## InfiX.ai |
|
|
|
|
|
Welcome to **InfiX.ai**! We believe our research will eventually lead to decentralized Generative AI—a future where everyone can access, contribute to, and benefit from AI equally. |
|
|
Our Mission: **Generative AI for all, intelligence in every task.** |

### 🤖 Our Model Series |
|
|
#### 🔗 Model Fusion & Model Merging |
|
|
> **Model fusion** refers to the process of combining multiple trained models—often from different domains, architectures, or training datasets—into a single, more powerful model. The goal is to integrate their strengths and knowledge, improving performance, generalization, or efficiency. |
|
|
> **Model merging** is a specific type of model fusion that involves combining the internal parameters (typically weights) of two or more pretrained models to produce a single model that inherits knowledge from all sources. Unlike ensemble methods, model merging produces a single merged model rather than relying on multiple models at inference time. |

|
- [InfiFusion](https://huggingface.co/collections/InfiX-ai/infifusion-683c7d7f00c71614ba8ceb96): **InfiFusion** is a logit-level fusion pipeline based on Universal Logit Distillation, enhanced with Top-K filtering and logits standardization. It supports both pairwise and unified fusion strategies to balance performance and efficiency. |
|
|
- [InfiGFusion](https://huggingface.co/InfiX-ai/InfiGFusion-14B): **InfiGFusion** is a structure-aware extension that builds co-activation graphs from logits and aligns them via an efficient Gromov-Wasserstein loss approximation, capturing cross-dimension semantic dependencies for stronger reasoning. |
|
|
- [InfiFPO](https://huggingface.co/InfiX-ai/InfiFPO-14B): **InfiFPO** is a lightweight fusion method during the preference alignment phase that injects fused model behavior into preference learning, enabling richer signal during DPO-style fine-tuning. |

|
#### 🧠 Reasoning-Enhanced Low-Resource Training Pipeline |
|
|
|
|
|
- [InfiR](https://huggingface.co/papers/2502.11573): **InfiR** aims to advance AI systems by improving reasoning, reducing adoption barriers, and addressing privacy concerns through smaller model sizes. |
|
|
- [InfiR-FP8](https://huggingface.co/papers/2509.22536): **InfiR2** a fine-grained, hybrid-granularity FP8 quantization strategy to match BF16 performance while achieving up to a 22% reduction in training time and a 19% increase in throughput. |
|
|
- [InfiAlign](https://huggingface.co/papers/2508.05496): **InfiAlign** is a scalable and data-efficient post-training framework that combines supervised fine-tuning (SFT) and reinforcement learning (RL) with a high-quality data selection pipeline to enhance reasoning in large language models. |
|
|
- [InfiMMR](https://huggingface.co/papers/2505.23091): **InfiMMR** is a novel three-phase curriculum framework that systematically enhances multimodal reasoning capabilities in small language models through foundational reasoning activation, cross-modal adaptation, and multimodal reasoning enhancement. |

|
#### 🖥️ Advanced Vision-Native Agent for GUI Interaction |
|
|
- [InfiGUIAgent](https://huggingface.co/papers/2501.04575): **InfiGUIAgent** is a GUI agent that embeds native hierarchical and expectation-reflection reasoning through a unique two-stage supervised pipeline, enabling robust, multi-step GUI task automation. |
|
|
- [InfiGUI-R1](https://huggingface.co/papers/2504.14239v1): **InfiGUI-R1** is a GUI agent developed via the Actor2Reasoner framework, which evolves a reactive model into a deliberative reasoner capable of sophisticated planning and error recovery through spatial reasoning distillation and reinforcement learning. |
|
|
- [InfiGUI-G1](https://huggingface.co/papers/2508.05731): **InfiGUI-G1** is a multimodal GUI agent that employs Adaptive Exploration Policy Optimization (AEPO) to improve semantic alignment in GUI grounding. The novel training framework achieves up to **8.3%** relative improvement over baseline methods. |
