## 🔥 Latest Update
|
|
* [2024/12/12] Our [first version](https://huggingface.co/collections/menglc/slimm-675bd737c2965037a6b52d05) is out! We release a strong 0.5B baseline model [SliMM-Qwen2-0.5B](https://huggingface.co/menglc/SliMM-Qwen2-0.5B) and advanced baseline [SliMM-DeepStackM-Qwen2-0.5B](https://huggingface.co/menglc/SliMM-DeepStackM-Qwen2-0.5B). We release a strong 2B model [SliMM-DeepStackE-Qwen2VL-2B](https://huggingface.co/menglc/SliMM-DeepStackE-Qwen2VL-2B) continous fine-tuned from Qwen2VL-2B, which save 4x fewer visual tokens for LLM with. Training scrips are avaliable [here]()!

## Introduction
|
|
|
|
* **Advanced Techniques**: We incorporate native dynamic resolution, as used in Qwen2-VL, for high-resolution visual encoding, replacing the previous cumbersome Multi-Crop/AnyRes methods. Moreover, building on DeepStack [1], we maintain the same principle of interting stacked visual tokens into **multiple layers** of the LLMs. We propose two enhanced versions for native resolution vision encoding: DeepStack-MidLayers, which improves performance with negligible additional FLOPs by stacking multi-level visual tokens from the middle layers of the vision encoder, and DeepStack-Efficient, which reduces visual token usage while maintaining high performance.
|
|
* **Seamless Integration**: Easily use LLaVA-format training data in our codebase.
|
|
* **Training Efficiency**: Fine-tuning on the 748K LLaVA-Next-DATA for on epoch takes only 4 hours for 0.5/2B Qwen2 and 6 hours for a 7B on 8xH100, which is more than 2x faster than LLaVA-OV codebase.
|
|
* **Strong Baseline Model for Small LMMs**: We establish a robust baseline using widely-used public available datasets, including LCS-758K (Stage-1), LLaVA-OV-MidStage (Stage 1.5), and LLaVA-OneVision SI (Stage 2).

## Quick Start
|
|
|
|
|
|
```bash
|
|
git clone https://github.com/MengLcool/SliMM.git
|
|
cd SliMM
|
|
pip install -e .
|
|
```
|
|
|
|
```Python
