Model Summary

The LLaVA-NeXT-Video models are 7/72B parameter models trained on LLaVA-NeXT-Video-178K and LLaVA-OneVision Dataset, based on Qwen2 language model with a context window of 32K tokens.

This model support at most 64 frames.

Repository: LLaVA-VL/LLaVA-NeXT
Point of Contact: Yuanhan Zhang
Languages: English, Chinese

Use

Intended use

The model was trained on LLaVA-NeXT-Video-178K and LLaVA-OneVision Dataset, having the ability to interact with images, multi-image and videos, but specific to videos.

Feel free to share your generations in the Community tab!

Generation

We provide the simple generation process for using our model. For more details, you could refer to Github.
