## Model Summary
The LLaVA-NeXT-Video models are 7/72B parameter models trained on [LLaVA-NeXT-Video-178K](https://huggingface.co/datasets/lmms-lab/LLaVA-NeXT-Video-SFT-Data), based on Qwen2 language model with a context window of 32K tokens.
This model support at most 110 frames.

## Use
### Intended use
The model was trained on [LLaVA-NeXT-Video-178K](https://huggingface.co/datasets/lmms-lab/LLaVA-NeXT-Video-SFT-Data) and have the ability to interact with videos.
**Feel free to share your generations in the Community tab!**
