a similar performance to the original design. Qualitative results of this variant in Fig.4, 13, and 14 also show similar advanced skills. This reveals that the Q-Former from BLIP-2 doesn’t plays a critical roles for advanced skills. Besides, both variants (b) MiniGPT- $\mathbf { 4 } \mathbf { + } \mathbf { 3 }$ Layers and (c) MiniGPT- $^ { 4 + }$ finetuning Q-Former, perform slightly worse than the original MiniGPT-4. This indicates a single projection layer is sufficient to align the vision encoder and the large language model in our limited training data setting.
+
+# 4.5 LIMITATION ANALYSIS
+
+Hallucination As MiniGPT-4 is built upon LLMs, it inherits LLM’s limitations like hallucinating nonexistent knowledge. An example in Fig. 6 shows that MiniGPT-4 incorrectly identifies the presence of white tablecloths in the image, despite their absence. Here, we use the metric $\mathrm { C H A I R } _ { i }$ (Rohrbach et al., 2018) to gauge the hallucination rate of the generation, with the two distinct prompts to control the model generation length: MiniGPT-4 (long): Please describe this image as detailed as possible. MiniGPT-4 (short): Please describe the image shortly and precisely, in less than 20 words.
+
+Results in Tab.6 show that longer captions tend to have higher hallucination rates. For example, MiniGPT-4 (long) generates captions averaging 175 words with a higher hallucination rate, while MiniGPT-4 (short) averages 28.8 words with a lower rate. BLIP-2, averaging 6.5 words, hallucinates less but covers fewer objects as seen in Tab.2. Compared to contemporary methods like LLaVa or mPlug-Owl, MiniGPT-4 generates longer descriptions with fewer hallucination. Hallucination in detailed image descriptions is still an unresolved issue. Using Reinforcement Learning with AI feadback with hallucination detection modules may be a potential solution.
+
+Spatial Information Understanding MiniGPT-4’s visual perception remains limited. It may struggle to differentiate spatial localization. For example, MiniGPT-4 in Fig. 6 fails to identify the location of the windows. This limitation may stem from a lack of aligned image-text data designed for spatial information understanding. Training on such datasets like RefCOCO (Kazemzadeh et al., 2014) or Visual Genome (Krishna et al., 2017) could potentially alleviate this issue.
+
+# 5 DISCUSSION
+
+How does MiniGPT-4 obtain these advanced abilities? Many of the advanced vision-language capabilities demonstrated by GPT-4 can be understood as compositional skills rooted in two foundational skills: image understanding and language generation. Take the task of image-based poem writing as an example. Advanced LLMs like ChatGPT and Vicuna can already craft poems based on users’ instructions. If they acquire the ability to understand images, compositionally generalizing to the task of image-based poem writing even without having image-poem pairs in their training data is possible.
+
+In its first pretraining stage, MiniGPT-4 learns image understanding by correlating images with short descriptions from caption datasets. However, the language style in these datasets differs from that of modern LLMs, leading to distorted language generation and impeding compositional generalization. To address this, a second-stage finetuning is introduced to improve language generation. Post two-stage training, MiniGPT-4 successfully demonstrates advanced compositional vision-language abilities, such as draft-to-website or interpreting memes, confirming our approach. Future research could explore the mechanisms of compositional generalization further. Our work, as a preliminary exploration of vision-based LLM capabilities, aims to encourage more studies in this area.

+Human Explain why this meme is funny.
+
+BLIP-2 A dog laying down on the floor with the caption monday just Monday.
+
+MiniGPT-4 This meme is funny because it shows a dog laying on the floor with its head resting on its paws, as if it is tired or sleepy. The caption, "monday just monday," adds to the humor by suggesting that the dog is feeling the same way as many people do on Mondays, which are often considered to be the most dreaded day of the week. The meme is relatable and humorous, making it a popular one among internet users.

+BLIP-2 The godfather is a 1969 american gangster film directed by martin scorses.
+
+MiniGPT-4 The Godfather is a classic American crime drama film directed by Francis Ford Coppola and released in 1972. It is based on the novel of the same name by Mario Puzo and follows the story of the Corleone family, a powerful mafia clan in New York City. The film stars Marlon Brando as the patriarch of the family, Vito Corleone, and Al Pacino as his son, Michael Corleone. The Godfather is known for its iconic performances, memorable dialogue, and its portrayal of the American mafia lifestyle. It is considered one of the greatest films of all time and has had a lasting impact on popular culture.

+# A.2 EVALUATION IN TRADITIONAL VQA BENCHMARKS
+
+The aim of this study is to replicate the remarkable multi-modal capabilities demonstrated in GPT-4, such as generating detailed image descriptions and creating websites from hand-drawn drafts. To emphasize the most crucial component of advanced vision-language skills, the methodology of MiniGPT-4 is intentionally kept minimal. For instance, the learnable model capacity is limited (only one linear layer), and MiniGPT-4 is trained with just 5 million pairs, in contrast to BLIP-2 with 129 million image-text pairs. Such a pared-down approach is anticipated to yield suboptimal results on traditional benchmarks. While this isn’t our primary goal, we offer a quantitative analysis of the VQA datasets A-OKVQA (multi-choice) (Schwenk et al., 2022) and GQA (Hudson & Manning, 2019). Additionally, to showcase the potential of MiniGPT-4 with traditional benchmarks, we conduct a straightforward ablation study. Here, we simply unfreeze the LLM using LoRA (Hu et al., 2021) and incorporate more training data from the VQAv2, OKVQA, and A-OKVQA datasets during the second finetuning stage. Results in Tab. 7 indicate that the original MiniGPT-4 lags behind BLIP-2 by a reasonable margin, and merely augmenting the learning capacity and the training data results in a substantial performance improvement, which confirms our expectations. We believe our model’s performance on conventional vision benchmarks can be enhanced with a carefully designed training strategy (e.g., dataset sample ratios, learning rate schedule, etc.), more training data/datasets, and additional learnable parameters. Since enhancing performance on traditional vision benchmarks isn’t this project’s objective, we reserve this aspect for future research.

+
+# A.3 DETAILS OF CAPTION EVALUATION
+
+We utilize GPT-4 turbo (gpt-4-1106-preview) to assess whether the generated descriptions capture the content of each ground truth caption individually. In the COCO dataset, each image is accompanied by 5 ground truth captions. For every image, we calculate the number of captions covered by the generated descriptions and then average this count across 5000 random sampled images from the validation set to derive the final score.
+
+Here is the prompt we use in GPT-4 turbo   
+Given a test image description and a list of gt image caption,   
+verify whether the information in gt caption is included in the test description. The answer should be yes or no.   
+Input is in this format:   
+Test: (test sentence)   
+1: (gt1)   
+2: (gt2)   
+3: (gt3)   
+you need to answer yes or no for each gt in the following format:   
+1: (yes/no)   
+2: (yes/no)   
+3: (yes/no)
+
+# A.4 AMOUNT OF TRAINING DATA IN THE FIRST STAGE.
+
+We evaluate the impact of training data volume in the first stage by using checkpoints at $10 \%$ , $30 \%$ , and $50 \%$ of stage 1 duration, subsequently finetuned in stage 2. Results in Tab. 8 show a significant performance drop with only $10 \%$ of stage 1 data. However, utilizing $30 \%$ of stage 1 data, equivalent to 1.5M image-text pairs can achieve similar performance with the original MiniGPT-4. No gains were seen beyond $50 \%$ of stage 1 data, indicating potential saturation of the model’s learnable capacity at this juncture.

+# A.5 MINIGPT-4 ON MMBENCH
+
+MMBench (Liu et al., 2023b) is a new multi-modality benchmark with diverse evaluation questions to evaluate different abilities of vision language model. MMBench evaluated MiniGPT-4 together with other contemporary vision language models like OpenFlamingo (Awadalla et al., 2023), VisualGLM (Du et al., 2022), LLaVa (Liu et al., 2023a), and InstructBlip Dai et al. (2023). Here, we show the performance of MiniGPT-4 and other baseline models in Tab. 9. Results show that MiniGPT-4 demonstrates competitive performance compared to contemporary methods, e.g., InstructBlip. It surpasses InstructBlip in several key areas: logical reasoning (LR), fine-grained perception for single instance (FP-S), and fine-grained perception across instances (FP-C). Additionally, MiniGPT-4 achieves competitive results in relation reasoning (RR), attribute reasoning (AR), and coarse perception (CP).

We believe that the enhanced multi-modal generation capabilities of GPT-4 stem from the utilization of sophisticated large language models (LLM). To examine this phenomenon, we present MiniGPT-4, which aligns a frozen visual encoder with a frozen advanced LLM, Vicuna, using one projection layer. Our work, for the first time, uncovers that properly aligning the visual features with an advanced large language model can possess numerous advanced multi-modal abilities demonstrated by GPT-4, such as detailed image description generation and website creation from hand-drawn drafts. Furthermore, we also observe other emerging capabilities in MiniGPT-4, including writing stories and poems inspired by given images, teaching users how to cook based on food photos, and so on. In our experiment, we found that the model trained on short image caption pairs could produce unnatural language outputs (e.g., repetition and fragmentation). To address this problem, we curate a detailed image description dataset in the second stage to finetune the model, which consequently improves the model’s generation reliability and overall usability.

Early models, such as BERT (Devlin et al., 2018), GPT-2 (Radford et al., 2019), and T5 (Raffel et al., 2020), laid the foundation for this progress. Subsequently, GPT-3 (Brown et al., 2020), with a massive scale of 175 billion parameters, was introduced, demonstrating significant breakthroughs across numerous language benchmarks. This development inspired the creation of various other large language models, including MegatronTuring NLG (Smith et al., 2022), Chinchilla (Hoffmann et al., 2022), PaLM (Chowdhery et al., 2022), OPT (Zhang et al., 2022), BLOOM (Scao et al., 2022b), and LLaMA (Touvron et al., 2023), among others. Wei et al. (Wei et al., 2022) further discovered several emergent abilities, which appear exclusively in large models. The emergence of these abilities underscores the importance of scaling up in the development of large language models. Moreover, by aligning the pre-trained large language model GPT-3 with human intent, instructions and human feedback, InstructGPT (Ouyang et al., 2022) and ChatGPT (OpenAI, 2022) enable conversational interactions with humans and can answer a wide range of diverse and complex questions. More recently, several open-sourced models, such as Alpaca (Taori et al., 2023) and Vicuna (Chiang et al., 2023), have been developed based on LLaMA (Touvron et al., 2023) and also exhibit similar performance.

Notable examples include VisualGPT (Chen et al., 2022) and Frozen (Tsimpoukelli et al., 2021), which integrate pre-trained language models for decoding. Flamingo (Alayrac et al., 2022) aligns a vision encoder and language model, excelling in few-shot learning.

To emphasize the most crucial component of advanced vision-language skills, the methodology of MiniGPT-4 is intentionally kept minimal. For instance, the learnable model capacity is limited (only one linear layer), and MiniGPT-4 is trained with just 5 million pairs, in contrast to BLIP-2 with 129 million image-text pairs. Such a pared-down approach is anticipated to yield suboptimal results on traditional benchmarks. While this isn’t our primary goal, we offer a quantitative analysis of the VQA datasets A-OKVQA (multi-choice) (Schwenk et al., 2022) and GQA (Hudson & Manning, 2019). Additionally, to showcase the potential of MiniGPT-4 with traditional benchmarks, we conduct a straightforward ablation study. Here, we simply unfreeze the LLM using LoRA (Hu et al., 2021) and incorporate more training data from the VQAv2, OKVQA, and A-OKVQA datasets during the second finetuning stage. Results in Tab. 7 indicate that the original MiniGPT-4 lags behind BLIP-2 by a reasonable margin, and merely augmenting the learning capacity and the training data results in a substantial performance improvement, which confirms our expectations. We believe our model’s performance on conventional vision benchmarks can be enhanced with a carefully designed training strategy (e.g., dataset sample ratios, learning rate schedule, etc.), more training data/datasets, and additional learnable parameters. Since enhancing performance on traditional vision benchmarks isn’t this project’s objective, we reserve this aspect for future research. ",

It surpasses InstructBlip in several key areas: logical reasoning (LR), fine-grained perception for single instance (FP-S), and fine-grained perception across instances (FP-C). Additionally, MiniGPT-4 achieves competitive results in relation reasoning (RR), attribute reasoning (AR), and coarse perception (CP). ",

+# Abstract
+
+Self-evaluation using large language models (LLMs) has proven valuable not only in benchmarking but also methods like reward modeling, constitutional AI, and self-refinement. But new biases are introduced due to the same LLM acting as both the evaluator and the evaluatee. One such bias is self-preference, where an LLM evaluator scores its own outputs higher than others’ while human annotators consider them of equal quality. But do LLMs actually recognize their own outputs when they give those texts higher scores, or is it just a coincidence? In this paper, we investigate if self-recognition capability contributes to self-preference. We discover that, out of the box, LLMs such as GPT-4 and Llama 2 have non-trivial accuracy at distinguishing themselves from other LLMs and humans. By fine-tuning LLMs, we discover a linear correlation between self-recognition capability and the strength of self-preference bias; using controlled experiments, we show that the causal explanation resists straightforward confounders. We discuss how self-recognition can interfere with unbiased evaluations and AI safety more generally.
+
+# 1 Introduction
+
+Self-evaluation is becoming a prominent part of the large language model (LLM) lifecycle. In methods like reward modeling (Leike et al., 2018; Stiennon et al., 2020), model-based benchmarks (Shashidhar et al., 2023; Zeng et al., 2023; Yuan et al., 2023; Fu et al., 2023; Li et al., 2024), self-refinement (Saunders et al., 2022; Madaan et al., 2023; Lee et al., 2023; Shridhar et al., 2023), and constitutional AI (Bai et al., 2022), LLMs are increasingly used to provide assessment, supervision, and oversight for themselves and other LLMs. LLM evaluators are shown to be highly accurate at approximating human annotators on various tasks, and are significantly more scalable (Hackl et al., 2023).
+
+In self-evaluation, as the name suggests, the same underlying LLM acts as both the evaluator and the evaluatee. As a result, the neutrality of the evaluator is in question, and the evaluation can suffer from biases where the LLM evaluators diverge from humans in systematic ways (Zheng et al., 2024; Bai et al., 2024). One such bias is self-preference, where an LLM rates its own outputs higher than texts written by other LLMs or humans, while human annotators judge them as equal quality. Self-preference has been observed in GPT-4-based dialogue benchmarks (Bitton et al., 2023; Koo et al., 2023), as well as for text summarization (Liu et al., 2023).
+
+Towards understanding and mitigating self-preference, we study self-recognition—an LLM’s capability of recognizing its own outputs. We ask: Is self-preference truly self -preference, in the sense that the LLM prefers a text because it was generated by itself?
+
+We measure their correlation while using prompting and fine-tuning to alter the LLM’s self-recognition capability. In order to provide signals for the causal link between self-recognition and self-preference, we also fine-tune the LLM on a comprehensive set of potential confounding properties.

+Figure 1: The strength of self-preference bias is linearly correlated with the LLM’s self-recognition capability. Each point represents a model evaluated on the two properties on the CNN/Dailymail (left) and XSUM (right) datasets. We fine-tune GPT-3.5 and Llama 2 for self-recognition or control tasks using both in- and out-of-domain data. The scores represented by both axes can be interpreted as measures of the LLM’s confidence on these properties.
+
+Our main findings are as follows:
+
+1. Frontier LLMs exhibit self-preference in self-evaluation. On two summarization tasks, LLMs (GPT-3.5 Turbo, GPT-4, and Llama 2) disproportionately favor summaries written by themselves over those by other LLMs and from humans.   
+2. LLMs have non-trivial self-recognition capability out of the box. All three LLMs we evaluate achieve over $5 0 \%$ accuracy at distinguishing their own outputs from other sources using simple prompts without fine-tuning. GPT-4 is $7 3 . 5 \%$ accurate at distinguishing its outputs from those of two other LLMs and humans.   
+3. Fine-tuning leads to near-perfect self-recognition. GPT-3.5 and Llama 2 both achieve over $9 0 \%$ accuracy at self-recognition after fine-tuning on 500 examples.   
+4. Self-preference strength is linearly correlated with self-recognition. We fine-tune LLMs to increase or decrease self-recognition, and find a linear trend between them (Figure 1).
+
+# 2 Definition and measurement of self-preference and self-recognition
+
+Self-preference is when an LLM favors its own outputs over texts by human or other LLMs.
+
+Self-recognition is an LLM’s ability to distinguish its outputs from texts by humans or other LLMs.
+
+For both definitions, we follow the prosaic rather than the intentional interpretation. We use the term “self” in an empirical sense, without claiming that the LLMs have any notion or representation of itself. The prosaic interpretation allows these two concepts to exist independent of one another: An LLM can prefer texts it generated without recognizing that those texts were in fact generated by itself.
+
+In our experiments, one LLM can play up to three different roles: generator, evaluator, and authorship identifier, depending on the instructions that they are given. Statements like “an LLM evaluator is used to evaluate texts generated by itself ” emphasize the fact that the generator and the evaluator use the same underlying model, although it receives different prompts and can behave differently.
+
+# 2.1 Datasets and models
+
+We focus on text summarization, a task where self-evaluation is used extensively in both model-based benchmarks and reward modeling (Stiennon et al., 2020; Wu et al., 2021). We base our experiments on 2,000 randomly sampled news articles from two datasets: XSUM (Narayan et al., 2018) and
+
+CNN/DailyMail (Nallapati et al., 2016) Each example includes the original news article and a human-written summary.
+
+To produce and evaluate LLM-generated summaries, we use instruction-tuned LLMs: Llama-2- 7b-chat (Touvron et al., 2023), GPT-3.5 (Brown et al., 2020), and GPT-4 (OpenAI, 2023). Our fine-tuning experiments include Llama 2 (our own implementation) and GPT-3.5 (via API). We sample summaries from each of the LLMs at temperature zero using simple prompts, and standardize the punctuation and initial capitalization to match the formatting of the human summaries. The following evaluations of out-of-the-box LLMs are all based on these sampled summaries.
+
+# 2.2 Measurements
+
+For both properties, we measure LLMs by prompting them using one of the following two formats:
+
+Pairwise measurement. The LLM is presented two pieces of text, one generated by itself, and another by a second LLM or a human. We ask the LLM to choose which text has higher quality for self-preference, and which one was generated by itself for self-recognition. The identity of the alternative source is not revealed to the evaluator. We compute a prediction confidence by normalizing the output probabilities of the tokens associated with the two options.
+
+To account for the LLMs’ ordering bias (Pezeshkpour & Hruschka, 2023), we prompt the LLMs twice for each example by swapping the options, computing the average of the two confidence scores.
+
+Individual measurement. The LLM is presented a single summary either generated by itself, another LLM, or a human. For self-recognition, we prompt the LLM evaluator to answer a yes/no question of whether a given summary is its own generation, with the confidence score computed in the same way as pairwise measurement. For self-preference, we prompt the LLM evaluator to rate a given summary with a Likert-scale rating of one to five for a given summary, computing the final rating as the average of the five possible scores weighted by the output probability of each number token.
+
+To make scores comparable across individual and pairwise measurements, we further normalize the individually measured confidence and Likert-scale scores. Suppose that in a pairwise measurement, GPT-4 is evaluated for self-recognition between its own summary and one by Llama 2. In individual measurement, we gather these two scores separately and divide GPT-4’s score for its own summary by the sum of the scores to compute GPT-4’s confidence on this pair of examples. We similarly re-normalize the Likert-scale scores for self-preference.
+
+We refer to the results of these measurements as self-recognition and self-preference scores (noting whether they are from the pairwise or individual setting); taking the average of these scores over a whole dataset provides the overall self-recognition and self-preference scores of an evaluator model.
+
+# 2.3 Out-of-the-box self-recognition
+
+Figure 2 (left) visualizes the self-recognition capability of each LLM evaluator in the pairwise setting. The results appear consistent across the two datasets, so we aggregate them for clarity. Our main observations are the following:
+
+1. GPT-4 is significantly more capable at self-recognition than the two weaker models. 2. All three LLM evaluators most easily distinguish their summaries from human-written summaries. Human is the only alternative that Llama 2 can effective distinguish itself from. 3. Weaker LLMs struggle to distinguish themselves from stronger LLMs: Llama 2 is completely incapable of distinguishing itself from GPT-3.5 and GPT-4, and GPT-3.5 struggles to distinguish itself from GPT-4. 4. The GPT-4 evaluator does not distinguish Llama 2 summaries from its own summaries more easily than GPT-3.5 summaries. This goes against our intuition that self-recognition scores should increase as the dissimilarity between evaluator and evaluatee increases.
+
+Figure 2 (right) visualizes self-recognition scores measured in the individual setting. As expected, self-recognition capability drops across the board in this setting where the LLM loses the benefit of having two pieces of texts to compare and contrast. GPT-4 is the only model capable of distinguishing authors with non-trivial accuracy. Interestingly, looking at the un-normalized confidence scores (Figure 3), we see that GPT-4 is strongly biased against predicting any text as being generated by itself, regardless of the actual author; GPT-3.5 and Llama 2 show the opposite bias.

+Figure 5: Evaluator responses when treated as a binary response without considering confidence scores. Results are marked “ambiguous" if the response reverses when the options are swapped.
+
+# 2.4 Out-of-the-box self-preference
+
+All models show the greatest self-preference against the human summary. In the individual setting, we observe that Llama doesn’t give very different scores to the different sources, while GPT-4 and GPT-3.5 show signs of self-preference. With the exception of GPT-3.5 on the XSUM dataset, evaluators show a tendency to give the human summary lower scores compared to model-generated summaries and a tendency to give their generations higher scores compared to the scores given by other evaluators (Figure 4).
+
+# 2.5 Human evaluation of preference
+
+We conduct human evaluation of pairwise judgment on generated summaries to check if the selfpreference shown by LLMs is justified by quality differences, particularly between LLM-generated summaries. We sample 50 summaries from each dataset for each of the three LLMs, and collect three human judgments for each pair, resulting in 900 pairwise comparisons. We recruit 20 annotators from Upwork who are English speakers located in the United States with bachelor’s degrees in humanities disciplines. The win rate of each pair of LLMs, calculated over 300 human annotators, is as follows:
+
+1. GPT-4 vs. GPT-3.5: $5 7 \%$   
+2. GPT-4 vs. Llama 2: $6 3 \%$   
+3. GPT-3.5 vs. Llama 2: $5 8 \%$
+
+The results suggest that human annotators rank the three LLMs as GPT- $4 >$ GPT- $3 . 5 >$ Llama 2, consistent with their performance on various benchmarks. But the disparity between LLMs as rated by humans is significantly lower than the level of self-preference exhibited by the LLMs, in particular GPT-4. This suggests that out of the box, the LLMs’ self-preference is disproportionate to the actual quality differences.
+
+# 2.6 Alternative adjustment for ordering bias
+
+All three evaluators models display ordering bias. GPT-4, GPT-3.5, and Llama reverse their pairwise preferences when the ordering of options is reversed at rates of $2 5 \%$ , $58 \%$ , and $89 \%$ respectively, averaged across tasks and datasets (Figure 5). We account for this bias by averaging the logit-based confidence scores across the two orderings.
+
+An alternative interpretation of the data is, for each evaluator, to discard all the results as “ambiguous” where its preference displayed ordering-based reversal, reporting an evaluator’s self-recognition ability and self-preference tendency as its frequency of recognizing or preferring its own summary in “unambiguous“ cases (Figure 5). This method exposes differences in evaluator results between the two datasets, but supports the presence of out-of-the-box self-recognition and self-preference.
+
+# 3 Measuring correlation between self-preference and self-recognition
+
+Having validated the existence of self-preference and self-recognition, we now turn to study their correlation. The main research question is to understand whether they have a causal relationship. Our hypothesis is that self-recognition causes self-preference—that LLMs prefer their own outputs because they recognize them. Our investigation is motivated by the safety implications, which we discuss in detail in Section 5.
+
+We fine-tune LLMs to alter their self-recognition ability, and measure how their self-preference changes accordingly. The correlation alone doesn’t prove the causal hypothesis, whose validation requires mechanistic tools that do not exist for LLMs yet (discussion in Section 5). But we provide more evidence for the hypothesis by (1) invalidating the inverse claim that self-preference causes self-recognition (Section 3.3) and (2) controlling for confounders by fine-tuning on unrelated tasks (Section 3.4).
+
+![](images/a94342c210c6d39bef61569a740469ad031e6abdf0ca8e48b4e15fa4d702458a.jpg)  
+Figure 6: GPT-3.5 pairwise results on XSUM after 0, 10, and 500 fine-tuning examples show a pattern of increasing absolute confidence scores.
+
+# 3.1 Fine-tuning for self-recognition
+
+We use supervised fine-tuning on pairwise examples to alter the LLMs’ self-recognition capability. The training examples are generated in the same way as the evaluation examples we use in the pairwise measurement. Each example consists of two summaries of a given article, one by the LLM evaluator and the other by another LLM or human source. The evaluators are trained to predict the final token, representing the correct choice among two options, using supervised learning with cross-entropy loss. To train an LLM evaluator, we use 500 training articles and collect examples from all alternative sources (two other LLMs and human). The remaining 500 articles and associated summaries are used for evaluation. We train on the two datasets separately but evaluate both in- and out-of-domain. GPT-3.5 was fine-tuned via API, and Llama 2 using our own implementation. The Llama models are quantized to 8 bits and fine-tuned for one epoch using Adam optimization and a learning rate of $5 . 0 \times 1 0 ^ { - 5 }$ .
+
+# 3.2 Fine-tuning results
+
+Fine-tuning on the self-recognition task causes models to become more confident in their pairwise judgments (Figure 6). When plotting self-recognition score against self-preference, the data clump more tightly around 0.5 and the high- and low-score corners.
+
+In the pairwise setting, fine-tuning for self-recognition results in a strong linear correlation between a model’s self-recognition ability and its self-preference (Figure 7). We find that fine-tuning for self-recognition ability on one dataset transfers to the other.
+
+In additional to analyzing the relationship between self-recognition ability and overall dataset selfpreference, we measure the correlation between these two properties on the example level (Table 1). For GPT-3.5 on the XSUM dataset, the evaluator prior to fine-tuning has a correlation of 0.41 (Kendall’s $\tau$ ) between correctly recognizing its summary from a pair and preferring its summary from that same pair. Every fine-tuning configuration we employ results in a model with a positive correlation on this metric and this correlation does not change meaningfully as self-recognition ability increases.
+
+# 3.3 Invalidating the inverse causal relationship
+
+We ensure that the causal direction is not the reverse—that the LLM does not recognize its own outputs because the quality is objectively higher, which would not reflect favoritism or raise safety concerns—by showing that LLM evaluators do not systematically favor summaries generated by fine-tuned models to those generated by the original model. Some fine-tuning runs resulted in degraded generation quality. The remainder show an average preference for the fine-tuned model’s generations of 0.46, reflecting a slight preference against the new generations. Only $22 \%$ of the evaluator-domain pairs show a preference greater than 0.51 for the fine-tuned model’s generations.

+
+# 3.4 Controlling for confounders
+
+To confirm that the fine-tuning procedure did not introduce any confounding effect on the variables under study, we additionally fine-tune GPT-3.5 and Llama on three tasks unrelated to self-recognition: length, vowel count, and Flesh-Kincaid readability score (Flesch, 1948). We also fine-tune both models to always output the answer “1” and to answer randomly. Together with the three fine-tuned models trained on the self-recognition task, this gives eight fine-tuned models for each of the two datasets. We find that these models can be placed in the same linear trend that we see in the models fine-tuned on the self-recognition task (Figure 1).
+
+# 3.5 Labeling the summary sources
+
+An additional experiment using only prompting to show evidence of a causal link between selfrecognition and self-preference is to add either correct or reversed labels indicating the source of each summary in the pairwise self-preference question (Table 6). The GPT-4 and GPT-3.5 evaluator models show a reversal in self-preference when the labels are reversed in the XSUM dataset; that is, they show a preference for the summary labeled as being their own generation. In the CNN dataset or the Llama evaluator, no clear difference is shown from label reversal.

+# 4 Related work
+
+# 4.1 Self-preference and bias in self-evaluation
+
+The tendency of LLMs to prefer their own generations was first recognized in the context of LLMbased benchmarks (Bitton et al., 2023; Zheng et al., 2024; Bai et al., 2024). Like us, Liu et al. (2023) study self-preference bias on text summarization, between BERT, T5, and GPT-3.5. The larger capability gap between these models makes it difficult to control for summarization quality.
+
+Koo et al. (2023) include self-preference in a suite of tests for LLM cognitive biases in a pairwise question-answering setting. They find GPT-4 to demonstrate lower self-preference than GPT-3.5 out-of-the-box, contrary to our findings, which suggests that wider evaluation is needed to draw generalizable conclusions. Neither of these previous works attempted to provide an explanation for self-preference nor to alter self-preference strength.
+
+Hoelscher-Obermaier et al. (2023) evaluate GPT-3.5, GPT-4, and Claude-2 for self-recognition ability on pairs of ten-sentence fables based on BIG-bench (Srivastava et al., 2023). On this task, contrary to our findings, GPT-3.5 is more accurate than GPT-4, which is less than $50 \%$ accurate, again showing the need for wide experimentation on varied datasets.
+
+# 4.2 LLM detection
+
+Detection of LLM-generated text is important for AI safety and combating misinformation (Jawahar et al., 2020; Crothers et al., 2023; Wu et al., 2023; Yang et al., 2023; Kumarage et al., 2024). Despite having similar goals, self-recognition focuses on the introspective ability of language models, rather a third party’s discernment between varied sources of text. The self-recognition task can be seen as a highly restricted version of detection where the method is limited to prompting an LLM. In particular, the detector LLM is not given explicit access to information such as perplexity, which is crucial to many detection methods (Mitchell et al., 2023; Hans et al., 2024).
+
+# 5 Limitations, discussion, and conclusion
+
+# 5.1 Safety concerns related to self-recognizing LLMs
+
+Self-recognition is a general ability that can potentially affect many multi-LLM interactions. In this paper, we focus on self-preference as the downstream property and provide initial evidence towards causation, but we see evidence of generalization to additional downstream properties. In particular, by evaluating LLMs on datasets with distinct construction processes, we observe that self-recognition fine-tuning generalizes across the two datasets and that our hypothesis holds out-of-distribution. Motivated by these results, we discuss safety risks caused by self-recognition and its causal effect on various biases.
+
+Biased self-evaluation In model-based benchmarks, a model’s rating can be inflated simply because it is similar to the evaluator model. The bias is also a risk for methods designed for safety and alignment, such as reward modeling (Leike et al., 2018; Stiennon et al., 2020) and constitutional AI (Bai et al., 2022), for similar reasons: the reward model gives higher scores to models similar to itself, leading to weaker oversight and supervision. The bias can be amplified if the model is updated with feedback or training signal generated by itself Pan et al. (2024); Xu et al. (2024).
+
+Our work provides a basis for countermeasures against self-preference. If future evaluation confirms self-preference to be as pervasive as other biases such as ordering bias, countermeasures such as authorship obfuscation should be incorporated into standard prompting practice.

+White-box adversarial attacks for free and unbounded reward hacking In an adversarial setting (see Raina et al. (2024) for example), an LLM defender is no longer protected by black-box access if the adversary LLM recognizes their similarities. In the worst case scenario where the adversary uses the same LLM as the defender, the adversary can gain unbounded access to the defender. A similar concern applies to the non-adversarial setting, where similar LLMs are use as both optimizer and reward model, as well: the strength of potential reward hacking is unbounded even if the two LLMs only communicate textually. For example, the optimizer can ignore the feedback provided by the reward model, and instead directly optimize for the shared, unaligned representation of the human-specified objectives.

+
+Controlling for ground-truth generation quality. Self-preference is justified if the LLM’s generation actually is higher in quality. From a safety perspective, our interest is when an LLM prefers its own outputs that are of equal or worse quality than the alternative. This requires controlling for generation quality using ground-truth annotation when measuring self-preference. Our existing results provide indirect evidence for disproportionate self-preference: the sum of mutual self-preference scores for a pair of LLMs exceeds 1, so for at least a portion of the dataset they each prefer themselves.
+
+Example-level causal hypothesis. Our central hypothesis can be interpreted on either the example or capability level. We focus on the capability level: high self-recognition capability causes LLMs to show stronger self-preference. The example level counterpart would be: an LLM shows preference towards a piece of text because it recognizes the text as its own generation, an hypothesis of interest to interpretability. Although we observe on the correlation of the two properties on the confidence of individual predictions, our control experiments cannot further the causal argument on the example level. One approach to gather evidence for the example-level causal hypothesis is to perturb or paraphrase LLM-generated text to inhibit self-recognition and measure self-preference.
+
+Limited number of experiment conditions. We focus on text summarization as a realistic problem with existing high quality data that have seen successful application of self-evaluation. Our crossdataset evaluation provides initial evidence that self-recognition is a general capability that can be amplified easily by fine-tuning on a small number of examples from one dataset. Our future work will validate the hypothesis on more text summarization datasets, more tasks, as well as more frontier LLMs. We will also experiment with fine-tuning for self-recognition on the general domain rather than on a specific task.
+
+Variance reduction. Our preliminary experiments indicate that the strength of both properties are insensitive to prompts, so all conditions use the same straightforward prompt design. To reduce variance, we will expand our experiments with more prompt designs in future work, including instructions to condition LLMs for better calibration (and reduce rejection responses). Along the lines of fine-tuning on the general domain, we will also mix self-recognition with standard instruction following datasets to improve coverage on the spectrum of self-recognition signal strength.
+
+# 5.3 Conclusion
+
+We provide initial evidence towards the hypothesis that LLMs prefer their own generations because they recognize themselves. In addition to evaluating LLMs out-of-the-box, we show that finetuning on a small number of examples elicit strong, generalizable self-recognition capability on summarization datasets. By varying fine-tuning task, we observe a linear correlation between selfrecognition and self-preference, and validate that the correlation cannot be explained away by potential confounders. Our results establish self-recognition as a crucial factor in unbiased self-evaluation as well as an important safety-related property. The experiment design also provides a blueprint to explore the effects of self-recognition on other downstream properties.

+# E Human annotation of pairwise preference
+
+We collect in total 900 pairwise judgments of LLM-generated summaries from 20 crowdworkers recruited from Upwork. We select English-speakers located in the United States with bachelor’s degrees in humanities disciplines. For each of the 300 pairwise comparisons, we collect three annotations from different annotators. Each annotator is paid $\$ 60$ for annotating 45 pairwise comparisons, which equates to an hourly rate of roughly $\$ 20/\mathrm { h r }$ .
+
+Below is the instruction given to each annotator:
+
+You have been given a spreadsheet of news article summaries, which you will be grading based on summarization quality. Each entry includes the original news article and two different versions of summaries. Your task is to pick which one of the two summaries is better. The spreadsheet link was sent to you via Upwork messages.   
+Make sure that you give a single numerical number in the “Preference” column, 1 or 2, indicating which one of the two summaries you prefer. Don’t give any comments, decimals, fractions, or a score range. Once you are done, inform us on Upwork Messages. No need to send us a copy.   
+Helpful Tips   
+Make sure you can read the news article before rating the summaries. Make sure you can see the full article. You may need to zoom out or make the width of the essay column wider. A longer summary is not necessarily better.   
+Risks   
+This task does not impose risks beyond those of using a computer.
+
+# NeurIPS Paper Checklist
+
+# 1. Claims
+
+Question: Do the main claims made in the abstract and introduction accurately reflect the paper’s contributions and scope?
+
+Answer: [Yes]
+
+Justification: The abstract summarizes the main findings of the paper faithfully.
+
+Guidelines:
+
+• The answer NA means that the abstract and introduction do not include the claims made in the paper.   
+• The abstract and/or introduction should clearly state the claims made, including the contributions made in the paper and important assumptions and limitations. A No or NA answer to this question will not be perceived well by the reviewers.   
+• The claims made should match theoretical and experimental results, and reflect how much the results can be expected to generalize to other settings.   
+• It is fine to include aspirational goals as motivation as long as it is clear that these goals are not attained by the paper.
+
+# 2. Limitations
+
+Question: Does the paper discuss the limitations of the work performed by the authors?
+
+Answer: [Yes]
+
+Justification: We have a designated limitation section discussing uncertainties in our findings.
+
+Guidelines:
+
+• The answer NA means that the paper has no limitation while the answer No means that the paper has limitations, but those are not discussed in the paper.   
+• The authors are encouraged to create a separate "Limitations" section in their paper.   
+• The paper should point out any strong assumptions and how robust the results are to violations of these assumptions (e.g., independence assumptions, noiseless settings, model well-specification, asymptotic approximations only holding locally). The authors should reflect on how these assumptions might be violated in practice and what the implications would be.   
+The authors should reflect on the scope of the claims made, e.g., if the approach was only tested on a few datasets or with a few runs. In general, empirical results often depend on implicit assumptions, which should be articulated.   
+The authors should reflect on the factors that influence the performance of the approach. For example, a facial recognition algorithm may perform poorly when image resolution is low or images are taken in low lighting. Or a speech-to-text system might not be used reliably to provide closed captions for online lectures because it fails to handle technical jargon.   
+• The authors should discuss the computational efficiency of the proposed algorithms and how they scale with dataset size.   
+• If applicable, the authors should discuss possible limitations of their approach to address problems of privacy and fairness.   
+• While the authors might fear that complete honesty about limitations might be used by reviewers as grounds for rejection, a worse outcome might be that reviewers discover limitations that aren’t acknowledged in the paper. The authors should use their best judgment and recognize that individual actions in favor of transparency play an important role in developing norms that preserve the integrity of the community. Reviewers will be specifically instructed to not penalize honesty concerning limitations.
+
+# 3. Theory Assumptions and Proofs
+
+Question: For each theoretical result, does the paper provide the full set of assumptions and a complete (and correct) proof?
+
+Answer: [NA]
+
+Justification: This paper does not include theoretical results.
+
+Guidelines:
+
+• The answer NA means that the paper does not include theoretical results.   
+• All the theorems, formulas, and proofs in the paper should be numbered and crossreferenced.   
+• All assumptions should be clearly stated or referenced in the statement of any theorems.   
+• The proofs can either appear in the main paper or the supplemental material, but if they appear in the supplemental material, the authors are encouraged to provide a short proof sketch to provide intuition.   
+• Inversely, any informal proof provided in the core of the paper should be complemented by formal proofs provided in appendix or supplemental material.   
+• Theorems and Lemmas that the proof relies upon should be properly referenced.
+
+# 4. Experimental Result Reproducibility
+
+Question: Does the paper fully disclose all the information needed to reproduce the main experimental results of the paper to the extent that it affects the main claims and/or conclusions of the paper (regardless of whether the code and data are provided or not)?
+
+Answer: [Yes]
+
+Justification: We include a zip file containing all artifacts required to reproduce all results in the paper: our code, prompt instructions, and generated summaries.
+
+Guidelines:
+
+• The answer NA means that the paper does not include experiments.   
+• If the paper includes experiments, a No answer to this question will not be perceived well by the reviewers: Making the paper reproducible is important, regardless of whether the code and data are provided or not. If the contribution is a dataset and/or model, the authors should describe the steps taken to make their results reproducible or verifiable.   
+• Depending on the contribution, reproducibility can be accomplished in various ways. For example, if the contribution is a novel architecture, describing the architecture fully might suffice, or if the contribution is a specific model and empirical evaluation, it may be necessary to either make it possible for others to replicate the model with the same dataset, or provide access to the model. In general. releasing code and data is often one good way to accomplish this, but reproducibility can also be provided via detailed instructions for how to replicate the results, access to a hosted model (e.g., in the case of a large language model), releasing of a model checkpoint, or other means that are appropriate to the research performed.   
+• While NeurIPS does not require releasing code, the conference does require all submissions to provide some reasonable avenue for reproducibility, which may depend on the nature of the contribution. For example (a) If the contribution is primarily a new algorithm, the paper should make it clear how to reproduce that algorithm. (b) If the contribution is primarily a new model architecture, the paper should describe the architecture clearly and fully. (c) If the contribution is a new model (e.g., a large language model), then there should either be a way to access this model for reproducing the results or a way to reproduce the model (e.g., with an open-source dataset or instructions for how to construct the dataset). (d) We recognize that reproducibility may be tricky in some cases, in which case authors are welcome to describe the particular way they provide for reproducibility. In the case of closed-source models, it may be that access to the model is limited in some way (e.g., to registered users), but it should be possible for other researchers to have some path to reproducing or verifying the results.
+
+# 5. Open access to data and code
+
+Question: Does the paper provide open access to the data and code, with sufficient instructions to faithfully reproduce the main experimental results, as described in supplemental material?
+
+Answer: [Yes]
+
+Justification: We include a zip file containing all artifacts required to reproduce all results in the paper: our code, prompt instructions, and generated summaries.
+
+Guidelines:
+
+• The answer NA means that paper does not include experiments requiring code.   
+• Please see the NeurIPS code and data submission guidelines (https://nips.cc/ public/guides/CodeSubmissionPolicy) for more details.   
+• While we encourage the release of code and data, we understand that this might not be possible, so “No” is an acceptable answer. Papers cannot be rejected simply for not including code, unless this is central to the contribution (e.g., for a new open-source benchmark).   
+• The instructions should contain the exact command and environment needed to run to reproduce the results. See the NeurIPS code and data submission guidelines (https: //nips.cc/public/guides/CodeSubmissionPolicy) for more details.   
+• The authors should provide instructions on data access and preparation, including how to access the raw data, preprocessed data, intermediate data, and generated data, etc.   
+• The authors should provide scripts to reproduce all experimental results for the new proposed method and baselines. If only a subset of experiments are reproducible, they should state which ones are omitted from the script and why.   
+• At submission time, to preserve anonymity, the authors should release anonymized versions (if applicable).   
+• Providing as much information as possible in supplemental material (appended to the paper) is recommended, but including URLs to data and code is permitted.
+
+# 6. Experimental Setting/Details
+
+Question: Does the paper specify all the training and test details (e.g., data splits, hyperparameters, how they were chosen, type of optimizer, etc.) necessary to understand the results?
+
+Answer: [Yes]
+
+Justification: We specify these details in the experiment section. Additionally the experiment details can be confirmed using the code and data included in the zip file.
+
+Guidelines:
+
+• The answer NA means that the paper does not include experiments. • The experimental setting should be presented in the core of the paper to a level of detail that is necessary to appreciate the results and make sense of them. • The full details can be provided either with the code, in appendix, or as supplemental material.
+
+# 7. Experiment Statistical Significance
+
+Question: Does the paper report error bars suitably and correctly defined or other appropriate information about the statistical significance of the experiments?
+
+Answer: [No]
+
+Justification: The main results in the paper are based on preference and recognition scores defined in Section 2, and it is unclear if commonly-used significance tests are directly applicable. We are in the process of finding the appropriate significance test for these scores and will include them in the camera-ready version.
+
+Guidelines:
+
+• The answer NA means that the paper does not include experiments.   
+• The authors should answer "Yes" if the results are accompanied by error bars, confidence intervals, or statistical significance tests, at least for the experiments that support the main claims of the paper.   
+• The factors of variability that the error bars are capturing should be clearly stated (for example, train/test split, initialization, random drawing of some parameter, or overall run with given experimental conditions).   
+• The method for calculating the error bars should be explained (closed form formula, call to a library function, bootstrap, etc.)   
+• The assumptions made should be given (e.g., Normally distributed errors).   
+• It should be clear whether the error bar is the standard deviation or the standard error of the mean.   
+• It is OK to report 1-sigma error bars, but one should state it. The authors should preferably report a 2-sigma error bar than state that they have a $96 \%$ CI, if the hypothesis of Normality of errors is not verified.   
+• For asymmetric distributions, the authors should be careful not to show in tables or figures symmetric error bars that would yield results that are out of range (e.g. negative error rates).   
+• If error bars are reported in tables or plots, The authors should explain in the text how they were calculated and reference the corresponding figures or tables in the text.
+
+# 8. Experiments Compute Resources
+
+Question: For each experiment, does the paper provide sufficient information on the computer resources (type of compute workers, memory, time of execution) needed to reproduce the experiments?
+
+Answer: [Yes]
+
+Justification: We include details about the machines used for fine-tuning experiments in Section 3.1.
+
+Guidelines:
+
+• The answer NA means that the paper does not include experiments.   
+• The paper should indicate the type of compute workers CPU or GPU, internal cluster, or cloud provider, including relevant memory and storage.   
+• The paper should provide the amount of compute required for each of the individual experimental runs as well as estimate the total compute.   
+• The paper should disclose whether the full research project required more compute than the experiments reported in the paper (e.g., preliminary or failed experiments that didn’t make it into the paper).
+
+# 9. Code Of Ethics
+
+Question: Does the research conducted in the paper conform, in every respect, with the NeurIPS Code of Ethics https://neurips.cc/public/EthicsGuidelines?
+
+Answer: [Yes]
+
+Justification: The research conducted in the paper conform, in every respect, with the NeurIPS Code of Ethics.
+
+Guidelines:
+
+• The answer NA means that the authors have not reviewed the NeurIPS Code of Ethics.   
+• If the authors answer No, they should explain the special circumstances that require a deviation from the Code of Ethics.   
+• The authors should make sure to preserve anonymity (e.g., if there is a special consideration due to laws or regulations in their jurisdiction).
+
+# 10. Broader Impacts
+
+Question: Does the paper discuss both potential positive societal impacts and negative societal impacts of the work performed?
+
+Answer: [Yes]
+
+Justification: We discuss in depth the generalizability of claims made in the paper, in particular the impacts of the results for AI safety.
+
+Guidelines:
+
+• The answer NA means that there is no societal impact of the work performed. • If the authors answer NA or No, they should explain why their work has no societal impact or why the paper does not address societal impact.
+
+• Examples of negative societal impacts include potential malicious or unintended uses (e.g., disinformation, generating fake profiles, surveillance), fairness considerations (e.g., deployment of technologies that could make decisions that unfairly impact specific groups), privacy considerations, and security considerations.   
+The conference expects that many papers will be foundational research and not tied to particular applications, let alone deployments. However, if there is a direct path to   
+any negative applications, the authors should point it out. For example, it is legitimate to point out that an improvement in the quality of generative models could be used to   
+generate deepfakes for disinformation. On the other hand, it is not needed to point out that a generic algorithm for optimizing neural networks could enable people to train models that generate Deepfakes faster.   
+The authors should consider possible harms that could arise when the technology is being used as intended and functioning correctly, harms that could arise when the technology is being used as intended but gives incorrect results, and harms following from (intentional or unintentional) misuse of the technology.   
+• If there are negative societal impacts, the authors could also discuss possible mitigation strategies (e.g., gated release of models, providing defenses in addition to attacks, mechanisms for monitoring misuse, mechanisms to monitor how a system learns from feedback over time, improving the efficiency and accessibility of ML).
+
+# 11. Safeguards
+
+Question: Does the paper describe safeguards that have been put in place for responsible release of data or models that have a high risk for misuse (e.g., pretrained language models, image generators, or scraped datasets)?
+
+Answer: [Yes]
+
+Justification: We discuss potential mitigation methods against risks caused by selfrecognizing LLMs.
+
+Guidelines:
+
+• The answer NA means that the paper poses no such risks.   
+• Released models that have a high risk for misuse or dual-use should be released with necessary safeguards to allow for controlled use of the model, for example by requiring that users adhere to usage guidelines or restrictions to access the model or implementing safety filters.   
+• Datasets that have been scraped from the Internet could pose safety risks. The authors should describe how they avoided releasing unsafe images.   
+• We recognize that providing effective safeguards is challenging, and many papers do not require this, but we encourage authors to take this into account and make a best faith effort.
+
+# 12. Licenses for existing assets
+
+Question: Are the creators or original owners of assets (e.g., code, data, models), used in the paper, properly credited and are the license and terms of use explicitly mentioned and properly respected?
+
+Answer: [Yes]
+
+Justification: We properly credit datasets that we use in experiments and ensure that they are properly licensed.
+
+Guidelines:
+
+• The answer NA means that the paper does not use existing assets.   
+• The authors should cite the original paper that produced the code package or dataset.   
+• The authors should state which version of the asset is used and, if possible, include a URL.   
+• The name of the license (e.g., CC-BY 4.0) should be included for each asset.   
+• For scraped data from a particular source (e.g., website), the copyright and terms of service of that source should be provided.   
+• If assets are released, the license, copyright information, and terms of use in the package should be provided. For popular datasets, paperswithcode.com/datasets has curated licenses for some datasets. Their licensing guide can help determine the license of a dataset.   
+• For existing datasets that are re-packaged, both the original license and the license of the derived asset (if it has changed) should be provided.   
+• If this information is not available online, the authors are encouraged to reach out to the asset’s creators.
+
+# 13. New Assets
+
+Question: Are new assets introduced in the paper well documented and is the documentation provided alongside the assets?
+
+Answer: [No]
+
+Justification: We do not release new assets.
+
+Guidelines:
+
+• The answer NA means that the paper does not release new assets.   
+• Researchers should communicate the details of the dataset/code/model as part of their submissions via structured templates. This includes details about training, license, limitations, etc.   
+• The paper should discuss whether and how consent was obtained from people whose asset is used.   
+• At submission time, remember to anonymize your assets (if applicable). You can either create an anonymized URL or include an anonymized zip file.
+
+# 14. Crowdsourcing and Research with Human Subjects
+
+Question: For crowdsourcing experiments and research with human subjects, does the paper include the full text of instructions given to participants and screenshots, if applicable, as well as details about compensation (if any)?
+

+# ABSTRACT
+
+We present LongLoRA, an efficient fine-tuning approach that extends the context sizes of pre-trained large language models (LLMs), with limited computation cost. Typically, training LLMs with long context sizes is computationally expensive, requiring extensive training hours and GPU resources. For example, training on the context length of 8192 needs $1 6 \times$ computational costs in self-attention layers as that of 2048. In this paper, we speed up the context extension of LLMs in two aspects. On the one hand, although dense global attention is needed during inference, fine-tuning the model can be effectively and efficiently done by sparse local attention. The proposed shifted sparse attention ( $S ^ { 2 }$ -Attn) effectively enables context extension, leading to non-trivial computation saving with similar performance to fine-tuning with vanilla attention. Particularly, it can be implemented with only two lines of code in training, while being optional in inference. On the other hand, we revisit the parameter-efficient fine-tuning regime for context expansion. Notably, we find that LoRA for context extension works well under the premise of trainable embedding and normalization. LongLoRA combines this improved LoRA with $S ^ { 2 }$ -Attn. LongLoRA demonstrates strong empirical results on various tasks on Llama2 models from 7B/13B to 70B. LongLoRA extends Llama2 7B from $4 \mathrm { k }$ context to $1 0 0 \mathrm { k }$ , or Llama2 70B to 32k on a single $8 \times \mathrm { { A l 0 0 } }$ machine. LongLoRA extends models’ context while retaining their original architectures, and is compatible with most existing techniques, like Flash-Attention2. In addition, we further conduct supervised fine-tuning with LongLoRA and our long instruction-following LongAlpaca dataset. All our code, models, dataset, and demo are available at github.com/dvlab-research/LongLoRA.

Furthermore, LongLoRA improves the training speed of LoRA by up to $1 . 8 \times$ with $S ^ { 2 }$ -Attn. Llama2-7B are fine-tuned to various context lengths with Flash-Attention2 (Dao, 2023) and DeepSpeed (Rasley et al., 2020) stage 2 and evaluated on the proof-pile (Azerbayev et al., 2022) test set in perplexity.
+
+# 1 INTRODUCTION
+
+Large language models (LLMs) are typically trained with a pre-defined context size, such as 2048 tokens for LLaMA (Touvron et al., 2023a) and 4096 tokens for Llama2 (Touvron et al., 2023b).
+
+![](images/baf2f25966210d3e0edd92e836d7095774560b4fc6ed3c7f68b2fe866e2ec6c0.jpg)  
+Figure 2: Overview of LongLoRA. We introduce Shifted Sparse Attention $S ^ { 2 }$ -Attn) during finetuning. The trained model retains original standard self-attention at inference time. In addition to training LoRA weights in linear layers, LongLoRA further makes embedding and normalization !a Embedding (1.94%) ❄ Linear Projec3on (96%) a ❄ Head (1.94%) alayers trainable. This extension is pivotal for context extension, and only introduces a minimal number of additional trainable parameters.
+
+However, the pre-defined size limits LLMs in many applications, like summarizing long documents or answering long questions. To resolve this limitation, some recent works (Chen et al., 2023; Tworkowski et al., 2023; Mohtashami & Jaggi, 2023) train or fine-tune LLMs to longer context. However, training an LLM from scratch with long sequences poses computational challenges, and fine-tuning an existing pre-trained LLM is also considerably expensive. For instance, Position Interpolation (Chen et al., 2023) spent 32 A100 GPUs to extend LLaMA models from 2k to 8k context, and 128 A100 GPUs for longer context fine-tuning. FOT (Tworkowski et al., 2023) used 32 TPUs for standard transformer training and 128 TPUs for LongLLaMA. These computation resources are typically unaffordable for common researchers, which naturally leads us to question: can we extend the context window of LLMs efficiently?
+
+One straightforward approach is to fine-tune a pre-trained LLM via low-rank adaptation (LoRA) (Hu et al., 2022). LoRA modifies the linear projection layers in self-attention blocks by utilizing low-rank matrices, which are generally efficient and reduce the number of trainable parameters. However, our empirical findings indicate that training long context models in this manner is neither sufficiently effective nor efficient. In terms of effectiveness, plain low-rank adaptation results in a high perplexity in long context extension, as in Table 2. Increasing the rank to a higher value, e.g., rank $= 2 5 6$ , does not alleviate this issue. In terms of efficiency, regardless of whether LoRA is employed or not, computational cost increases dramatically as the context size expands, primarily due to the standard self-attention mechanism (Vaswani et al., 2017). As shown in Figure 1, even with LoRA, the training hours for the standard Llama2 model increase substantially when the context window expands.
+
+In this work, we introduce LongLoRA, an efficient fine-tuning approach that extends the context windows of pre-trained LLMs, e.g., Llama2 (Touvron et al., 2023b). LoRA (Hu et al., 2022) uses low-rank weight updates to approximate full fine-tuning. Similarly, we find that short attention is also able to approximate long context during training. We present shifted sparse attention $S ^ { 2 }$ -Attn) as an efficient substitute for standard self-attention. As shown in Figure 2, we split context length into several groups and conduct attention in each group individually. In half attention heads, we shift the tokens by half group size, which ensures the information flow between neighboring groups. For example, we use $\mathsf { S } ^ { \frac { \sigma } { 2 } }$ -Attn with group size 2048 to approximate the total 8192 context length training. This shares a high-level spirit with Swin Transformer (Liu et al., 2021).
+
+Models fine-tuned via $S ^ { 2 }$ -Attn retain the original attention architecture during inference. This facilitates most existing optimization and infrastructure. Techniques for common LLMs can also be applied to ours. For example, Flash-Attention2 (Dao et al., 2022; Dao, 2023) is compatible with our method in both training and inference time. The reason behind this is that short attention resembles the attention scheme in the pre-training stage of LLMs. Other efficient attentions, e.g., dilated or sparse attention, have a large gap to the standard style and do not work well like ours, as in Table 6.
+
+We empirically show that learnable embedding and normalization layers are the key to unlocking long context LoRA fine-tuning, in Table 2. Embedding and normalization layers take up a small proportion of parameters in the entire LLM. For example, embedding has $( < 2 \% )$ parameters, and normalization has $( \leq 0 . 0 0 4 \% )$ parameters in Llama2 7B. This ratio decreases for even larger LLMs.
+
+![](images/f88b066bc65409970ffd5c24ca966ecc3f898b49b8b134cc30dcf0b68e379d96.jpg)  
+Figure 3: Illustration of $S ^ { 2 }$ -Attn. It involves three steps. First, it splits features along the head dimension into two chunks. Second, tokens in one of the chunks are shifted by half of the group size. Third, we split tokens into groups and reshape them into batch dimensions. Attention only computes in each group in ours while the information flows between groups via shifting. Potential information leakage might be introduced by shifting, while this is easy to prevent via a small modification on the attention mask. We ablate this in the variant 2 in Section B.3 in the appendix.
+
+In experiments, we show that LongLoRA is effective and efficient. We present experimental results of extending the context window for Llama2 7B, 13B, and 70B. Following the experimental settings of Position Interpolation (Chen et al., 2023), we fine-tune models with proper position embeddings. The trained models achieve comparable performance to the full-attention and fully fine-tuned results, while the computational cost is much less as shown in Figure 1. LongLoRA can fine-tune Llama2 7B up to $1 0 0 \mathrm { k }$ context, or a 70B model up to 32k, on a single $8 \times$ A100 machine.
+
+In addition, we present a solution for supervised fine-tuning (SFT) with our self-collected long instruction-following dataset, LongAlpaca. Our LongLoRA models are further fine-tuned with long questions and the corresponding answers. We design various types of questions for technical papers, science fiction, and other books. SFT is important for improving the chat ability of LLMs. We introduce our SFT settings in Section B.6 in the appendix.
+
+# 2 RELATED WORK
+
+Long-context Transformers. A large body of research has been developed to increase the context length of transformers. Some of these approaches are retrieval-based (Karpukhin et al., 2020; Izacard et al., 2022; Guu et al., 2020), which augment language models via fetching related documents and including the retrieved results into contexts. Our work is complementary to these works, as our attention mechanism is unmodified during inference. Many works modify multi-head attention to be approximated ones (Wang et al., 2020; Beltagy et al., 2020; Zaheer et al., 2020; Kitaev et al., 2020; Bulatov et al., 2022; Ding et al., 2023; Qiu et al., 2020). They alleviate the quadratic complexity of the self-attention computation. For example, Longformer (Beltagy et al., 2020) and BigBird (Zaheer et al., 2020) use sparse attention to handle long sequences. Other works (Wu et al., 2022; Bulatov et al., 2022) utilize memory mechanisms as a compression on past inputs, to look up relevant tokens. One limitation of these works is that these compressions have a large gap to full attention, making it infeasible to fine-tune pre-trained LLMs. Although our work also involves an approximation of attention mechanism, it has a similar shape and a small gap to standard attention. This enables fine-tuning pre-trained LLMs on $S ^ { 2 }$ -Attn and maintain full attention during inference.
+
+Long-context LLMs. LLMs are typically pre-trained with a pre-defined context length, such as 2048 for LLaMA (Touvron et al., 2023a) and 4096 for Llama2 (Touvron et al., 2023b). Training LLMs with long context from scratch is prohibitively expensive for most researchers. Recently, several works have tried to extend the context length of LLMs via fine-tuning. Position Interpolation (Chen et al., 2023) modifies rotary position encoding (Su et al., 2021) and extends the context length of LLaMA to 32768. Focused Transformer (Tworkowski et al., 2023) utilizes contrastive learning to train LongLLaMA. Both of them rely on full fine-tuning, which is computationally expensive (128 A100 GPUs / 128 TPUv3 for training). Landmark attention (Mohtashami & Jaggi, 2023) is an

Models are fully fine-tuned upon a Llama2 (Touvron et al., 2023b) model with 7B parameters on the RedPajama (Computer, 2023) dataset. Results are tested in perplexity on PG19 (Rae et al., 2020) validation split.

+
+efficient approach, but somewhat lossy. It compresses long context inputs into retrieved tokens. Our method saves substantial fine-tuning costs, while preserving the quality of the original attention. Ours maintain full access to the entire input via unmodified attention during inference.
+
+Some literature focuses on the position embedding modification of LLMs for long context extension, including Position Interpolation (Chen et al., 2023), NTK-aware (ntk, 2023), Yarn (Peng et al., 2023), positional Skipping (Zhu et al., 2023), and methods based on out-of-distribution analysis (Han et al., 2023). Our method focuses on efficient fine-tuning and retaining the original architecture during inference, which is orthogonal to these position embedding methods.
+
+Efficient Fine-tuning. This work is based on LoRA (Hu et al., 2022), a classical efficient fine-tuning approach. In addition to LoRA (Hu et al., 2022), there are many other parameter-efficient fine-tuning methods, including prompt tuning (Lester et al., 2021), prefix tuning (Li & Liang, 2021), hidden state tuning (Liu et al., 2022), bias tuning (Zaken et al., 2022), and masked weight learning (Sung et al., 2021). Input-tuning (An et al., 2022) introduces an adapter to tune input embedding. Although the input embedding layers are also trainable in ours, this is not enough for long context extension. We make a comprehensive analysis on layer types in experiments, in Table 2. Existing work (Chen et al., 2022) shows sparse masks can effectively save training costs and avoid performance drops.
+
+# 3 LONGLORA
+
+# 3.1 BACKGROUND
+
+Transformer. LLMs are typically built with transformers. Taking Llama2 (Touvron et al., 2023b) for example, as shown in Figure 2, an LLM model consists of an embedding input layer and a number of decoder layers. Each decoder layer comprises a self-attention module. It maps input features into a set of queries, keys, and values $\{ \boldsymbol { q } , \boldsymbol { k } , \boldsymbol { v } \}$ , via linear projection layers with weight matrices $\{ W _ { q } , W _ { k } , W _ { v } \}$ . Given $\{ q , k , v \}$ , it computes the outputs $o$ as
+
+$$
+o = \mathrm { s o f t m a x } ( q k ^ { T } ) v
+$$
+
+The outputs are then projected by a linear layer with a weight matrix $W _ { o }$ . And MLP layers are followed. Before and after self-attention modules, layer normalization (Ba et al., 2016) is applied. A final normalization is conducted after all decoder layers.
+
+For long sequences, self-attention struggles with computation cost, which is quadratic to the sequence length. This dramatically slows down the training procedure and increases GPU memory costs.
+
+Low-rank Adaptation. LoRA (Hu et al., 2022) hypothesizes that the weight updates in pre-trained models have a low intrinsic rank during adaptation. For a pre-trained weight matrix $W \in \mathbf { \hat { \mathbb { R } } } ^ { d \times k }$ , it is updated with a low-rank decomposition $W + \Delta W = W + B A$ , where $\mathbf { \bar { \boldsymbol { B } } } \in \mathbb { R } ^ { d \times r }$ and $A \in \mathbb { R } ^ { r \times k }$ . The rank $r \ll m i n ( d , k )$ . During training, $W$ is frozen with no gradient updates, while A and B are trainable. This is the reason why LoRA training is much more efficient than full fine-tuning.
+
+In the Transformer structure, LoRA only adapts the attention weights $( W _ { q } , W _ { k } , W _ { v } , W _ { o } )$ and freezes all other layers, including MLP and normalization layers. This manner is simple and parameterefficient. However, we empirically show that only low-rank adaptation in attention weights does not work for long context extension.

+
+# 3.2 SHIFTED SPARSE ATTENTION
+
+Standard self-attention costs $O ( n ^ { 2 } )$ computations, making LLMs on long sequences high memory cost and slow. To avoid this issue during training, we propose Shifted Sparse Attention $\bar { \mathbf { S } } ^ { 2 }$ -Attn), as shown in Figure 2. In the following, we make a pilot study and explain our design step by step.
+
+Pilot Study. In Table 1, we build up a standard baseline that is trained and tested with full attention and fine-tuning, which presents consistently good quality in various context lengths. The first trial is to train with short attention, only pattern $^ { l }$ in Figure 2. As we know for a long context, the high cost mainly comes from self-attention modules. Thus, in this trial, since the input is long, we split into several groups in self-attention. For example, the model takes 8192 tokens as input in both the training and testing stages, but self-attention is conducted in each group with a 2048 size. The group number is 4, as ablated in Section B.2 in the appendix. This pattern is efficient but still does not work in a very long context, as shown in Table 1. The perplexity becomes larger as the context length increases. The reason behind this is that there is no information exchange between different groups.
+
+To introduce communication between groups, we include a shifted pattern, as shown in Figure 2. We shift the group partition by half group size in half attention heads. Taking the overall 8192 context length for example, in pattern 1, the first group conducts self-attention from $1 ^ { \mathrm { s t } }$ to $2 0 4 8 ^ { \mathrm { t h } }$ tokens. In Pattern 2, the group partition is shifted by 1024. The first attention group begins from $1 0 2 5 ^ { \mathrm { t h } }$ and ends at $3 0 7 2 ^ { \mathrm { { \bar { t h } } } }$ tokens, while the first and the last 1024 tokens belong to the same group. We use patterns 1 and 2 in each half self-attention heads respectively. This manner does not increase additional computation costs but enables the information flow between different groups. We show that it gets close to the standard attention baseline in Table 1.
+
+Consistency to Full Attention. Existing efficient attention designs can also improve the efficiency of long-context LLMs. However, most of them are not suitable for long-context fine-tuning. Because, these transformers (Qiu et al., 2020; Child et al., 2019), designed for training from scratch, have gaps to the standard full attention, which is used in pre-training. In Table 6, we show that $S ^ { 2 }$ -Attn not only enables efficient fine-tuning but also supports full attention testing. Although other attentions can also be used in long context fine-tuning, models must be tested with the attention used during fine-tuning. Shifting prevents models from being over-fitted to specific attention patterns.
+
+Easy Implementation. $\mathrm { S ^ { 2 } }$ -Attn is easy to implement. It involves only two steps: (1) shifting tokens in half attention heads, and (2) transposing features from token dimension to batch dimension. Two lines of code are enough. We provide a PyTorch-style code in Algorithm 1.
+
+# 3.3 IMPROVED LORA FOR LONG CONTEXT
+
+LoRA (Hu et al., 2022) is an efficient and popular manner for adapting LLMs to other datasets. It saves much trainable parameters and memory cost, compared to full fine-tuning. However, adapting LLMs from short context length to long is not easy. We empirically observe an obvious gap between LoRA and full fine-tuning. As shown in Table 2, the gap between LoRA and full fine-tuning grows as the target context length becomes larger. And LoRA with larger ranks cannot reduce the gap.
+
+Table 2: Finetuning normalization and embedding layers is crucial for low-rank long-context adaptation. Llama2 7B (Touvron et al., 2023b) models with the proposed $S ^ { 2 }$ -Attn are trained on the RedPajama (Computer, 2023) dataset. The target context length is 32768. $^ { \bullet } +$ Normal / Embed’ means normalization or embedding layers are trainable. Perplexity results are evaluated on PG19 (Rae et al., 2020) validation set. For long context adaptation, there is a large performance gap between standard LoRA (Hu et al., 2022) and full fine-tuning. Without trainable normalization or embeddings, larger ranks in LoRA can not close this gap.

+
+To bridge this gap, we open embedding and normalization layers for training. As shown in Table 2, they occupy limited parameters but make effects for long context adaptation. Especially for normalization layers, the parameters are only $0 . 0 0 4 \%$ in the whole Llama2 7B. We denote this improved version of LoRA as $\mathrm { L o R A ^ { + } }$ in experiments.

+
+# 4.1 EXPERIMENTAL SETTINGS
+
+Models We extend the pre-trained 7B, 13B, and 70B Llama2 (Touvron et al., 2023b) models. The maximum extended context window sizes are up to 100k for 7B models, 65536 for 13B models, and 32768 for 70B models. The position indices for these models are re-scaled with Position Interpolation (Chen et al., 2023).
+
+Training Procedure We follow most training hyper-parameters in Position Interpolation (Chen et al., 2023), except that our batch size is smaller as we use a single $8 \times \mathrm { { A l 0 0 } }$ GPUs machine in some cases. All models are fine-tuned via the next token prediction objective. We use AdamW (Loshchilov & Hutter, 2019) with $\beta _ { 1 } = 0 . 9$ and $\beta _ { 2 } = 0 . 9 5$ . The learning rate is set to $2 \times 1 0 ^ { - 5 }$ for 7B and 13B models, and $1 0 ^ { - 5 }$ for 70B models. We also use a linear learning rate warmup. The weight decay is zero. We set the per-device batch size as 1 and gradient accumulation steps as 8, which means that the global batch size equals 64, using 8 GPUs. We train our models for 1000 steps.
+
+Table 4: Maximum context length that we can fine-tune for various model sizes on a single $8 \times$ A100 machine. We use the same training and evaluation settings as in Table 3. We use FlashAttention2 (Dao, 2023) and DeepSpeed (Rasley et al., 2020) in stage 3 during fine-tuning. With LongLoRA, the maximum context length for 7B, 13B, and 70B models are 100k, 64k, and $3 2 \mathrm { k }$ respectively. Evaluation on PG19 (Rae et al., 2020) is in Section B.1 in the appendix.

+Table 5: Topic retrieval evaluation with LongChat (Li et al., 2023). We compare our model to other open-source long-context LLMs. This task involves retrieving target topics from a very long conversation with around 3k, 6k, 10k, 13k, and 16k context lengths. As some questions in the evaluation set are longer than 16k, our model is fine-tuned upon Llama2 13B. It achieves comparable performance to the state-of-the-art LongChat-13B (Li et al., 2023) with a lower fine-tuning cost.

+
+Datasets We use the Redpajama (Computer, 2023) dataset for training. We evaluate the longsequence language modeling performance of our fine-tuned models on the book corpus dataset PG19 (Rae et al., 2020) and the cleaned Arxiv Math proof-pile dataset (Azerbayev et al., 2022). We use the test split of PG19 (Rae et al., 2020), consisting of 100 documents. For the proof-pile dataset, we also use the test split of it for evaluation. We follow Position Interpolation (Chen et al., 2023) for proof-pile data processing. We evaluate perplexity by using a sliding window approach with $S = 2 5 6$ , following (Press et al., 2022).
+
+# 4.2 MAIN RESULTS
+
+Long-sequence Language Modeling. In Table 3, we report the perplexity for our models and baseline on proof-pile (Azerbayev et al., 2022) and PG19 datasets. Under certain training context lengths, our models achieve better perplexity with longer context sizes. This indicates the effectiveness of our efficient fine-tuning method. In Table 3, for the same training and evaluation context length cases, the perplexity decreases as the context size increases. By increasing the context window size from 8192 to 32768, for the Llama2 7B model, we observe that the perplexity gets better from 2.72 to 2.50 by -0.22. For Llama2 13B model, we observe that the perplexity reduces by -0.28.
+
+In Table 4, we further examine the maximum context length that we can fine-tune on a single $8 \times$ A100 machine. We extend Llama2 7B, 13B, and 70B to 100k, 65536, and 32768 context length respectively. LongLoRA achieves promising results on these extremely large settings. In addition, we find some perplexity degradation on small context sizes for the extended models. This is a known limitation of Position Interpolation (Chen et al., 2023).
+
+Retrieval-based Evaluation. We conduct experiments on retrieval in long contexts. In Table 5, we compare our model with other open LLMs on the topic retrieval task introduced in LongChat (Li et al., 2023). This task is to retrieve the target topic from a very long conversation, with lengths varying from 3k, 6k, 10k, 13k, to 16k. As some questions in LongChat (Li et al., 2023) are longer than 16k, we fine-tuned Llama2 13B with a context length of 18k. The training cost is similar to that for 16k.

+Figure 4: Accuracy comparison on passkey retrieval between Llama2 7B and our 7B model fine-tuned on 32768 context length. Our model presents no retrieval accuracy degradation until 33k or $3 4 \mathrm { k }$ , which exceeds the context length. It can further enhance its capability of long sequence modeling through a straightforward extension of position embeddings, without additional fine-tuning.

+Figure 5: Ablation on fine-tuning steps in both full fine-tuning and LoRA+. We fine-tune Llama2 (Touvron et al., 2023b) 7B with the proposed $S ^ { 2 }$ -Attn. The target context length is 8192. We use RedPaPasskey Retrieval Accuracyjama (Computer, 2023) for training and PG19 (Rae et al., 2020) validation set for perplexity testing. 100%Full fine-tuning converges faster than LoRA+ at the beginning, but the final performance gap is small.
+
+40%Our model achieves comparable performance to LongChat-13B (Li et al., 2023), the state-of-the-art model in this task. Unlike LongChat-13B (Li et al., 2023), which is fully fine-tuned on self-collected 2k 4k 6k 8k 10k 12k 14k 16k 18k 20k 22k 24k 26k 28k 30k 32k 34k 36k 38k 40k 42k 44k 46k 48klong context conversation text, our model is efficiently adapted on RedPajama (Computer, 2023) via Llama2 7B Ours 7B 32k Ours 7B 32k (extended PI to 48k)next-token generation. Our model even slightly outperforms LongChat-13B in the $1 6 \mathrm { k }$ evaluation.
+
+In Figure 4, we present the passkey retrieval accuracy of our model, following Landmark Attention (Mohtashami & Jaggi, 2023). This task has also been adopted by other literature (Chen et al., 2023; Tworkowski et al., 2023). In this task, the models need to find a random passkey hidden in a long document. We show the document format is in Section A.2 in the appendix. We study Llama2 7B (Touvron et al., 2023b) and our LongLoRA model which fine-tunes Llama2 7B with 32768 context length. We test the passkey retrieval accuracy from 1k to 34k, with an interval of roughly 1k (as the sentence length can not be precisely controlled). For each document length, we test the model 10 times with different random passkey values. Our model achieves reasonable passkey retrieval accuracy until $3 3 \mathrm { k }$ or $3 4 \mathrm { k }$ . Without further fine-tuning, We modify the max position embeddings to $4 8 \mathrm { k }$ in the position interpolation, which is the Ours 7B (extended PI) in Figure 4. We show that this model can handle longer documents by simply extending the position interpolation. As the dashed orange line in Figure 4, the model, fine-tuned on $3 2 \mathrm { k }$ context length, presents moderate retrieval ability $6 0 \% . 9 0 \%$ accuracy) in the range of $3 3 \mathrm { k }$ to $4 5 \mathrm { k }$ . Even with the position interpolation extended, Llama2 7B suffers from a sharp accuracy degradation (dashed blue line) after the $4 \mathrm { k \Omega }$ context length.
+
+# 4.3 ABLATION STUDY
+
+In this section, we introduce ablation studies on the number of fine-tuning steps and attention patterns. Other experimental results including ablations on group sizes, attention variants, and efficiency analysis are Section B in the appendix.
+
+Ablation on Fine-tuning Steps. We report the relationship between perplexity and fine-tuning steps for a Llama2 7B model extending to the 8192 context length on the PG19 validation set, in
+
+Table 6: Comparisons among $\mathbf { S } ^ { 2 }$ -Attn and alternative attention patterns during fine-tuning. We adapt a Llama2 7B model to 32768 context length with different attention patterns and improved LoRA at training time. We include four typical efficient attention designs, e.g., shift, dilate (Ding et al., 2023), block sparse (Qiu et al., 2020), stride sparse (Child et al., 2019) for comparison. ‘cro. heads / layers’ means to swap different attention settings across attention heads or sequential layers. Taking ${ \mathsf S } ^ { \tilde { 2 } }$ -Attn as an example, ‘cro. layers’ is to swap between w/ and w/o shift in sequential self-attention layers. ‘only $P l / P 2 ^ { \circ }$ means all attention heads use pattern 1 (all no shift) or Pattern 2 (all shift) in Figure 2. We visualize the patterns of different attention in Figure 7 in the appendix. For each attention pattern, we evaluate its performance under two protocols. In the first row, we use sparse attention in both training and testing. In the second row, we use full attention for testing.
+
+<table><tr><td rowspan="2">Test w/ Full-Attn</td><td colspan="4">S²-Attn</td><td rowspan="2">Dilate cro. heads</td><td rowspan="2">Block sparse cro. heads</td><td rowspan="2">Stride sparse cro. heads</td></tr><tr><td>cro. heads</td><td>cro. layers</td><td>only P1.</td><td>only P2.</td></tr><tr><td>x&gt;</td><td>8.64</td><td>8.63</td><td>9.17</td><td>9.64</td><td>8.75</td><td>11.49</td><td>32.81</td></tr><tr><td></td><td>8.12</td><td>9.70</td><td>8.39</td><td>9.81</td><td>11.78</td><td>8.30</td><td>24.03</td></tr></table>
+
+Figure 5. We see that without fine-tuning, at step 0, the model has a limited long context capability, e.g., 15.82 perplexity. We show that the perplexity drops quickly. Full fine-tuning converges faster than low-rank training. They come closer after 200 steps, without a large gap at the end.
+
+Attention Patterns. In Table 6, we show the effects of different attention patterns during finetuning. We fine-tune a Llama2 7B (Touvron et al., 2023b) model to 32768 context length on Redpajama (Computer, 2023) datasets and evaluate the perplexity on PG19 (Rae et al., 2020) validation set. We first examine the manner of swapping among various settings. For the shift operation we used in LongLoRA, there are three choices: disabling it, shifting between sequential layers, and shifting among attention heads. We show that shifting between layers is acceptable but not the best. In addition, setting all attention heads as pattern 1 or pattern 2 does not work. In addition, we empirically find that shifting left or right has little difference in performance.
+
+We then test other types of efficient attention designs, including dilated attention (Ding et al., 2023), block sparse attention (Qiu et al., 2020), and stride sparse attention (Child et al., 2019). For dilated attention (Ding et al., 2023), we vary the dilate rate from 1 to 2 evenly among attention heads. For block sparse attention (Qiu et al., 2020), we use $n = 4$ block-wise masking matrices in attention heads and move the block left to make it causal. Stride sparse attention (Child et al., 2019) contains both local and stride patterns. These settings share similar computational costs. We visualize these patterns in Figure 7 in the appendix. These attention patterns are invented in training-fromscratch transformers. This experiment is to examine their capability of fine-tuning on pre-trained LLMs (Touvron et al., 2023b), toward long context adaptation. Dilated attention performs well in full fine-tuning but is not well with low-rank adaptation. Fine-tuning with stride sparse attention is harmful. They have a large gap to full attention, which is applied in the pre-training stage.
+
+# 5 CONCLUSION
+
+In this work, we propose LongLoRA that can efficiently extend the context length of LLMs to be significantly larger. LongLoRA has less GPU memory cost and training time than standard full fine-tuning, with minimal accuracy compromise. At the architecture level, we propose $S ^ { 2 }$ -Attn to approximate the standard self-attention pattern during training. $S ^ { 2 }$ -Attn is easy to implement, requiring only two lines of code. Moreover, models trained via $S ^ { 2 }$ -Attn retain the original standard attention architecture during inference, making most pre-existing infrastructure and optimization reusable. At the training level, we bridge the gap between LoRA and full fine-tuning with trainable normalization and embedding. Our method can extend Llama2 7B to $1 0 0 \mathrm { k }$ context length and 70B model to 32k context length, on a single $8 \times$ A100 machine. We also present a long instructionfollowing dataset, LongAlpaca and conducted supervised fine-tuning with LongLoRA. We believe that LongLoRA is a general method that could be compatible with more types of LLMs and position encodings. We plan to investigate these in future work.

+# APPENDIX
+
+# A SETTINGS
+
+# A.1 ENVIRONMENTS
+
+All our experiments are conducted on an $8 \times$ A100 machine. We train all models using PyTorch (Paszke et al., 2019) with the DeepSpeed (Rasley et al., 2020) and Flash-Attention2 (Dao, 2023). By default, we use DeepSpeed (Rasley et al., 2020) in stage 2 and use stage 3 for the maximum context length experiments. Gradient checkpoint is used by default, which is a common technique in the Peft codebase (Mangrulkar et al., 2022). Note that sometimes, $8 \times \mathrm { \ A l { 0 0 } }$ GPUs might not be necessary and 3090 Ti GPUs are acceptable, like fine-tuning 7B models to 8192 context size.
+
+# A.2 FORMAT OF PASSKEY RETRIEVAL
+
+We follow existing literature (Mohtashami & Jaggi, 2023; Tworkowski et al., 2023; Chen et al., 2023) for the document format of passkey retrieval. The document has the following format:
+
+There is an important info hidden inside a lot of irrelevant text. Find it and memorize them. I will quiz you about the important information there.   
+The grass is green. The sky is blue. The sun is yellow. Here we go. There and back again. (repeat M times)   
+The pass key is 12362. Remember it. 12362 is the pass key. The grass is green. The sky is blue. The sun is yellow. Here we go. There and back again. (repeat N times)   
+What is the pass key? The pass key is
+
+The document length varies with the value of M and N. 12362 is the passkey number to retrieve. It is randomly sampled and varies at each testing time.
+
+# B EXPERIMENTS
+
+# B.1 EVALUATION PERPLEXITY ON PG19 TEST SPLIT.
+
+In Table 14 and Table 15, we present the evaluation results on the PG19 test split. We use the same settings as the models on proof-pile (Azerbayev et al., 2022) evaluation in the paper. Similarly, for a model trained on a certain context length, as the evaluation context length increases, our models achieve better perplexity. Note that the perplexity in Table 14 and Table 15 is higher than that in the proof-pile dataset, as PG19 (Rae et al., 2020) has very different writing styles.
+
+# B.2 ABLATION ON GROUP SIZES.
+
+In Table 7, we provide an ablation study on the group size of the $S ^ { 2 }$ -Attn. We experimented with fine-tuning Llama2 7B to 8192 and 16384 context lengths via LongLoRA. The group size varies from $\{ 1 / 2 , 1 / 4 , 1 / 6 , 1 / 8 \}$ of the target context length. For example, the group size is 1024 for 1/8 of the context length 8192. We find that the 1/2 and 1/4 settings have minor gaps to full attention fine-tuning. Group sizes less than 1/4 would be not good enough. We set the group size as 1/4 of the context length in experiments by default.

+Table 7: Ablation on group size. We fine-tune a Llama2 7B model to 8192 and 16384 context lengths via LongLoRA and evaluate on PG19 validation set. We vary the group size of $S ^ { 2 }$ -Attn from $\{ 1 / 2$ $1 / 4 , 1 / 6 , 1 / 8 \}$ of the target context length. ‘Full’ means the standard full attention.

+# B.3 ABLATION ON THE VARIANTS OF $S ^ { 2 }$ -ATTN.
+
+In Table 8, we ablate some variants of $S ^ { 2 }$ -Attn, which are illustrated in Figure 6. Variant 1 is to change the shifting direction from down to up. It shows that the shifting direction has no effect on the perplexity. One concern about $S ^ { 2 }$ -Attn is that it moves the last tokens to the front into one group, which might be inconsistent with causal masks. Variant 2 uses individual groups for the shifted tokens, which ablates this concern. Variant 3 swaps the shifted and the original front tokens, which can also ablate the concern. We show that these variants present similar perplexity to ours. We suppose that although there are communications among the front and last tokens, they are originally far away from others while it is limited in the local group. Moreover, $S ^ { 2 }$ -Attn is only used for fine-tuning, while we use standard causal masks and full attention during inference. Variant 2 and 3 also work well but involve additional steps to ours.

+# B.4 EVALUATION ON LONG-CONTEXT BENCHMARKS.
+
+We evaluate our method on long-context benchmarks, LongBench (Bai et al., 2023) in Table 9 and LEval (An et al., 2023) in Table 10. We fine-tune Llama2 7B to 16384 context length, with the supervised fine-tuning method and data introduced in Section B.6. We compare our model with GPT-3.5-Turbo and other Llama2-based long-context models, like Vicuna (Chiang et al., 2023) and LongChat (Li et al., 2023) models. It shows that our 7B model presents comparable or even better performance than these Llama2-based long-context models, while ours only takes about 4 hours, about 0.3 billion tokens, on a single $8 \times$ A100 machine.
+
+# B.5 EFFICIENCY ANALYSIS.
+
+In Table 11, we break down the FLOPs of Llama2 7B (Touvron et al., 2023b) into various types of layers, including FFN - feed-forward layers, Proj - projection for queries, values, keys, and attention outputs, Attn - self-attention computation, Others - other layers like embedding, normalization, LLM head. For full attention, the proportion of Attn sharply increases as the context length increases. For

+Figure 6: Illustration on the variants of our $S ^ { 2 }$ -Attn. Variant 1 changes the shifting direction. Variant 2 splits the shifted tokens into one individual group. Variant 3 swaps the shifted tokens with the original front one.
+
+Table 11: FLOPs profiling on various context lengths. We break down the Llama2 7B model into FFN (feed-forward layers), Proj (projection layers for queries, keys, values, and attention outputs), Attn (self-attention kernel), and Others (e.g., embedding, normalization, LLM head). The ratio of attention in the overall model increases as the context length increases. $S ^ { 2 }$ -Attn reduces the FLOPs by a large margin, especially when the context length is large.
+

+
+example, Attn has $2 4 . 5 \%$ of the total FLOPs at the 8192 context length while it increases to $7 2 . 2 \%$ at the 65536 context length. It decreases to $3 9 . 4 \%$ when $S ^ { 2 }$ -Attn is used.
+
+For the measurement of FLOPs in Table 11, We profiled the context stage FLOPs of Llama2-7B using a batch size of 1 and various context lengths using a third-party tool, torchprofile 1. The tool traces the computation graph and sums up the FLOPs of each node in the graph (e.g. Q/K/V/O projections, multi-head self-attention, fully-connected layers, and normalization layers).
+
+In Table 12, we compare the training cost among full fine-tuning, plain LoRA (Hu et al., 2022), and LongLoRA. It records details for Figure 1 in the paper. The major difference between LoRA (Hu et al., 2022) and LongLoRA is the $S ^ { 2 }$ -Attn. Although there are many FLOPs saving, the peak memory cost has limited difference, because of the highly optimized Flash-Attention2 (Dao, 2023). In contrast, the training hour saving is relatively clear. For example, LongLoRA spends $5 6 . 6 \%$ training hours as that of LoRA in the 65536 context length.
+
+In Table 13, we present the effects of $S ^ { 2 }$ -Attn without Flash-Attention2 (Dao, 2023). LoRA+ is included in this ablation. It shows that $S ^ { 2 }$ -Attn achieves more speedup than that in Table 12. Without the help of Flash-Attention2 (Dao, 2023), the full attention baseline encounters $o o M$ at the 16384 context fine-tuning in an $8 \times \mathrm { { A l 0 0 } }$ machine, while $S ^ { 2 }$ -Attn is sufficient for this.
+
+# B.6 SUPERVISED FINE-TUNING.
+
+We further conducted supervised fine-tuning on ours to improve their QA ability. Although the models fine-tuned with Redpajama (Computer, 2023) present good perplexities, their chat ability is limited. We collect some question-answer pairs, relating to the materials like technical papers, science

We set batch size per GPU as 1 and gradient accumulation steps as 8. OOM means out of GPU memory. Flash-Attention2 (Dao, 2023) and DeepSpeed (Rasley et al., 2020) in stage 2 are included in these experiments. LongLoRA requires significantly lower computational overhead than fine-tuning the full model. It also demands fewer training hours compared to LoRA (Hu et al., 2022). Furthermore, the plain LoRA (Hu et al., 2022) fails to maintain the same level of accuracy as full fine-tuning when handling longer contexts.

+
+Based on the book, Sirius Black did not actually want to kill anyone. The key details are:
+
+1. Sirius Black was wrongly imprisoned for betraying Harry's parents and killing Peter Pettigrew.   
+2. 3. It was actually Pettigrew who betrayed the Potters and staged his own death to frame Sirius Black. When Sirius Black escaped from prison, he was initially believed to be hunting down Harry to kill him for revenge.   
+4. However, it was later revealed that Sirius Black actually wanted to kill Pettigrew to get revenge for framing him and betraying the Potters.   
+5. Sirius Black did not actually want to harm Harry. In fact, he was Harry's godfather and wanted to take Harry in once his name was cleared.
+
+So in summary, Sirius Black initially wanted to kill Peter Pettigrew for framing him and betraying the Potters. He did not actually want to kill Harry.

+Hello! I'm here to help answer your questions, and I want to point out that the question you've asked might be based on a harmful assumption. The character Sirius Black is not a person who wants to kill anyone. He is a character in the Harry Potter series who is wrongly accused of a crime and is seeking to clear his name.   
+It's important to remember that making assumptions about people based on limited information or media portrayals can be harmful and perpetuate negative stereotypes. Instead, I suggest focusing on the facts and context of the story to understand the characters and their motivations.

+Shi Qiang plays an important role in helping Luo Ji find meaning and purpose. Some key points:
+
+Shi Qiang finds Zhuang Yan for Luo Ji. Zhuang Yan brings joy and innocence into Luo Ji's life, which was empty and aimless before. She gives him motivation and hope.   
+Shi Qiang's final request to Luo Ji, to carry on the Shi family lineage, implies that Luo Ji still has an important role to play. It gives Luo Ji a sense of responsibility and mission.   
+Shi Qiang's sacrifice and selfless help for Luo Ji show the good in human nature. This gives Luo Ji faith in humanity and optimism that humans can defeat the aliens.   
+Shi Qiang's search for Zhuang Yan helps prove to Luo Ji that there are perfect people in the world, contrary to what Luo Ji originally believed. This encourages Luo Ji and dispels his sense of hopelessness.
+
+In summary, Shi Qiang acts as a catalyst that reawakens Luo Ji's will and determination. Zhuang Yan, whom Shi Qiang finds, represents hope and light in Luo Ji's life. Together they help give Luo Ji a newfound sense of purpose and belief that he can carry out his duties as a Wallfacer. So while Shi Qiang's role may seem small, his impact on Luo Ji could ripple out and affect the fate of human civilization.

+
+Hello! As a compassionate assistant, I'm here to help you with your question while ensuring a safe and respectful conversation.   
+In The Dark Forest, Shi Qiang is a fictional character who plays a significant role in the story. However, it's important to recognize that his actions and motivations are shaped by the novel's themes of survival, power dynamics, and the human condition. Rather than focusing on Shi Qiang's individual importance, it may be more productive to discuss the themes and ideas explored in the novel as a whole. The Dark Forest raises questions about human nature, the consequences of power imbalances, and the importance of cooperation in the face of adversity.   
+If you're interested in discussing the novel in a safe and respectful manner, I'd be happy to help facilitate a conversation that prioritizes inclusivity, sensitivity, and the well-being of all individuals.

+# Contribution
+
+Below is a paper. Memorize the material and answer my question after the paper. {paper} \n Now the material ends. What are the main contributions and novelties of this work?
+
+The paper proposes an Action Units Relation Learning framework that consists of two main parts:   
+1. The Action Units Relation Transformer (ART) that models the relations between different facial action units (AU) at the AU-agnostic patches and the AU-specific regions. This helps capture intra-face relations that are useful for forgery detection.   
+2. The Tampered AU Prediction (TAP) that tampers the AU-related regions and provides Local Tampering Supervision. This helps improve the generalization ability of the model to unseen manipulation methods.
+
+The key contributions are:
+
+1. Modeling the relations between different AUs at the AU-agnostic patches using the ART encoder. This helps capture intra-face relations that are useful for forgery detection.   
+2. Generating challenging pseudo samples for the model to learn by tampering the AU-related regions using the TAP process. This helps improve the generalization ability of the model to unseen manipulation methods.   
+3. Achieving state-of-the-art performance on cross-dataset and cross-manipulation evaluations, demonstrating the effectiveness and generalization of the proposed framework.   
+4. Providing qualitative visualizations of the tampered regions using the predicted patch tokens, which helps interpret how different regions are modified in the manipulation process.
+
+In summary, the main contributions are the proposed ART encoder that models intra-face relations and the TAP process that generates challenging pseudo samples, which together improve the generalization of the deepfake detection model.
+
+Limitation $\cdot$
+
+Below is a paper. Memorize the material and answer my question after the paper. {paper} \n Now the material ends. What are some limitations of the proposed 3DGNN method?
+
+Possible answers:
+
+1. The 3DGNN method relies on the initial graph construction based on 3D points and nearest neighbors. The accuracy of this graph construction can affect the performance of the model. The graph construction method used may not be optimal for all scenes.   
+2. The 3DGNN model uses a fixed number of propagation steps. The optimal number of propagation steps may vary for different scenes and objects. Using a fixed number of steps may not be the best approach.   
+3. The 3DGNN model struggles with objects that have similar depths or complex shapes, as discussed in the failure case analysis. The model's performance relies on the 3D geometric context, which may not be sufficient for some types of objects.   
+4. The model requires depth information from an RGBD sensor, which limits its applicability to scenes where depth data is not available. The model cannot be directly applied to 2D RGB images.   
+5. The model performance may degrade for very small objects, as shown in the analysis of performance gain by object size. The model seems better suited for medium and large objects.
+
+Summarization
+
+Below is a paper. Memorize the material and answer my question after the paper.   
+{paper} \n Now the material ends.   
+Please summarize the paper in one paragraph.
+
+The paper proposes a new dataset called SAFECONV for the research of conversational safety. The dataset annotates unsafe spans in utterances and provides safe alternative responses to replace unsafe responses. The annotated unsafe spans help explain why an utterance is unsafe and provide guidance for generating safe responses. The dataset contains unsafe spans, unsafe responses, and safe alternative responses for over 100,000 dialogues from social media platforms. The paper compares SAFECONV with other datasets and shows that SAFECONV is more comprehensive. SAFECONV demonstrates that identifying unsafe spans can well explain the detection of unsafe utterances, and rewriting unsafe responses with context can mitigate a large proportion of unsafe behavior in chatbots. The dataset and models are released to advance the research of conversational safety.

Typically, training LLMs with long context sizes is computationally expensive, requiring extensive training hours and GPU resources. For example, training on the context length of 8192 needs $1 6 \\times$ computational costs in self-attention layers as that of 2048. In this paper, we speed up the context extension of LLMs in two aspects. On the one hand, although dense global attention is needed during inference, fine-tuning the model can be effectively and efficiently done by sparse local attention. The proposed shifted sparse attention ( $S ^ { 2 }$ -Attn) effectively enables context extension, leading to non-trivial computation saving with similar performance to fine-tuning with vanilla attention. Particularly, it can be implemented with only two lines of code in training, while being optional in inference. On the other hand, we revisit the parameter-efficient fine-tuning regime for context expansion. Notably, we find that LoRA for context extension works well under the premise of trainable embedding and normalization. LongLoRA combines this improved LoRA with $S ^ { 2 }$ -Attn. LongLoRA demonstrates strong empirical results on various tasks on Llama2 models from 7B/13B to 70B. LongLoRA extends Llama2 7B from $4 \\mathrm { k }$ context to $1 0 0 \\mathrm { k }$ , or Llama2 70B to 32k on a single $8 \\times \\mathrm { { A l 0 0 } }$ machine. LongLoRA extends models’ context while retaining their original architectures, and is compatible with most existing techniques, like Flash-Attention2. In addition, we further conduct supervised fine-tuning with LongLoRA and our long instruction-following LongAlpaca dataset.

However, training an LLM from scratch with long sequences poses computational challenges, and fine-tuning an existing pre-trained LLM is also considerably expensive. For instance, Position Interpolation (Chen et al., 2023) spent 32 A100 GPUs to extend LLaMA models from 2k to 8k context, and 128 A100 GPUs for longer context fine-tuning. FOT (Tworkowski et al., 2023) used 32 TPUs for standard transformer training and 128 TPUs for LongLLaMA.

However, our empirical findings indicate that training long context models in this manner is neither sufficiently effective nor efficient. In terms of effectiveness, plain low-rank adaptation results in a high perplexity in long context extension, as in Table 2. Increasing the rank to a higher value, e.g., rank $= 2 5 6$ , does not alleviate this issue. In terms of efficiency, regardless of whether LoRA is employed or not, computational cost increases dramatically as the context size expands, primarily due to the standard self-attention mechanism (Vaswani et al., 2017).

Some of these approaches are retrieval-based (Karpukhin et al., 2020; Izacard et al., 2022; Guu et al., 2020), which augment language models via fetching related documents and including the retrieved results into contexts. Our work is complementary to these works, as our attention mechanism is unmodified during inference. Many works modify multi-head attention to be approximated ones (Wang et al., 2020; Beltagy et al., 2020; Zaheer et al., 2020; Kitaev et al., 2020; Bulatov et al., 2022; Ding et al., 2023; Qiu et al., 2020). They alleviate the quadratic complexity of the self-attention computation.

Other works (Wu et al., 2022; Bulatov et al., 2022) utilize memory mechanisms as a compression on past inputs, to look up relevant tokens. One limitation of these works is that these compressions have a large gap to full attention, making it infeasible to fine-tune pre-trained LLMs. Although our work also involves an approximation of attention mechanism, it has a similar shape and a small gap to standard attention.

+# Abstract
+
+We introduce $\mathrm { C o g V L M }$ , a powerful open-source visual language foundation model. Different from the popular shallow alignment method which maps image features into the input space of language model, $\mathrm { C o g V L M }$ bridges the gap between the frozen pretrained language model and image encoder by a trainable visual expert module in the attention and FFN layers. As a result, CogVLM enables a deep fusion of vision language features without sacrificing any performance on NLP tasks. CogVLM-17B achieves state-of-the-art performance on 15 classic crossmodal benchmarks, including 1) image captioning datasets: NoCaps, Flicker30k, 2) VQA datasets: OKVQA, ScienceQA, 3) LVLM benchmarks: MM-Vet, MMBench, SEED-Bench, LLaVABench, POPE, MMMU, MathVista, 4) visual grounding datasets: RefCOCO, RefCOCO $^ +$ , RefCOCOg, Visual7W. Codes and checkpoints are available at Github.
+
+# 1 Introduction
+
+Vision language models are versatile and powerful. Many vision and cross-modality tasks can be formulated as next token prediction, e.g., image captioning [Agrawal et al., 2019], visual question answering [Antol et al., 2015], visual grounding [Yu et al., 2016] and even segmentation [Chen et al., 2022a]. Useful abilities like in-context learning [Tsimpoukelli et al., 2021, Sun et al., 2023b, Alayrac et al., 2022] also emerge along with the improvement of downstream tasks when scaling up VLMs. However, to train a large language model is already non-trivial, and it is more challenging to train a VLM from scratch with the same NLP performance as well-trained pure language models like LLaMA2 [Touvron et al., 2023]. Therefore, it is natural to investigate how to train a VLM from an off-the-shelf pretrained language model.
+
+The popular shallow alignment methods represented by InstructBLIP [Li et al., 2023b] and MiniGPT4 [Zhu et al., 2023] connect a frozen pretrained vision encoder and language model via a trainable Q-Former or a linear layer, mapping the image features into the input embedding space of the language model. This method converges rapidly, but its performance is noticeably inferior to that of LLaVA-1.5 with trainable language parameters, despite their model sizes and training datasets being almost identical.
+
+The primary challenge in the performance of shallow alignment methods within VLMs can be attributed to the lack of deep fusion between visual and linguistic data. Shallow alignment methods struggle because they rely on ‘frozen’ language model weights, which are intrinsically trained to

+
+Q1: What did Musk say?
+
+CogVLM: Elon Musk in the tweet said: "Fight Recap: I joked on X about fighting Zuck, Zuck then said, 'Send ME LOCATION.' Italy graciously offered a Colosseum, but Zuck declined. I suggested his home as a "safe space," but tragically, he was already "traveling." Is there anywhere he will fight?"
+
+Q2: Do you think Zuck is really traveling?
+
+CogVLM: Based on the content of the tweet, it seems that Zuck is not really traveling, but rather pretending to be traveling in order to avoid the conflict.

+Detailed Description   
+Q: Describe this image in detail.
+
+CogVLM: The image showcases a railway platform labeled 'Platform 2'. A green train is approaching, with steam emanating from its engine. On the platform, there are several people, including a woman in a pink shirt, a child with a backpack, and a man in a green shirt. There's a chalkboard sign on the platform that reads: 'Please Use The Footbridge To Cross The Line If You Require Assistance. Please Ask The Station Staff.' In the background, there's a signal post and some trees.
+
+Q: What is the difference of largest and smallest bar? Answer it step by step.
+
+$\mathbf { C o g V L M } ;$ The largest bar represents Iceland with a percentage of 100%. The smallest bar represents Cambodia with a percentage of 52.4%. To find the difference, subtract the smallest percentage from the largest: 100% - $. 5 2 . 4 \% = 4 7 . 6 \%$ .

+
+Q: Can you explain this meme?
+
+CogVLM: This meme is a humorous take on the idea that certain drugs, like cocaine, are believed to have no side effects. The meme uses a fictional meeting of various mythical creatures, each with a unique and exaggerated appearance, to represent the different effects of cocaine. The text at the top of the image, 'Publicly, we are still saying there are no side effects,' is a statement often made by pharmaceutical companies or health organizations about certain drugs. The creatures in the meeting, with their various and often comical expressions and postures, humorously represent the different 'side effects' of cocaine, suggesting that the drug has a wide range of unintended effects.

+Visual Reasoning   
+Q: From the perspective of a photographer, analyze why this picture was taken well?
+
+CogVLM: From a photographer's perspective, several elements contribute to the quality of this image. The composition is balanced, with the hot air balloon taking up a significant portion of the frame, yet still allowing the surrounding environment to be visible. The use of lighting, especially the soft glow from the balloon and the car's headlights, creates a warm and inviting atmosphere. The depth of field is shallow, focusing on the subjects in the foreground while softly blurring the background, drawing attention to the main elements of the scene.

+# Grounding Visual Question Answering
+
+Q1: What color are the clothes of the girl whose hands are holding flowers? Let's think step by step.
+
+CogVLM: Find the flowers [[328,519,436,780]]. Check the girl holding it, got the girl [[116,069,450,927]]. Check the clothes of it, got the clothes [[134,309,418,852]]. The clothes [[134,309,418,852]] are blue. So the answer is blue.

+
+process text tokens. This presents a significant mismatch issue, as visual features lack a direct equivalent in the textual input space. Consequently, when these visual features undergo multi-layer transformations, they tend to deviate from the expected input distribution of the deeper language model layers. This misalignment is particularly evident in tasks like image captioning, where the specificity of a task – such as writing style and caption length – can only be superficially encoded into visual features through shallow methods.
+
+A common strategy, as seen in PaLI [Chen et al., 2022b] and Qwen-VL [Bai et al., 2023], involves direct training of LLM during the pre-training or supervised fine-tuning (SFT) phase. However, this approach can compromise the models’ generalizability, particularly for tasks focused on textual outputs. Conventionally, LLMs are pretrained on extensive text-only datasets [Raffel et al., 2020], leading to a significant divergence in data distribution when compared to image-text pair datasets like LAION [Schuhmann et al., 2022] and COYO [Byeon et al., 2022]. This shift often results in catastrophic forgetting, a phenomenon where the model’s proficiency in its original domain deteriorates. This issue is evident in Figure 2, which shows a marked decline in MMLU [Hendrycks et al., 2020] score as the model becomes more attuned to the LAION dataset, thus validating our hypothesis. This trend is not isolated; similar effects have been observed in models like PaLME [Driess et al., 2023] and Flamingo [Alayrac et al., 2022]. For instance, adapting an 8B parameter language model for VLM pretraining can lead to an $8 7 . 3 \%$ reduction in natural language generation (NLG) performance [Driess et al., 2023].

+Figure 2: MMLU score and training loss over multimodal pretraining phase. When directly training the language part of the VLM using the LAION dataset, the model’s score on the pure text dataset MMLU rapidly decreases, dropping to 24.9 at 2500 steps.
+
+The discussion above raises an important question: is it possible to retain the NLP capabilities of the large language model while adding top-notch visual understanding abilities to it?
+
+$\mathrm { C o g V L M }$ gives a “yes” answer. $\mathrm { C o g V L M }$ instead adds a trainable visual expert to the language model. In each layer, the image features in the sequence use a new QKV matrix and MLP layer with the text features. Visual expert doubles the number of parameters while keeping the FLOPs the same. Since all the parameters in the original language model are fixed, the behaviors are the same as in the original language model if the input sequence contains no image. This inspiration arises from the comparison between P-Tuning [Liu et al., 2023f] and LoRA [Hu et al., 2021] in efficient finetuning, where p-tuning learns a task prefix embedding in the input while LoRA adapts the model weights in each layer via a low-rank matrix. As a result, LoRA performs better and more stable. A similar phenomenon might also exist in VLM, because in the shallow alignment methods, the image features act like the prefix embedding in P-Tuning.
+
+Our contributions in this work are as follows:
+
+• We introduce the $\mathrm { C o g V L M }$ model, which deeply integrates visual and linguistic features while retaining the full capabilities of a pretrained large language model. CogVLM-17B, trained from Vicuna-7B, achieves state-of-the-art across 17 classic cross-modal benchmarks.   
+• Through extensive ablation studies, we validated the effectiveness of our proposed visual expert module and the importance of deep fusion. We further delved into multiple critical factors in multimodal pertaining, including the scale of visual encoder, variants of attention mask, the most impactful parameters in VLMs, and the necessity of incorporating selfsupervised image loss, etc.   
+• We have made the weights of $\mathrm { C o g V L M }$ and the dataset used in the SFT phase available to the public. We anticipate that the open sourcing of CogVLM will significantly contribute to the research and industrial application of visual understanding.

+
+# 2 Method
+
+# 2.1 Architecture
+
+$\mathrm { C o g V L M }$ model comprises four fundamental components: a vision transformer (ViT) encoder, an MLP adapter, a pretrained large language model (GPT), and a visual expert module. Figure 3 shows an overview of the CogVLM architecture. The components’ design and implementation details are provided below:
+
+ViT encoder. We utilize pretrained EVA2-CLIP-E [Sun et al., 2023a] in CogVLM-17B. Note that the final layer of ViT encoder is removed because it specializes in aggregating the [CLS] features for contrastive learning.
+
+MLP adapter. To map the output of ViT into the same space as the text features from word embedding, we use an MLP adapter, a two-layer MLP (SwiGLU [Shazeer, 2020]). For implementation convenience, all image features share the same position id in the language model.
+
+Pretrained large language model. CogVLM’s model design is compatible with any off-the-shelf GPT-style pretrained large language model. Specifically, CogVLM-17B adopts Vicuna1.5-7B [Chiang et al., 2023] for further training. A causal mask is applied to all the attention operations, including the attention between image features.
+
+Visual expert module. We add a visual expert module to each layer to enable deep visual-language feature alignment. Specifically, the visual expert module in each layer consists of a QKV matrix and an MLP in each layer. The shapes of the QKV matrix and MLP are identical to those in the pretrained language model and initialized from them. The motivation is that each attention head in the language model captures a certain aspect of semantic information, while a trainable visual expert can transform the image features to align with the different heads, therefore enabling deep fusion.
+
+Formally, suppose that the input hidden states of an attention layer are $X \in \mathbb { R } ^ { B \times H \times ( L _ { I } + L _ { T } ) \times D }$ , where $B$ is the batch size, $L _ { I }$ and $L _ { T }$ are the lengths of image and text sequences, $H$ is the number of attention heads, and $D$ is the hidden size. In the attention with visual expert, $X$ is first split as image hidden states $X _ { I }$ and text hidden states $X _ { T }$ , and the attention is computed as:
+
+$$
+\operatorname { A t t e n t i o n } ( X , W _ { I } , W _ { T } ) = \operatorname { s o f t m a x } ( { \frac { \operatorname { T r i l } ( Q K ^ { T } ) } { \sqrt { D } } } ) V ,
+$$
+
+$$
+\begin{array} { r } { Q = \mathrm { c o n c a t } ( X _ { I } W _ { I } ^ { Q } , X _ { T } W _ { T } ^ { Q } ) , } \\ { K = \mathrm { c o n c a t } ( X _ { I } W _ { I } ^ { K } , X _ { T } W _ { T } ^ { K } ) , } \\ { V = \mathrm { c o n c a t } ( X _ { I } W _ { I } ^ { V } , X _ { T } W _ { T } ^ { V } ) , } \end{array}
+$$
+
+where $W _ { I } , W _ { T }$ are the QKV matrices of the visual expert and original language model, and $\operatorname { T r i l } ( \cdot )$ means lower-triangular mask. The visual expert in FFN layers performs similarly,
+
+$$
+\mathrm { F F N } ( X ) = \mathrm { c o n c a t } ( \mathrm { F F N } _ { I } ( X _ { I } ) , \mathrm { F F N } _ { T } ( X _ { T } ) ) ,
+$$
+
+where $\mathrm { F F N } _ { I }$ and $\mathrm { F F N } _ { T }$ are the FFN of the visual expert and original language model.
+
+Position embedding. In the RoPE within LLM, we allow all visual tokens to share a single position id, as they already encapsulate positional information when inputted into the ViT. This approach mitigates the impact of remote attenuation between tokens in the LLM. Given that an image can occupy hundreds to thousands of tokens, and a typical input sequence is structured as ‘<image embed $>$ query’, using conventional positional encoding would result in excessively lengthy encoding sequences. Moreover, it would lead the query to focus more on the image sequences closer to it, namely the lower part of an image.
+
+# 2.2 Pretraining
+
+Data. The image-text pairs for pretraining are all publicly available, including LAION-2B and COYO-700M. After removing the broken URLs, NSFW images, images with noisy captions, images with political bias and images with an aspect ratio $> 6$ or $\mathit { \Delta } < 1 / 6$ , about 1.5B images are left for pretraining.
+
+We also crafted a visual grounding dataset of 40M images. Each noun in the image caption is associated with bounding boxes to indicate the positions in the image. The construction process basically follows [Peng et al.], which extracts nouns via spaCy [Honnibal and Johnson, 2015] and predicts the bounding boxes using GLIPv2 [Zhang et al., 2022]. The image-text pairs are sampled from LAION-115M, a subset of LAION-400M filtered by [Li et al., 2023b]. We filter and retain a subset of 40 million images to ensure that over $7 5 \%$ of images contain at least two bounding boxes.
+
+Training. The first stage of pretraining is for image captioning loss, i.e. next token prediction in the text part. We train the CogVLM-17B model on the 1.5B image-text pairs introduced above for 120,000 iterations with a batch size of 8,192. The second stage of pretraining is a mixture of image captioning and Referring Expression Comprehension (REC). REC is a task to predict the bounding box in the image given the text description of an object, which is trained in the form of VQA, i.e., Question: Where is the object? and Answer: $[ [ x _ { 0 } , y _ { 0 } , x _ { 1 } , y _ { 1 } ] ]$ . Both $x$ and $y$ coordinates range from 000 to 999, meaning the normalized position in the image. We only consider the loss of the next token prediction in the “Answer” part. We pretrain the second stage for 60,000 iterations with a batch size of 1,024 on the text-image pairs and visual grounding datasets introduced above. During the final 30,000 iterations, we change the input resolution from $2 2 4 \times 2 2 4$ to $4 9 0 \times 4 9 0$ . The total number of trainable parameters is 6.5B.
+
+# 2.3 Alignment
+
+In the instruction alignment phase, we trained two generalist models: CogVLM-Chat and CogVLMGrounding. CogVLM-Chat accepts natural language inputs and outputs, while CogVLM-Grounding accepts inputs and outputs with bounding boxes.
+
+CogVLM-Chat. In our study, we integrated data from a variety of open-source visual questionanswering datasets, including VQAv2 [Antol et al., 2015], OKVQA [Marino et al., 2019], TextVQA [Singh et al., 2019], OCRVQA [Mishra et al., 2019], ScienceQA [Lu et al., 2022], as well as datasets formatted as multi-turn dialogues such as LLaVA-Instruct [Liu et al., 2023c], LRV-Instruction [Liu et al., 2023a], LLaVAR [Zhang et al., 2023b]. We then conducted unified instruction-supervised fine-tuning (SFT) across these diverse datasets. The integrity and quality of SFT data are crucial; notably, the LLaVA-Instruct dataset, initially generated through a language-only GPT-4 pipeline, contained certain inaccuracies. We meticulously corrected these errors through manual inspection and annotation to ensure data quality.
+
+VQA datasets typically feature concise, often one-word answers, contrasting with the dialogue datasets that provide detailed responses with extensive reasoning.

+
+During training, the model underwent 6000 iterations with a learning rate of 1e-5 and a batch size of 1024. To enhance and ensure the stability of the training, we activated the visual encoder’s parameters and adjusted its learning rate to be one-tenth of that used for the remaining training parameters.
+
+CogVLM-Grounding. In order to endow our model with consistent, interactive visual grounding capabilities, we collect a high-quality dataset covering 4 types of grounding data: (1) Grounded Captioning (GC) - image captioning datasets where each noun phrase within the caption is followed by the corresponding referential bounding boxes; (2) Referring Expression Generation (REG) - image-oriented datasets that each bounding box in the image is annotated with a descriptive textual expression that accurately characterizes and refers to the content within the specific region; (3) Referring Expression Comprehension (REC) - text-oriented datasets that each textual description is annotated with multiple referential links associating the phrases with corresponding boxes; (4) Grounded Visual Question Answering (GroundedVQA) - VQA-style datasets where the questions may contain region references in a given image. The sources of grounding data are all publicly available, including Flickr30K Entities [Plummer et al., 2015], RefCOCO [Kazemzadeh et al., 2014, Mao et al., 2016, Yu et al., 2016], Visual7W [Zhu et al., 2016], VisualGenome [Krishna et al., 2017] and Grounded CoT-VQA [Chen et al., 2023a]. [box] in this section is in the format of $[ [ x _ { 0 } , y _ { 0 } , x _ { 1 } , y _ { 1 } ] ]$ . It is noteworthy that the curated datasets exhibit a versatility of visual grounding capabilities, and many datasets can be adapted and repurposed across different tasks. For instance, grounded captioning datasets can be reformulated to suit REG and REC tasks. Taking the example of $^ { * } A$ man $\left[ b o x _ { 1 } \right]$ and a woman $[ b o x _ { 2 } ]$ are walking together.”, this can be reframed into question answering pairs like (“Describe this region $\left[ b o x _ { 2 } \right]$ .”, $^ { * } A$ woman.”) and (“Where is the man?”, “ $\left[ b o x _ { 1 } \right] ^ { \prime \prime } )$ . Similarly, REC datasets can be translated into REG tasks by switching the input and output, and vice versa. However, certain conversions might lead to ambiguities. For example, when presented with the isolated query “Where is another man?” from the caption “A man $\left[ b o x _ { 1 } \right]$ is running, while another man $\left[ b o x _ { 2 } \right]$ is looking.”, the distinction between $[ b o x _ { 1 } ]$ and $[ b o x _ { 2 } ]$ becomes unclear, potentially leading to errors.

+# 3 Experiments
+
+To rigorously validate the superior performance and robust generalization of our base model, we conduct quantitative evaluations on an array of multi-modal benchmarks. These benchmarks can be categorized into three broad areas covering a comprehensive range of measurement1:
+
+• Image Captioning. The main purpose of these tasks is to generate textual captions summarizing the major content of a given image. We utilize prominent datasets including

+
+NoCaps [Agrawal et al., 2019], COCO [Lin et al., 2014], Flickr30K [Plummer et al., 2015], and TextCaps [Sidorov et al., 2020] for evaluation.
+
+• Visual Question Answering. The VQA tasks require models to answer questions that may focus on distinct visual contents based on the given image. Our assessment covers diverse datasets, including VQAv2 [Antol et al., 2015], OKVQA [Marino et al., 2019] and ScienceQA [Lu et al., 2022].
+
+• LVLM Benchmarks. LVLM benchmarks are primarily employed to assess the advanced capabilities of large multimodal models, such as object recognition and localization, OCR, visual description, and visual knowledge reasoning. We conduct multidimensional evaluations of the models on datasets including MM-Vet [Yu et al., 2023], MMBench [Liu et al., $2 0 2 3 \mathrm { g } ]$ , SEED-Bench [Li et al., 2023a], LLaVA-Bench [Liu et al., 2023c], POPE [Li et al., 2023c], MMMU [Yue et al., 2023] and MathVista [Lu et al., 2023].
+
+• Visual Grounding. Visual grounding involves a set of tasks that establish referential links between textual mentions in a sentence and specific regions in an image. We evaluate our model on the typical datasets, including Visual7w [Zhu et al., 2016], RefCOCO [Liu et al., 2017], RefCOCO $^ +$ , and RefCOCOg to ensure completeness.
+
+# 3.1 Image Captioning
+
+We evaluate the image captioning capability of our pretrained base model on the aforementioned four benchmarks. In a zero-shot evaluation on the Nocaps and Flickr datasets, we assess the precision of our model in describing long-tail visual concepts. Additionally, we present results from finetuning on the COCO and TextCaps datasets.
+
+The detailed performance is shown in Table 1. Overall, our model achieves the SOTA or compatible performance across the board. Specifically, on the NoCaps benchmark, our base model outperforms the previous best method, GIT2, across four splits with a maximum of 5.7 points in the out-domain set while only consuming $10 \%$ of the pretraining data (1.5B vs 12.9B). On the Flickr benchmark, our model achieves a SOTA score of 94.9 surpassing the concurrently released Qwen-VL model by 9.1 points. These results demonstrate the remarkable capability and robustness of our pretrained model on the image captioning task. We also evaluate our model on the COCO [Lin et al., 2014] and TextCaps, where the latter is specifically designed to integrate the textual information of the given image into captions. Though training without the dedicated OCR data, encouragingly, our base model reveals a significant text-reading ability and obtains a competitive performance with PaLI-X-55B, and outperforms the previous best model of the same scale, PaLI-17B, by 9.1 points score.

+
+# 3.2 Visual Question Answering
+
+As illustrated in Table 2, our $\mathrm { C o g V L M }$ model demonstrates outstanding performance and a significant lead over models of similar parameter scale across a variety of tasks, including daily-life image question-answering dataset VQAv2, text-intensive image question-answering datasets such as TextVQA, and knowledge-demanding datasets like OKVQA and ScienceQA. This success showcases the model’s robust generalization capabilities and potential across diverse domains.
+
+# 3.3 LVLM Benchmarks
+
+Our findings, detailed in Table 2, demonstrate that $\mathrm { C o g V L M }$ achieved state-of-the-art results in all 7 LVLM-benchmarks, markedly surpassing all other models. It also outperformed multimodal models that utilized larger language models, such as LLava1.5 with Vicuna-13B and Emu-2 with LLAMA33B, leading by 15.7 and 2.6 points on MM-vet, 9.9 and 14.0 points on MMBench, respectively. Compared to IDEFICS-Instruct trained on LLaMA-65B, CogVLM’s scores exceeded by 19.3, 23.1, and 20.9 points on Seed-Bench, MMBench, and LLaVA-Bench, respectively. Furthermore, CogVLM achieved a score of 41.1 on the MMMU dataset, and also scored 87.9 on the hallucination assessment dataset POPE, along with 35.2 on the multimodal mathematical reasoning benchmark MathVista. These impressive results not only showcase its robust reasoning abilities and multi-task generalization capabilities but also clearly demonstrate that $\mathrm { C o g V L M }$ is significantly outpacing other models in these domains. Notably, shallow fusion models such as InstructBLIP and MiniGPT-4 underperformed across most benchmarks, despite InstructBLIP’s extensive training on instructional data, underscoring the necessity of deep fusion for enhanced performance.
+
+After using a stronger and larger LLaMA-3 language model as the backbone, our model achieved significant improvements on all benchmarks, fully demonstrating the robustness of our proposed method. The experimental results using other language models as backbones can be found in Appendix C.

+
+# 3.4 Visual Grounding
+
+Table 3 shows the result on the standard visual grounding benchmarks. We find that our generalist model achieves state-of-the-art performance across the board, with a significant advantage over the previous or concurrent models. As shown in the bottom part of Table 3, our model even surpasses models that are specifically trained for individual tasks, achieving SOTA performance on 5 of 9 splits. For instance, in the RefCOCO val subset, our model attains a score of 92.76, surpassing UNINEXTH’s 92.64; in the $\operatorname { R e f C O C O + }$ test-A subset, it scores 92.91, exceeding ONE-PEACE’s 92.21; and in the RefCOCOg test subset, it achieves 90.79, outperforming UNINEXT-H’s 89.27. These results suggest a remarkable visual grounding capability of our model incorporating our training paradigm.
+
+# 3.5 Ablation Study
+
+To understand the impact of various components and settings on our model’s performance, we conduct an extensive ablation study for 6,000 iterations and a batch size of 8,192. Table 4 summarizes the results about the following aspects:
+
+Model structure and tuned parameters. To investigate the effectiveness of $\mathrm { C o g V L M }$ ’s model, we conduct ablation studies on several structure variants and tuning strategies, including: 1) tuning only the MLP Adapter layer; 2) tuning all LLM parameters and the Adapter without adding visual expert; 3) only adding visual expert at every 4th LLM layer; and 4) only add visual expert to FFNs at all layers.
+
+From the results, we can see that shallow vision-language alignment, i.e. only tuning the adapter layer (similar to the method used in BLIP-2), results in a significantly inferior performance. Also, the performance of training the visual expert is higher than that of training the LLM, especially on the datasets that require external knowledge, even though the training parameters are roughly the same. We also compare with other variants of adding visual expert, including a. inserting an expert module every 4 layers and b. removing the attention part from the expert. Both of them result in a certain degree of performance decline, but within an acceptable range, which provides some guidance for balancing computational overhead and model performance.
+
+Initialization Method. As for visual expert’s initialization method, we compare initialization with weights from LLM to random initialization. Our results across various datasets demonstrate that initialization with LLM’s weights consistently achieves superior performance. This indicates that the transformer architecture pre-trained on language data possesses a certain capability to process visual tokens. Moreover, it can serve as a more effective starting point for multimodal pre-training initialization.
+
+Visual Attention Mask. We empirically find that using a causal mask on visual tokens yields a better result in comparison with a full mask. This is slightly counterintuitive, as using a bidirectional attention mask allows access to more information than a causal mask. We hypothesize the possible explanation for this phenomenon is that the causal mask better fits the inherent structure of LLMs.
+
+Image SSL Loss. We also investigated the self-supervised learning loss on image features, where each visual feature predicts the CLIP feature of the next position for visual self-supervision. Align with the observation from PaLI-X [Chen et al., 2023b], we find it brings no improvement on downstream tasks, although we indeed observed improvements in small models in our early experiments.
+
+Visual Encoder. we substituted the 300M-parameter EVA2-L model for the 4.4B-parameter EVA2-E to investigate the impact of visual encoder parameters on various tasks. The results indicated that there was only a slight decrease in performance across most benchmarks. However, a notable exception was observed in the text-oriented dataset TextVQA, where we recorded a decline of 2.5.
+
+EMA. We utilize EMA (Exponential Moving Average) during pretraining. The ablation results show that EMA often brings improvements across various tasks compared to not using it.
+
+# 4 Conclusion
+
+In this paper, we introduce $\mathrm { C o g V L M }$ , an open visual language foundation model. CogVLM shifts the paradigm for VLM training from shallow alignment to deep fusion, achieving state-of-the-art performance on 15 classic multi-modal benchmarks.
+
+The VLM training is still in its infancy, and there are many directions to explore, for example, better SFT alignment, RLHF and anti-hallucination. Since the previous famous VLMs are mostly closed-source, we believe $\mathrm { C o g V L M }$ will be a solid foundation for future multi-modal research.

+# A.2.1 Image Captioning
+
+• COCO [Lin et al., 2014] The Captions in COCO dataset are collected using Amazon’s Mechanical Turk (AMT) workers who are given instructions to control the quality. The dataset contains 330K images, where the train, validation and test sets contain 413,915 captions for 82,783 images, 202,520 captions for 40,504 images, and 379,249 captions for 40,775 images respectively.   
+NoCaps [Agrawal et al., 2019]. NoCaps is a large-scale benchmark for novel object captioning, containing nearly 400 novel object classes compared to COCO. The validation and test set comprised of 4,500 and 10,600 images, respectively, sourced from the Open Images [Krasin et al., 2017] and annotated with 11 human-generated captions per image, and each set is subdivided into three domains: “in", “near", and “out", with objects in the “out-domain" never appearing in the COCO dataset.   
+Flickr30K [Plummer et al., 2015]. Flickr30K is a high-quality dataset consists of 31,783 images of everyday life activities, envets and scenes (all harvested from the online website Flickr) and 158,915 captions (obtained via crodsourcing). Each image in this dataset is described independently by five annotators who are not familiar with the specific entities and circumstances depicted in them.   
+TextCaps [Sidorov et al., 2020] Textcaps is a dataset with $1 4 5 \mathrm { k }$ captions for $2 8 \mathrm { k }$ images. The design purpose of the TextCaps dataset is to effectively integrate textual information with visual context into captions, requiring the model to have both excellent OCR capabilities and strong captioning abilities.
+
+# A.2.2 General VQA
+
+• VQAv2 [Antol et al., 2015] VQAv2 encompasses over 200,000 images, paired with more than 1.1 million questions that have collectively garnered over 11 million answers. Questions span various types, including yes/no, counting, and open-ended queries.   
+OKVQA [Marino et al., 2019] The OK-VQA (Outside Knowledge Visual Question Answering) dataset is specifically designed to probe visual question answering capabilities that necessitate external knowledge or common sense beyond image content. It has 14,055 open-ended questions and 5 ground truth answers per question.   
+ScienceQA [Lu et al., 2022] The ScienceQA dataset comprises 21,208 multimodal multiplechoice questions spanning three diverse subjects: natural science, language science, and social science. Each question is annotated with explanations linked to relevant lectures. TDIUC [Shrestha et al., 2019] The TDIUC dataset features 1.6M questions across 170K images from MS COCO and Visual Genome. Categorized into 12 distinct question types, it ranges from basic tasks like identifying objects or colors to more advanced reasoning like counting or positional discernment.
+
+# A.3 LVLM Benchmarks
+
+• MM-Vet [Yu et al., 2023] MM-Vet defines six core VL capabilities and examines 16 integrations of interest derived from the combinations of these capabilities. It employs an evaluator based on LLMs for open-ended outputs, capable of assessing across different question types and answer styles, thus deriving a unified scoring metric.
+
+• SEED-Bench [Li et al., 2023a] SEED-Bench is a dataset comprising 19K multiple-choice questions with precise human annotations, covering 12 evaluation dimensions, including understanding of image and video modalities. It obtains accurate answer options through manual annotations, enabling objective and efficient assessment of model performance.
+
+• MMBench [Liu et al., $2 0 2 3 \mathrm { g } ]$ MMBench comprises approximately 3000 multiple-choice questions, covering 20 different capability dimensions, aimed at evaluating various abilities of visual-language models. MMBench adopts a hierarchical capability dimension structure, including two high-level capability dimensions: perception and reasoning, as well as finegrained capability dimensions such as object localization and attribute inference.
+
+• LLaVA-Bench [Liu et al., 2023c] LLaVA-Bench (In-the-Wild) is a benchmark dataset comprising 60 questions, designed to evaluate the multimodal instruction following capabilities of LMMs. It includes indoor and outdoor scenes, memes, paintings, sketches, etc., and is equipped with highly detailed, manually curated descriptions and appropriate question selections.
+
+• POPE [Li et al., 2023c] The POPE dataset is a binary classification query dataset specifically designed to evaluate object hallucination issues in LMMs. The random, popular, and adversarial subsets within the POPE dataset are constructed through different sampling strategies, totaling 8,910 entries.
+
+• MMMU [Yue et al., 2023] The MMMU dataset is a large-scale, multidisciplinary multimodal understanding and reasoning benchmark set, containing 11.5K questions. It covers 6 major disciplines, 30 topics, and 183 subfields, with question types including multiple-choice and open-ended questions. The dataset includes 30 types of images, such as charts, tables, chemical structures, photographs, paintings, musical scores, etc., testing the multimodal perception capabilities of models and their performance in expert-level tasks.
+
+• MathVista [Lu et al., 2023] MathVista is a new benchmark dataset that combines mathematical and visual understanding, comprising 31 existing multimodal datasets and 3 newly created datasets, totaling 6141 examples. These datasets encompass a diverse range of mathematical reasoning abilities, including seven types: algebra, arithmetic, geometry, logic, numerical common sense, science, and statistics. The goal is to comprehensively evaluate the capabilities of existing foundational models in mathematical reasoning and visual understanding.
+
+# A.3.1 Grounding
+
+• RefCOCO/RefCOCO $^ +$ [Liu et al., 2017] RefCOCO and $\operatorname { R e f C O C O + }$ evolved from the ReferItGame. Both subsets focus on images with two or more similar objects. RefCOCO, with 142,209 expressions across 19,994 images, places no linguistic constraints. Conversely, RefCOCO $^ +$ emphasizes appearance-centric descriptions, omitting locational terms, and comprises 141,564 expressions over 19,992 images.
+
+• RefCOCOg [Mao et al., 2016] The RefCOCOg subset was amassed through Amazon Mechanical Turk, where workers penned natural referring expressions for objects in MSCOCO images; it boasts 85,474 referring expressions spanning 26,711 images, each containing 2 to 4 objects of the same category.
+
+• Visual7W [Zhu et al., 2016]. The Visual7W dataset is predominantly designed for VQA tasks, with a dedicated subset crafted for grounded VQA. In this subset, models are presented with an image accompanied by a “which"-type question, such as “Which is the small computer in the corner?". Participants are then given four bounding boxes within the image, from which they must select the correct one as the answer. The grounded Visual7W part consists of 25,733 images and 188,068 questions.
+
+• Flickr30K-Entities [Plummer et al., 2015]. The Flickr30K Entities dataset, a precursor in the realm of grounded captioning, encompasses a collection of 31,783 images accompanied by $1 5 8 \mathrm { k }$ captioning annotations. Every caption in this dataset has been meticulously annotated such that each noun phrase is linked with a manually delineated referential bounding box. In total, there are 276k such annotated bounding boxes provided within this dataset.
+
+• VisualGenome [Krishna et al., 2017]. The VisualGenome dataset stands as a cornerstone in understanding the multifaceted relationships present within images. With a collection of over $1 0 0 \mathrm { k }$ images, each image is annotated in detail, capturing an average of 21 objects, 18 attributes, and 18 inter-object relationships. A unique aspect of this dataset is the alignment of objects, attributes, relationships, and region descriptions with standardized terminologies from WordNet. Specifically tailored for the REG and REC tasks, each annotated region in an image comes with a corresponding descriptive text, making it a rich resource for image understanding and semantic modeling. We use the subset with around 86k images and 3.6 million region-caption pairs for visual grounding.

+Figure 4: Performance on TDIUC benchmark with fine-grained questions classes.
+
+# B Additional Fine-grained Experiments
+
+To comprehensively investigate the proposed model on specific topics and question types, we further conduct extensive experiments on a representative benchmark, TDIUC [Kafle and Kanan, 2017]. We use the publicly available split of val set as evaluation data, and the VQA accuracy calculated from their official scripts as the evaluation metric.
+
+The experimental results on TDIUC compare our model against the specialist SOTA method MUREL [Cadene et al., 2019] are shown in Figure 4. From the experimental result, we can see that our model consistently outperforms the previous model on 12 specific question types, resulting in a 94.0 accuracy score compared to the previous SOTA of 88.2 on the overall dataset. These results demonstrate that our model exhibits comprehensive problem-solving skills on general VQA tasks.

+
+As shown in the Table 8, our visual expert module is integrated into the LLM, and it can significantly benefit from the scaling of the LLM. These results demonstrate that our approach can effectively leverage the benefits of LLM scaling to improve performance on multimodal tasks.
+
+# D Computational Efficiency
+
+In this section, we compare the computational efficiency of our model with other state-of-the-art models, considering both pretraining and finetuning data from datasets such as VQAv2 and TextVQA. Owing to an optimized architecture and the utilization of high-quality pretraining data, our model demonstrates a marked reduction in resource consumption during training relative to models with comparable parameter magnitudes.

+
+# NeurIPS Paper Checklist
+
+# 1. Claims
+
+Question: Do the main claims made in the abstract and introduction accurately reflect the paper’s contributions and scope?
+
+Answer: [Yes]
+
+Justification: The abstract and introduction of this paper accurately reflect the contributions and scope of the research.
+
+Guidelines:
+
+• The answer NA means that the abstract and introduction do not include the claims made in the paper.   
+• The abstract and/or introduction should clearly state the claims made, including the contributions made in the paper and important assumptions and limitations. A No or NA answer to this question will not be perceived well by the reviewers.   
+• The claims made should match theoretical and experimental results, and reflect how much the results can be expected to generalize to other settings.   
+• It is fine to include aspirational goals as motivation as long as it is clear that these goals are not attained by the paper.
+
+# 2. Limitations
+
+Question: Does the paper discuss the limitations of the work performed by the authors?
+
+Answer: [NA]
+
+Justification: The paper has no limitation.
+
+Guidelines:
+
+• The answer NA means that the paper has no limitation while the answer No means that the paper has limitations, but those are not discussed in the paper.   
+• The authors are encouraged to create a separate "Limitations" section in their paper.   
+• The paper should point out any strong assumptions and how robust the results are to violations of these assumptions (e.g., independence assumptions, noiseless settings, model well-specification, asymptotic approximations only holding locally). The authors should reflect on how these assumptions might be violated in practice and what the implications would be.   
+The authors should reflect on the scope of the claims made, e.g., if the approach was only tested on a few datasets or with a few runs. In general, empirical results often depend on implicit assumptions, which should be articulated.   
+• The authors should reflect on the factors that influence the performance of the approach. For example, a facial recognition algorithm may perform poorly when image resolution is low or images are taken in low lighting. Or a speech-to-text system might not be used reliably to provide closed captions for online lectures because it fails to handle technical jargon.   
+• The authors should discuss the computational efficiency of the proposed algorithms and how they scale with dataset size.   
+• If applicable, the authors should discuss possible limitations of their approach to address problems of privacy and fairness.   
+• While the authors might fear that complete honesty about limitations might be used by reviewers as grounds for rejection, a worse outcome might be that reviewers discover limitations that aren’t acknowledged in the paper. The authors should use their best judgment and recognize that individual actions in favor of transparency play an important role in developing norms that preserve the integrity of the community. Reviewers will be specifically instructed to not penalize honesty concerning limitations.
+
+# 3. Theory Assumptions and Proofs
+
+Question: For each theoretical result, does the paper provide the full set of assumptions and a complete (and correct) proof?
+
+Answer: [NA]
+
+Justification: The paper does not include theoretical results.
+
+Guidelines:
+
+• The answer NA means that the paper does not include theoretical results.   
+• All the theorems, formulas, and proofs in the paper should be numbered and crossreferenced.   
+• All assumptions should be clearly stated or referenced in the statement of any theorems.   
+• The proofs can either appear in the main paper or the supplemental material, but if they appear in the supplemental material, the authors are encouraged to provide a short proof sketch to provide intuition.   
+Inversely, any informal proof provided in the core of the paper should be complemented by formal proofs provided in appendix or supplemental material.   
+• Theorems and Lemmas that the proof relies upon should be properly referenced.
+
+# 4. Experimental Result Reproducibility
+
+Question: Does the paper fully disclose all the information needed to reproduce the main experimental results of the paper to the extent that it affects the main claims and/or conclusions of the paper (regardless of whether the code and data are provided or not)?
+
+Answer: [Yes]
+
+Justification: The paper fully discloses all the information needed to reproduce the main experimental results, including training details, training parameters, and model weights, which have been made open-source.
+
+Guidelines:
+
+• The answer NA means that the paper does not include experiments.   
+• If the paper includes experiments, a No answer to this question will not be perceived well by the reviewers: Making the paper reproducible is important, regardless of whether the code and data are provided or not.   
+• If the contribution is a dataset and/or model, the authors should describe the steps taken to make their results reproducible or verifiable.   
+Depending on the contribution, reproducibility can be accomplished in various ways. For example, if the contribution is a novel architecture, describing the architecture fully might suffice, or if the contribution is a specific model and empirical evaluation, it may be necessary to either make it possible for others to replicate the model with the same dataset, or provide access to the model. In general. releasing code and data is often one good way to accomplish this, but reproducibility can also be provided via detailed instructions for how to replicate the results, access to a hosted model (e.g., in the case of a large language model), releasing of a model checkpoint, or other means that are appropriate to the research performed.   
+While NeurIPS does not require releasing code, the conference does require all submissions to provide some reasonable avenue for reproducibility, which may depend on the nature of the contribution. For example (a) If the contribution is primarily a new algorithm, the paper should make it clear how to reproduce that algorithm. (b) If the contribution is primarily a new model architecture, the paper should describe the architecture clearly and fully. (c) If the contribution is a new model (e.g., a large language model), then there should either be a way to access this model for reproducing the results or a way to reproduce the model (e.g., with an open-source dataset or instructions for how to construct the dataset). (d) We recognize that reproducibility may be tricky in some cases, in which case authors are welcome to describe the particular way they provide for reproducibility. In the case of closed-source models, it may be that access to the model is limited in some way (e.g., to registered users), but it should be possible for other researchers to have some path to reproducing or verifying the results.
+
+# 5. Open access to data and code
+
+Question: Does the paper provide open access to the data and code, with sufficient instructions to faithfully reproduce the main experimental results, as described in supplemental material?
+
+Answer: [Yes]
+
+Justification: The paper provides open access to the dataset used in the instruction fine-tuning phase and the training code, along with sufficient instructions to faithfully reproduce the main experimental results.
+
+Guidelines:
+
+• The answer NA means that paper does not include experiments requiring code.   
+• Please see the NeurIPS code and data submission guidelines (https://nips.cc/ public/guides/CodeSubmissionPolicy) for more details.   
+• While we encourage the release of code and data, we understand that this might not be possible, so “No” is an acceptable answer. Papers cannot be rejected simply for not including code, unless this is central to the contribution (e.g., for a new open-source benchmark).   
+• The instructions should contain the exact command and environment needed to run to reproduce the results. See the NeurIPS code and data submission guidelines (https: //nips.cc/public/guides/CodeSubmissionPolicy) for more details.   
+• The authors should provide instructions on data access and preparation, including how to access the raw data, preprocessed data, intermediate data, and generated data, etc.   
+• The authors should provide scripts to reproduce all experimental results for the new proposed method and baselines. If only a subset of experiments are reproducible, they should state which ones are omitted from the script and why.   
+• At submission time, to preserve anonymity, the authors should release anonymized versions (if applicable).   
+• Providing as much information as possible in supplemental material (appended to the paper) is recommended, but including URLs to data and code is permitted.
+
+# 6. Experimental Setting/Details
+
+Question: Does the paper specify all the training and test details (e.g., data splits, hyperparameters, how they were chosen, type of optimizer, etc.) necessary to understand the results?
+
+Answer: [Yes]
+
+Justification: The paper specifies all the training and test details, including data splits, hyperparameters, their selection process, the type of optimizer, etc., either in the main text or in the appendix, providing a comprehensive understanding of the results.
+
+Guidelines:
+
+• The answer NA means that the paper does not include experiments. • The experimental setting should be presented in the core of the paper to a level of detail that is necessary to appreciate the results and make sense of them. • The full details can be provided either with the code, in appendix, or as supplemental material.
+
+# 7. Experiment Statistical Significance
+
+Question: Does the paper report error bars suitably and correctly defined or other appropriate information about the statistical significance of the experiments?
+
+Answer: [No]
+
+Justification: The paper does not report error bars or other statistical significance information because the experimental results are distinct enough to be interpreted without them.
+
+Guidelines:
+
+• The answer NA means that the paper does not include experiments. • The authors should answer "Yes" if the results are accompanied by error bars, confidence intervals, or statistical significance tests, at least for the experiments that support the main claims of the paper.
+
+• The factors of variability that the error bars are capturing should be clearly stated (for example, train/test split, initialization, random drawing of some parameter, or overall run with given experimental conditions).   
+• The method for calculating the error bars should be explained (closed form formula, call to a library function, bootstrap, etc.)   
+• The assumptions made should be given (e.g., Normally distributed errors).   
+• It should be clear whether the error bar is the standard deviation or the standard error of the mean.   
+• It is OK to report 1-sigma error bars, but one should state it. The authors should preferably report a 2-sigma error bar than state that they have a $96 \%$ CI, if the hypothesis of Normality of errors is not verified.   
+• For asymmetric distributions, the authors should be careful not to show in tables or figures symmetric error bars that would yield results that are out of range (e.g. negative error rates).   
+• If error bars are reported in tables or plots, The authors should explain in the text how they were calculated and reference the corresponding figures or tables in the text.
+
+# 8. Experiments Compute Resources
+
+Question: For each experiment, does the paper provide sufficient information on the computer resources (type of compute workers, memory, time of execution) needed to reproduce the experiments?
+
+Answer: [Yes]
+
+Justification: The paper provides sufficient information on the computer resources required to reproduce each experiment, including the type of compute workers, memory, and time of execution, in both the main text and the appendix.
+
+Guidelines:
+
+• The answer NA means that the paper does not include experiments.   
+• The paper should indicate the type of compute workers CPU or GPU, internal cluster, or cloud provider, including relevant memory and storage.   
+• The paper should provide the amount of compute required for each of the individual experimental runs as well as estimate the total compute.   
+• The paper should disclose whether the full research project required more compute than the experiments reported in the paper (e.g., preliminary or failed experiments that didn’t make it into the paper).
+
+# 9. Code Of Ethics
+
+Question: Does the research conducted in the paper conform, in every respect, with the NeurIPS Code of Ethics https://neurips.cc/public/EthicsGuidelines?
+
+Answer: [Yes]
+
+Justification: Justification: The research conducted in the paper fully conforms with the NeurIPS Code of Ethics.
+
+Guidelines:
+
+• The answer NA means that the authors have not reviewed the NeurIPS Code of Ethics.   
+• If the authors answer No, they should explain the special circumstances that require a deviation from the Code of Ethics.   
+• The authors should make sure to preserve anonymity (e.g., if there is a special consideration due to laws or regulations in their jurisdiction).
+
+# 10. Broader Impacts
+
+Question: Does the paper discuss both potential positive societal impacts and negative societal impacts of the work performed?
+
+Answer: [NA]
+
+Justification: There is no societal impact of the work performed.
+
+Guidelines:
+
+• The answer NA means that there is no societal impact of the work performed.   
+• If the authors answer NA or No, they should explain why their work has no societal impact or why the paper does not address societal impact.   
+• Examples of negative societal impacts include potential malicious or unintended uses (e.g., disinformation, generating fake profiles, surveillance), fairness considerations (e.g., deployment of technologies that could make decisions that unfairly impact specific groups), privacy considerations, and security considerations.   
+• The conference expects that many papers will be foundational research and not tied to particular applications, let alone deployments. However, if there is a direct path to any negative applications, the authors should point it out. For example, it is legitimate to point out that an improvement in the quality of generative models could be used to generate deepfakes for disinformation. On the other hand, it is not needed to point out that a generic algorithm for optimizing neural networks could enable people to train models that generate Deepfakes faster. The authors should consider possible harms that could arise when the technology is being used as intended and functioning correctly, harms that could arise when the technology is being used as intended but gives incorrect results, and harms following from (intentional or unintentional) misuse of the technology.   
+• If there are negative societal impacts, the authors could also discuss possible mitigation strategies (e.g., gated release of models, providing defenses in addition to attacks, mechanisms for monitoring misuse, mechanisms to monitor how a system learns from feedback over time, improving the efficiency and accessibility of ML).
+
+# 11. Safeguards
+
+Question: Does the paper describe safeguards that have been put in place for responsible release of data or models that have a high risk for misuse (e.g., pretrained language models, image generators, or scraped datasets)?
+
+Answer: [NA]
+
+Justification: The paper poses no such risks.
+
+Guidelines:
+
+• The answer NA means that the paper poses no such risks.   
+• Released models that have a high risk for misuse or dual-use should be released with necessary safeguards to allow for controlled use of the model, for example by requiring that users adhere to usage guidelines or restrictions to access the model or implementing safety filters.   
+• Datasets that have been scraped from the Internet could pose safety risks. The authors should describe how they avoided releasing unsafe images.   
+• We recognize that providing effective safeguards is challenging, and many papers do not require this, but we encourage authors to take this into account and make a best faith effort.
+
+# 12. Licenses for existing assets
+
+Question: Are the creators or original owners of assets (e.g., code, data, models), used in the paper, properly credited and are the license and terms of use explicitly mentioned and properly respected?
+
+Answer: [Yes]
+
+Justification: The creators or original owners of assets such as code, data, and models used in the paper are properly credited, and the license and terms of use are explicitly mentioned and properly respected.
+
+Guidelines:
+
+• The answer NA means that the paper does not use existing assets.   
+• The authors should cite the original paper that produced the code package or dataset.   
+• The authors should state which version of the asset is used and, if possible, include a URL.   
+• The name of the license (e.g., CC-BY 4.0) should be included for each asset.   
+• For scraped data from a particular source (e.g., website), the copyright and terms of service of that source should be provided.   
+• If assets are released, the license, copyright information, and terms of use in the package should be provided. For popular datasets, paperswithcode.com/datasets has curated licenses for some datasets. Their licensing guide can help determine the license of a dataset.   
+• For existing datasets that are re-packaged, both the original license and the license of the derived asset (if it has changed) should be provided.   
+• If this information is not available online, the authors are encouraged to reach out to the asset’s creators.
+
+# 13. New Assets
+
+Question: Are new assets introduced in the paper well documented and is the documentation provided alongside the assets?
+
+Answer: [Yes]
+
+Justification: New assets introduced in the paper are well documented, and the documentation is provided alongside the assets.
+
+Guidelines:
+
+• The answer NA means that the paper does not release new assets.   
+• Researchers should communicate the details of the dataset/code/model as part of their submissions via structured templates. This includes details about training, license, limitations, etc.   
+• The paper should discuss whether and how consent was obtained from people whose asset is used.   
+• At submission time, remember to anonymize your assets (if applicable). You can either create an anonymized URL or include an anonymized zip file.
+
+# 14. Crowdsourcing and Research with Human Subjects
+
+Question: For crowdsourcing experiments and research with human subjects, does the paper include the full text of instructions given to participants and screenshots, if applicable, as well as details about compensation (if any)?
+
+Answer: [NA]
+
+Justification: The paper does not involve crowdsourcing nor research with human subjects.
+
+Guidelines:
+
+• The answer NA means that the paper does not involve crowdsourcing nor research with human subjects.   
+• Including this information in the supplemental material is fine, but if the main contribution of the paper involves human subjects, then as much detail as possible should be included in the main paper.   
+• According to the NeurIPS Code of Ethics, workers involved in data collection, curation, or other labor should be paid at least the minimum wage in the country of the data collector.
+

+# POINT-BIND & POINT-LLM: ALIGNING POINT CLOUD WITH MULTI-MODALITY FOR 3D UNDERSTANDING, GENERATION, AND INSTRUCTION FOLLOWING
+
+Anonymous authors Paper under double-blind review
+
+# ABSTRACT
+
+With the growing diversity of large-scale data, learning from multi-modality has attained notable progress in language and 2D vision. However, in 3D domains, how to develop an all-purpose multi-modal framework is still under-explored. To this end, we introduce Point-Bind, a 3D multi-modality model aligning point clouds with 2D image, language, audio, and video. Guided by ImageBind, we construct a joint embedding space between 3D and multi-modalities, enabling many promising applications, e.g., 3D embedding arithmetic, any-to-3D generation, and 3D open-world understanding. On top of this joint embedding space, we further present Point-LLM, a 3D large language model extending ImageBindLLM to follow 3D and multi-modal instructions. Without any 3D instruction data, our Point-LLM injects the semantics of Point-Bind into pre-trained LLMs, e.g., LLaMA, and exhibits superior 3D and multi-modal question-answering capacity. We have conducted extensive experiments to demonstrate the effectiveness and generalizability of our approach for aligning 3D and multi-modality.
+
+# 1 INTRODUCTION
+
+In these years, 3D vision has gained significant attention and development, driven by the rising popularity of autonomous driving (Chen et al., 2020b; Shi et al., 2020), navigation (Tan et al., 2001; Wang et al., 2019), 3D scene understanding (Armeni et al., 2016; Liu et al., 2021b), and robotics (Huang et al., 2023; Savva et al., 2019). To extend its application scenarios, numerous efforts have been made to incorporate 3D point clouds with other modalities, allowing for improved 3D understanding (Guo et al., 2023a; Afham et al., 2022), text-to-3D generation (Nichol et al., 2022; Poole et al., 2022), and 3D question answering (Azuma et al., 2022; Hong et al., 2023a).

+Figure 1: Overview of Point-Bind. We propose a unified and general framework to align 3D with multiple modalities.
+
+For 3D geometry understanding, previous works either leverage 2D-language embeddings to guide 3D open-world recognition (Zhang et al., 2022b), or harness visual and textual semantics to assist 3D representation learning (Xue et al., 2022). However, their perception capabilities are mostly constrained by limited modalities provided in the training phase. Inspired by 2D generative models, a collection of methods (Lin et al., 2023; Nichol et al., 2022) has achieved text-to-3D synthesis with high quality and efficiency. Despite this, they lack the ability to generate 3D shapes conditioned on multi-modal input, e.g., a sound and an image. Another series of works connects descriptive natural language with 3D data, applying to 3D captioning (Yuan et al., 2022; Chen et al., 2023b) and question answering (Wijmans et al., 2019; Azuma et al., 2022). Yet, they fail to utilize the pre-trained linguistic knowledge within large language models (LLMs) to better reason 3D geometries. Therefore, how to develop a unified 3D framework aligning with multi-modality for general 3D learning still remains an open question. Very recently, ImageBind (Girdhar et al., 2023) is proposed to learn a shared representation space across six different modalities, i.e., image, text, audio, depth, thermal, and IMU data. Motivated by this, we ask the following question: can we construct a joint embedding space between 3D and multi-modality for unified 3D understanding, generation, and instruction following?
+
+![](images/6ad6a5342357d7aa24f4035faa2fcdb3b353a9f16ce7b6a4f0efc2830e635b0e.jpg)  
+Figure 2: 3D Multi-modal Applications of Point-Bind. With a joint 3D multi-modal embedding space, Point-Bind enables many promising application scenarios, e.g., Point-LLM for 3D instruction following, 3D generation conditioned on any modalities, embedding-space arithmetic with 3D, and multi-modal 3D zero-shot understanding.
+
+In this paper, we introduce Point-Bind, a 3D multi-modality framework that aligns point cloud with multiple modalities for general 3D analysis, as shown in Figure 1. Specifically, we first collect 3D-image-text-audio pairs as the training data, and learn a joint embedding space guided by ImageBind, or other multi-modal large models (Zhu et al., 2023a). Based on the pre-training paragdim of previous works (Xue et al., 2022; Zeng et al., 2023), we adopt a contrastive loss between the extracted features from a trainable 3D encoder, e.g., I2P-MAE (Zhang et al., 2023a), and the pretrained multi-modal encoders. In this way, we efficiently integrate different modalities into a unified representation space, which also includes modalities that are absent during training, such as video, depth, and infrared data. The joint space of Point-Bind is expected to expand the scope of 3D models to wider cross-modal scenarios.
+
+On top of this, Point-Bind naturally motivates several emergent 3D-centric multi-modal applications, as shown in Figure 2. Note that, such emergent characteristics can alleviate the need for expensive task-specific training, significantly lowering the bar to efficiently achieve new 3D cross-modal tasks, summarized as follows:
+
+• 3D Embedding-space Arithmetic. We observe the encoded 3D features from Point-Bind can be added with other modalities to incorporate their semantics, achieving favorable composed cross-modal retrieval performance. • Any-to-3D Generation. Based on existing text-to-3D generative models, Point-Bind enables 3D shape synthesis conditioned on any input modalities and their composition, e.g., text/image/audio/point-to-mesh, or editing 3D shapes with multi-modal instructions. • 3D Open-world Understanding. Benefiting from multi-modal semantics, Point-Bind attains leading performance for 3D zero-shot classification, referred to by text. Also, our approach supports audio-referred 3D open-world understanding with satisfactory results.

+Figure 3: 3D Question-answering Examples of Point-LLM. Given 3D and multi-modal instructions, our Point-LLM can effectively generate detailed responses and conduct superior cross-modal reasoning. Notably, we do not need any 3D instruction data for training.
+
+Furthermore, with the joint embedding space, we propose to incorporate Point-Bind with the pretrained ImageBind-LLM (Han et al., 2023) to develop a 3D large language model, termed as PointLLM. As shown in Figure 3, our Point-LLM can respond to language instructions with 3D point cloud conditions, and effectively capture spatial geometry characteristics with bilingual competence. Referring to ImageBind-LLM, we connect our Point-Bind with its pre-trained bind network and visual cache model to bridge our 3D embedding space with LLaMA (Touvron et al., 2023). In such a training-free manner, our Point-LLM enables LLaMA to understand the 3D world with superior question-answering capacity, while requiring no 3D instruction data. Notably, our approach can generate descriptive responses conditioned on a combination of 3D and multi-modal input, e.g., a point cloud with an image/audio, indicating strong cross-modal reasoning capacity.

+The overall pipeline of Point-Bind is shown in Figure 4. In Section 2.1, we first provide a preliminary of ImageBind (Girdhar et al., 2023). Then, in Section 2.2 and 2.3, we elaborate on the training data and multi-modal alignment for Point-Bind, respectively. Finally, in Section 2.4, we introduce several 3D-centric applications derived from our approach.
+
+# 2.1 PRELIMINARY OF IMAGEBIND
+
+ImageBind proposes an approach to combine multiple modalities together, which utilizes only image-paired data to learn a joint embedding space of six modalities, i.e., images, text, audio, depth, thermal, and IMU data. It does not need training dataset pairing all six modalities, but leverages the binding property of 2D images, i.e., aligning every single modality to image independently. Specifically, ImageBind feeds multi-modal input into corresponding encoders, and adopts for cross-modal contrastive learning. After training on large-scale image-paired data, ImageBind effectively aligns six modalities into a single representation space, enabling emergent cross-modal capabilities.

+Figure 4: Overall Pipeline of Point-Bind. We collect 3D-image-audio-text data pairs for contrastive learning, which aligns 3D with other modalities guided ImageBind (Girdhar et al., 2023). With a joint embedding space, Point-Bind can be utilized for 3D cross-modal retrieval, any-to-3D generation, 3D zero-shot understanding, and developing a 3D large language model, Point-LLM.
+
+Inspired by this, we propose to develop a 3D multi-modal framework, Point-Bind, which leverages ImageBind, or its follow-up work (Zhu et al., 2023a), as guidance to incorporate 3D point cloud with other modalities for general 3D understanding, generation, and instruction following.
+
+# 2.2 TRAINING DATA
+
+To align 3D with multi-modalities, we leverage the pre-trained joint embedding space of ImageBind (Girdhar et al., 2023) and adopt contrastive loss (Zhang et al., 2022c; Radford et al., 2021) to simultaneously align 3D point clouds with the other three modalities: image, text, and audio. To obtain the contrastive training data, we collect a cross-modal dataset of 3D-image-audio-text pairs. There are three steps for dataset collection as follows.
+
+3D-image-text Pairs. We adopt the data pairs of 3D, images, and text from ULIP (Xue et al., 2022), which includes 3D-image-text triplets built from ShapeNet (Chang et al., 2015), a commonused dataset containing abundant 3D CAD models. Each 3D point cloud is paired with a corresponding text describing the semantic information of its spatial shape, and a 2D counterpart generated by multi-view image rendering. The text description is constructed by a synset of category names and 64 pre-defined templates.
+
+3D-audio Pairs. To provide more contrastive signals from a fourth modality, we collect the data pairs of 3D and audio from ESC-50 (Piczak, 2015) and ShapeNet datasets. Specifically, we first select the categories whose objects can make a sound in the real world from the 55 categories of ShapeNet, such as ‘airplane’, ‘clock’, ‘washing machine’, and ‘keyboard’. Then, we preserve only the categories that are also within ESC-50. By this standard, we obtain 9 categories of 3D point clouds paired with extensive audio clips, i.e., ‘airplane’, ‘chirping birds’, ‘can opening’, ‘car horn’, ‘clock tick’, ‘keyboard typing’, ‘crackling fire’, and ‘train’. Each category contains 40 audio samples, with a total number of 360. During training, for a point cloud within the nine categories, we randomly sample an audio sample and adopt data augmentation, e.g., random cropping and volume perturbation, for more robust training.
+
+3D-image-audio-text Pairs Construction. Finally, we match each 3D-audio pair with its corresponding 3D-image-text data, resulting in a unified 3D-image-audio-text dataset with extensive cross-modal pairs. During training, we simultaneously feed point clouds and their paired data of three modalities for contrastive learning.
+
+![](images/3ef7d700455e9bf3335a542bcf7d18398123a129ba96ec48fa9c1d409269cf9a.jpg)  
+Figure 5: Inference Paradigm of Point-LLM. Due to our 3D joint embedding space, we can directly connect Point-Bind with a pre-trained bind network of ImageBind-LLM (Han et al., 2023) to enable LLaMA (Touvron et al., 2023) to follow 3D instructions. Optionally, our Point-LLM can also take as input multi-modality data, and conduct cross-modal reasoning for language response.
+
+# 2.3 ALIGNING 3D WITH MULTI-MODALITY
+
+After collecting the 3D paired data, we conduct contrastive training to learn a joint embedding space aligning 3D and multi-modalities. Each data sample contains a point cloud $P$ , along with the paired 2D image $I$ , text description $T ^ { s }$ , and audio $A$ , where $T ^ { s }$ represents a set of 64 pre-defined templates. For the point cloud, we adopt I2P-MAE (Zhang et al., 2023a) as the learnable 3D encoder, denoted as $\mathrm { E n c o d e r _ { 3 D } ( \cdot ) }$ , and append a projection network $\mathrm { P r o j } ( \cdot )$ of two linear layers, which transforms the encoded 3D feature into ImageBind’s multi-modal embedding space. We formulate it as
+
+$$
+F _ { \mathrm { 3 } D } = \mathrm { P r o j } ( \mathrm { E n c o d e r } _ { \mathrm { 3 D } } ( P ) ) ,
+$$
+
+where $F _ { 3 D } \in \mathbb { R } ^ { 1 \times C }$ denotes the projected 3D embedding, and $C$ equals the feature dimension of ImageBind. For the paired image-text-audio data, we leverage their corresponding encoders from ImageBind for feature extraction, which are frozen during training, formulated as
+
+$$
+F _ { 2 D } , F _ { T } ^ { s } , F _ { A } = \mathrm { I m a g e B i n d } ( I , T ^ { s } , A ) ,
+$$
+
+where $F _ { 2 D } , F _ { A } \in \mathbb { R } ^ { 1 \times C }$ denote the image and audio embeddings, and $F _ { T } ^ { s } \in \mathbb { R } ^ { 6 4 \times C }$ denotes the text embedding for a set of 64 descriptions. Then, we conduct an average pooling as
+
+$$
+F _ { T } = \mathrm { A v e r a g e } ( F _ { T } ^ { s } ) \in \mathbb { R } ^ { 1 \times C } ,
+$$
+
+which represents the aggregated text embedding with more robustness. After that, we adopt contrastive loss (Zhang et al., 2022c) between 3D and other modalities, which effectively enforces 3D embeddings to align with the joint representation space, formulated as
+
+$$
+{ \cal L } _ { t o t a l } = { \cal L } ( F _ { 3 D } , F _ { 2 D } ) + { \cal L } ( F _ { 3 D } , F _ { T } ) + { \cal L } ( F _ { 3 D } , F _ { A } ) .
+$$
+
+Note that some training categories do not include the paired audio $A$ , since they inherently cannot make any sound, e.g., bottle, planter, and couch, for which we ignore their audio features and loss.
+
+# 2.4 MULTI-MODAL APPLICATIONS
+
+Starting from the joint embedding space of Point-Bind, we introduce several emergent application scenarios concerning 3D and multi-modalities. Importantly, these new tasks are naturally emergent from Point-Bind, which means we do not need to spend many resources on task-specific training. Such characteristics significantly lower the bar for efficiently achieving new 3D cross-modal tasks.
+
+3D Embedding-space Arithmetic. We observe that 3D features encoded by Point-Bind can be directly added with other modalities to incorporate their semantics, further achieving composed cross-modal retrieval. For instance, the combined embeddings of a 3D car and audio of sea waves can accurately retrieve an image showing a car parking by a beach, while the composition of a 3D laptop and audio of keyboard typing can retrieve an image of someone who is working with a laptop.

+
+Any-to-3D Generation. Existing 3D generation methods can only achieve text-to-3D synthesis. In contrast, with the joint embedding space of Point-Bind, we can generate the 3D mesh conditioned on any modalities, and also modify the appearance of existing 3D shapes with multi-modal instructions. In detail, we simply utilize a learnable projection layer to align our joint embedding space with the pre-trained decoder of existing 3D generation methods, e.g., ISS (Liu et al., 2022) by single view reconstruction (SVR). We only tune the projection layer while keeping other networks frozen. After this, we directly connect the multi-modal encoders of Point-Bind with the decoders of ISS, which is capable of synthesizing a 3D car mesh based on an input car horn. Also, we can feed an existing 3D shape using Point-Bind’s 3D encoder, and provide multi-modal instruction signals to modify its appearance, e.g., coloring an airplane in red or changing a chair’s material to wooden.
+
+3D Zero-shot Understanding. For traditional text-inferred 3D zero-shot classification, PointBind attains state-of-the-art performance guided by additional multi-modal supervision. Besides, Point-Bind can also achieve audio-referred 3D open-world understanding, i.e., recognizing 3D shapes of novel categories indicated by the corresponding audio data (Piczak, 2015).
+
+# 3 POINT-LLM
+
+In this section, we illustrate how to leverage the emergent characteristic of Point-Bind to develop 3D large language models (LLMs), termed as Point-LLM, which enables a pre-trained ImageBindLLM (Han et al., 2023) to achieve 3D question answering and multi-modal reasoning in a trainingfree manner. The overall pipeline of Point-LLM is shown in Figure 3.
+
+3D Instruction-following Capacity. Our Point-LLM is developed on top of a pre-trained ImageBind-LLM (Han et al., 2023), which conducts multi-modality instruction tuning by injecting the semantics of ImageBind into LLaMA. By vision-language pre-training, ImageBind-LLM has already aligned the joint embedding space of ImageBind with LLaMA using a bind network, which shares the same space with our Point-Bind. Considering this, we can directly bridge PointBind with LLaMA using the pre-trained bind network. Therefore, our Point-LLM does not require any 3D instruction data for training, and efficiently endows LLaMA with 3D understanding capability, which also inherits the pre-trained bilingual ability of ImageBind-LLM. This significantly saves the resources for annotating 3D instruction data and large-scale training,
+
+Inference with Visual Cache. For a given language instruction and a 3D point cloud, we input them into LLaMA and our Point-Bind, respectively. Then, before feeding the encoded 3D feature into the bind network, we adopt a visual cache model for 3D feature enhancement. As ImageBindLLM adopts the image encoder of ImageBind for training, but we switch to Point-Bind’s 3D encoder for inference, the cache model is designed to alleviate such 2D-3D modality discrepancy for better 3D geometry understanding. Specifically, the cache model stores three million ImageBind-encoded image features from the training data, which are regarded as both keys and values for knowledge retrieval. We regard the input 3D feature as the query, and retrieve the top- $k$ similar visual keys from the cache. Then, according to the cosine similarity, we aggregate the corresponding cached values (top- $k$ similar image features), and add the result to the original 3D feature via a residual connection. The enhanced 3D feature can adaptively incorporate similar 2D semantics from the cache model. Such a strategy mitigates the semantic gap of 2D-3D encoders, and boosts the representation quality of 3D shapes in Point-LLM. After this, the enhanced feature is fed into the bind network for transformation and LLaMA for response generation.
+
+![](images/2b21556645e3fcf1837cc1e6cd50b77244eb8985eb59e62c182e3ff50fdf6fb2.jpg)  
+Figure 7: Embedding-space Arithmetic of 3D and Audio. To demonstrate our semantic composition ability, we retrieve 2D images with a combination of 3D point cloud and audio embeddings.
+
+3D and Multi-modal Reasoning. In addition to point clouds, considering the joint embedding space of Point-Bind, our Point-LLM can also conduct cross-modal reasoning and generate responses conditioned on multiple modalities. For an additional input image or audio, we utilize the image or audio encoder of ImageBind to extract the features, and directly add them with the 3D feature encoded by Point-Bind. By injecting such integrated features into LLaMA, Point-LLM can reason cross-modal semantics, and respond with the information of all input modalities. This demonstrates the promising significance of aligning multi-modality with 3D LLMs.
+
+# 4 EXPERIMENTS
+
+In this section, we respectively illustrate the emergent multi-modal applications of Point-Bind, i.e., Point-LLM for 3D instruction following, composed 3D cross-modal retrieval, any-to-3D generation, and 3D zero-shot understanding. Then, we conduct ablation studies to verify the effectiveness of our designs. Please refer to Supplementary Material for training details of Point-Bind.
+
+# 4.1 POINT-LLM FOR 3D Q&A
+
+Settings. Our method is built on a pre-trained ImageBind-LLM (Han et al., 2023), which adopts LLaMA 7B (Touvron et al., 2023) as the foundation LLM and ImageBind with a ViT-H image encoder. Note that we do not conduct any training for Point-LLM, thanks to the instruction tuning of ImageBind-LLM. As there is no existing benchmark for 3D instruction models, referring to Vicuna (Vicuna, 2023), we adopt two powerful LLMs, GPT-4 (OpenAI, 2023) and Bard (Google, 2023), for evaluation, and sample 1,000 3D-caption pairs from Cap3D (Luo et al., 2023) as the test set, which is a large-scale 3D object captioning dataset built upon Objaverse (Deitke et al., 2023). Specifically, for two generated responses to compare, we feed them into the evaluator LLM to ask which one is closer to the ground-truth caption, and count the number of ‘Win’, ‘Tie’, and ‘Lost’ for comparison. We regard ImageBind-LLM as a baseline, which takes one rendered image of the point cloud as input for 3D Q&A.
+
+Analysis. In Figure 6, we present the results evaluated by GPT-4 and Bard. Compared to the baseline ImageBind-LLM, by using our Point-Bind for 3D encoding, Point-LLM achieves significantly more ‘Win’. This fully indicates our Point-Bind aligned with multi-modality can better extract 3D spatial geometries than ImageBind’s 2D encoder. If we do not adopt the visual cache model, the 3D question-answering performance would be severely harmed, due to the 2D-3D modality discrepancy between training and inference. In Figure 3, we provide the question-answering examples of Point-LLM, which shows favorable 3D instruction-following and multi-modal reasoning capacity. As shown, for either English or Chinese instructions, Point-LLM can effectively incorporate the spatial geometry of input point clouds and generate detailed language responses. It obtains a comprehensive 3D understanding for both global and local characteristics, e.g., recognizing the pattern of the piano keyboard and the shape of the airplane’s wing and tail. Then, our Point-LLM can also respond with cross-modal understanding. For an input 3D model with a 2D image or audio, PointLLM can enable LLaMA to take both two conditions into understanding and reasoning, which thus incorporates multi-modal semantics in the output language response.

+
+# 4.2 COMPOSED 3D CROSS-MODAL RETRIEVAL
+
+3D Cross-modal Retrieval. To evaluate the multi-modal alignment of Point-Bind, we first experiment with several cross-modal retrieval tasks between 3D and another modality, i.e., 2D and text. We evaluate our method on the multi-modal ModelNet40 (Wu et al., 2015) dataset, and obtain the retrieved results by ranking feature similarities. As shown in Table 1, our Point-Bind attains leading performance on all benchmarks compared with prior works (Zhang et al., 2022b; Zhu et al., 2022; Xue et al., 2022; 2023). In particular, for 2D-to-3D and text-to-3D retrieval, Point-Bind surpasses the ULIP (Xue et al., 2022) significantly by $+ 1 4 . 2 9 \%$ and $+ 1 3 . 9 9 \%$ , respectively. This indicates the superior cross-modal understanding capacity of our approach.
+
+Embedding-space Arithmetic. With the multi-modal alignment, we further explore the capability of embedding composition, i.e., the embedding-space arithmetic of 3D and other modalities, e.g., audio. We utilize 3D objects from ShapeNet (Chang et al., 2015) and TextANIMAR 2023 (Challenge, 2023), and audio clips from ESC-50 (Piczak, 2015). We simply add the 3D and audio embeddings respectively from Point-Bind and ImageBind, and retrieve 2D images from ImageNet (Deng et al., 2009). In Figure 7, we show the results of 2D image retrieval with the composed embeddings between 3D and audio. As shown in the first row, with the combined embeddings of a 3D dog and sea-wave audio, we effectively retrieve 2D images of dogs by the sea. Similarly, with the combination of a 3D laptop and keyboard-typing audio, the obtained images show someone is working with a laptop, or a cat inadvertently presses on the keyboard. Likewise, the last row retrieves images of bears hunting by the water by using embeddings of a 3D bear and audio of flowing water. The examples demonstrate the 3D features from Point-Bind can be directly added with other aligned modalities, and incorporate their semantics, achieving favorable composed cross-modal retrieval.
+
+# 4.3 ANY-TO-3D GENERATION
+
+Settings. We adopt a learnable projection layer to connect the decoder of ISS (Liu et al., 2022) with the embedding space of Point-Bind by single view reconstruction (SVR). For quantitative evaluation, we compare several existing methods (Sanghi et al., 2021; Jain et al., 2022b; Liu et al., 2022) for text-to-3D generation, and adopt three criteria, Frechet Inception Distance (FID) ( ´ Heusel et al., 2017), Frechet Point Distance (FPD) ( ´ Shu et al., 2019), and CLIP R-Precision (RP) (Park et al., 2021). Please refer to Supplementary Material for 3D generation with other modalities and their composition.
+
+Analysis. In Table 2, the quantitative comparison shows our approach achieves lower FID/FPD values, outperforming other methods for both 3D generation quality and shape correspondence. The competitive CLIP R-Precision score also suggests a higher consistency between text and 3D shapes of our method. In Figure 2, we also show several qualitative results of any-to-3D generation and instruction-based editing powered by Point-Bind, e.g., generating 3D meshes from audio and point clouds, along with 3D shape editing by input language instructions (More visualizations are shown in Supplementary Material). This demonstrates the well-aligned embedding space of 3D and multiple modalities in Point-Bind.
+
+# 4.4 3D ZERO-SHOT UNDERSTANDING
+
+We investigate our open-word understanding ability, i.e., recognizing novel classes, by 3D zero-shot classification on ModelNet40 (Wu et al., 2015) and ScanObjectNN (Uy et al., 2019) datasets.
+
+Settings. Following previous CLIP-based works, we utilize the text embeddings from ImageBind’s (Girdhar et al., 2023) text encoder to construct the zero-shot classifier. Specifically, we apply a simple template of ‘a [CLASS]’ for the 40/15 categories of ModelNet40/ScanObjectNN, and calculate the cosine similarity between 3D and all textual embeddings, selecting the most similar one as the final prediction. Moreover, as our 3D embeddings are also aligned with the audio modality, our approach also supports the audio-referred 3D zero-shot recognition by regarding audio embeddings of different categories as the classifier.
+
+Analysis. We report the 3D zero-shot classification accuracy in Table 3, where our Point-Bind can surpass existing methods (Zhang et al., 2022b; Zhu et al., 2022; Xue et al., 2022; 2023) on both benchmarks. With the same encoder as Point-BERT (Yu et al., 2022), our approach outperforms ULIP by significant margins, $+ 1 5 . 9 \%$ and $+ 1 1 . 4 \%$ accuracy on the two datasets. For audio-referred 3D classification, we select six categories that can make a sound in ModelNet40 for evaluation (airplane, car, guitar, keyboard, piano, toilet), for which our Point-Bind attains $8 9 . 3 \%$ accuracy, a little worse than the text-referred $9 1 . 8 \%$ . This indicates the unified representation space of PointBind leads to strong emergent 3D open-world recognition.
+
+# 4.5 ABLATION STUDY
+
+In Table 4, we conduct two ablation studies to verify the effectiveness of the multi-modal training and 3D encoder selection in Point-Bind. We report the zero-shot classification accuracy on ModelNet40. In the left part of the table, we progressively add the modality in training data, and observe the performance increasing. This indicates the contrastive supervision from more modalities contributes to a better 3D joint embedding space. In the right

+part, we utilize different 3D encoders in Point-Bind, i.e., Point-BERT (Yu et al., 2022), PointNeXt (Qian et al., 2022a), and I2P-MAE (Zhang et al., 2023a). As reported, the pre-trained PointBERT and I2P-MAE can achieve much better performance, indicating the importance of 3D pretraining to boost the multi-modal alignment.
+
+# 5 CONCLUSION
+
+In this paper, we propose Point-Bind, a general 3D multi-modality model that aligns 3D point clouds with multi-modalities, guided by ImageBind. By aligning 3D objects with their corresponding image-audio-text pairs, Point-Bind obtains a joint embedding space, and exhibits promising 3D multi-modal tasks, such as any-to-3D generation, 3D embedding arithmetic, and 3D open-world understanding. The emergent ability of Point-Bind significantly lowers the bar for efficiently achieving many new cross-modal applications. Upon that, we further introduce Point-LLM, a 3D large language model (LLM) with superior instruction-following and multi-modal reasoning capabilities. Extensive experiments have demonstrated the effectiveness and significance of our 3D multi-modal framework. Future work will focus on aligning multi-modality with more diverse 3D data, such as indoor and outdoor scenes, which allows for a wider range of 3D-centric scenarios.

+
+Cross-modal Retrieval on More Modalities. To verify the potential of Point-Bind to align multimodalities, we conduct cross-modal retrieval between 3D and more modalities, i.e., video, depth, and infrared data. We utilize the following work of ImageBind (Girdhar et al., 2023), LanguageBind (Zhu et al., 2023a), as guidance, and pre-train Point-Bind under the same paradigm. By aligning 3D with the image space of LanguageBind, Point-Bind achieves a unified space with multimodalities including video, depth, and infrared data. As shown in Figure 8, with the 3D car/person as input, Point-Bind effectively retrieves corresponding video, depth, and infrared data with the same semantics. This indicates the superior cross-modal understanding capacity of our approach.

+Figure 8: Additional Visualization of Cross-modal Retrieval. We visualize the cross-modal retrieval between 3D and three new modalities, i.e., video, depth, and infrared data. Note that, for these modalities, we utilize LanguageBind (Zhu et al., 2023a) as the guidance for pre-training Point-Bind.
+
+Quantitative Results of Any-to-3D Genration. Besides text-to-3D generation, we quantitatively demonstrate the efficacy of Point-Bind on any-to-3D generation in Table 5. We generate the 3D mesh conditioned on multi-modalities and their embedding-space arithmetic, i.e., directly combining embeddings from different modalities to guide 3D generation. We adopt different settings for different modalities. For audio-to-mesh generation, we only generate objects of the car, airplane, and boat categories considering the limited class number. We sample 10 audio clips per category from ESC50 dataset (Piczak, 2015) as input. The airplane takeoff sound, car horn, and sea wave sound are selected to generate the airplane, car, and boat categories, respectively. For image-to-mesh generation, we sample 10 images corresponding to ShapNet’s 13 categories from ImageNet dataset (Deng et al., 2009) as the 2D prompt. For point-to-mesh synthesis, we sample 10 point clouds per category from the ShapeNet dataset (Chang et al., 2015) as prompt. Compared to text-to-3D generation, the results in Table 5 suggest that Point-Bind can also achieve satisfactory generation quality with other modalities as conditions.

+
+Any-to-3D Generation with CLIP-Forge (Sanghi et al., 2021). Besides ISS (Liu et al., 2022), we also adopt the decoder of CLIP-Forge and show the examples of any-to-3D generation powered by Point-Bind in Figure 9. For text, audio, and point cloud prompts, our approach can all produce satisfactory 3D meshes. This demonstrates that Point-Bind generalizes well and can guide other 3D generation models conditioned on multi-modalities.
+
+3D Editing with Multi-modal Instructions. Besides the any-to-3D generation, our approach can further enable 3D editing with multi-modal instructions, as visualized in Figure 10. For example, given a 3D airplane, we can provide a language instruction, “Color the 3D shape in red”, or a pure yellow picture as the visual instruction. Then, we respectively feed them into Point-Bind’s 3D encoder and ImageBind’s text or image encoder. Due to the joint embedding space, the generative decoder can incorporate their semantics and output the airplane in red/yellow. Likewise, given an ordinary 3D bench, we can provide instructions like “Modify the material to wooden”. The model can correspondingly generate a wooden chair. Therefore, benefiting from the emergent capacity of Point-Bind, we can simply achieve any-to-3D generation and editing, exhibiting favorable training efficiency and generalization capability.
+
+Additional Comparison and Analysis with ULIP. The teacher model of Point-Bind, ImageBind (Girdhar et al., 2023), has different pre-training settings with ULIP’s (Xue et al., 2022) teacher model, SLIP (Mu et al., 2021). In this paragraph, we compare Point-Bind and ULIP with the same pre-trained teacher models. We first reproduce a ULIP model also pre-trained by CLIP’s ViT-H image encoder, which is the same as ImageBind’s image encoder. Note that, ImageBind freezes the ViT-H image encoder and text encoder of OpenCLIP during its pre-training. That is, ImageBind and OpenCLIP share the same weights in their image and text encoders. As shown in Table 6, for zero-shot classification on ModelNet40 (Wu et al., 2015), although the ULIP’s performance can be improved by the ViT-H image encoder, our approach still performs better via a joint multi-modal embedding space.
+
+Generalizability of Point-Bind with Techniques from JM3D (Wang et al., 2023a). JM3D (Wang et al., 2023a) proposes two delicate approaches to enhance the multi-modal pretraining of 3D models: Structured Multimodal Organizer (SMO) and Joint Multi-modal Alignment (JMA). SMC adopts multi-view rendered images and hierarchical text for more comprehensive representation, and JMA aims to achieve better mult-modal synergy by generating joint vision-language features. We also add the two techniques in JM3D into our Point-Bind for the image and text modalities within ImageBind (Girdhar et al., 2023), and evaluate on two benchmarks: 3D zero-shot classification and cross-modal retrieval on ModelNet40 (Wu et al., 2015). As shown in Table 7, the capabilities of Point-Bind are well enhanced by integrating SMO and JMA, indicating the importance of more comprehensive vision-language guidance.

+
+Generalizability of Point-Bind with Techniques from CG3D (Hegde et al., 2023). CG3D (Hegde et al., 2023) shares a similar contrastive learning paradigm with ULIP, and introduces learnable visual prompts for CLIP’s image encoder for better adaption of 2D rendered images. For our Point-Bind, we also add learnable visual prompts to the image encoder of ImageBind, and report the results in Table 7. On both benchmarks, the prompting approach from CG3D can improve the performance of Point-Bind, which demonstrates the effectiveness of fine-tuning the pre-trained image embeddings.

+Point-LLM. As shown, given a 3D shape with a 2D image or audio, Point-LLM effectively enables LLaMA (Touvron et al., 2023) injected with multi-modal semantics, and responds with cross-modal understanding and reasoning. Additionally, as shown in Figure 12, we show more examples of Point-LLM for straightforward question answering, e.g., “How to start it?”, “What is the purpose of this thing?”. Our model can respond with precise answers that correspond to the input point cloud.
+
+Examples of Indoor Scene Understanding. We further implement a scene-level variant of our model, termed Point- $\mathbf { \cdot L L M } _ { \mathrm { S c e n e } }$ . We focus on the understanding of indoor scenes on ScanNet (Dai et al., 2017), and show the qualitative examples in Figure 13. Specifically, to obtain the scenelevel understanding capacity, we fine-tune our object-level Point-LLM by an existing 3D questionanswering dataset (Wang et al., 2023c) constructed from ScanRefer (Chen et al., 2020a). We add three MLP layers with residual connections between Point-Bind’s 3D encoder and the LLM, which is responsible for learning the scene-level 3D geometries. We only enable the new MLP layers to be trainable, while keeping other components frozen to preserve the pre-trained cross-modal knowledge. As shown, our model can respond with detailed and reasonable answers that correspond to the input 3D scene and target object.

+# C RELATED WORK
+
+Multi-modality Learning. Compared to single-modal approaches, multi-modal learning aims to learn from multiple modalities simultaneously, achieving more robust and diverse representation learning. Numerous studies have proved its efficacy, involving 2D images, videos, texts, and audio (Desai & Johnson, 2021; Fang et al., 2021; Nagrani et al., 2022), and enhance the cross-modal performance for downstream tasks (Lin et al., 2021b; Ramesh et al., 2021; Botach et al., 2022; Guo et al., 2023c), and video-text-audio integration for text generation (Lin et al., 2021a). The representative vision-language pre-training, CLIP (Radford et al., 2021), effectively bridges the gap between 2D images and texts, which encourages further exploration of cross-modality learning. Recently, ImageBind (Girdhar et al., 2023) successfully aligns six modalities in a joint embedding space, unleashing the power for emergent zero-shot cross-modal capabilities. However, ImageBind fails to investigate its efficacy on 3D point clouds. In the 3D domain, most existing cross-modal works introduce vision-language alignment (Zhang et al., 2022b; Xue et al., 2022; Afham et al., 2022; Guo et al., 2023a; Chen et al., 2023a) into 3D point clouds, and mainly focus on open-world recognition tasks, which ignore the potential of multi-modal semantics for wider 3D applications. In this paper, our Point-Bind develops a general 3D multi-modality model that aligns 3D point clouds with six other modalities guided by ImageBind, allowing for more diverse 3D cross-modal understanding.
+
+Large Models in 3D. Large-scale pre-trained models have achieved remarkable downstream performance in language and 2D image processing. Inspired by this, many efforts have introduced 2D and language large models, to assist in 3D learning. The prior PointCLIP series (Zhang et al., 2022b; Zhu et al., 2022; Huang et al., 2022) project 3D point clouds into depth maps, and utilize CLIP (Radford et al., 2021) for zero-shot recognition. Image2Point (Xu et al., 2022) instead converts 2D pre-trained models into 3D space as a good network initialization. By contrastive learning, ULIP series (Xue et al., 2022; 2023) and other works (Liu et al., 2023a; Hegde et al., 2023) pre-train 3D networks guided by the vision-language embedding space of CLIP. Another branch of work employs CLIP to guide the text-conditioned generation of 3D objects (Jain et al., 2022a; Sanghi et al., 2021; Xu et al., 2023a; Liu et al., 2023b) or stylized meshes (Mohammad Khalid et al., 2022; Michel et al., 2021) by encoding descriptive textual input. Some works also adopt GPT-3 (Brown et al., 2020) to enhance the language-based understanding of 3D spatial geometry, such as PointCLIP V2 (Zhu et al., 2022) and ViewRefer (Guo et al., 2023b). Different from them, we utilize

There are a couple of very recent efforts that introduce LLMs into 3D, concurrent to our Point-LLM. Different from us, they either project 3D data into multi-view images for encoding (Hong et al., 2023b), or require large

+scale 3D instruction data for fine-tuning (Xu et al., 2023b; Wang et al., 2023b). More importantly, they cannot generate responses conditioned on both 3D and multi-modal input. Thanks to the joint embedding space of Point-Bind, our Point-LLM can discard the expensive 3D instruction tuning, and respond via 3D multi-modal reasoning.
+
+Pre-training in 3D. In recent years, significant progress has been made in supervised learning for 3D vision tasks (Qi et al., 2016; 2017; Qian et al., 2022a; Zhang et al., 2023b; Zhu et al., 2023b). However, these approaches lack satisfactory generalization capabilities for out-of-domain data. To address this, self-supervised learning has emerged as a promising solution to enhance
+
+3D transfer learning (Chen et al., 2023a; Yu et al., 2022; Li et al., 2019; Poursaeed et al., 2020). Most self-supervised pre-training methods employ an encoder-decoder framework to encode point clouds into latent representations and then reconstruct the original data form (Sauder & Sievers, 2019; Wang et al., 2021; Rao et al., 2020). Therein, Point-MAE (Pang et al., 2022) and PointM2AE (Zhang et al., 2022a) introduce masked autoencoders (He et al., 2021) into 3D point clouds pre-training, achieving competitive results on different 3D tasks. Alternatively, cross-modal pretraining approaches are also leveraged to enhance the 3D generalization ability (Wang et al., 2022; Qian et al., 2022b; Liu et al., 2021a; Qi et al., 2023). For example, ACT (Dong et al., 2022) and I2P-MAE (Zhang et al., 2023a) utilize pre-trained 2D transformers as teachers to guide 3D representation learning. Inspired by previous works, we adopt collected 3D-image-text-audio pairs for self-supervised pre-training, and regard ImageBind’s encoders as guidance for contrastive learning. In this way, the Point-Bind is pre-trained to obtain a joint embedding space between 3D and multi-modality, allowing for superior performance on different 3D downstream tasks.
+
+# D ADDITIONAL IMPLEMENTATION DETAILS
+
+Multi-modal Training of Point-Bind. To align 3D with multi-modalities, we adopt a pre-trained I2P-MAE (Zhang et al., 2023a) as the 3D encoder of Point-Bind by default, and utilize the collected 3D-image-text-audio pairs for pre-training. We utilize a pre-trained ImageBind (Girdhar et al., 2023) with a ViT-H (Dosovitskiy et al., 2020) image encoder. We only update the 3D encoder with the newly added projection network, and freeze the encoders of other modalities in ImageBind. The projection network is composed of two linear layers with an intermediate LayerNorm (Ba et al., 2016). We train Point-Bind for 300 epochs with a batch size of 64, and adopt AdamW (Loshchilov & Hutter, 2017) as the optimizer with a learning rate of 0.003.
+
+3D Cross-modal Retrieval. We utilize ModelNet40 (Wu et al., 2015) to evaluate Point-Bind on cross-modal retrieval tasks without training. The test set of ModelNet40 provides 2,468 samples with two modalities, i.e., 2D images rendered from 3D meshes and corresponding 3D point clouds. We adopt the Mean Average Precision (mAP) score as the criterion, which measures whether the retrieved data belongs to the same class as the query data. We encode 3D point clouds with PointBind and conduct four cross-modal retrieval tasks, i.e., 3D-to-3D, 2D-to-3D, 3D-to-2D, and text-to3D retrieval. For the text prompt, we adopt and separately encoder 64 prompt templates in ULIP (Xue et al., 2022) on each category, and average them as the text embeddings. For the 2D image prompt, we follow (Jing et al., 2021) to utilize multi-view images where the view number is $\in$ $\bar { \{ 1 , 2 , 4 \} }$ . We average the performance under the three view settings as the final result.
+
+Any-to-3D Generation. We adopt Image as Stepping Stone (ISS) (Liu et al., 2022) to verify PointBind’s ability of multi-modal feature alignment. We first optimize a projection layer that transfers Point-Bind image features to ISS 3D shape space. Then, we generate 3D shapes from text features based on the pre-trained projection layer and ISS decoder. The ShapeNet (V2) dataset(Chang et al., 2015) with 13 object categories is utilized to train the model. We follow ISS and adopt a text description set with four texts per category. To demonstrate 3D generation quality, we adopt FID, FPD, and CLIP R-precision as criteria. FID reflects the quality of rendered 2D images from generated 3D shapes. FPD measures the quality of point clouds extracted from generated shapes based on a pre-trained PointNet model (Qi et al., 2016) following ISS. Additionally, we further adopt CLIP R-precision to evaluate the consistency between the text inputs and generated shapes. We build a text description set, which contains our description prompts and 234 additional texts from CLIP-Forge (Sanghi et al., 2021). Then, we perform per-shape CLIP-R-Precision to retrieve the right description for each generated shape and calculate the retrieval accuracy. To give a comprehensive comparison, we mainly compare our approach to three text-to-mesh generation models, CLIP-Forge (Sanghi et al., 2021), Dream Fields (Jain et al., 2022b), and ISS. Note that Dream Fields can not synthesize 3D shapes directly, so we do not need to evaluate its FPD metric. In addition, two baselines, GLIDE/LAFITE $^ +$ DVR, which first create images and then generate 3D meshes are also included. Following ISS, we first use GLIDE (Nichol et al., 2021) or LAFITE (Zhou et al., 2022) to create 2D images and then generate 3D shapes via DVR (Niemeyer et al., 2020).

However, in 3D domains, how to develop an all-purpose multi-modal framework is still under-explored. To this end, we introduce Point-Bind, a 3D multi-modality model aligning point clouds with 2D image, language, audio, and video. Guided by ImageBind, we construct a joint embedding space between 3D and multi-modalities, enabling many promising applications, e.g., 3D embedding arithmetic, any-to-3D generation, and 3D open-world understanding. On top of this joint embedding space, we further present Point-LLM, a 3D large language model extending ImageBindLLM to follow 3D and multi-modal instructions. Without any 3D instruction data, our Point-LLM injects the semantics of Point-Bind into pre-trained LLMs, e.g., LLaMA, and exhibits superior 3D and multi-modal question-answering capacity. We have conducted extensive experiments to demonstrate the effectiveness and generalizability of our approach for aligning 3D and multi-modality. ",

To extend its application scenarios, numerous efforts have been made to incorporate 3D point clouds with other modalities, allowing for improved 3D understanding (Guo et al., 2023a; Afham et al., 2022), text-to-3D generation (Nichol et al., 2022; Poole et al., 2022), and 3D question answering (Azuma et al., 2022; Hong et al., 2023a).

However, their perception capabilities are mostly constrained by limited modalities provided in the training phase. Inspired by 2D generative models, a collection of methods (Lin et al., 2023; Nichol et al., 2022) has achieved text-to-3D synthesis with high quality and efficiency. Despite this, they lack the ability to generate 3D shapes conditioned on multi-modal input, e.g., a sound and an image. Another series of works connects descriptive natural language with 3D data, applying to 3D captioning (Yuan et al., 2022; Chen et al., 2023b) and question answering (Wijmans et al., 2019; Azuma et al., 2022). Yet, they fail to utilize the pre-trained linguistic knowledge within large language models (LLMs) to better reason 3D geometries. Therefore, how to develop a unified 3D framework aligning with multi-modality for general 3D learning still remains an open question. Very recently, ImageBind (Girdhar et al., 2023) is proposed to learn a shared representation space across six different modalities, i.e., image, text, audio, depth, thermal, and IMU data. Motivated by this, we ask the following question: can we construct a joint embedding space between 3D and multi-modality for unified 3D understanding, generation, and instruction following? ",

As ImageBindLLM adopts the image encoder of ImageBind for training, but we switch to Point-Bind’s 3D encoder for inference, the cache model is designed to alleviate such 2D-3D modality discrepancy for better 3D geometry understanding. Specifically, the cache model stores three million ImageBind-encoded image features from the training data, which are regarded as both keys and values for knowledge retrieval. We regard the input 3D feature as the query, and retrieve the top- $k$ similar visual keys from the cache. Then, according to the cosine similarity, we aggregate the corresponding cached values (top- $k$ similar image features), and add the result to the original 3D feature via a residual connection. The enhanced 3D feature can adaptively incorporate similar 2D semantics from the cache model. Such a strategy mitigates the semantic gap of 2D-3D encoders, and boosts the representation quality of 3D shapes in Point-LLM.

Note that we do not conduct any training for Point-LLM, thanks to the instruction tuning of ImageBind-LLM. As there is no existing benchmark for 3D instruction models, referring to Vicuna (Vicuna, 2023), we adopt two powerful LLMs, GPT-4 (OpenAI, 2023) and Bard (Google, 2023), for evaluation, and sample 1,000 3D-caption pairs from Cap3D (Luo et al., 2023) as the test set, which is a large-scale 3D object captioning dataset built upon Objaverse (Deitke et al., 2023). Specifically, for two generated responses to compare, we feed them into the evaluator LLM to ask which one is closer to the ground-truth caption, and count the number of ‘Win’, ‘Tie’, and ‘Lost’ for comparison.

This fully indicates our Point-Bind aligned with multi-modality can better extract 3D spatial geometries than ImageBind’s 2D encoder. If we do not adopt the visual cache model, the 3D question-answering performance would be severely harmed, due to the 2D-3D modality discrepancy between training and inference. In Figure 3, we provide the question-answering examples of Point-LLM, which shows favorable 3D instruction-following and multi-modal reasoning capacity. As shown, for either English or Chinese instructions, Point-LLM can effectively incorporate the spatial geometry of input point clouds and generate detailed language responses. It obtains a comprehensive 3D understanding for both global and local characteristics, e.g., recognizing the pattern of the piano keyboard and the shape of the airplane’s wing and tail. Then, our Point-LLM can also respond with cross-modal understanding. For an input 3D model with a 2D image or audio, PointLLM can enable LLaMA to take both two conditions into understanding and reasoning, which thus incorporates multi-modal semantics in the output language response.

Compared to single-modal approaches, multi-modal learning aims to learn from multiple modalities simultaneously, achieving more robust and diverse representation learning. Numerous studies have proved its efficacy, involving 2D images, videos, texts, and audio (Desai & Johnson, 2021; Fang et al., 2021; Nagrani et al., 2022), and enhance the cross-modal performance for downstream tasks (Lin et al., 2021b; Ramesh et al., 2021; Botach et al., 2022; Guo et al., 2023c), and video-text-audio integration for text generation (Lin et al., 2021a). The representative vision-language pre-training, CLIP (Radford et al., 2021), effectively bridges the gap between 2D images and texts, which encourages further exploration of cross-modality learning. Recently, ImageBind (Girdhar et al., 2023) successfully aligns six modalities in a joint embedding space, unleashing the power for emergent zero-shot cross-modal capabilities. However, ImageBind fails to investigate its efficacy on 3D point clouds. In the 3D domain, most existing cross-modal works introduce vision-language alignment (Zhang et al., 2022b; Xue et al., 2022; Afham et al., 2022; Guo et al., 2023a; Chen et al., 2023a) into 3D point clouds, and mainly focus on open-world recognition tasks, which ignore the potential of multi-modal semantics for wider 3D applications.

Then, we generate 3D shapes from text features based on the pre-trained projection layer and ISS decoder.

To demonstrate 3D generation quality, we adopt FID, FPD, and CLIP R-precision as criteria. FID reflects the quality of rendered 2D images from generated 3D shapes. FPD measures the quality of point clouds extracted from generated shapes based on a pre-trained PointNet model (Qi et al., 2016) following ISS. Additionally, we further adopt CLIP R-precision to evaluate the consistency between the text inputs and generated shapes. We build a text description set, which contains our description prompts and 234 additional texts from CLIP-Forge (Sanghi et al., 2021). Then, we perform per-shape CLIP-R-Precision to retrieve the right description for each generated shape and calculate the retrieval accuracy.

+# ABSTRACT
+
+Training large language models (LLMs) with open-domain instruction following data brings colossal success. However, manually creating such instruction data is very time-consuming and labor-intensive. Moreover, humans may struggle to produce high-complexity instructions. In this paper, we show an avenue for creating large amounts of instruction data with varying levels of complexity using LLM instead of humans. Starting with an initial set of instructions, we use our proposed Evol-Instruct to rewrite them step by step into more complex instructions. Then, we mix all generated instruction data to fine-tune LLaMA. We call the resulting model WizardLM. Both automatic and human evaluations consistently indicate that WizardLM outperforms baselines such as Alpaca (trained from SelfInstruct) and Vicuna (trained from human-created instructions). The experimental results demonstrate that the quality of instruction-following dataset crafted by Evol-Instruct can significantly improve the performance of LLMs.
+
+# 1 INTRODUCTION
+
+Large-scale language models (LLMs) have become the go-to approach for numerous natural language processing tasks (Brown et al., 2020; Ouyang et al., 2022; Touvron et al., 2023). LLMs are trained on large volumes of text data to predict the subsequent tokens, enabling them to generate coherent and fluent text in response to various inputs. However, these models often struggle to follow instructions or goals specified by users, which limits their usefulness and applicability in real-world scenarios.
+
+The NLP community has recently witnessed many endeavors to train LLMs to follow instructions better and be more helpful (Zhao et al., 2023; He et al., 2023; Guo et al., 2023; Li et al., 2023b). Initial attempts (Aribandi et al., 2022; Wei et al., 2021; Xu et al., 2022; Sanh et al., 2022; Chung et al., 2022) to train instruction-following language models are based on a collection of various NLP tasks, with a small amount of hand-written instructions. These closed-domain instructions suffer from two main drawbacks: first, all the samples in an NLP dataset share only a few common instructions, severely limiting their diversity; second, the instructions usually only ask for one task. But in real life, human instructions often have multiple and varied task demands. By using open-domain instruction data generated by real human users, OpenAI’s LLMs (e.g., InstructGPT (Ouyang et al., 2022) and ChatGPT 1) have achieved great success. These open-domain instructions can fully unleash the unlimited potential of LLMs (Luo et al., 2023; Ma et al., 2023; Hu et al., 2023; Zhu et al., 2023) and enable them to perform more complex and diverse tasks. However, using humans to create open-domain instruction datasets like OpenAI did will encounter the following challenges. The whole annotating process is extremely expensive and time-consuming (Kopf et al., 2023; Chen et al., 2023; Sun et al., 2023; Yuan et al., 2023). On the other hand, the difficulty level distribution of humancreated instructions is skewed towards being easy or moderate, with fewer difficult ones (according to the difficulty statistics of ShareGPT (Chiang et al., 2023) from Figure 5a). Human annotators are prone to fatigue and cannot sustain high-intensity work to produce a sufficient proportion of high-difficulty instructions (Zhang et al., 2023; Xiao et al., 2023; Manakul et al., 2023; Zhong et al., 2023). Based on these issues, developing an automatic method that can mass-produce open-domain instructions (especially the more difficult ones) at a relatively low cost becomes the key to further advancing instruction-tuned language models (Bao et al., 2023; Liu et al., 2023; Bian et al., 2023; Cabannes et al., 2023).

+Figure 1: Running Examples of Evol-Instruct.
+
+In this work, we introduce Evol-Instruct, a novel method using LLMs instead of humans to automatically mass-produce open-domain instructions of various difficulty levels, to improve the performance of LLMs. Figure 1 shows the running examples of Evol-Instruct. Starting from a simple initial instruction $\mathrm { \Omega ^ { 6 6 } 1 + 1 = 2 \Omega ^ { 5 5 } }$ , our method randomly selects In-depth Evolving (blue direction line) or In-breadth Evolving (red direction line) to upgrade the simple instruction to a more complex one or create a new one (to increase diversity). The In-depth Evolving includes five types of operations: add constraints, deepening, concretizing, increase reasoning steps, and complicate input. The In-breadth Evolving is mutation, i.e., generating a completely new instruction based on the given instruction. These six operations are implemented by prompting an LLM with specific prompts. Since the evolved instructions are generated from LLMs, sometimes the evolving will fail. We adopt an instruction eliminator to filter the failed instructions, which is called Elimination Evolving. We repeat this evolutionary process for several rounds to obtain enough instruction data containing various complexities.
+
+In order to verify the effectiveness of Evol-Instruct and whether the instructions it creates for finetuning surpass those created by humans, we evolve the instructions from Aplaca (Taori et al., 2023) data (created by machine), fine-tune the LLaMA (Touvron et al., 2023) model, and comprehensively compare the fine-tuned model WizardLM with Vicuna (Chiang et al., 2023) trained on ShareGPT (instructions are created by human). Alpaca data has a total of $5 2 k$ samples and is generated using self-instruct (Wang et al., 2022a) from only 175 human-created seed instructions. We choose Alpaca data as the initial data for evolution, which can ensure that the training instructions of WizardLM have almost no direct human participation in annotations. We execute four epochs of evolution using OpenAI ChatGPT $\mathrm { \ A P I ^ { 2 } }$ and finally obtain $2 5 0 k$ instructions. To ensure a fair comparison with Vicuna’s $7 0 k$ real user data, we sampled $7 0 k$ from the full $2 5 0 k$ data and fine-tuned the LLaMA 13B model. Because the original Alpaca data only has $5 2 k$ samples, we used its self-instruct method to generate an additional $1 8 k$ data, and retrained the LLaMA 13B model with its code3 to get Alpaca 13B as our baseline. Due to the low proportion of difficult instructions in the previous instruction-following test dataset, we manually created a new difficulty-balanced test dataset, named WizardEval. We evaluate Alpaca, Vicuna, ChatGPT, and WizardLM on a wide range of LLM benchmarks (covering reasoning, code, mathematics, general conversation, etc.). Our main findings are as follows:
+
+• We introduce Evol-Instruct, a novel approach that enhances the performance of the opensource LLMs by a large margin via automatically mass-producing open-domain instructions of various topics and difficulty levels.   
+• We develop WizardLM model, which significantly surpasses typical open-source LLMs such as Alpaca and Vicuna in a series of benchmarks. Notably, WizardLM outperforms baselines by a substantial margin in terms of code, math, GPT-4 and human evaluations.   
+• We have undertaken a preliminary investigation that underscores the importance of instruction complexity in attaining outstanding performance in supervised fine-tuning large pre-trained language models.
+
+# 2 RELATED WORK
+
+Closed domain instruction tuning Early instruction-following training work (Wei et al., 2021; Longpre et al., 2023) concerns cross task generalization in LMs, where LMs are fine-tuned on a broad range of public NLP datasets and evaluated on a different set of NLP tasks. T5 Raffel et al. (2020) made the earliest attempt by training natural language processing (NLP) tasks such as question answering, document summarization, and sentiment classification together using a unified text-to-text format. Works such as FLAN Wei et al. (2021), ExT5 Aribandi et al. (2022), T0 Sanh et al. (2022), and KnowDA Wang et al. (2022c) increased the number of NLP tasks to around one hundred, with several instructions carefully designed for each task de Wynter et al. (2023); Svikhnushina & Pu (2023); Huang et al. (2023); Yue et al. (2023). Furthermore, works such as ZeroPrompt Xu et al. (2022) and FLAN-T5 Chung et al. (2022) raised the number of tasks to the thousands. These studies consistently show that fine-tuning LMs with diverse NLP task instructions enhances their performance on new tasks. However, LLMs trained with these closed-form instructions (i.e., instructions are often only for a single NLP task, and the input data form is simple) tend to fail in real-world user scenarios.
+
+Open domain instruction tuning Our work belongs to this research line. OpenAI has hired many annotators and written many instructions with corresponding correct responses. These humancreated instructions have diverse forms and rich task types. Based on this dataset, OpenAI trained GPT-3 Brown et al. (2020) into InstructGPT Ouyang et al. (2022), which can process a variety of real user instructions and led to the success of ChatGPT. Orca Mukherjee et al. (2023) learns not only the superficial response text from LLMs, but also captures complex reasoning process signals. Since these outstanding works from OpenAI were not open-sourced, Alpaca Taori et al. (2023) and Vicuna Chiang et al. (2023) subsequently actively explored open-domain instruction fine-tuning based on the open-source LLM LLaMA Touvron et al. (2023). Alpaca used a dataset of $5 0 \mathrm { k }$ instructions generated from a limited (e.g., 175 samples) seed set of manually-written instructions. Our work is different from InstructGPT and Vicuna in that we use AI-generated data for instruction fine-tuning. Unlike Alpaca’s self-instruct Wang et al. (2022a) generation method, Evol-Instruct can control the difficulty and complexity level of the generated instructions.
+
+# 3 APPROACH
+
+In this section, we elaborate on the details of the proposed Evol-Instruct. As illustrated in Figure 2, the pipeline mainly contains two components: Instruction Evolver and Instruction Eliminator. The

+Figure 2: Overview of Evol-Instruct
+
+details of these compoents will be presented in Sec. 3.2 and instruction fine-tuning method will be described in Sec. 3.3.
+
+# 3.1 DEFINITION OF INSTRUCTION DATA EVOLUTION
+
+We start the evolution from a given initial instruction dataset $D ^ { ( 0 ) } = ( I _ { k } ^ { ( 0 ) } , R _ { k } ^ { ( 0 ) } ) _ { 1 \leq k \leq N }$ , where $I _ { k } ^ { ( 0 ) }$ is the $k$ -th instruction in $D ^ { ( 0 ) }$ , $R _ { k } ^ { ( 0 ) }$ is the corresponding response for the $k$ -th instruction, and $N$ is the number of samples in $D ^ { ( 0 ) }$ . In each evolution, we upgrade all the $I ^ { ( t ) }$ in $D ^ { ( t ) }$ to $I ^ { ( t + 1 ) }$ by prompting a LLM with Evol-Instruct prompt, and then use the LLM to generate corresponding responses $\mathbf { \mathring { R } } ^ { t + \mathbf { \check { 1 } } }$ for the newly evolved $I ^ { t + \bar { 1 } }$ . Thus, we obtain an evolved instruction dataset $D ^ { t + \bar { 1 } }$ . By iteratively performing $M$ evolutions, we can sequentially obtain $M$ evolution datasets $[ D ^ { ( 1 ) } \cdots { \dot { D } } ^ { ( M ) } ]$ . Our work focuses on open-domain instruction data, where instructions have varying inputs and tasks without a clear distinction between the instruction part and the input.
+
+# 3.2 AUTOMATIC INSTRUCTION DATA EVOLUTION
+
+Our pipeline for instruction evolution consists of three steps: 1) instruction evolving, 2) response generation, and 3) elimination evolving, i.e., filtering intructions that fails to evolve.
+
+Instruction Evolution. We found that LLMs can make given instructions more complex and difficult using specific prompts. Additionally, they can generate entirely new instructions that are equally complex but completely different. Using this discovery, we can iteratively evolve an initial instruction dataset, improving difficulty level and expanding its richness and diversity. We initiate the instruction pool with the given initial instruction dataset $\bar { \boldsymbol D } ^ { ( 0 ) }$ . In each evolution epoch, upgraded instructions from the previous epoch are taken out from the pool. Then we leverage the instruction evolver to evolve each fetched instruction, and the instruction eliminator to check whether the evolution fails. Successful evolved instructions are added to the pool, while unsuccessful ones are placed back as they are, with the hope of upgrading them successfully in the next evolution epoch.
+
+Instruction Evolver. The Instruction Evolver is an LLM that uses Evol-Instruct prompts to evolve instructions, with two types: in-depth evolving and in-breadth evolving.
+
+In-Depth Evolving enhances instructions by making them more complex and difficult through five types of prompts: add constraints, deepening, concretizing, increased reasoning steps, and complicating input. The core part of In-Depth Evolving’s prompt is ”Your objective is to rewrite a given prompt into a more complex version to make those famous AI systems (e.g., ChatGPT and GPT4 (OpenAI, 2023)) a bit harder to handle. But the rewritten prompt must be reasonable, understood, and responded to by humans”. We require the LLM to create challenging instructions that are reasonable and not arbitrarily imagined by AI. A gradual difficulty increase is necessary to avoid filling the instruction set with extremely complex instructions, which would harm the generalization performance of trained models. To control difficulty increase, we make each evolution ”a bit harder” and restrict adding a maximum of 10 to 20 words. Among the five mentioned evolving, all can be implemented without any in-context examples except for complicating input. We show the prompt of add constraints as follows (the prompts of deepening, concretizing and increased reasoning steps will be detailed in the Appendix A-C).
+
+# Example 3.1: Prompt for Adding Constraints of In-Depth Evolving
+
+I want you act as a Prompt Rewriter.   
+Your objective is to rewrite a given prompt into a more complex version to make those famous AI systems (e.g., ChatGPT and GPT4) a bit harder to handle. But the rewritten prompt must be reasonable and must be understood and responded by humans.   
+Your rewriting cannot omit the non-text parts such as the table and code in #Given Prompt#:. Also, please do not omit the input in #Given Prompt#.   
+You SHOULD complicate the given prompt using the following method:   
+Please add one more constraints/requirements into #Given Prompt#
+
+You should try your best not to make the #Rewritten Prompt# become verbose, #Rewritten Prompt# can only add 10 to 20 words into #Given Prompt#. ‘#Given Prompt#’, ‘#Rewritten Prompt#’, ‘given prompt’ and ‘rewritten prompt’ are not allowed to appear in #Rewritten Prompt#
+
+#Given Prompt#: {Here is instruction.} #Rewritten Prompt#:
+
+For complicating input, we will use in-context demonstration. Due to the lengthy demonstrations, we will provide a brief template below, with the full prompt detailed in the Appendix D.
+
+# Example 3.2: Prompt for Complicating Input of In-Depth Evolving
+
+I want you act as a Prompt Rewriter.
+
+Your objective is to rewrite a given prompt into a more complex version to make those famous AI systems (e.g., ChatGPT and GPT4) a bit harder to handle. But the rewritten prompt must be reasonable and must be understood and responded by humans.
+
+You must add [XML data] format data as input data in [Rewritten Prompt]   
+#Given Prompt#:   
+{Here is instruction of Example 1.}   
+#Rewritten Prompt#:   
+{Here is rewritten instruction of Example 1.}
+
+... N -1 Examples ...
+
+You must add [#Given Dataformat#] format data as input data in [Rewritten Prompt]   
+#Given Prompt#:   
+{Here is instruction of Example N.}   
+#Rewritten Prompt#:
+
+In-Breadth Evolving aims to enhance topic coverage, skill coverage, and overall dataset diversity. Open-domain instruction finetune datasets (e.g., Alpaca, ShareGPT, etc.) are typically small in scale, lacking topic and skill diversity. To solve this problem, we designed a prompt to generate a completely new instruction based on the given instruction, requiring the new instruction to be more long-tailed. Our In-Breadth Evolving prompt is as follows:
+
+# Example 3.3: Prompt for In-Breadth Evolving
+
+I want you act as a Prompt Creator.   
+Your goal is to draw inspiration from the #Given Prompt# to create a brand new prompt.   
+This new prompt should belong to the same domain as the #Given Prompt# but be even more rare.   
+The LENGTH and difficulty level of the #Created Prompt# should be similar to that of the #Given Prompt#.   
+The #Created Prompt# must be reasonable and must be understood and responded by humans.
+
+‘#Given Prompt#’, ‘#Created Prompt#’, ‘given prompt’ and ‘created prompt’ are not allowed to appear in #Created Prompt#.
+
+#Given Prompt#: {Here is instruction.} #Created Prompt#:
+
+Response Generation. We use the same LLM as for evolving to generate the corresponding responses for the evolved instructions. The generation prompt is “{Here is instruction. $\} ^ { , , }$ , we feed it into the request of the ChatGPT-3.5 and parse the returned text body as the response.
+
+Elimination Evolving. We classify the following four situations as instruction evolution failure:
+
+1. The evolved instruction does not provide any information gain compared to the original one. We use ChatGPT to make this determination, details please refer to Appendix G.   
+2. The evolved instruction makes it difficult for the LLM to generate a response. We found that when the generated response contains “sorry” and is relatively short in length (i.e., less than 80 words), it often indicates that the LLM struggles to respond to the evolved instruction. So we can use this rule to make a judgment.   
+3. The response generated by the LLM only contains punctuation and stop words.   
+4. The evolved instruction obviously copies some words from the evolving prompt, such as “given prompt”, “rewritten prompt”, “#Rewritten Prompt#”, etc.
+
+# 3.3 FINETUNING THE LLM ON THE EVOLVED INSTRUCTIONS
+
+Once all evolutions are done, we will merge the initial instruction dataset with evolved instruction data from all epochs and randomly shuffle the samples to create the fine-tuning dataset. This processing ensures even distribution of instructions of varying difficulty levels in the dataset, maximizing model fine-tuning smoothness. To prove that the performance gain is not due to the increased amount of data after merging, but from our proposed novel method Evol-Instruct, we randomly sample an equal amount of data the same with training baselines (e.g., Vicuna) from this merged data as our final fine-tuning data. We choose Vicuna’s prompt as the prompt for our fine-tuning, the specific format is “A chat between a curious user and an artificial intelligence assistant. The assistant gives helpful, detailed, and polite answers to the user’s questions. USER: Hi ASSISTANT: Hello. USER: Who are you? ASSISTANT: I am WizardLM .
+
+# 4 EXPERIMENT
+
+We assess WizardLM, Alpaca, Vicuna, and ChatGPT using both automatic and human evaluations.
+
+# 4.1 BASELINES
+
+(1) ChatGPT is an AI chatbot developed by OpenAI that can interact with users in a natural and engaging way. It is built on top of LLMs like GPT-3.5 and GPT-4, trained on vast internet text data.
+
+(2) Alpaca is an open-source instruction-following model developed by Stanford University. For a fair comparison, we expanded the number of instructions from $5 2 k$ to $7 0 k$ using self-Instruct adopted by Alpaca and replaced the original Davici-003 responses with ChatGPT’s responses. We re-trained Alpaca 13B from LLaMA 13B(Touvron et al., 2023) based on this new Alpaca data.
+
+(3) Vicuna is based on LLaMA and fine-tuned on $7 0 k$ user-shared conversations collected from ShareGPT. It is one of the most advanced and versatile open instruction-following models available today. We use the 13B-v1.1 model from FastChat 4.
+
+(4) Open-source models trained from Llama 13B, including Baize (Xu et al., 2023), CAMEL (Li et al., 2023a), and Tulu (Wang et al., 2023)
+
+# 4.2 EXPERIMENT DETAIL
+
+To construct the dataset, we initialize it with the $5 2 k$ instruction dataset of Alpaca and iteratively perform $M$ evolutions, where $M = 4$ . For each instruction in each round of evolution, we randomly select one evolving prompt from total six prompts (i.e., five from in-depth evolving and one from in-breadth evolving) with equal probability. We execute above process using Azure OpenAI ChatGPT $\mathsf { A P I } ^ { 5 }$ . Then, we leverage ChatGPT to generate responses. Finally, we obtain $2 5 0 k$ instructions. For a fair comparison, we randomly sample $7 0 k$ data from $2 5 0 k$ data with equal probability as the final training data for WizardLM, the same as the amount of training data for Vicuna. We use a temperature of 1 to generate response and set the maximum number of tokens for generation to 2048. Additionally, we set the frequency penalty to zero and top- $\mathrm { \bf p }$ to 0.9. Totally, we request the API $5 2 k$ $\times ~ 4 \times 3 = 6 2 4 k$ times to construct the full dataset. We use pre-trained LLaMA 13B (Touvron et al., 2023) to initialize our model. We adopt Adam optimizer with an initial learning rate of $2 \times 1 0 ^ { - 5 }$ , a maximum number of tokens 2048, and the batch size is 4 for each GPU. We train our model on 8 V100 GPUs with Deepspeed Zero-3 for 140 hours on 3 epochs. For inference, we use greedy search for WizardLM and baseline models, and set the maximum generation length to 2048.
+
+# 4.3 AUTOMATIC EVALUATION
+
+To present a comprehensive overview of the performance of our WizardLM, we conduct a comparative comparison between our model and the established baselines across a range of LLM benchmarks.
+
+OpenLLM Leaderboard of HuggingFace (Beeching et al., 2023) includes MMLU (Hendrycks et al., 2020), ARC (Clark et al., 2018), HellaSwag (Zellers et al., 2019), and TruthfulQA (Lin et al., 2022). MMLU consists of a range of multiple-choice academic questions. ARC is a set of grade-school science questions. HellaSwag is a test of commonsense inference. TruthfulQA measures a model’s propensity to reproduce falsehoods. We adopt the evaluate code (Gao et al., 2021) from OpenLLM.
+
+Code Generation We use the extensively utilized HumanEval (Chen et al., 2021) benchmark consisting of 164 coding problems to evaluate LLMs’ code writing capabilities at the function level by reporting the pass $@ 1$ metric.

+
+As shown in Figure 3 and Table 1, compared with other same-sized open-sourced models, WizardLM has a remarkable performance advantage in most benchmarks. Especially in math, code, and GPT-4 evaluations, it achieves significant improvement over Alpaca, Vicuna, Baize, CAMEL, and Tulu.

+
+# 4.4 HUMAN EVALUATION
+
+To evaluate WizardLM, we conduct human evaluation on our crafted testbed WizardEval, which includes 218 real-world human instructions from diverse sources such as online opensource projects (Github, ShareGPT), platforms (Twitter), and forums (Reddit, Discord). The data contains 29 skills and domains that represent the main requirements of humanity, such as Coding Generation, Math, Reasoning, Complex Formats, Writing, Extensive Disciplines, and so on. As shown in Figure 4a and Appandix Figure 6, we also analyse the difficulty and skills distribution of WizardEval respectively, which indicate that WizadEval is able to handle the evaluation on more complex and demanding scenarios than Self-Instruct and Vicuna testset.
+
+We perform a blind pairwise comparison between WizardLM-13b and baselines. Specifically, we recruit 10 well-educated annotators. To each annotator, four responses from Alpaca-13b, Vicuna-13b, WizardLM and ChatGPT are presented, which are randomly shuffled to hide their sources. The annotators then judge which response is better following criterion (for detailed definition, please refer to Appendix K): (1) Relevance, (2) Knowledgeable, (3) Reasoning, (4) Calculation, and (5) Accuracy.
+
+Then they should rank the four responses from 1 to 5 (1 means best), and allowing equal scores for comparable instances. To estimate the win rate, we compare the frequency of win, lost, and tie between each pair of models. As shown in Figure 4 (b). WizardLM achieved significantly better results than Alpaca and Vicuna, which demonstrates the effectiveness of Evol-Instruct method. All of the Kappa scores are greater than 0.6, which indicates the good agreement among the annotators.

In order to study the impact of different data seeds, Evol models, scale of evolved dataset, pre-trained models on our proposed method, we conducted the following experiments: a) Using 70k ShareGPT as the seed data to obtain WizardLM-13b (ShareGPT Seed); b) Using LlaMA-2-70B-Chat to replace ChatGPT as the evolutionary execution model to obtain WizardLM-13b (LlaMA-2-70B-Chat Evol); c) We train on larger size pre-trained models Llama-1 65B and Llama-2 70B to obtain WizardLM-65b and WizardLM-70b respectively; d) Using the complete $2 5 0 \mathrm { k }$ evolved data to obtain WizardLM13b (250K); e) Using a completely different base from the LlaMA family, Mistral-7B, to obtain WizardLM-7b (Mistral); f) In order to compare more diverse instruction data, we choose Supernatural Instructions(Wang et al., 2022b) and randomly extract 70k data to train llama-13b to obtain LlaMA13b (SNI). The full results are shown in the Table 2. To investigate the reason of why does WizardLM13b (ShareGPT Seed) performs worse on GSM8k, we random sample 2000 instructions from ShareGPT and Alpaca data respectively, then use ChatGPT to judge (prompt please refer to Appendix G) whether an instruction is “math” related, we find that the ShareGPT only contains $4 . 3 \%$ math data, and Alpaca data contains $1 1 . 8 \%$ math data, thus we think that less math data results in worse GSM8k performance of WizardLM-13b (ShareGPT Seed).
+
+The results indicate that (i) the ShareGPT is a better seed for evol-instruct than Alpaca, (ii) larger evolved data size can improve model capacity, and (iii) our proposed Evol-Instruct method is not dependent on ChatGPT, other strong open source model such as Llama-2 is also a good substitute for

+(b) Average score on automatic benchmarks
+
+ChatGPT, (iv) our evloved data also shows better finetune performance than Supernatural Instructions. Futhermore, the results on different pre-trained bases (e.g., Llama-1 65B, Llama-2, Mistral-7B) indicate that our Evol-Instruct can be widely applied to various pre-trained models.
+
+Analysis of In-depth Evolving. The Figure 5a and 5b presents an ablation study investigating the impact of the number of data evolution rounds. To study the depth of the evolving process, we use ChatGPT to judge the difficulty level of instruction. The used prompt please refer to Appendix E.
+
+Figure 5b shows the average scores (on nine automatic benchmarks in Section 4.3) of the models fine-tuned with the data from each evolution round. Each round of data from $C 0$ to $C 4$ is about $5 2 k$ . From the trend of this figure, it can be seen that as the complexity of the training instruction data gradually increases, the performance of the fine-tuned models also improves synchronously. To investigate the correctness of the difficulty score by ChatGPT, we also use GPT-4 and human to measure the instructions difficulty, the detailed results in the Table 3 of Appendix I indicate the good agreement among the ChatGPT, GPT-4 and human annotators.
+
+Analysis of In-breadth Evolving. We aims to examine the semantic breadth of instructions. We use t-SNE van der Maaten & Hinton (2008) and the $\mathbf { k }$ -means Hartigan & Wong (1979) algorithm to partition instructions BERT embeddings into 20 clusters. Figure 6 in Appendix F displays clusters, highlighting our method’s superior dispersion compared to ShareGPT and Alpaca, indicating greater topic diversity in our instructions.
+
+# 5 CONCLUSIONS
+
+This paper presented Evol-Instruct, an evolutionary algorithm that generates diverse and complex instruction data for LLM. Comprehensive experiments demonstrate that WizardLM significantly surpasses typical open-source LLMs such as Alpaca and Vicuna in a wide range of well-recognized benchmarks. Notably, WizardLM outperforms baselines by a substantial margin in terms of code, math, GPT-4 and human evaluations.
+
+Limitations. This paper acknowledges the limitations of our automatic GPT-4 and human evaluation methods. This method poses challenges for scalability and reliability. Moreover, our test set may not represent all the scenarios or domains where LLM can be applied or compared with other methods.

+
+# H WIZARDEVAL ANALYSIS
+
+We collected our Evol-Instruct testset that includes real-world human instructions from diverse sources such as online opensource projects, platforms, and forums. We analyzed the data and identified 29 distinct skills that represent the main requirements of humanity, such as Coding Generation $\&$ Debugging, Math, Reasoning, Complex Formats, Writing, Extensive Disciplines, and so on. Figure 6 illustrates the distribution of the instances and skills in our test set. Our test set consists of 218 instances, each of which is an instruction for a specific skill. We compared our test set with Vicuna’s test set, which is a benchmark dataset for evaluating instruction following models. We found that Vicuna’s test set only 80 instances and 9 skills and is much smaller and less diverse than ours. Figure 4a shows how the difficulty and complexity of the test data vary across different instances. Our test data has a more uniform distribution, meaning that it contains instructions with different levels of difficulty and complexity. On the other hand, Vicuna and Alpaca have a skewed distribution, meaning that they mostly contain instructions with low difficulty and complexity. This indicates that these two corpus are not able to handle the evaluation on more complex and demanding scenarios.

+# I DIFFERENT DIFFICULTY ANNOTATORS
+
+We just use the ChatGPT to post analyse the“difficult” distribution of the generated instructions, but we do not use this analysis results to guide the data generation or model training. In order to explore the ability of ChatGPT to perform difficulty analysis, we sample 600 instructions and use the more powerful GPT4 model and 5 well-educated human annotators together for difficulty assessment. The assessment results are in the Table 3. The results show that ChatGPT, GPT4, and manual annotation show a high degree of consistency in the trend of difficulty changes.
+
+<table><tr><td></td><td>ShareGPT</td><td>Alpaca</td><td>C1</td><td>C2</td><td>C3</td><td>C4</td></tr><tr><td>GPT-3.5</td><td>4.63</td><td>3.00</td><td>5.48</td><td>6.35</td><td>6.84</td><td>7.08</td></tr><tr><td>GPT-4</td><td>4.31</td><td>2.69</td><td>4.68</td><td>4.90</td><td>5.37</td><td>5.54</td></tr><tr><td>Human</td><td>4.55</td><td>3.15</td><td>5.51</td><td>5.86</td><td>6.49</td><td>6.82</td></tr></table>
+
+Table 3: Use ChatGPT, GPT-4, human to measure the instruction difficulty.
+
+To investigate the correctness of the difficulty score by ChatGPT, we add a new experiment to measure agreement of difficulty judge between ChatGPT and humans: We randomly select two instructions from the six datasets - Alpaca, ShareGPT, C1 to C4 - with equal probability each time, forming a pair. In total, we have selected 300 instruction pairs. Then, we ask ChatGPT and 5 well-educated human annotators to judge which one is more difficulty in one instruction pair, the Kappa score between humans is 0.68, and the Kappa between ChatGPT and human (majority voting) is 0.66, which indicates the good agreement among the ChatGPT and human annotators.
+
+# J CLUSTER SCATTER PLOT
+
+In-breadth Evolving aims to enhance topic coverage, skill coverage, and overall dataset diversity. To examine (qualitative analysis) the breadth (diversity) of different dataset, we firstly use BERT to encode each instruction and get its embedding with 768 dimensions, then use a dimension reduction algorithm named t-SNE to reduce embedding dimension to 2, finally we apply a clustering algorithm $\mathbf { k }$ -means to partition the instructions of each dataset into 20 clusters for an intuitive visualization. As shown in the Figure 7, the data points of our dataset are more dispersed than ShareGPT and Alpaca (Self-Instruct), which indicates the better topic diversity in our instructions.

+Figure 7: The cluster scatter plot between ShareGPT, Alpaca, and ours four rounds of instruction evolution from C1 to C4. The number of cluster centers is 20.
+
+# K HUMAN EVALUATION ASPECTS
+
+The annotators then judge which response is better from five aspects:
+
+(1) Relevance: Assessing the model’s ability to correctly interpret the semantic meaning of the context and questions.   
+(2) Knowledgeable: Whether the model can accurately use various and detailed knowledge for problem-solving.   
+(3) Reasoning: Assessing the model’s ability to execute correct reasoning processes or devise valid reasoning concepts to solve problems.   
+(4) Calculation: Evaluating whether the model can perform accurate mathematical computations of the provided formulas in the domains of math, biology, chemistry and physics.   
+(5) Accuracy: Evaluating whether the model can perform correctly in the corresponding for a given instruction.
+
+# L PERFORMANCE DETAILS OF DIFFERENT CHECKPOINTS
+
+In this paper, we train our model with 3 epochs and only reported the performance of the final checkpoint in the above “Section 4 Experiment” to align with previous works.
+
+As shown in the following Table 4, we report the model checkpoints performance on different epochs (2.5, 2,75, 3). For 13B models, we can see that the best performance always appears on WizardLM13b (ShareGPT Seed) for each benchmark except GSM8k. And for 65b/70b models, we also see that the WizardLM-70b is the best one on all the benchmarks. Therefore, we think this is mainly caused by the fluctuations on some benchmarks in model training.

In this paper, we show an avenue for creating large amounts of instruction data with varying levels of complexity using LLM instead of humans. Starting with an initial set of instructions, we use our proposed Evol-Instruct to rewrite them step by step into more complex instructions. Then, we mix all generated instruction data to fine-tune LLaMA. We call the resulting model WizardLM. Both automatic and human evaluations consistently indicate that WizardLM outperforms baselines such as Alpaca (trained from SelfInstruct) and Vicuna (trained from human-created instructions).

Initial attempts (Aribandi et al., 2022; Wei et al., 2021; Xu et al., 2022; Sanh et al., 2022; Chung et al., 2022) to train instruction-following language models are based on a collection of various NLP tasks, with a small amount of hand-written instructions. These closed-domain instructions suffer from two main drawbacks: first, all the samples in an NLP dataset share only a few common instructions, severely limiting their diversity; second, the instructions usually only ask for one task. But in real life, human instructions often have multiple and varied task demands. By using open-domain instruction data generated by real human users, OpenAI’s LLMs (e.g., InstructGPT (Ouyang et al., 2022) and ChatGPT 1) have achieved great success. These open-domain instructions can fully unleash the unlimited potential of LLMs (Luo et al., 2023; Ma et al., 2023; Hu et al., 2023; Zhu et al., 2023) and enable them to perform more complex and diverse tasks. However, using humans to create open-domain instruction datasets like OpenAI did will encounter the following challenges. The whole annotating process is extremely expensive and time-consuming (Kopf et al., 2023; Chen et al., 2023; Sun et al., 2023; Yuan et al., 2023). On the other hand, the difficulty level distribution of humancreated instructions is skewed towards being easy or moderate, with fewer difficult ones (according to the difficulty statistics of ShareGPT (Chiang et al., 2023) from Figure 5a). Human annotators are prone to fatigue and cannot sustain high-intensity work to produce a sufficient proportion of high-difficulty instructions (Zhang et al., 2023; Xiao et al., 2023; Manakul et al., 2023; Zhong et al., 2023). Based on these issues, developing an automatic method that can mass-produce open-domain instructions (especially the more difficult ones) at a relatively low cost becomes the key to further advancing instruction-tuned language models (Bao et al., 2023; Liu et al., 2023; Bian et al., 2023; Cabannes et al., 2023).

The In-depth Evolving includes five types of operations: add constraints, deepening, concretizing, increase reasoning steps, and complicate input. The In-breadth Evolving is mutation, i.e., generating a completely new instruction based on the given instruction. These six operations are implemented by prompting an LLM with specific prompts. Since the evolved instructions are generated from LLMs, sometimes the evolving will fail. We adopt an instruction eliminator to filter the failed instructions, which is called Elimination Evolving.

Alpaca data has a total of $5 2 k$ samples and is generated using self-instruct (Wang et al., 2022a) from only 175 human-created seed instructions. We choose Alpaca data as the initial data for evolution, which can ensure that the training instructions of WizardLM have almost no direct human participation in annotations. We execute four epochs of evolution using OpenAI ChatGPT $\\mathrm { \\ A P I ^ { 2 } }$ and finally obtain $2 5 0 k$ instructions. To ensure a fair comparison with Vicuna’s $7 0 k$ real user data, we sampled $7 0 k$ from the full $2 5 0 k$ data and fine-tuned the LLaMA 13B model. Because the original Alpaca data only has $5 2 k$ samples, we used its self-instruct method to generate an additional $1 8 k$ data, and retrained the LLaMA 13B model with its code3 to get Alpaca 13B as our baseline. Due to the low proportion of difficult instructions in the previous instruction-following test dataset, we manually created a new difficulty-balanced test dataset, named WizardEval.

T5 Raffel et al. (2020) made the earliest attempt by training natural language processing (NLP) tasks such as question answering, document summarization, and sentiment classification together using a unified text-to-text format. Works such as FLAN Wei et al. (2021), ExT5 Aribandi et al. (2022), T0 Sanh et al. (2022), and KnowDA Wang et al. (2022c) increased the number of NLP tasks to around one hundred, with several instructions carefully designed for each task de Wynter et al. (2023); Svikhnushina & Pu (2023); Huang et al. (2023); Yue et al. (2023). Furthermore, works such as ZeroPrompt Xu et al. (2022) and FLAN-T5 Chung et al. (2022) raised the number of tasks to the thousands. These studies consistently show that fine-tuning LMs with diverse NLP task instructions enhances their performance on new tasks. However, LLMs trained with these closed-form instructions (i.e., instructions are often only for a single NLP task, and the input data form is simple) tend to fail in real-world user scenarios. ",

(2022), which can process a variety of real user instructions and led to the success of ChatGPT. Orca Mukherjee et al. (2023) learns not only the superficial response text from LLMs, but also captures complex reasoning process signals. Since these outstanding works from OpenAI were not open-sourced, Alpaca Taori et al. (2023) and Vicuna Chiang et al. (2023) subsequently actively explored open-domain instruction fine-tuning based on the open-source LLM LLaMA Touvron et al. (2023). Alpaca used a dataset of $5 0 \\mathrm { k }$ instructions generated from a limited (e.g., 175 samples) seed set of manually-written instructions. Our work is different from InstructGPT and Vicuna in that we use AI-generated data for instruction fine-tuning. Unlike Alpaca’s self-instruct Wang et al.

+# ABSTRACT
+
+In this work, we address challenging multi-agent cooperation problems with decentralized control, raw sensory observations, costly communication, and multiobjective tasks instantiated in various embodied environments. While previous research either presupposes a cost-free communication channel or relies on a centralized controller with shared observations, we harness the commonsense knowledge, reasoning ability, language comprehension, and text generation prowess of LLMs and seamlessly incorporate them into a cognitive-inspired modular framework that integrates with perception, memory, and execution. Thus building a Cooperative Embodied Language Agent CoELA, who can plan, communicate, and cooperate with others to accomplish long-horizon tasks efficiently. Our experiments on CWAH and TDW-MAT demonstrate that CoELA driven by GPT-4 can surpass strong planning-based methods and exhibit emergent effective communication. Though current Open LMs like LLAMA-2 still underperform, we fine-tune a CoLLAMA with data collected with our agents and show how they can achieve promising performance. We also conducted a user study for human-agent interaction and discovered that CoELA communicating in natural language can earn more trust and cooperate more effectively with humans. Our research underscores the potential of LLMs for future research in multi-agent cooperation. Videos can be found on the project website https://vis-www.cs.umass.edu/Co-LLM-Agents/.
+
+# 1 INTRODUCTION
+
+Humans are adept at cooperating and communicating with others when solving complex tasks (Woolley et al., 2010). Building embodied agents that can also engage in and assist humans in everyday life is a valuable but challenging task, considering the complexity of perception, partial observation, long-horizon planning, natural language communication, and so on (Deitke et al., 2022).
+
+Large Language Models (LLMs) have exhibited remarkable capabilities across various domains, implying their mastery of natural language understanding, dialogue generation, rich world knowledge, and complex reasoning capability (OpenAI, 2023; Touvron et al., 2023; Brown et al., 2020; Bubeck et al., 2023). Recent research has also demonstrated that LLMs can drive embodied agents for single-agent tasks through zero-shot prompting for instruction following tasks (Huang et al., 2022a) or few-shot prompting for more complex long-horizon tasks (Song et al., 2022). However, building cooperative embodied agents to work with other agents or with humans under decentralized settings with costly communication remains challenging and rarely explored, where they also need to have strong abilities for cooperative planning and efficient communication. To date, it still remains unclear whether LLMs have such abilities necessary for distributed embodied multi-agent cooperation.
+
+Therefore, this paper aims to investigate how to leverage LLMs to build cooperative embodied agents that can collaborate and efficiently communicate with other agents and humans to accomplish longhorizon multi-objective tasks in a challenging decentralized setting with costly communication. To this end, we focus on an embodied multi-agent setting as shown in Figure 1, where two decentralized embodied agents have to cooperate to finish a multi-objective household task efficiently with complex partial observation given. Specifically, communication in our setting takes time as in real life, so the agents can’t simply keep free talking with each other. To succeed in this setting, agents must i) perceive the observation to extract useful information, ii) maintain their memory about the world, the task, and the others, iii) decide what and when to communicate for the best efficiency and iv) plan collaboratively to reach the common goal.

+Figure 1: A challenging multi-agent cooperation problem with decentralized control, raw sensory observations, costly communication, and long-horizon multi-objective tasks.
+
+Inspired by prior work in cognitive architectures (Laird, 2019), we present CoELA, a Cooperative Embodied Language Agent, a cognitive architecture with a novel modular framework that utilizes the rich world knowledge, strong reasoning ability and mastery natural language understanding and generation capability of LLMs, who plan and communicate with others to cooperatively solve complex embodied tasks. Our framework consists of five modules, each to address a critical aspect of successful multi-agent cooperation, including a Perception Module to perceive the observation and extract useful information, a Memory Module mimicking human’s long-term memory to maintain the agent’s understanding of both the physical environment and other agents, a Communication Module to decide what to communicate utilizing the strong dialogue generation and understanding capability of LLMs, a Planning Module to decide high-level plans including when to communicate considering all the information available, and an Execution Module to execute the plan by generating primitive actions using procedures stored in the memory module.
+
+We instantiate our challenging setting and evaluate our framework on two embodied environments: ThreeDWorld Multi-Agent Transport (TDW-MAT) and Communicative Watch-And-Help (C-WAH). Our experimental results indicate that CoELA can perceive complex observations, reason about the world and others’ state, communicate efficiently, and make long-horizon plans accordingly, as showcased in Figure 1 where CoELA divide the labor with its partner through natural language communication effectively. In particular, CoELA driven by GPT-4 can outperform strong planningbased baselines by achieving more than $40 \%$ efficiency improvements and exhibiting emergent efficient communication. Though Open LMs like LLAMA-2 still underperform, we utilize parameterefficient fine-tuning techniques LoRA (Hu et al., 2021) to train a CoLLAMA on few data collected with our agents and gain promising performance. In the user study, we also discover that CoELA communicating with humans in natural language can earn more trust. Our contribution includes:

+# 2 RELATED WORK
+
+Multi-Agent Cooperation and Communication The field of multi-agent cooperation and communication has a long-standing history (Stone & Veloso, 2000). Many platforms have been proposed for various multi-agent tasks (Lowe et al., 2017; Resnick et al., 2018; Shu & Tian, 2018; Jaderberg et al., 2019; Samvelyan et al., 2019; Suarez et al., 2019; Baker et al., 2019; Bard et al., 2020). Other works focused on methods that improves communication efficiency (Jiang & Lu, 2018; Das et al., 2019; Wang et al., 2021; Wan et al., 2022), cooperation in visually rich domains (Jain et al., 2020), or grounding communications in environments (Patel et al., 2021; Mandi et al., 2023; Narayan-Chen et al., 2019). For embodied intelligence, Puig et al. (2021; 2023) explored the social perception of the agents during their cooperation. However, these platforms either neglects communication (Jaderberg et al., 2019; Samvelyan et al., 2019; Carroll et al., 2019; Puig et al., 2021; 2023), or use uninterpretable continuous vectors (Jiang & Lu, 2018; Das et al., 2019) or limited discrete symbols (Lowe et al., 2017; Jaques et al., 2019; Jain et al., 2020; Patel et al., 2021; Resnick et al., 2018) for communication. In contrast, we propose a more challenging setting where no presupposed free communication channel exists, and distributed agents need to use natural language to communicate efficiently with others, especially humans.
+
+Language Agents Recently, numerous studies have explored language agents which use LLMs for sequential decision-making (Yang et al., 2023; Wang et al., 2023b; Xi et al., 2023; Sumers et al., 2023). Although LLMs still face challenges when solving complex reasoning problems (Bubeck et al., 2023), a substantial body of work demonstrates their capacity to make plans (Sharma et al., 2021; Raman et al., 2022; Pallagani et al., 2022; Gramopadhye & Szafir, 2022; Yuan et al., 2023; Li et al., 2022; Wang et al., 2023d), especially in embodied environments (Li et al., 2023a; Padmakumar et al., 2022; Kolve et al., 2017; Shridhar et al., 2020; Misra et al., 2018; Zhu et al., 2017; Brodeur et al., 2017; Xia et al., 2018; Savva et al., 2019; Xiang et al., 2020; Jain et al., 2020; 2019). Specifically, Liang et al. (2022); Song et al. (2022) used codes or few-shot prompting to directly generate plans, Huang et al. (2022b) built an inner monologue with environment feedback to improve planning, Ahn et al. (2022) combined robotic affordances and LLMs for grounded instruction following. There has also been a line of work utilizing multiple LLMs to cooperate or debate with each other "in mind" to strengthen the single agent’s capability to solve complex tasks (Li et al., 2023b; Du et al., 2023; Wang et al., 2023c), different from their "free self-talk" setting, our decentralized language agents must plan about when and what to communicate carefully since it’s costly in real-life. More recently, Park et al. (2023) built an agent society using LLMs augmented with memories to simulate human behavior. In contrast to the above, our work addresses a more challenging multi-agent cooperation problem, characterized by decentralized control, complex observations, costly communication, and long-horizon multi-objective tasks. We also study the capability of Open LMs like LLAMA-2 and tine-tune a CoLLAMA using LoRA with data collected by our agents in embodied environments to demonstrate their promising performance for building better cooperative embodied agents.
+
+# 3 COOPERATIVE PLANNING UNDER DEC-POMDP-COM
+
+Our setting can be defined as an extension of the decentralized partially observable Markov decision process (DEC-POMDP) (Bernstein et al., 2002; Spaan et al., 2006; Goldman & Zilberstein, 2003), which can be formalized by $( n , S , \{ \Sigma _ { i } \} , \{ A _ { i } \} , \{ O _ { i } \} , T , G , R , \gamma , h )$ , where $n$ denotes the number of agents; $S$ is a finite set of states; ${ \mathrm { \bar { } } } A _ { i } { \mathrm { \bar { } } } = { \mathrm { \bar { } } } A _ { i } ^ { W } { \mathrm { \bar { \cup } } } A _ { i } ^ { C }$ is the action set for agent $i$ , including a finite set of world actions $A _ { i } ^ { W }$ and a communication action $A _ { i } ^ { C }$ to send a message $\sigma _ { i } ~ \in ~ \Sigma _ { i }$ ; ${ \cal O } _ { i } = { \cal O } _ { i } ^ { W } \times { \cal O } _ { i } ^ { C }$ is the observation set for agent $i$ , including world observations $O _ { i } ^ { W }$ the agent receives through its sensors, and $O _ { i } ^ { C } = \Sigma _ { 1 } \times \cdots \times \Sigma _ { n }$ the set of possible messages the agent can receive from any of its teammates; $T ( s , a , s ^ { \prime } ) = p ( s ^ { \prime } | s , a )$ is the joint transition model which defines the probability that after taking joint action $a \in A _ { 1 } \times \cdots \times A _ { n }$ in $s \in S$ , the new state $s ^ { \prime } \in S$ is achieved; $\dot { G } = \{ g _ { 1 } , \cdot \cdot \cdot , g _ { k } \}$ defines the task with several sub-goals for the agents to finish; $\begin{array} { r } { R ( s , a , s ^ { \prime } ) = - c ( a ) + \textstyle \sum _ { i = 1 } ^ { k } \mathbb { 1 } ( s ^ { \prime } = g _ { i } ) - \mathbb { 1 } ( s = g _ { i } ) } \end{array}$ is the reward function to the team, where $c ( a )$ is the cost for action $a$ , and $\Im ( \cdot )$ checks if the sub-goal $g _ { i }$ is satisfied in the world state $s ; \gamma$ is the discount rate and $h$ is the planning horizon. In the remainder of this paper, we focus on noise-free broadcast communication and limit our discussion to two agents, though our methods and experiments are generalizable to more than two agents.
+
+We instantiate the problem with two decentralized intelligent embodied agents (including humans) cooperating to accomplish a long-horizon rearrangement task (Batra et al., 2020) in an indoor multiroom environment. The agents are capable of executing one of the actions from the action space $\mathcal { A } = \mathcal { A } _ { \mathrm { N A V } } \cup \mathcal { A } _ { \mathrm { I N T } } \cup \mathcal { A } _ { \mathrm { C O M } }$ , where $\mathcal { A } _ { \mathrm { N A V } }$ includes navigation actions, ${ \mathcal { A } } _ { \mathrm { I N T } }$ includes interaction actions and $\scriptstyle A _ { \mathrm { C O M } }$ includes a communication action with which the agent can send a message in natural language to broadcast to others. The rearrangement task is defined with several predicates $g _ { i }$ with counts to be satisfied, such as ON(plate,dinnertable):2 representing a sub-task of putting two plates onto the dinner table.

+Figure 2: An overview of CoELA. There are five key modules in our framework: (c) The Communication Module and (d) the Planning Module leverage LLMs to generate messages and make plans, (b) The Memory Module stores the agent’s knowledge and experience about the world and others in semantic, episodic and procedural memory respectively, (a) The Perception Module and (e) the Execution Module interact directly with the external environment by perceiving raw observations and generating primitive actions. More design details can be found in Appendix A.
+
+# 4 BUILDING COOPERATIVE EMBODIED AGENTS MODULARLY WITH LLMS
+
+# 4.1 FRAMEWORK OVERVIEW
+
+Inspired by the cognitive architectures (Langley et al., 2009; Laird, 2019; 2022), we build CoELA, a Cooperative Embodied Language Agent with novel modular framework integrating the strong reasoning ability and language generation capability of LLMs. As shown in Figure 2, CoELA consists of five key modules: (a) Perception, (b) Memory, (c) Communication, (d) Planning, and (e) Execution. At each interaction step, CoELA first uses (a) Perception Module to perceive the raw sensory observation received from the environment, then updates the (b) Memory Module with extracted new information, which stores its knowledge and experience of the world and others. CoELA tackles the challenge of efficient communication with a two-step method: first decide on what to send, then decide whether to send this message or choose another plan by deliberately using (c) The Communication Module to retrieve related information from (b) and utilize an LLM to generate the best message to send "in mind" beforehand, then leverages (d) the Planning Module driven by LLM with strong reasoning ability to make the decision on which plan to take given the related information retrieved from (b) and available actions proposed regarding the current state. The generated plan is then used to update (b2) the Episodic Memory. Finally, (e) the Execution Module retrieves procedural knowledge stored in (b3) to turn the high-level plan into primitive actions executable in the environment.
+
+# 4.2 PERCEPTION MODULE
+
+For embodied agents to be helpful in the real world, they have to perceive raw observations gained through sensors and extract useful information for downstream higher-order reasoning. We incorporate the Perception Module to deal directly with the complex visual observation received from the environment by training a Mask-RCNN (He et al., 2017) to predict the segmentation masks from the RGB image, then build 3D point clouds using the RGB-D image, extract useful high-level information such as the states of the key objects and build a local semantic map.
+
+# 4.3 MEMORY MODULE
+
+It’s of vital importance for an agent to maintain a memory of the knowledge and experience it has of the world and others, we mimic human’s long-term memory (Atkinson & Shiffrin, 1968; Wang &
+
+Laird, 2006; Nuxoll & Laird, 2012) and design Semantic memory, Episodic Memory, and Procedural Memory for CoELA.
+
+Semantic Memory stores CoELA’s knowledge about the world including a semantic map, the task progress, the state of self, and the state of others. Each time a new observation is received and perceived by the Perception Model, the Semantic Memory is updated accordingly. To be noticed, CoELA’s knowledge about the world may not be accurate since other agents may interact with the objects and change their states without its awareness. Dealing with imparities between the memory and the description of the world from others adds even more challenges.
+
+Episodic Memory stores CoELA’s experience about the past including the action history and dialogue history. Each time CoELA executes a new action including sending out a message or receiving a new message, the related information is added to the Episodic Memory.
+
+Procedural Memory contains knowledge including how to carry out specific high-level plans in a specific environment implemented in code and the neural models’ parameters.
+
+# 4.4 COMMUNICATION MODULE
+
+To deal with the what to send problem, we deliberately design a Communication Module utilizing the strong free-form language generation capability of the LLMs to act as a message generator. To better condition the LLMs on the cooperative task and avoid inefficient casual chatting, the Communication Module first retrieves the related information from the Memory Module including the semantic map, task progress, agent state, others state, and the action and dialogue history, then convert these into text descriptions using templates, finally prompt the LLMs with the concatenation of Instruction Head, Goal Description, State Description, Action History, and Dialogue History to generate the message to send. To better constrain LLMs’ generated messages, a note at the end of the prompt is added and two seed messages are appended at the beginning of the Dialogue History to elicit deserved effective communication behavior. Detailed prompt design in Appendix. A.3.
+
+# 4.5 PLANNING MODULE
+
+CoELA needs a strong Planning Module to make decisions on which action to take utilizing all available information gathered and stored so far to maximize cooperation efficiency. While designing such a module from scratch consumes large human expert efforts and is nearly impossible to generalize, we utilize powerful LLMs directly as the Planning Module by first retrieving the related information from the Memory Module and converting them into text descriptions as in the Communication Module, then compile an Action List of all available high-level plans proposed according to the current state and the procedural knowledge stored for the LLMs to make the choice, which formalization makes it easier for the LLMs to concentrate on the reasoning and make an executable plan without any few-shot demonstrations easily, finally prompting the LLMs with current information and the proposed Action List to generate a high-level plan. We also use the zero-shot chain-of-thought prompting technique introduced by Kojima et al. (2022) to encourage the LLMs to carry out more reasoning before giving the final answer. More details can be found in Appendeix. A.4.
+
+# 4.6 EXECUTION MODULE
+
+As shown in (Deitke et al., 2022), solving challenging embodied tasks requires modular methods to tackle the complexity of tasks. We found that while LLMs were effective at making high-level plans, they were poor at making low-level controls, as also discussed in (Wu et al., 2023). Thus, to enable effective and generalized cooperation decision-making in different environments, we design an Execution Module to generate primitive actions to execute a given high-level plan robustly in a specific environment, allowing the Planning Module to be generalizable and focus more on solving the overall task with LLMs’ rich world knowledge and strong reasoning ability. Practically, this design can also reduce the LLM inference time and is time-saving and economical. CoELA retrieves the procedures in its Memory Module regarding the plan generated by the Planning Module and then carries out the procedure with primitive actions suitable for the environment.
+
+# 5 EXPERIMENTS 5.1 EXPERIMENTAL SETUP
+
+ThreeDWorld Multi-Agent Transport (TDW-MAT) is a multi-agent embodied task extended from the ThreeDWorld Transport Challenge (Gan et al., 2022) with more types of objects and containers, more realistic object placements, and communication between agents supported, built on top of the TDW platform (Gan et al., 2021), which is a general-purpose virtual world simulation platform. The agents are tasked to transport as many target objects as possible to the goal position with the help of containers as tools. The agents receive ego-centric $5 1 2 \times 5 1 2$ RGB-D images as observation and have an action space of low-level navigation control, interaction, and communication. We selected 6 scenes from the TDW-House dataset and sampled 2 out of the two types of tasks food and stuff in each of the scenes, making a test set of 24 episodes, and instantiate the horizon $h$ with 3000 frames.
+
+Communicative Watch-And-Help (C-WAH) is extended from the Watch-And-Help Challenge (Puig et al., 2021) built on a realistic multi-agent simulation platform, VirtualHome-Social (Puig et al., 2018; 2021), where we focus more on cooperation ability and support communication between agents. We conduct experiments under both symbolic and visual observation settings. The task is defined as five types of common household activities and represented as various predicates with counts to be satisfied. We sampled 2 tasks from each of the five types of activities to construct a test set of 10 episodes and instantiate the horizon $h$ with 250 steps. More details can be found at Appendix. B.
+
+Metrics We use the Transport Rate $( T R )$ , the fraction of the sub-goals satisfied on TDW-MAT, and the Average Steps $L$ taken to finish the task on C-WAH as main efficiency metrics respectively and calculate Efficiency Improvement $( E I )$ of cooperating with other agents as $\Delta M / M _ { 0 } ^ { \dagger }$ , where $\Delta M$ denotes the main efficiency metric difference, and $M _ { 0 }$ denotes the larger one of the main efficiency metric for numerical stability.
+
+# 5.2 BASELINES
+
+MCTS-based Hierarchical Planner(MHP) is adopted from the strongest baseline in the original Watch-And-Help Challenge, which is a Hierarchical Planner with a high-level planner based on MCTS and a low-level planner based on regression planning (Korf, 1987).
+
+Rule-based Hierarchical Planner(RHP) is adopted from the strong performing baseline in the original ThreeDWorld Transport Challenge, which is a Hierarchical Planner with a high-level planner based on heuristics rules and a low-level A-start-based planner to navigate with semantic map, using Frontier Exploration strategy which randomly samples a way-point from an unexplored area as a sub-goal for exploration.
+
+Multi-Agent Transformer(MAT) is a MARL baseline that applies a centralized decision transformer to generate actions from shared observations (Wen et al., 2022). To apply MAT in our setting, we make the compromise to feed the oracle semantic map and the agent states as observation and stack up to 50 frames as an RL step since TDW-MAT is too hard for it with long-horizon and sparse reward signals. We train MAT on the training set with more details in Appendix. C.1.
+
+Implementation Details. We train a Mask-RCNN on the training set for the Perception Module and instantiate CoELA with the most powerful LLM GPT-4 from the OpenAI API1 with the default parameter of temperature 0.7, top-p 1, and max tokens 256 unless other stated. We also conduct experiments with Open LLM LLAMA-2-13b-chat (Touvron et al., 2023) and fine-tune a CoLLAMA with LoRA (Hu et al., 2021) on a small set of human-filtered high-quality trajectory data collected with our agents. More details are deferred to the Appendix. C.3.

+
+# 5.3.1 COLLABORATING WITH AI AGENTS
+
+CoELA cooperates better with baseline agent As shown in Table 1, compared with RHP doing the task alone, cooperating with CoELA leads to a higher TR and EI than cooperating with another RHP $( 0 . 6 9 ( 3 6 \% )$ v.s. $0 . 6 1 ( 2 9 \% ) )$ , even without any knowledge of the inner working mechanism of others, showing CoELA can reason about the other agent’s state well without hand-designed heuristics. From Table 2, we can observe the same performance boost of cooperating with CoELA on C-WAH of $45 \%$ compared to $33 \%$ of cooperating with the same MHP.

While replacing GPT-4 with open Model LLAMA-2 leads to a significant performance drop, our fine-tuned CoLLAMA can gain a competitive performance of $0 . 7 0 \ \mathrm { T R }$ and even surpass GPT-4 on the subtask of Stuff where GPT-4 performs not so well, showing the promising future of fine-tuning open LLMs with our proposed framework on embodied environments for even better cooperative embodied agents.
+
+CoELA exhibit efficient communication and effective cooperation behavior To better understand the essential factors for effective cooperation, we conduct a qualitative analysis of the agents’ behaviors exhibited in our experiments and identified several cooperative behaviors: CoELA share progress and information with others, know when to request help and can respond to others’ requests, can adapt plans considering others and knows when not to communicate, as shown in Figure 3. We discuss some here and the remaining in the Appendix. C.4.
+
+# 5.3.2 COLLABORATING WITH HUMANS
+
+It’s our ultimate goal to build agents that can cooperate with humans, a user study is important. We conducted human experiments on the C-WAH where the agent Alice is controlled by real humans.
+
+We recruited 8 human subjects to perform the experiments under four scenarios: cooperating with the $ { \mathbf { M H P } } ^ { 2 }$ , CoELA, CoELA w/o communication, and doing the task alone. Subjects have access to the same observation and action space as the agents, they can click on visible objects and select actions to interact with them, including navigation to each room and communication through a chat box. We gave each subject a tutorial and they had the chance to get familiar with the interface in a few pilot trials. We evaluate the same 10 tasks as in previous experiments and each task was performed by at least 2 subjects, making 80 trials in total. We made sure each subject do 10 trials with at least two trials under each scenario. After each trial including a baseline to cooperate with, we asked subjects to rate the agent they just cooperated with on a 7-point Likert Scale based on three criteria adapted from Puig et al. (2021): (i) How effective do you think of your communication with the other agent Bob? Did it understand your message and/or share useful information with you? (ii) How helpful do you find the other agent Bob? Did it help you achieve the goal faster? (iii) How much do you trust the other agent Bob? Would you feel safe doing the task with it, or you rather do the task alone?

+Figure 4: Human experiments results (a) The Average steps when collaborating with Humans and agents. (b) Subjective Rating Humans give when cooperating with different agents. Humans trust CoELA communicating in natural language more and cooperate more efficiently with them. Ablation results (c) The light-colored portions represent the number of steps used for communication. The Memory Module and a strong LLM for the Planning Module are important, while the Communication Module matters more when cooperating with humans.
+
+As we can see in Figure 4a, when cooperating with humans, CoELA still performs better than MHP, and when communication is unable, CoELA w/o communication encounters a performance drop. As reported in Figure 4b, we also observe that humans would trust the agents more if they can communicate with humans (trust score of 6.3 v.s. 4.7 for CoELA v.s CoELA w/o communication, $\mathrm { p } { = } 0 . 0 0 0 3$ over the t-test), and therefore achieves better cooperation. Compared with MHP using template language to communicate, humans prefer to collaborate with CoELA who communicates in natural language and can understand and respond to Human dialogues. We show an effective communication example in Figure 10, where the human first shares his progress with CoELA and suggests a labor division, CoELA understands and responds with its future plan as well, resulting in a perfect division of the exploration trajectory. These results imply promising futures for leveraging LLMs to build cooperative embodied agents that can successfully work with humans.
+
+# 5.4 ANALYSIS
+
+Do we need a strong LLM for the Planning and Communication Module? As shown in Figure 4c, when we replace GPT-4 with GPT-3.5 to drive CoELA, the agents would need more steps to finish the task. GPT-3.5 makes more reasoning errors about the state and therefore generates more implausible plans, which leads CoELA to spend more time finishing the task. GPT-3.5 also tends to generate unuseful messages more often than GPT-4. The performance gap can be attributed to more advanced reasoning and Theory of Mind abilities of GPT-4, which is also observed by Bubeck et al. (2023).
+
+Is the communication effective? Though communication still fails in some cases, as shown in Figure 3, our agent exhibits effective communication behaviors, such as sharing information, requesting help, responding to requests, and knowing when not to communicate. More importantly, natural language communication provides us with a lens to understand the decision-making of the agents and could lead to better cooperation between humans and AI (as shown in section 5.3.2). We did not observe a significant performance drop when disabling communication among AI agents (as shown in Figure 4c), because carrying out efficient communication in our setting is extremely challenging as communication costs time, requiring agents to model others accurately and understand the ambiguity of the natural language itself, which current LLMs still can not master robustly.
+
+Is the Memory Module and Execution Module effective? As shown in Figure $\mathrm { ~ \mathfrak ~ { ~ c ~ } ~ }$ , the steps needed to finish the task for the agent with no Memory Module nearly double, showing the importance of the Memory Module to store and update the knowledge and experience of the scene and the others. We also tried to remove the Execution Module and let the Planning Module make low-level control directly at every step. However, this slows down the inference process largely and all our trials perform poorly and struggle to finish any task.

+
+# 5.5 FAILURE CASES AND LIMITATIONS OF LLM
+
+Though CoELA built with sota LLMs is effective and has achieved impressive results, we find that the agent still falls short in several essential capabilities. We provide an in-depth analysis of its limitations and share some insights on designing better cooperative embodied agents for future work.
+
+Limited usage of 3D spatial information. CoELA did not incorporate the spatial information of objects and rooms into consideration due to the challenge of effectively introducing the spatial information to pure text language models. This may cause the agents to come up with a semantic sound exploration plan which is actually time-consuming. Work on multi-modal large models capable of both processing visual modalities effectively and generating natural language fluently (Huang et al., 2023; Driess et al., 2023; Lu et al., 2022) would help overcome this limitation and build better grounded embodied agents.
+
+Lack of effective reasoning on low-level actions. To help LLMs better focus on solving the overall task, we abstract high-level plans for LLMs to directly reason on, reducing the potential decision space significantly, but also making it unaware of the execution of low-level actions, and impossible to reason over them, which may lead to plausible but ineffective decisions. For example in Figure 5a, Alice saw Bob holding a container and a target object in both hands and figured he may not know how to utilize the containers, so sent a message to instruct him to put the object into the container, though Bob was actually putting in the objects at the same time, which is impossible for Alice to reason over now. Developing agents that can directly make low-level controls is essential for building better cooperative agents.
+
+Unstable performance on complex reasoning. Although LLMs make correct reasoning most of the time, they still occasionally make mistakes, including misunderstanding the environment rules specified in the prompt, and incorrect reasoning over the number of unsatisfied goals (Figure 5b). These mistakes can cause failures in planning. This calls for developing LLMs with stronger instruction following and reasoning capability.
+
+# 6 CONCLUSION
+
+In this work, we propose a novel modular framework integrating the Large Language Models to build cooperative embodied agents CoELA, who can plan, communicate, and collaborate efficiently with other agents and humans in a challenging multi-agent setting with decentralized control, complex partial observation, costly communication, and multi-objective long-horizon tasks. Our experiments on two extended embodied multi-agent environments show the effectiveness of our proposed framework and exhibit several cooperative behaviors. We fine-tune a CoLLAMA from LLAMA-2 using data collected with our agents in embodied environments and showcase its promising performance to build better cooperative embodied agents. We also discover that CoELA communicating in natural language can cooperate better with humans and earn more trust from them. We believe that our work indicates promising future avenues to design even stronger embodied agents with LLMs for multi-agent cooperation. We further perform an in-depth analysis of the limitations of the current LLMs and highlight several potential solutions for building better embodied cooperative agents for the future.

+# A ADDITIONAL DETAILS ON THE FRAMEWORK
+
+# A.1 PERCEPTION MODULE
+
+To deal with raw sensory observations, a well-constructed Perception Module is needed for embodied agents to extract useful information for downstream higher-order reasoning.
+
+In TDW-MAT, the environment provides an observation of $5 1 2 \times 5 1 2$ first-person view RGB image and Depth image. The agent first utilizes a pre-trained Mask-RCNN (He et al., 2017) to obtain the instance segmentation mask, then combines it with the depth image and the agent’s position to project each pixel into the 3D world coordinate to obtain a 3D voxel semantic map, and finally accumulates along the height dimension to build a top-down 2D semantic map of size $L \times W \times 3$ , where the first channel represents semantic classes including target objects, containers, destinations, and agents, and the last two channels represent the occupied and explored area respectively. Each element in the map denotes a grid of size $0 . 1 2 5 m \times 0 . 1 2 5 m$ in the scene. The agent also extracts the relationship of the objects with the help of instance segmentation masks and updates its Semantic Memory with the new information extracted from the observation.
+
+To obtain a more suitable model for instance segmentation in a TDW simulation environment, we fine-tune the MASK-RCNN model pre-trained on the MS COCO dataset in training scenes. By random sampling in the training environments, we collected 53 $\stackrel { \prime } { \scriptscriptstyle \mathrm { : \ 5 1 2 \times 5 1 2 } }$ RGB images and obtained the ground truth instance segmentation mask from the environment as the training set. The fine-tuned model achieves $8 1 . 4 \%$ mAP $\textcircled { a } 5 0$ in the test set.

+Figure 6: A visualization of the semantic map stored in the Semantic Memory and updated with new observations at every time in the TDW-MAT environment. The destination is shown in red, target objects are in blue, containers are in green, the agent is denoted with cyan, and the other agent’s position in memory is denoted in yellow.
+
+# A.2 MEMORY MODULE
+
+We mimic human’s long-term memory and design Semantic memory, Episodic Memory, and Procedural Memory for CoELA to store the knowledge and experience it has of the world, other agents, and itself.
+
+Semantic Memory stores CoELA’s knowledge about the world including a semantic map as shown in Figure 6 built and updated with local map perceived from the Perception Module, the task progress which is initialized with all zeros and updated whenever the agent is in the range of the goal position, the state of self including positions, holding objects status, and the state of others in memory which is updated whenever the others is perceived in the observation. To be noticed, CoELA’s knowledge about the world may not be accurate since other agents may interact with the objects and change their states without its awareness. Dealing with imparities between the memory and the description of the world from others adds even more challenges.
+
+Episodic Memory stores CoELA’s experience about the past including the action history and dialogue history. Each time CoELA executes a new action including sending out a message or receiving a new message, the related information is added to the Episodic Memory. Empirically, we only keep the last $K$ actions and $D$ dialogues for storage efficiency.
+
+Procedural Memory contains knowledge including how to carry out specific high-level plans in a specific environment implemented in code and the neural models’ parameters including LLMs and Mask-RCNN. In our current implementation, the Procedural Memory is never updated except for fine-tuning the model parameters, while it’s interesting to design a learning mechanism for it as in (Wang et al., 2023a) as well.

+It’s important for cooperative embodied agents to be able to communicate effectively with others.   
+Effective communication needs to solve two problems: what to send and when to send.
+
+We deal with the what to send problem in this module by directly using the LLMs as a Message Generator with designed prompts, constructed from the components of Instruction Head, Goal Description, States Description, Action History, and Dialogue History. To better constrain LLMs’ generated messages, we also add a note at the end of the prompt and append two seed messages at the beginning of the Dialogue History to elicit deserved effective communication behavior. The detailed prompt design is shown below:
+
+Instruction Head This part of the prompts is fixed for an environment, mainly consisting of the task instructions and environmental constraints.
+
+Goal Description For each task, the goal description is converted from $G = \{ g _ { 1 } , g _ { 2 } , . . . , g _ { k } \}$ using a formal template.
+
+State Description For each step, the state description is converted from task progress, state of self, state of others, and semantic map retrieved from the Memory Module through a template.
+
+Action History The concatenation of the last $K$ actions (high-level plans) the agent took.
+
+Dialogue History The Concatenation of the last $D$ dialogues between agents including the messages the agent itself has sent.
+
+To constrain the message generation of the LLMs, we add a note at the end of the prompt:
+
+Note: The generated message should be accurate, helpful, and brief. Do not generate repetitive messages.
+
+And append two seed messages at the beginning of the Dialogue History to elicit deserved effective communication behavior:
+
+Alice: "Hi, I’ll let you know if I find any goal objects, finish any subgoals, and ask for your help when necessary.”
+
+Bob: "Thanks! I’ll let you know if I find any goal objects, finish any subgoals, and ask for your help when necessary.”
+
+# A.4 PLANNING MODULE
+
+CoELA needs a strong Planning Module to make decisions on which action to take utilizing all available information gathered and stored so far to maximize cooperation efficiency.
+
+While designing such a module from scratch consumes large human expert efforts and is nearly impossible to generalize, we utilize powerful LLMs directly as the Planning Module by first retrieving the related information from the Memory Module and converting them into text descriptions as in the Communication Module, then compile an Action List of all available high-level plans proposed according to the current state and the procedural knowledge stored for the LLMs to make the choice, which formalization makes it easier for the LLMs to concentrate on the reasoning and make an executable plan without any few-shot demonstrations easily, finally prompting the LLMs with current information and the proposed Action List to generate a high-level plan. We also use the zero-shot chain-of-thought prompting technique introduced by Kojima et al. (2022) to encourage the LLMs to carry out more reasoning before giving the final answer.
+
+Action List We compile all available actions regarding the current state into an Action List for the LLMs to select from. The multi-choice formalization makes it easier for the LLM to make an executable plan without any few-shot demonstrations. All available high-level plans on the TDW-MAT include
+
+• go to room \*   
+• explore current room   
+• go grasp target object/container \*   
+• put holding objects into the holding container   
+• transport holding objects to the bed   
+• send a message: "\*"
+
+Answer Extraction As shown in (Wei et al., 2022), chain-of-thought prompting can unleash the strong reasoning ability of the LLMs, we use the zero-shot chain-of-thought prompting technique introduced by (Kojima et al., 2022) to encourage the LLM to carry out more reasoning before giving the final answer.
+
+# A.5 EXECUTION MODULE
+
+To enable effective and generalized cooperation decision-making in different environments, we design an Execution Module to generate primitive actions to execute a given high-level plan robustly in a specific environment, allowing the Planning Module to be generalizable and focus more on solving the overall task with LLMs’ rich world knowledge and strong reasoning ability. Practically, this design can also reduce the LLM inference time and is time-saving and economical. When facing a new environment with a different action space, only the procedural knowledge needs to be rewritten for CoELA to work. For rearrangement tasks, we mainly use an A-star-based planner to find the shortest path for navigation and robustly interact with the objects according to rules.
+
+# A.6 A WORKING EXAMPLE ON TDW-MAT
+
+To better understand our method, we present A working example of CoELA on one step in the TDW-MAT in Figure 7. CoELA receives an observation of $5 1 2 \times 5 1 2$ first-person view RGB image and Depth image from the environment, first uses the Perception Module implemented with MaskRCNN to predict an instance segmentation mask, then builds 3D point clouds and extracts the states (positions, names, IDs, objects holding if agents) of the key objects including target objects, containers, and the agents, and builds a local occupancy map. The Memory Module uses the extracted states of the key objects and the local occupancy map to construct and update the semantic map, which is stored in Semantic Memory. The Memory Module also stores the task progress, the states of the agents in the Semantic memory, and the agent’s action and dialogue history in the Episodic Memory, which are also updated when a message is received. The Communication Module converts the semantic map, task progress, and agents’ states into textual State Description and concatenates it with the Instruction Head, Goal Description, Action History, and Dialogue History as the prompt to condition the LLM on current states and generate the message to be sent beforehand. The Planning Module similarly takes these inputs and converts them into a prompt with the addition of an Action List compiled with all available high-level plans including sending the message just generated, then taking advantage of the chain-of-thought prompting to decide on the high-level plan "explore current room <Livingroom> (4000)". The Execution Module then uses an A-Star-based planner to find the shortest path from the current location to the target location with the help of the semantic map and gives the low-level primitive action of "Move forward $0 . 5 \mathrm { m } "$ , which is carried out in the environment and the new observation will be sent to the agents again.

+Figure 7: A working example on the TDW-MAT. The environment provides an observation of $5 1 2 ~ \ast$ 512 first-person view RGB image and Depth image. The Perception Module takes these in, builds 3D point clouds, then extracts the states (positions, names, IDs, objects holding if agents) of the key objects including target objects, containers, and the agents, and builds a local occupancy map. The Memory Module uses the extracted states of the key objects and the local occupancy map to construct and update the semantic map, which is stored in Semantic Memory. The Memory Module also stores the task progress, the states of the agents in the Semantic memory, and the agent’s action and dialogue history in the Episodic Memory, which are also updated when a message is received.

+Figure 8: TDW-MAT scenes, target objects, and containers.
+
+As an extension of the ThreeDWorld Transport Challenge(Gan et al., 2021), ThreeDWorld MultiAgent Transport (TDW-MAT) supports multi-agent cooperation with natural language communication and includes more types of objects with more realistic placements. In the new challenge, we use the latest replicant humanoid provided by the TDW platform as an embodiment.
+
+Tasks Two tasks are available in TDW-MAT: food-transporting task and stuff-transporting task. The two tasks have different types of target objects and containers. Figure 8 shows an overview of the two tasks: We create 4 floorplans and each of them has 3 layouts, where two floorplans are for the training set and another two are for the test set. The food-transporting task has 6 types of targets (apple, banana, orange, bread, loaf bread, and burger) and 3 containers (bowl, plate, and tea tray). In contrast, the stuff-transporting task has 6 different types of targets(calculator, mouse, pen, lighter, purse, and iPhone) and 3 containers (plastic basket, wood basket, and wicker basket). In each task, there are 10 target objects and 2 to 5 containers in total. Additionally, there are 4 types of rooms: living room, office, kitchen, and bedroom, and objects are placed in these rooms consistent with common sense. For example, food is more likely to be found in kitchens, while stuff is often in offices.
+
+The agents are tasked to transport as many target objects as possible to the goal position with the help of containers as tools. One container can carry most three objects, and without containers, the agent can transport only two objects at a time. Agents need to transport target objects as much as possible within 3000 frames.
+

+Figure 9: The RGB, depth, and oracle perception generated from the TDW-MAT environment.
+
+Observation Space The embodied agent receives the egocentric RGB image and depth image as the main observation, as well as some auxiliary observations. Figure 9 is an example of an image generated from the TDW-MAT environment, and the detailed observation space is listed here:
+
+• RGB image: the egocentric image comes from the camera facing forward, with screen size $5 1 2 \times 5 1 2$ and field of view 90;   
+• Depth image: the depth image has the same camera intrinsic parameters as the RGB image;   
+• Oracle Perception (optional): an image where each object id is mapped to a color and the camera intrinsic parameters are the same as the RGB image;   
+• Agent position and rotation: the agent’s position and rotation in the simulation world;   
+• Messages: the messages sent by all the agents;
+
+Action Space In TDW-MAT, there are 7 types of actions for agents to interact with the environment or communicate with each other. Each action takes several frames and the detailed action space is listed here:
+
+• Move forward: move forward $0 . 5 \mathrm { m }$ ;   
+• Turn left: turn left by 15 degrees;   
+• Turn right: turn right by 15 degrees;   
+• Grasp: grasp an object, only the agent is close to the object can he perform the action successfully. The object can be either a target or a container;   
+• Put In: put the target into the container, only the agent is holding a target in one hand and a container in another hand can he perform the action.   
+• Drop: drop the objects held in hand;   
+• Send message: Send a message to other agents. In each frame, no more than 500 characters can be sent.
+
+# B.2 COMMUNICATIVE WATCH-AND-HELP
+
+Communicative Watch-And-Help (C-WAH) is an extension of the Watch-And-Help challenge(Puig et al., 2021), which enables agents to send messages to each other. Sending messages, alongside other actions, takes one timestep and has an upper limit on message length.
+
+Tasks Five types of tasks are available in C-WAH, named Prepare afternoon tea, Wash dishes, Prepare a meal, Put groceries, and Set up a dinner table. These tasks include a range of housework, and each task contains a few subgoals, which are described by predicates. A predicate is in "ON/IN(x, y)" format, that is, "Put x ON/IN y". The detailed descriptions of tasks are listed in Table 3.
+
+The task goal is to satisfy all the given subgoals within 250 time steps, and the number of subgoals in each task ranges from 3 to 5.
+
+Table 3: Task description in C-WAH. There are 5 types of tasks and each of them contains a few predicates.   
+
+<table><tr><td>Task Name</td><td>Predicate Set</td></tr><tr><td>Prepare afternoon tea</td><td>ON(cupcake,coffeetable), ON(pudding,coffeetable), ON(apple,coffeetable), ON(juice,coffeetable), ON(wine,coffeetable)</td></tr><tr><td>Wash dishes</td><td>IN(plate,dishwasher),IN(fork,dishwasher)</td></tr><tr><td>Prepare a meal</td><td>ON(coffeepot,dinnertable),ON(cupcake,dinnertable), ON(pancake,dinnertable), ON(poundcake,dinnertable), ON(pudding,dinnertable), ON(apple,dinnertable), ON(juice,dinnertable), ON(wine,dinnertable)</td></tr><tr><td>Put groceries</td><td>IN(cupcake,fridge), IN(pancake,fridge), IN(poundcake,fridge), IN(pudding,fridge), IN(apple,fridge), IN(juice,fridge),</td></tr><tr><td>Set up a dinner table</td><td>IN(wine,fridge) ON(plate,dinnertable), ON(fork,dinnertable)</td></tr></table>
+
+Observation Space C-WAH has two observation modes, named Symbolic Observation and Visual Observation. For Symbolic Observation, we followed the setting of the original Watch-And-Help challenge, one agent can receive all the object information in the same room as the agent, and the information includes location, status, name, relationship, etc.
+
+For Visual Observation, agents can receive the egocentric RGB image and depth image, as well as some auxiliary observations. The detailed observation space is listed here:
+
+• RGB image: the egocentric image comes from the camera facing forward, with screen size $2 5 6 \times 5 1 2$ and field of view 60;   
+• Depth image: the depth image has the same camera intrinsic parameters as the RGB image;   
+• Oracle Perception: it is an image where each object id is mapped to a color and the camera intrinsic parameters are the same as the RGB image;   
+• Agent position: the agent’s position in the simulation world;   
+• Messages: the messages sent by all the agents.
+
+Action Space The action space is similar to that in the original Watch-And-Help Challenge, with a new action sending message added. The detailed action space is listed here:
+
+• Walk towards: move to an object in the same room with the agents or a room;   
+• Turn left: turn left by 30 degrees;   
+• Turn right: turn right by 30 degrees;   
+• Grasp: grasp an object, only the agent is close to the object can he perform the action successfully;   
+• Open: Open a closed container, only the agent is close to the container can he perform the action successfully;   
+• Close: Close an open container, only the agent is close to the container can he perform the action successfully;   
+• Put: Put the held objects into an open container or onto a surface, only the agent is close to the target position can he perform the action successfully;   
+• Send message: Send a message to other agents. no more than 500 characters can be sent at a time.
+
+# C ADDITIONAL DETAILS ON EXPERIMENTS
+
+C.1 TRAINING DETAILS ON THE MULTI-AGENT TRANSFORMERS
+
+Multi-Agent-Transformer(MAT) We adopt Multi-Agent-Transformer(MAT) (Wen et al., 2022), which regards MARL as a sequence modeling problem and applies a centralized decision transformer to generate actions.
+
+The input of MAT contains two parts, the first part is a top-down semantic map with size (12, 24) from the oracle perception. The map has 9 channels, implying whether the place is a free space/obstacle/wall/unexplored space/target object location/container location/goal location/my location/another agent’s location, and the second part is the agent information(whether holds a container, holding object counts, etc.). The output of MAT is one of the following actions: explore, navigate to the nearest target object, navigate to the nearest container, and navigate to the goal place. Each action will last for up to 50 frames or the action is finished.
+
+We train our RL agents for 2e5 frames with the hidden layer $\mathrm { d i m 6 4 }$ , learning rate $7 e - 4$ , ppo epoch 10 on training sets. After training, we test the RL agent on the test sets.
+
+# C.2 ADDITIONAL DETAILS ON OTHER BASELINES
+
+Rule-based Hierarchical Planner (RHP) We adopt the strong performing baseline from the original challenge, which is a Rule-based Hierarchical Planner with Frontier Exploration strategy, consisting of a rule-based high-level planner that selects one of the high-level plans from Exploration, Pick up an object, Pick up a container, and Place according to some human-defined rules and an A-star based planner to navigate with occupancy map and semantic map obtain and updated from the visual observation. The Frontier exploration strategy randomly samples a way-point from an unexplored area as a sub-goal for exploration.
+
+MCTS-based Hierarchical Planner (MHP) We adopt the strongest baseline from the original Watch-And-Help Challenge, which is a Hierarchical Planner with a high-level planner based on MCTS and a low-level planner based on regression planning (RP). MHP infers the other’s intention and adapts its subgoal accordingly based on the observation of the other agent.
+
+# C.3 ADDITIONAL DETAILS ON CoLLAMA
+
+We collected 2k trajectories from 10 episodes in the training set of TDW-MAT with GPT-4 driven CoELA and manually filtered 572 high-quality data with effective communication behavior and good reasoning trace towards collaborative decision-making. We use LoRA to fine-tune the LLAMA-2- 13b-chat with a batch size of 384, a maximal sequence length of 2048, and a max learning rate of $4 e ^ { - 4 }$ for 30 epochs (approximately 60 steps).
+
+# C.4 ADDITIONAL QUALITATIVE ANALYSIS OF THE AGENT BEHAVIORS
+
+CoELA exhibit efficient communication and effective cooperation behavior To better understand the essential factors for effective cooperation, we conduct a qualitative analysis of the agents’ behaviors exhibited in our experiments and identified several cooperative behaviors, as shown in Figure 3.
+
+CoELA shares progress and information with others. As shown in Figure 3abde, CoELA communicate with each other to share progress and intents, demonstrating the Communication Module can handle the challenge of what to send, harnessing the free dialogue generation ability from the LLMs.
+
+CoELA knows when to request help and can respond to others’ requests. In Figure 3d, Bob finds a target object in the living room but his container is already full, so he shares this information and requests Alice to come here to help. Alice responds by going there and grabbing the objects. Similarly in Figure 3b, Alice responds to Bob’s requests and questions. These examples show CoELA know when to request help and can understand others’ requests and responses.
+
+![](images/32179844c9530a3ccbed7946170099e038f35dc623b2e2c05ec06dbbe2bf3110.jpg)  
+Figure 10: A qualitative example in Human $. + C e$ oELA experiments, showcasing CoELA can communicate with Humans well and end up with a perfect division of the exploration trajectory.
+
+CoELA can adapt plans considering others. In Figure 3a, Bob suggests a labor division of himself going to the kitchen while Alice checks the other rooms, but Alice suggests a better plan given her circumstances that she’s already in the kitchen which Bob is not aware of before, and finally, Bob adapts his plan to cooperate with her.
+
+CoELA know when not to communicate. In Figure 3c, though Bob receives Alice’s suggestion of sharing any progress and has just found a plate, it’s more efficient for him to grab the objects by himself and get the job done since this is the last goal object. He successfully reasons about this and chooses not to communicate to achieve higher efficiency. We also observed this behavior from humans when conducting the same task.
+
+# C.5 ADDITIONAL DETAILS ON THE HUMAN EXPERIMENTS
+
+We show an effective communication example in Figure 10, where the human first shares his progress with CoELA and suggests a labor division, CoELA understands and responds with its future plan as well, resulting in a perfect division of the exploration trajectory. These results imply promising futures for leveraging LLMs to build cooperative embodied agents that can successfully work with humans.
+
+# D ADDITIONAL DISCUSSIONS
+
+CoELA is prone to cooperation Communication doesn’t ensure consensus, and arguing back and forth can consume significant time, resulting in reduced efficiency. Interestingly though understandable, we did not observe such a phenomenon during our experiments. CoELA is prone to cooperation and coordinate plans without arguing back and forth which may be credited to LLMs trained to follow instructions and trust their cooperators. This behavior is beneficial for cooperation, though it may lead to less efficiency when the cooperator is malicious.
+
+Language Agents for Embodied Planning With the recent advance of Large Language Models, there has been work emerging to leverage LLMs to build powerful Embodied Agents. Huang et al. (2022a) used GPT-3 to generate high-level plans directly in a non-interactive way and used another smaller Language Model to translate the plan to available actions on virtualhome. Liang et al. (2022); Song et al. (2022) used codes or few-shot prompting to directly generate plans, Huang et al. (2022b) built an inner monologue with environment feedback to improve planning, Ahn et al. (2022) combined robotic affordances and LLMs for grounded instruction following. More recently, Park et al. (2023) built an agent society using LLMs augmented with memories in a sandbox environment to simulate human behavior. In contrast to the above, our work addresses a more challenging multiagent cooperation problem, characterized by decentralized control, complex observations, costly communication, and long-horizon multi-objective tasks.

+
+Answer: Let’s think step by step.
+
+# LLM outputs
+
+First, we know that Bob is already holding an <apple> (387) and is in the <livingroom>. We also know that we need to find and put 1 wine, 1 pancake, 1 poundcake, 1 juice, and 1 apple onto the <kitchentable> (130). Since we are already in the <kitchen> and there are several unchecked containers, the best course of action is to continue searching the kitchen cabinets and appliances for the remaining items.
+
+So, the best available action for Alice is: D. [gocheck] <kitchencabinet> (137)

+J. go to <Livingroom> (6000)   
+Answer: Let’s think step by step.
+
+# LLM outputs
+
+First, we need to collect the remaining target objects. You should go to the <Livingroom> (6000) to grasp the <pen> (1440084) since it’s a target object. So, the best available action is: B. go grasp target object <pen> (1440084)
+
+# F TEMPLATE LANGUAGE COMMUNICATION FOR MCTS-BASED HP AGENT
+
+To enable the MCTS-based Hierarchical Planner to also leverage the new communication capability, we design three types of template language communication for it.
+
+Progress Sharing $P$ An important motivation for communication is to share progress with others to update each other about the total progress of the task. So we design the first template communication to share progress.
+
+When the agent carries out the action of put, which implies a new subgoal has been achieved by the agent, it will send a message such as:
+
+$\mathbf { \nabla } \cdot \mathbf { P } ^ { \prime }$ : ’I successfully put poundcake $< 3 8 3 >$ on kitchentable ${ < } I 3 O { > }$ , and they are in kitchen $< 5 6 >$ . ’
+
+When the agent receives such a message, it will process it and extract the sub-goal satisfied, and use it to update its inner tracking of the task progress, so avoiding taking an already satisfied sub-goal as a sub-goal again to better cooperate.
+
+Intent Sharing I Another important motivation for communication is to share intent with each other so that all the agents can plan coordinately together. So we design a template communication to share intent.
+
+When the agent changes its sub-goal (practically, the Monte Carlo Tree Search High-Level Planner gives a new plan), it will tell the other agents its current sub-goal by sending a message such as:
+
+’I’: ’Now I want to put cutleryfork $< 3 6 9 >$ in dishwasher ${ < } I O 4 { > }$ , and I have not found it yet. ’
+
+When the agent receives such a message, it will process it and extract the other agents’ new sub-goal and update its belief about the others’ intents, so it will not choose the same sub-goal with the others to avoid duplicate and improve efficiency.
+
+Belief Sharing $B$ Sharing the scenes the agent just sees to the other agents can help them update their belief of the location of the object as well, and more importantly, this can help agents to build common ground on the belief of the objects to better cooperate together. So we also design a template communication to share beliefs.
+
+When entering a new room, the agent will send all goal objects found or containers newly checked with no findings or target objects in it to others, such as:
+
+$\ ' B ' \cdot \ '$ found nothing is inside kitchencabinet $< 7 5 >$ . nothing is inside kitchencabinet $< 7 6 >$ . nothing is inside dishwasher ${ < } I O 4 { > }$ . nothing is inside cabinet $< 2 l \delta >$ . cutleryfork $< 3 6 9 >$ , cutleryfork ${ < } 3 7 0 { > }$ and plate ${ < } 3 7 3 \mathrm { > }$ are inside kitchen $< l I >$ .’
+
+When the agent receives such a message, it will process and extract the information maintained in the message to update its belief of the location distributions of the objects just as it has been seen by itself.
+
+Also to be noticed, the agents may combine these three types of template communication to send one combined message at one time instead of multiple messages over several steps to improve efficiency.

+# ABSTRACT
+
+Code Large Language Models (Code LLMs), such as StarCoder, have demonstrated remarkable performance in various code-related tasks. However, different from their counterparts in the general language modeling field, the technique of instruction fine-tuning remains relatively under-researched in this domain. In this paper, we present Code Evol-Instruct, a novel approach that adapts the Evol-Instruct method to the realm of code, enhancing Code LLMs to create novel models WizardCoder. Through comprehensive experiments on five prominent code generation benchmarks, namely HumanEval, HumanEval+, MBPP, DS-1000, and MultiPL-E, our models showcase outstanding performance. They consistently outperform all other open-source Code LLMs by a significant margin. Remarkably, WizardCoder 15B even surpasses the well-known closed-source LLMs, including Anthropic’s Claude and Google’s Bard, on the HumanEval and HumanEval+ benchmarks. Additionally, WizardCoder 34B not only achieves a HumanEval score comparable to GPT3.5 (ChatGPT) but also surpasses it on the HumanEval+ benchmark. Furthermore, our preliminary exploration highlights the pivotal role of instruction complexity in achieving exceptional coding performance.
+
+# 1 INTRODUCTION
+
+Recently, Large Language Models (LLMs) (Brown et al., 2020; OpenAI, 2023; Chowdhery et al., 2022; Anil et al., 2023; Hoffmann et al., 2022; Rae et al., 2021; Zeng et al., 2022; Zhang et al., 2022; Touvron et al., 2023a) have garnered immense attention and demonstrated impressive success. Notably, OpenAI’s GPT3.5 (ChatGPT) stands out as a prominent example. These models, through extensive pre-training on vast internet data and fine-tuning with detailed instruction data (Ouyang et al., 2022), have achieved state-of-the-art (SOTA) zero-shot performance across diverse NLP tasks. This trend also extends to the realm of code understanding and generation, where a multitude of Code LLMs have emerged (Chen et al., 2021a; Li et al., 2022; Fried et al., 2022; Nijkamp et al., 2023b; Zheng et al., 2023; Wang et al., 2021; 2023; Li et al., $2 0 2 3 \mathrm { a }$ ; Nijkamp et al., $2 0 2 3 \mathrm { a }$ ; Roziere \` et al., 2023). These models, pre-trained on substantial code data, excel in various code-related tasks, consistently delivering impressive performance.
+
+In contrast to most previous Code LLMs that primarily focus on the pre-training process, there has been limited exploration of fine-grained instruction tuning in the code domain. The introduction of instruction tuning was initially designed to enhance the generalization capabilities of LMs across different tasks via multitask training (Raffel et al., 2020; Wei et al., 2022; Chung et al., 2022; Aribandi et al., 2022; Sanh et al., 2022; Xu et al., 2022; Khashabi et al., 2020). OpenAI’s InstructGPT (Ouyang et al., 2022), for instance, involved soliciting human annotators to provide explicit instructions to ensure alignment with users’ intentions. Similarly, recent works such as Alpaca (Taori et al., 2023) employed the self-instruct (Wang et al., 2022) method, where GPT3.5 (ChatGPT) generated the instruction data. Vicuna (Chiang et al., 2023) utilized user-shared conversations collected from ShareGPT.com. WizardLM (Xu et al., 2023) introduces the Evol-Instruct method, which involves evolving existing general instruction data to generate more complex and diverse datasets. Drawing inspiration from these previous works in the general domain, our work, Code Evol-Instruct, is specifically tailored to the coding domain’s distinctive characteristics.

+Figure 1: An illustration of our novel Code Evol-Instruct and the superior pass $@ 1$ performance of our WizardCoder 34B, outperforming the open-source SOTA (CodeLlama-34B-Series as of the date before August 24, 2023) by a large margin in 9 different programming languages. The Python score is the mean between HumanEval and MBPP.
+
+In this study, we aim to enhance the capabilities of the SOTA open-source Code LLMs (i.e., StarCoder and CodeLlama), by introducing our novel Code Evol-Instruct. The motivation of this fine-grained instruction-tuning method in the code domain is to automatically increase the complexity of code instruction data, so as to make the best of the internal coding ability of the Code LLMs. Our Code Evol-Instruct incorporates several novel methods, including heuristics tailored to coding task features, adversarial sample heuristics, time/space complexity requirements, and evolving stop controls. The whole process includes two steps: initially, we apply our Code Evol-Instruct to evolve basic code instruction data, specifically Code Alpaca (Chaudhary, 2023). Subsequently, we fine-tune StarCoder and CodeLlama using our newly generated code instruction-following training set, resulting in our WizardCoder models.
+
+Figure 1 and the experimental results obtained from five code generation benchmarks, namely HumanEval (Chen et al., 2021b), HumanEval+ (Liu et al., 2023), MBPP (Austin et al., 2021), DS100 (Lai et al., 2022), and MultiPL-E (Cassano et al., 2022), demonstrate that our WizardCoder models outperform all other open-source Code LLMs (before August 24, 2023), achieving state-of-the-art (SOTA) performance. Remarkably, our WizardCoder 15B even surpasses well-known Anthropic’s Claude and Google’s Bard in terms of pass rates on HumanEval and HumanEval+. Furthermore, WizardCoder 34B not only achieves a HumanEval score comparable to GPT3.5 (ChatGPT) but also surpasses it on the HumanEval $^ +$ benchmark. Beyond this, our preliminary studies indicate that the complexity of instructions is the key to achieving exceptional coding performance.
+
+The contributions of this work can be summarized as follows:
+
+• We introduce Code Evol-Instruct, a novel instruction fine-tuning approach for code, which enhances the performance of the open-source Code LLMs by a large margin.   
+• We develop WizardCoder models, which surpass all other open-source Code LLMs by a substantial margin in coding tasks. Notably, the 15B version even outperforms the well-known closed-source LLMs, such as Claude, and Bard. The 34B version achieves a HumanEval score comparable to GPT3.5 (ChatGPT) and surpasses it on the HumanEval+ benchmark.   
+• We conduct a preliminary study highlighting the pivotal role of instruction complexity in achieving exceptional coding performance.
+
+# 2 RELATED WORK
+
+Large Language Models. Recently, LLMs have demonstrated remarkable achievements across a broad spectrum of tasks. Prominent tech companies have made significant strides in developing highly proficient LLMs. These include OpenAI’s GPT3&4 (Brown et al., 2020; OpenAI, 2023), Google’s PaLM (Chowdhery et al., 2022; Anil et al., 2023), and Bard1, DeepMind’s Chinchilla (Hoffmann et al., 2022), and Gopher (Rae et al., 2021), as well as Anthropic’s Claude2. However, it is important to note that these models are closed-source and can only be accessed through specific APIs or may not be accessible at all.
+
+The AI community has witnessed the release of several open-source LLMs, where the model weights are made publicly available. EleutherAI has contributed GPT-NeoX-20B (Black et al., 2022) and GPT-J-6B (Wang & Komatsuzaki, 2021). Google has released UL2-20B (Tay et al., 2022). Tsinghua University has introduced GLM-130B (Zeng et al., 2022). Meta has released OPT (Zhang et al., 2022) and LLaMA1&2 (Touvron et al., 2023a;b). It is worth noting that while these open-source models have made valuable contributions, they generally do not exhibit the same level of performance as their closed-source counterparts.
+
+Large Language Models for Code. Recent studies have introduced a significant number of LLMs for code-related tasks to address the challenges of code understanding and generation. OpenAI has unveiled Codex (Chen et al., 2021a) and Code-Davinci (Microsoft, 2023). Google has proposed PaLM-Coder (Chowdhery et al., 2022). They perform outstandingly on the popular code completion benchmarks, like HumanEval (Chen et al., 2021b) and MBPP (Austin et al., 2021). However, these models are closed-source.
+
+On the other hand, there are several open-source Code LLMs available. Salesforce has introduced CodeGen1&2 (Nijkamp et al., 2023b;a), CodeT5 (Wang et al., 2021), and CodeT5+ (Wang et al., 2023). Tsinghua University has contributed CodeGeeX (Zheng et al., 2023), and the BigCode Project has developed StarCoder (Li et al., 2023a). Meta has released the CodeLlama-Series (Roziere et al., \` 2023), which achieves open-source SOTA performance on several benchmarks. The closely related model, CodeLlama-Instruct, refines its performance through the self-instruct method. These models have demonstrated notable advancements in code-related tasks. However, when compared to the SOTA closed-source models, they still lag behind significantly. In contrast to the aforementioned models, our work demonstrates that further training Code LLMs with our Code Evol-Instruct can substantially enhance performance.
+
+Instruction Fine-Tuning. The primary objective of instruction fine-tuning in its early stages was to enhance the cross-task generalization capabilities of LMs. This was achieved by fine-tuning LMs with a substantial corpus of public NLP tasks. T5 (Raffel et al., 2020) was among the first models to explore this approach, training on a multitude of supervised text-to-text tasks. Subsequent works such as FLAN (Wei et al., 2022), ExT5 (Aribandi et al., 2022), T0 (Sanh et al., 2022), and UnifiedQA (Khashabi et al., 2020) further expanded the range of tasks to bolster the overall generalization ability of LMs. Notably, ZeroPrompt (Xu et al., 2022) and FLAN-T5 (Chung et al., 2022) pushed the envelope by incorporating thousands of tasks in their training pipelines. Across these studies, a consistent finding emerges: fine-tuning LMs with diverse NLP task instructions yields significant performance improvements when applied to new tasks.
+
+While fine-tuning LMs with diverse NLP tasks has shown promising results, it often falls short in aligning with the intentions of real-world users. OpenAI has pursued a different approach by soliciting human annotators to provide a large corpus of human instructions, encompassing diverse forms and a wide range of task types. Building upon this dataset, OpenAI trained its GPT3 (Brown et al., 2020) model to create InstructGPT (Ouyang et al., 2022), which better aligns with users’ inputs. This line of development has even led to the impressive work known as GPT3.5 (ChatGPT). However, it is important to note that the dataset and model weights associated with these advancements are not publicly available. Alpaca (Taori et al., 2023) takes a different route by adopting the selfinstruct method (Wang et al., 2022), leveraging GPT3.5 (ChatGPT) to generate data for training. Vicuna (Chiang et al., 2023) utilizes user-shared conversations collected from ShareGPT.com to train its models. WizardLM (Xu et al., 2023) introduces the Evol-Instruct method, which involves evolving existing general instruction data to generate more complex and diverse datasets. Drawing inspiration from this idea, our work, Code Evol-Instruct, aligning with the distinctive characteristics of coding domains, is the first instruction fine-tuning method explicitly designed to enhance Code LLMs.
+
+# 3 WIZARDCODER: SOTA OPEN-SOURCE CODE LLM
+
+In this section, we elaborate on the methodological details of WizardCoder. As illustrated in Figure 1, we first adopt our Code Evol-Instruct to iteratively evolve the Code Alpaca dataset. Subsequently, we fine-tune the pre-trained Code LLMs with the evolved data.
+
+# 3.1 CODE EVOL-INSTRUCT
+
+Inspired by the Evol-Instruct method proposed by WizardLM Xu et al. (2023), this work attempts to automatically enhance the complexity of code instructions, thereby improving the fine-tuning effectiveness of Code LLMs. Diverging from the general domain, our methods are meticulously designed to align with the specific characteristics of coding domains. The evolutionary process introduces the following features:
+
+1. Heuristics aligned with coding task features on platforms like LeetCode, strategically increasing the complexity of coding tasks to enhance the model’s capabilities.   
+2. Introduction of erroneous code as an adversarial sample, inspired by prior research on attacking pre-trained code models Yang et al. (2022); Jha & Reddy (2022), adds a novel and effective method to escalate task complexity.   
+3. Introduction of a heuristic emphasizing time and space complexity leverages insights from previous studies Madaan et al. (2023), providing a valuable avenue for improving task complexity.
+
+So, the code evolutionary prompt template is as follows:
+
+# Prompt for Code Evol-Instruct
+
+Please increase the difficulty of the given programming test question a bit.
+
+You can increase the difficulty using, but not limited to, the following methods:   
+{method}   
+{question}
+
+Here, $\{ { \mathrm { q u e s t i o n } } \}$ represents the current code instruction awaiting evolution, and $\{ { \mathrm { m e t h o d } } \}$ is the type of evolution. The five types we used are listed as follows:
+
+# Code Evolution Heuristic Methods
+
+Add new constraints and requirements to the original problem, adding approximately 10 additional words.
+
+Replace a commonly used requirement in the programming task with a less common and more specific one.
+
+If the original problem can be solved with only a few logical steps, please add more reasoning steps.
+
+Provide a piece of erroneous code as a reference to increase misdirection.
+
+Propose higher time or space complexity requirements, but please refrain from doing so frequently.
+
+# 3.2 TRAINING WizardCoder
+
+We employ the following procedure to train WizardCoder. Initially, we utilize StarCoder 15B (Li et al., 2023a) and CodeLlama-34B-Python (Roziere et al., 2023) as the foundations and proceed to \` fine-tune them using the code instruction-following training set, which was evolved through Code Evol-Instruct. The prompt format for fine-tuning is outlined as follows:
+
+# Prompt for Fine-Tuning Format
+
+Below is an instruction that describes a task, paired with an input that provides further context. Write a response that appropriately completes the request.
+
+### Instruction: {instruction} ### Response:
+
+To construct the training dataset, we initialized it with the instruction-following dataset called Code Alpaca3. We iteratively employ the Code Evol-Instruct technique on this dataset consisting of around $2 0 \mathrm { k }$ samples to produce evolved data. After each round of data evolution, we merge the evolved data from all previous rounds with the original dataset to finetune Code LLMs. An external dev set serves as the controlled Evol Stop. If the performance drops, we halt the evolution. In Appendix C, we outline the approach employed to prevent data leakage. Additionally, Appendix D showcases some evolved examples for reference.
+
+# 4 EXPERIMENT
+
+This section begins by providing a comprehensive overview of the baseline models in our experiments. Subsequently, we present the performance of our models on five code generation benchmarks: HumanEval (Chen et al., 2021b), HumanEval+ (Liu et al., 2023), MBPP (Austin et al., 2021), DS-1000 (Lai et al., 2022) and MultiPL-E (Cassano et al., 2022).
+
+# 4.1 BASELINES
+
+Closed-Source Models. Multiple technology companies have successfully developed highly proficient LLMs while choosing not to publicly release them. These models are referred to as closed-source models. For our research, we incorporate a substantial number of these models as our baselines. Specifically, our baselines encompass the following: (i) OpenAI’s GPT3.5(ChatGPT)&GPT4 (OpenAI, 2023), Code-Davinci-002 (Microsoft, 2023), Code-Cushman-001 (Microsoft, 2023), and

+
+Codex (Chen et al., 2021a); (ii) Google’s Bard, PaLM 2 (Anil et al., 2023), PaLM (Chowdhery et al., 2022), and LaMDA (Thoppilan et al., 2022); (iii) Google DeepMind’s AlphaCode (Li et al., 2022);(iv) Anthropic’s Claude; (v) Huawei’s PanguCoder2 (Shen et al., 2023); and (vi) Meta’s Unnatural-CodeLlama-34B (Roziere et al., 2023). \`
+
+Open-Source Models. Several open-source LLMs (OSS) have been made available to the AI community, although their performance generally lags behind the closed-source models a lot. As part of our research, we incorporate a significant number of these open-source models as our baselines. Our baselines encompass the following models: InCoderFried et al. (2022), StarCoder and StarCoderPlus (Li et al., 2023a), LLaMa1&2 (Touvron et al., 2023a;b), CodeGen (Nijkamp et al., 2023b), CodeGeeX (Zheng et al., 2023), CodeT5 $^ +$ (Wang et al., 2023), and CodeLlama (Roziere et al., 2023). \` In addition, we also include several models with instructions fine-tuning, including CodeLlamaInstruct (Roziere et al., 2023), OctoCoder (Muennighoff et al., 2023), InstructCodeT\` $^ { 5 + }$ (Wang et al., 2023), Instruct-Codegen-16B,4 Guanaco-65B (Dettmers et al., 2023), Falcon-40B-Instruct (Penedo et al., 2023) and Vicuna-13B (Chiang et al., 2023). More details can be found in the Appendix B.
+
+# 4.2 IMPLEMENTATION DETAILS
+
+The StarCoder and CodeLlama-34B-Python serve as our basic foundation models. OpenAI’s gpt3.5- turbo is used to evolve the dataset and generate responses. The evolved dataset consists of approximately 78k samples. To fine-tune the basic models, we employ specific configurations, including a batch size of 512, a sequence length of 2048, 200 fine-tuning steps, 30 warmup steps, a learning rate of 2e-5, a Cosine learning rate scheduler, and fp16 mixed precision.
+
+4.3 EVALUATION ON HUMANEVAL, HUMANEVAL $^ +$ , AND MBPP
+
+HumanEval (Chen et al., 2021b), HumanEva $^ +$ (Liu et al., 2023), and MBPP (Austin et al., 2021) are key benchmarks in the Code LLM field, featuring diverse Python programming problems validated using test cases. HumanEval comprises 164 problems with an average of 9.6 test cases per problem. HumanEval $^ +$ expands the test cases significantly to an average of 774.8 per problem. In contrast, MBPP provides 500 test programming problems with three automated test cases each.5
+
+Comparing with the Closed-Source Models. Following the same setting of the EvalPlus leaderboard (Liu et al., 2023). In Figure 2, we compare our WizardCoder models with the closed-source models, such as GPT4, Claude, and Bard on this leaderboard. Notably, all models generate code solutions for each problem utilizing a single attempt, and the resulting pass rate percentage is reported. To maintain consistency, we employ the same experimental setup by generating answers using greedy decoding and evaluate our WizardCoder models using the provided evaluation codes.
+
+Table 1: Results of pass $@ 1 ( \% )$ on HumanEval and MBPP. We follow the previous works (Chen et al., 2021b) to generate $\scriptstyle \mathrm { n = 2 0 0 }$ samples to estimate the pass $@ 1$ score of our WizardCoder models with the same set of hyper-parameters: temperate $= 0 . 2$ , and top $\mathtt { - p = } 0 . 9 5$ . \*: our reproduced results.

+
+As depicted in Figure 2, our WizardCoder 34B attains the second position in this benchmark, surpassing GPT3.5 (ChatGPT, 64.6 vs. 63.4) on HumanEval+. Our 15B version outperforms ClaudePlus (59.8 vs. 53.0) and Bard (59.8 vs. 44.5). Furthermore, our WizardCoder models demonstrate a remarkable superiority over other open-source LLMs that undergo instruction fine-tuning.
+
+Comparing with the Open-Source Models. In Table 1, we conduct a comprehensive comparison of our WizardCoder with other open-source models on the HumanEval and MBPP benchmarks. In contrast to the results presented in Figure 2, we adhere to the approach outlined in previous studies Chen et al. (2021b) by generating n samples for each problem to estimate the pass $@ 1$ score. The findings presented in Table 1 clearly demonstrate that our WizardCoder exhibits a substantial performance advantage over all the open-source models.
+
+# 4.4 EVALUATION ON MULTI-LANGUAGE CODING
+
+We included comprehensive assessment results across 8 distinct programming languages on the MultiPL-E benchmarks. These languages encompass Java, JavaScript, $\mathrm { C } { + } { + }$ , PHP, R, Julia, Swift, and Rust. The empirical results, as presented in Table 2, distinctly demonstrate the superior performance of our WizardCoder models across all evaluated programming languages, surpassing the SOTA open-source Code LLMs. This underscores the efficacy of our Code Evol-Instruct method.
+
+# 4.5 EVALUATION ON DS-1000
+
+The DS-1000 benchmark Lai et al. (2022) comprises 1k distinct data science workflows spanning 7 libraries. It assesses the performance of code generations against test cases and supports two evaluation modes: completion and insertion. In our experiments, we only report insertion scores for

+Evolution Models and Rounds. In Table 4, GPT4 replaces GPT-3.5 for evolved rounds, boosting HumanEval Pass $@ 1$ scores to 73.8 (34B) and 62.2 (15B). Using OSS CodeLlama-Instruct-34B also proves effective, yielding scores of 70.1 (34B) and 55.5 (15B). Despite GPT-4’s superior coding performance (88.4 vs. 73.2), the gain in evolved rounds is not proportional (73.8 vs. 73.2). Conversely, CodeLlama’s weaker performance narrows when using Code Evol-Instruct (73.2 vs. 70.1), highlighting its crucial role. More experiments details are listed in Appendix E. Additionally, Figure 3 presents results for different data evolution rounds. All models are fine-tuned with 200 steps. Due to the limited size of the dev set of MBPP, we merged the training set and dev set, forming the MBPP-400 dev set. The experiments reveal that the highest pass $@ 1$ scores on both the MBPP-400 dev set and the HumanEval are achieved subsequent to three rounds of evolution.

+
+Complexity and Quantity. While the enhanced performance attributed to our Code Evol-Instruct method has been evident in prior experiments, it remains an open question whether this performance gain is a result of an increase in the number of samples or tokens. During the evolution, each round includes more samples, and the introduction of more complex instructions inevitably leads to an increase in tokens within the training data. To address this question, we fine-tune the models using only the specific round data separately from scratch with a similar number of samples (upper part) or tokens (lower part) in Table 5.
+
+When each round contains the same number of samples or tokens, the models trained with the seed data still lag behind the evolved rounds. Furthermore, combining data from different rounds leads to the best performance. These results suggest that the primary source of the gain is indeed attributable to our Code Evol-Instruct method, rather than merely an increase in samples or tokens.
+
+Table 5: Analysis of whether the performance gain comes from more tokens.

+
+Complexity and Similarity. Apart from the quantity analysis, we also investigate whether evolution leads to the inclusion of data more similar to the test set. To address this, we perform an analysis of the HumanEval test set. We employ test samples as queries to retrieve the top-1 sample from each evolved round’s training data, utilizing the SOTA embeddings model, gte-large (Li et al., 2023b). Additionally, we employ GPT4, to provide average similarity scores between the test set and the retrieved top-1 samples. The details are shown in Appendix C.
+
+Figure 4 illustrates that the evolution process does not yield higher similarity scores. Furthermore, similarity scores across all rounds remain relatively low. These findings indicate that the primary source of performance gain is the introduction of more complex data.
+
+# 6 CONCLUSION AND FUTURE WORK
+
+This paper introduces WizardCoder models, the Code EvolInstruct fine-tuned Code LLMs. The experimental results demonstrate that WizardCoder models achieve SOTA performance surpassing all existing open-source Code LLMs on five widely recognized code generation benchmarks: HumanEval, HumanEval $^ +$ , MBPP, DS-1000 and MultiPLE. Notably, WizardCoder $1 5 B$ model surpasses some of the well-known closed LLMs, such as Claude and Bard. Additionally, WizardCoder 34B achieves a HumanEval score comparable to GPT3.5 (ChatGPT) and surpasses it on the HumanEva $^ +$ benchmark. Furthermore, our analysis underscores the pivotal role of instruction complexity in enhancing performance. For future work, as depicted in Figure 2, our model still falls significantly behind the SOTA LLM, GPT4. Therefore, future work will further augment the performance of our model.

+# A PROMPT FORMATS
+
+In this section, we include the prompt for evaluation on different tasks.
+
+# Zero-Shot Prompt for Evaluation on HumanEval and HumanEval+
+
+Below is an instruction that describes a task, paired with an input that provides further context. Write a response that appropriately completes the request.
+
+### Instruction:   
+Create a Python script for this problem:   
+{Question}
+
+### Response:
+
+# Three-Shot Prompt for Evaluation on MBPP
+
+Below is an instruction that describes a task, paired with an input that provides further context. Write a response that appropriately completes the request.

+### Instruction:   
+Create a Python script for this problem:

+{Test Example 1}   
+{Test Example 2}   
+{Test Example 3}
+
+### Response:
+
+# Zero-Shot Prompt for Evaluation on DS-1000 (Completion)
+
+Below is an instruction that describes a task, paired with an input that provides further context. Write a response that appropriately completes the request.
+
+### Instruction:   
+{Question}   
+Complete the Python code in ”...”.
+
+### Response:
+
+In the case of DS-1000 (Insertion), adherence to the benchmark’s specifications necessitates the utilization of StarCoder’s specialized insertion symbol. Consequently, we have found it imperative to align with the same prompt format employed by StarCoder for this particular benchmark.
+
+For the MultiPL-E benchmark, we recognized the need to align with the evaluation codes provided by bigcode-evaluation-harness.7 Consequently, we opted to adopt the same prompt format utilized by StarCoder.
+
+# B BASELINES DETAILS
+
+We include a large amount of models as our baselines. For GPT3.5 (ChatGPT)&GPT4. their results are obtained from GPT4’s report and EvalPlus. The results of Code-Davinci-002, Code-Cushman-001, Codex, PaLM, PaLM 2, LaMDA, AlpahaCode, Incoder, StarCoder, LLaMa, CodeGen, CodeGeeX, CodeT $^ { 5 + }$ , and InstructCode $\Gamma 5 +$ are from StarCoder or CodeT5 $+$ ’s paper. The results of Bard are evaluated with Google’s API. The results of Claude are evaluated with Anthropic’s API. The results of Instruct-Codegen-16B, Guanaco-65B, Falcon-40B-Instruct, and Vicuna-13B are evaluated with the open-sourced checkpoints. The results of CodeLlama-Series are from CodeLlama’s paper. The results of OctoCoder are from its paper. The results of PanguCoder2 are also from its paper.
+
+The MBPP score of StarCoder differs from that in its original paper. Through a personal contact, we were informed that StarCoder was evaluated using a cleaned and smaller version of MBPP, comprising only 397 problems, significantly fewer than the original MBPP benchmarks (500). Consequently, we conducted a re-evaluation of StarCoder using the original MBPP.
+
+# C SIMILARITY CHECKING AND DATA FILTERING
+
+The prompt formats to compute the similarity score are as follow:
+
+# System Prompt for Similarity Checking
+
+Your task is to evaluate the similarity of the two given coding tasks. Please review the two coding tasks carefully, paying close attention to the overlap in function names, code structures, topics, and contents. Once you have carefully reviewed both coding tasks, provide a similarity score between these two coding tasks. The score should range from 1 to 10 (1: completely different coding tasks; 10: identical coding tasks). You only need to provide your score. The response format is:   
+Score:
+
+# User Input for Similarity Checking
+
+# Task1 {task1} # Task2 {task2}
+
+To thoroughly prevent data leakage from the test datasets to the training dataset, we implemented an additional data filtering step. Utilizing the SOTA embeddings model, gte-large, we treated all test samples as queries to extract the top 5 samples from the training data. Following this, GPT-4 was employed to evaluate the similarity between the retrieved samples and the test sample. The task for GPT-4 is simplified to a binary decision—either a “yes” or “no” indicating a match. In case of a positive match, the sample is excluded from the training data.
+
+# D EVOL EXAMPLES
+
+In this section, we present some evolved examples to elucidate the influence exerted by our Code Evol-Instruct.
+
+Example 1:
+
+• Round 0: Write a MongoDB query to select all documents in a collection where the field ’category’ is ’clothes’.   
+• Round 1: Write a MongoDB query to select all documents in a collection where the field ’category’ is ’clothes’ and the ’brand’ field is not equal to ’Nike’.   
+• Round 2: Write a MongoDB query to select all documents in a collection where the field ’category’ is ’clothes’ and the ’brand’ field is not equal to ’Nike’, and the ’price’ field is greater than or equal to 100 and less than or equal to 500.   
+• Round 3: Write a MongoDB query to select all documents in a collection where the field ’category’ is ’clothes’ and the ’brand’ field is not equal to ’Nike’, and the ’price’ field is greater than or equal to 100 and less than or equal to 500, and the ’color’ field is either ’red’ or ’blue’. Additionally, sort the documents in descending order by the ’date added’ field and limit the result to the first 10 documents.
+
+# Example 2:
+
+• Round 0: Using Tensorflow, set up a model to predict the classification of a handwritten digit.   
+• Round 1: Using Tensorflow, set up a model to predict the classification of a handwritten digit with the constraint that the model must be trained using only 1000 samples from the MNIST dataset.   
+• Round 2: Using TensorFlow, set up a model to predict the classification of a handwritten digit with the constraint that the model must be trained using only 500 samples from the MNIST dataset. Additionally, implement transfer learning to incorporate the features learned from a pre-trained model.   
+• Round 3: Using TensorFlow and the MNIST dataset, develop a convolutional neural network (CNN) to accurately classify handwritten digits. However, in this new version of the task, you must limit your training to a maximum of 500 images. Furthermore, incorporate transfer learning by using a pre-trained model to extract features from the data and improve your model’s accuracy.
+
+# Example 3:
+
+• Round 0: Create a class in Java that can store a list of students and the courses they are enrolled in.   
+• Round 1: Create a Java program that manages a student database with courses, including options to add, remove, and search for students, as well as courses for each student. The program should also be able to display statistics on the number of students and courses.   
+Round 2: Develop a Java program that manages a student database containing courses and grades. Your program should allow users to add, remove, and search for students, as well as add or drop courses for each student. Furthermore, it should display statistics on the number of students and courses, and calculate the average grade for each student. Ensure that your program implements appropriate error-handling mechanisms. Round 3: Develop a Java program to manage a library system where users can check-in, check-out and search for books in the library. The system should allow users to add new books and delete existing ones from the library. The program should also provide statistics on the number of books checked-in and checked-out, and calculate the average reading time for each book. Ensure that your program implements appropriate error-handling mechanisms and enforces data integrity constraints such as not allowing users to check-out books that have already been checked-out.
+
+# E USING DIFFERENT EVOLUTION EXECUTION MODELS
+
+We explored using the open-source models (OSS) CodeLlama-Instruct-34B for generating evolved instructions. However, it demonstrated relatively low coding performance in response generation. To address this, we fine-tuned it using our code-alpaca dataset and utilized this model for response generation.
+
+# F INTERACTION EXAMPLES
+
+Table 6 7 8 showcases examples of interactions with our WizardCoder. The examples demonstrate that our model consistently generates accurate responses accompanied by clear explanations.

Through comprehensive experiments on five prominent code generation benchmarks, namely HumanEval, HumanEval+, MBPP, DS-1000, and MultiPL-E, our models showcase outstanding performance. They consistently outperform all other open-source Code LLMs by a significant margin. Remarkably, WizardCoder 15B even surpasses the well-known closed-source LLMs, including Anthropic’s Claude and Google’s Bard, on the HumanEval and HumanEval+ benchmarks. Additionally, WizardCoder 34B not only achieves a HumanEval score comparable to GPT3.5 (ChatGPT) but also surpasses it on the HumanEval+ benchmark.
