16
+ ## Introduction
17
+
18
+ We are excited to announce the release of InternVL 2.0, the latest addition to the InternVL series of multimodal large language models. InternVL 2.0 features a variety of **instruction-tuned models**, ranging from 1 billion to 108 billion parameters. This repository contains the instruction-tuned InternVL2-4B model.
19
+
20
+ Compared to the state-of-the-art open-source multimodal large language models, InternVL 2.0 surpasses most open-source models. It demonstrates competitive performance on par with proprietary commercial models across various capabilities, including document and chart comprehension, infographics QA, scene text understanding and OCR tasks, scientific and mathematical problem solving, as well as cultural understanding and integrated multimodal capabilities.
21
+
22
+ InternVL 2.0 is trained with an 8k context window and utilizes training data consisting of long texts, multiple images, and videos, significantly improving its ability to handle these types of inputs compared to InternVL 1.5. For more details, please refer to our blog and GitHub.

64
+
65
+ - We simultaneously use InternVL and VLMEvalKit repositories for model evaluation. Specifically, the results reported for DocVQA, ChartQA, InfoVQA, TextVQA, MME, AI2D, MMBench, CCBench, MMVet, and SEED-Image were tested using the InternVL repository. OCRBench, RealWorldQA, HallBench, and MathVista were evaluated using the VLMEvalKit.
66
+
67
+ - For MMMU, we report both the original scores (left side: evaluated using the InternVL codebase for InternVL series models, and sourced from technical reports or webpages for other models) and the VLMEvalKit scores (right side: collected from the OpenCompass leaderboard).
68
+
69
+ - Please note that evaluating the same model using different testing toolkits like InternVL and VLMEvalKit can result in slight differences, which is normal. Updates to code versions and variations in environment and hardware can also cause minor discrepancies in results.

81
+ | Video-MME<br>w subs | - | 54.6 | 52.7 | 53.4 |
82
+
83
+ - We evaluate our models on MVBench and Video-MME by extracting 16 frames from each video, and each frame was resized to a 448x448 image.
84
+
85
+ Limitations: Although we have made efforts to ensure the safety of the model during the training process and to encourage the model to generate text that complies with ethical and legal requirements, the model may still produce unexpected outputs due to its size and probabilistic generation paradigm. For example, the generated responses may contain biases, discrimination, or other harmful content. Please do not propagate such content. We are not responsible for any consequences resulting from the dissemination of harmful information.
86
+
87
+ ## Quick Start
88
+
89
+ We provide an example code to run InternVL2-4B using `transformers`.
90
+
91
+ We also welcome you to experience the InternVL2 series models in our [online demo](https://internvl.opengvlab.com/). Currently, due to the limited GPU resources with public IP addresses, we can only deploy models up to a maximum of 26B. We will expand soon and deploy larger models to the online demo.
92
+
93
+ > Please use transformers==4.37.2 to ensure the model works normally.

333
+ ### Streaming output
334
+
335
+ Besides this method, you can also use the following code to get streamed output.
336
+
337
+ ```python
338
+ from transformers import TextIteratorStreamer
339
+ from threading import Thread
340
+
341
+ # Initialize the streamer
342
+ streamer = TextIteratorStreamer(tokenizer, skip_prompt=True, skip_special_tokens=True, timeout=10)
343
+ # Define the generation configuration
344
+ generation_config = dict(num_beams=1, max_new_tokens=1024, do_sample=False, streamer=streamer)
345
+ # Start the model chat in a separate thread
346
+ thread = Thread(target=model.chat, kwargs=dict(
347
+ tokenizer=tokenizer, pixel_values=pixel_values, question=question,
348
+ history=None, return_history=False, generation_config=generation_config,
349
+ ))
350
+ thread.start()
351
+
352
+ # Initialize an empty string to store the generated text
353
+ generated_text = ''
354
+ # Loop through the streamer to get the new text as it is generated
355
+ for new_text in streamer:
356
+ if new_text == model.conv_template.sep:
357
+ break
358
+ generated_text += new_text
359
+ print(new_text, end='', flush=True) # Print each new chunk of generated text on the same line
360
+ ```
361
+
362
+ ## Finetune
363
+
364
+ SWIFT from ModelScope community has supported the fine-tuning (Image/Video) of InternVL, please check [this link](https://github.com/modelscope/swift/blob/main/docs/source_en/Multi-Modal/internvl-best-practice.md) for more details.
365
+
366
+ ## Deployment
367
+
368
+ ### LMDeploy
369
+
370
+ LMDeploy is a toolkit for compressing, deploying, and serving LLM, developed by the MMRazor and MMDeploy teams.
371
+
372
+ ```sh
373
+ pip install lmdeploy
374
+ ```
375
+
376
+ LMDeploy abstracts the complex inference process of multi-modal Vision-Language Models (VLM) into an easy-to-use pipeline, similar to the Large Language Model (LLM) inference pipeline.
377
+
378
+ #### A 'Hello, world' example
379
+
380
+ ```python
381
+ from lmdeploy import pipeline, PytorchEngineConfig, ChatTemplateConfig
382
+ from lmdeploy.vl import load_image
383
+
384
+ model = 'OpenGVLab/InternVL2-4B'
385
+ system_prompt = '我是书生·万象,英文名是InternVL,是由上海人工智能实验室及多家合作单位联合开发的多模态大语言模型。'
386
+ image = load_image('https://raw.githubusercontent.com/open-mmlab/mmdeploy/main/tests/data/tiger.jpeg')
387
+ chat_template_config = ChatTemplateConfig('internvl-phi3')
388
+ chat_template_config.meta_instruction = system_prompt
389
+ pipe = pipeline(model, chat_template_config=chat_template_config,
390
+ backend_config=PytorchEngineConfig(session_len=8192))
391
+ response = pipe(('describe this image', image))
392
+ print(response.text)
393
+ ```
394
+
395
+ If `ImportError` occurs while executing this case, please install the required dependency packages as prompted.
396
+
397
+ #### Multi-images inference
398
+
399
+ When dealing with multiple images, you can put them all in one list. Keep in mind that multiple images will lead to a higher number of input tokens, and as a result, the size of the context window typically needs to be increased.
400
+
401
+ > Warning: Due to the scarcity of multi-image conversation data, the performance on multi-image tasks may be unstable, and it may require multiple attempts to achieve satisfactory results.
402
+
403
+ ```python
404
+ from lmdeploy import pipeline, PytorchEngineConfig, ChatTemplateConfig
405
+ from lmdeploy.vl import load_image
406
+ from lmdeploy.vl.constants import IMAGE_TOKEN
407
+
408
+ model = 'OpenGVLab/InternVL2-4B'
409
+ system_prompt = '我是书生·万象,英文名是InternVL,是由上海人工智能实验室及多家合作单位联合开发的多模态大语言模型。'
410
+ chat_template_config = ChatTemplateConfig('internvl-phi3')
411
+ chat_template_config.meta_instruction = system_prompt
412
+ pipe = pipeline(model, chat_template_config=chat_template_config,
413
+ backend_config=PytorchEngineConfig(session_len=8192))
414
+
415
+ image_urls=[
416
+ 'https://raw.githubusercontent.com/open-mmlab/mmdeploy/main/demo/resources/human-pose.jpg',
417
+ 'https://raw.githubusercontent.com/open-mmlab/mmdeploy/main/demo/resources/det.jpg'
418
+ ]
419
+
420
+ images = [load_image(img_url) for img_url in image_urls]
421
+ # Numbering images improves multi-image conversations
422
+ response = pipe((f'Image-1: {IMAGE_TOKEN}\nImage-2: {IMAGE_TOKEN}\ndescribe these two images', images))
423
+ print(response.text)
424
+ ```
425
+
426
+ #### Batch prompts inference
427
+
428
+ Conducting inference with batch prompts is quite straightforward; just place them within a list structure:
429
+
430
+ ```python
431
+ from lmdeploy import pipeline, PytorchEngineConfig, ChatTemplateConfig
432
+ from lmdeploy.vl import load_image
433
+
434
+ model = 'OpenGVLab/InternVL2-4B'
435
+ system_prompt = '我是书生·万象,英文名是InternVL,是由上海人工智能实验室及多家合作单位联合开发的多模态大语言模型。'
436
+ chat_template_config = ChatTemplateConfig('internvl-phi3')
437
+ chat_template_config.meta_instruction = system_prompt
438
+ pipe = pipeline(model, chat_template_config=chat_template_config,
439
+ backend_config=PytorchEngineConfig(session_len=8192))
440
+
441
+ image_urls=[
442
+ "https://raw.githubusercontent.com/open-mmlab/mmdeploy/main/demo/resources/human-pose.jpg",
443
+ "https://raw.githubusercontent.com/open-mmlab/mmdeploy/main/demo/resources/det.jpg"
444
+ ]
445
+ prompts = [('describe this image', load_image(img_url)) for img_url in image_urls]
446
+ response = pipe(prompts)
447
+ print(response)
448
+ ```
449
+
450
+ #### Multi-turn conversation
451
+
452
+ There are two ways to do the multi-turn conversations with the pipeline. One is to construct messages according to the format of OpenAI and use above introduced method, the other is to use the `pipeline.chat` interface.
453
+
454
+ ```python
455
+ from lmdeploy import pipeline, PytorchEngineConfig, ChatTemplateConfig, GenerationConfig
456
+ from lmdeploy.vl import load_image
457
+
458
+ model = 'OpenGVLab/InternVL2-4B'
459
+ system_prompt = '我是书生·万象,英文名是InternVL,是由上海人工智能实验室及多家合作单位联合开发的多模态大语言模型。'
460
+ chat_template_config = ChatTemplateConfig('internvl-phi3')
461
+ chat_template_config.meta_instruction = system_prompt
462
+ pipe = pipeline(model, chat_template_config=chat_template_config,
463
+ backend_config=PytorchEngineConfig(session_len=8192))
464
+
465
+ image = load_image('https://raw.githubusercontent.com/open-mmlab/mmdeploy/main/demo/resources/human-pose.jpg')
466
+ gen_config = GenerationConfig(top_k=40, top_p=0.8, temperature=0.8)
467
+ sess = pipe.chat(('describe this image', image), gen_config=gen_config)
468
+ print(sess.response.text)
469
+ sess = pipe.chat('What is the woman doing?', session=sess, gen_config=gen_config)
470
+ print(sess.response.text)
471
+ ```
472
+
473
+ #### Service
474
+
475
+ To deploy InternVL2 as an API, please configure the chat template config first. Create the following JSON file `chat_template.json`.
476
+
477
+ ```json
478
+ {
479
+ "model_name":"internlm2-phi3",
480
+ "meta_instruction":"我是书生·万象,英文名是InternVL,是由上海人工智能实验室及多家合作单位联合开发的多模态大语言模型。",
481
+ "stop_words":["<|end|>"]
482
+ }
483
+ ```
484
+
485
+ LMDeploy's `api_server` enables models to be easily packed into services with a single command. The provided RESTful APIs are compatible with OpenAI's interfaces. Below are an example of service startup:
486
+
487
+ ```shell
488
+ lmdeploy serve api_server OpenGVLab/InternVL2-4B --model-name InternVL2-4B --backend pytorch --server-port 23333 --chat-template chat_template.json
489
+ ```
490
+
491
+ To use the OpenAI-style interface, you need to install OpenAI:
492
+
493
+ ```shell
494
+ pip install openai
495
+ ```
496
+
497
+ Then, use the code below to make the API call:
498
+
499
+ ```python
500
+ from openai import OpenAI
501
+
502
+ client = OpenAI(api_key='YOUR_API_KEY', base_url='http://0.0.0.0:23333/v1')
503
+ model_name = client.models.list().data[0].id
504
+ response = client.chat.completions.create(
505
+ model="InternVL2-4B",
506
+ messages=[{
507
+ 'role':
508
+ 'user',
509
+ 'content': [{
510
+ 'type': 'text',
511
+ 'text': 'describe this image',
512
+ }, {
513
+ 'type': 'image_url',
514
+ 'image_url': {
515
+ 'url':
516
+ 'https://modelscope.oss-cn-beijing.aliyuncs.com/resource/tiger.jpeg',
517
+ },
518
+ }],
519
+ }],
520
+ temperature=0.8,
521
+ top_p=0.8)
522
+ print(response)
523
+ ```

624
+
625
+ 限制:尽管在训练过程中我们非常注重模型的安全性,尽力促使模型输出符合伦理和法律要求的文本,但受限于模型大小以及概率生成范式,模型可能会产生各种不符合预期的输出,例如回复内容包含偏见、歧视等有害内容,请勿传播这些内容。由于传播不良信息导致的任何后果,本项目不承担责任。
626
+
627
+ ## 快速启动
628
+
629
+ 我们提供了一个示例代码,用于使用 `transformers` 运行 InternVL2-4B。
630
+
631
+ 我们也欢迎你在我们的[在线demo](https://internvl.opengvlab.com/)中体验InternVL2的系列模型。目前,由于具备公网IP地址的GPU资源有限,我们目前只能部署最大到26B的模型。我们会在不久之后进行扩容,把更大的模型部署到在线demo上,敬请期待。
632
+
633
+ > 请使用 transformers==4.37.2 以确保模型正常运行。
634
+

+ 示例代码请[点击这里](#quick-start)。
636
+
637
+ ## 微调
638
+
639
+ 来自ModelScope社区的SWIFT已经支持对InternVL进行微调(图像/视频),详情请查看[此链接](https://github.com/modelscope/swift/blob/main/docs/source_en/Multi-Modal/internvl-best-practice.md)。

643
+ ### LMDeploy
644
+
645
+ LMDeploy 是由 MMRazor 和 MMDeploy 团队开发的用于压缩、部署和服务大语言模型(LLM)的工具包。
646
+
647
+ ```sh
648
+ pip install lmdeploy
649
+ ```
650
+
651
+ LMDeploy 将多模态视觉-语言模型(VLM)的复杂推理过程抽象为一个易于使用的管道,类似于大语言模型(LLM)的推理管道。
652
+
653
+ #### 一个“你好,世界”示例
654
+
655
+ ```python
656
+ from lmdeploy import pipeline, PytorchEngineConfig, ChatTemplateConfig
657
+ from lmdeploy.vl import load_image
658
+
659
+ model = 'OpenGVLab/InternVL2-4B'
660
+ system_prompt = '我是书生·万象,英文名是InternVL,是由上海人工智能实验室及多家合作单位联合开发的多模态大语言模型。'
661
+ image = load_image('https://raw.githubusercontent.com/open-mmlab/mmdeploy/main/tests/data/tiger.jpeg')
662
+ chat_template_config = ChatTemplateConfig('internvl-phi3')
663
+ chat_template_config.meta_instruction = system_prompt
664
+ pipe = pipeline(model, chat_template_config=chat_template_config,
665
+ backend_config=PytorchEngineConfig(session_len=8192))
666
+ response = pipe(('describe this image', image))
667
+ print(response.text)
668
+ ```
669
+
670
+ 如果在执行此示例时出现 `ImportError`,请按照提示安装所需的依赖包。
671
+
672
+ #### 多图像推理
673
+
674
+ 在处理多张图像时,可以将它们全部放入一个列表中。请注意,多张图像会导致输入 token 数量增加,因此通常需要增加上下文窗口的大小。
675
+
676
+ ```python
677
+ from lmdeploy import pipeline, PytorchEngineConfig, ChatTemplateConfig
678
+ from lmdeploy.vl import load_image
679
+ from lmdeploy.vl.constants import IMAGE_TOKEN
680
+
681
+ model = 'OpenGVLab/InternVL2-4B'
682
+ system_prompt = '我是书生·万象,英文名是InternVL,是由上海人工智能实验室及多家合作单位联合开发的多模态大语言模型。'
683
+ chat_template_config = ChatTemplateConfig('internvl-phi3')
684
+ chat_template_config.meta_instruction = system_prompt
685
+ pipe = pipeline(model, chat_template_config=chat_template_config,
686
+ backend_config=PytorchEngineConfig(session_len=8192))
687
+
688
+ image_urls=[
689
+ 'https://raw.githubusercontent.com/open-mmlab/mmdeploy/main/demo/resources/human-pose.jpg',
690
+ 'https://raw.githubusercontent.com/open-mmlab/mmdeploy/main/demo/resources/det.jpg'
691
+ ]
692
+
693
+ images = [load_image(img_url) for img_url in image_urls]
694
+ response = pipe((f'Image-1: {IMAGE_TOKEN}\nImage-2: {IMAGE_TOKEN}\ndescribe these two images', images))
695
+ print(response.text)
696
+ ```
697
+
698
+ #### 批量Prompt推理
699
+
700
+ 使用批量Prompt进行推理非常简单;只需将它们放在一个列表结构中:
701
+
702
+ ```python
703
+ from lmdeploy import pipeline, PytorchEngineConfig, ChatTemplateConfig
704
+ from lmdeploy.vl import load_image
705
+
706
+ model = 'OpenGVLab/InternVL2-4B'
707
+ system_prompt = '我是书生·万象,英文名是InternVL,是由上海人工智能实验室及多家合作单位联合开发的多模态大语言模型。'
708
+ chat_template_config = ChatTemplateConfig('internvl-phi3')
709
+ chat_template_config.meta_instruction = system_prompt
710
+ pipe = pipeline(model, chat_template_config=chat_template_config,
711
+ backend_config=PytorchEngineConfig(session_len=8192))
712
+
713
+ image_urls=[
714
+ "https://raw.githubusercontent.com/open-mmlab/mmdeploy/main/demo/resources/human-pose.jpg",
715
+ "https://raw.githubusercontent.com/open-mmlab/mmdeploy/main/demo/resources/det.jpg"
716
+ ]
717
+ prompts = [('describe this image', load_image(img_url)) for img_url in image_urls]
718
+ response = pipe(prompts)
719
+ print(response)
720
+ ```
721
+
722
+ #### 多轮对话
723
+
724
+ 使用管道进行多轮对话有两种方法。一种是根据 OpenAI 的格式构建消息并使用上述方法,另一种是使用 `pipeline.chat` 接口。
725
+
726
+ ```python
727
+ from lmdeploy import pipeline, PytorchEngineConfig, ChatTemplateConfig, GenerationConfig
728
+ from lmdeploy.vl import load_image
729
+
730
+ model = 'OpenGVLab/InternVL2-4B'
731
+ system_prompt = '我是书生·万象,英文名是InternVL,是由上海人工智能实验室及多家合作单位联合开发的多模态大语言模型。'
732
+ chat_template_config = ChatTemplateConfig('internvl-phi3')
733
+ chat_template_config.meta_instruction = system_prompt
734
+ pipe = pipeline(model, chat_template_config=chat_template_config,
735
+ backend_config=PytorchEngineConfig(session_len=8192))
736
+
737
+ image = load_image('https://raw.githubusercontent.com/open-mmlab/mmdeploy/main/demo/resources/human-pose.jpg')
738
+ gen_config = GenerationConfig(top_k=40, top_p=0.8, temperature=0.8)
739
+ sess = pipe.chat(('describe this image', image), gen_config=gen_config)
740
+ print(sess.response.text)
741
+ sess = pipe.chat('What is the woman doing?', session=sess, gen_config=gen_config)
742
+ print(sess.response.text)
743
+ ```
744
+
745
+ #### API部署
746
+
747
+ 为了将InternVL2部署成API,请先配置聊天模板配置文件。创建如下的 JSON 文件 `chat_template.json`。
748
+
749
+ ```json
750
+ {
751
+ "model_name":"internlm2-phi3",
752
+ "meta_instruction":"我是书生·万象,英文名是InternVL,是由上海人工智能实验室及多家合作单位联合开发的多模态大语言模型。",
753
+ "stop_words":["<|end|>"]
754
+ }
755
+ ```
756
+
757
+ LMDeploy 的 `api_server` 使模型能够通过一个命令轻松打包成服务。提供的 RESTful API 与 OpenAI 的接口兼容。以下是服务启动的示例:
758
+
759
+ ```shell
760
+ lmdeploy serve api_server OpenGVLab/InternVL2-4B --model-name InternVL2-4B --backend pytorch --server-port 23333 --chat-template chat_template.json
761
+ ```
762
+
763
+ 为了使用OpenAI风格的API接口,您需要安装OpenAI:
764
+
765
+ ```shell
766
+ pip install openai
767
+ ```
768
+
769
+ 然后,使用下面的代码进行API调用:
770
+
771
+ ```python
772
+ from openai import OpenAI
773
+
774
+ client = OpenAI(api_key='YOUR_API_KEY', base_url='http://0.0.0.0:23333/v1')
775
+ model_name = client.models.list().data[0].id
776
+ response = client.chat.completions.create(
777
+ model="InternVL2-4B",
778
+ messages=[{
779
+ 'role':
780
+ 'user',
781
+ 'content': [{
782
+ 'type': 'text',
783
+ 'text': 'describe this image',
784
+ }, {
785
+ 'type': 'image_url',
786
+ 'image_url': {
787
+ 'url':
788
+ 'https://modelscope.oss-cn-beijing.aliyuncs.com/resource/tiger.jpeg',
789
+ },
790
+ }],
791
+ }],
792
+ temperature=0.8,
793
+ top_p=0.8)
794
+ print(response)
795
+ ```

31
+ This is the configuration class to store the configuration of a [`Phi3Model`]. It is used to instantiate a Phi-3
32
+ model according to the specified arguments, defining the model architecture. Instantiating a configuration with the
33
+ defaults will yield a similar configuration to that of the
34
+ [microsoft/Phi-3-mini-4k-instruct](https://huggingface.co/microsoft/Phi-3-mini-4k-instruct).
35
+
36
+ Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
37
+ documentation from [`PretrainedConfig`] for more information.
38
+
39
+ Args:
40
+ vocab_size (`int`, *optional*, defaults to 32064):
41
+ Vocabulary size of the Phi-3 model. Defines the number of different tokens that can be represented by the
42
+ `inputs_ids` passed when calling [`Phi3Model`].
43
+ hidden_size (`int`, *optional*, defaults to 3072):
44
+ Dimension of the hidden representations.
45
+ intermediate_size (`int`, *optional*, defaults to 8192):
46
+ Dimension of the MLP representations.
47
+ num_hidden_layers (`int`, *optional*, defaults to 32):
48
+ Number of hidden layers in the Transformer decoder.
49
+ num_attention_heads (`int`, *optional*, defaults to 32):
50
+ Number of attention heads for each attention layer in the Transformer decoder.
51
+ num_key_value_heads (`int`, *optional*):
52
+ This is the number of key_value heads that should be used to implement Grouped Query Attention. If
53
+ `num_key_value_heads=num_attention_heads`, the model will use Multi Head Attention (MHA), if
54
+ `num_key_value_heads=1 the model will use Multi Query Attention (MQA) otherwise GQA is used. When
55
+ converting a multi-head checkpoint to a GQA checkpoint, each group key and value head should be constructed
56
+ by meanpooling all the original heads within that group. For more details checkout [this
57
+ paper](https://arxiv.org/pdf/2305.13245.pdf). If it is not specified, will default to
58
+ `num_attention_heads`.
59
+ resid_pdrop (`float`, *optional*, defaults to 0.0):
60
+ Dropout probability for mlp outputs.
61
+ embd_pdrop (`int`, *optional*, defaults to 0.0):
62
+ The dropout ratio for the embeddings.
63
+ attention_dropout (`float`, *optional*, defaults to 0.0):
64
+ The dropout ratio after computing the attention scores.
65
+ hidden_act (`str` or `function`, *optional*, defaults to `"silu"`):
66
+ The non-linear activation function (function or string) in the decoder.
67
+ max_position_embeddings (`int`, *optional*, defaults to 4096):
68
+ The maximum sequence length that this model might ever be used with.
69
+ original_max_position_embeddings (`int`, *optional*, defaults to 4096):
70
+ The maximum sequence length that this model was trained with. This is used to determine the size of the
71
+ original RoPE embeddings when using long scaling.
72
+ initializer_range (`float`, *optional*, defaults to 0.02):
73
+ The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
74
+ rms_norm_eps (`float`, *optional*, defaults to 1e-05):
75
+ The epsilon value used for the RMSNorm.
76
+ use_cache (`bool`, *optional*, defaults to `True`):
77
+ Whether or not the model should return the last key/values attentions (not used by all models). Only
78
+ relevant if `config.is_decoder=True`. Whether to tie weight embeddings or not.
79
+ tie_word_embeddings (`bool`, *optional*, defaults to `False`):
80
+ Whether to tie weight embeddings
81
+ rope_theta (`float`, *optional*, defaults to 10000.0):
82
+ The base period of the RoPE embeddings.
83
+ rope_scaling (`dict`, *optional*):
84
+ The scaling strategy for the RoPE embeddings. If `None`, no scaling is applied. If a dictionary, it must
85
+ contain the following keys: `type`, `short_factor` and `long_factor`. The `type` must be either `su` or `yarn` and
86
+ the `short_factor` and `long_factor` must be lists of numbers with the same length as the hidden size
87
+ divided by the number of attention heads divided by 2.
88
+ bos_token_id (`int`, *optional*, defaults to 1):
89
+ The id of the "beginning-of-sequence" token.
90
+ eos_token_id (`int`, *optional*, defaults to 32000):
91
+ The id of the "end-of-sequence" token.
92
+ pad_token_id (`int`, *optional*, defaults to 32000):
93
+ The id of the padding token.
94
+ sliding_window (`int`, *optional*):
95
+ Sliding window attention window size. If `None`, no sliding window is applied.
96
+
97
+ Example:
98
+
99
+ ```python
100
+ >>> from transformers import Phi3Model, Phi3Config
101
+
102
+ >>> # Initializing a Phi-3 style configuration
