Play with the model on the LLaVA OneVision Chat.
Table of Contents Model SummaryThe LLaVA-OneVision models are 0.5/7/72B parameter models trained on LLaVA-OneVision, based on Qwen2 language model with a context window of 32K tokens.
The model was trained on LLaVA-OneVision Dataset and have the ability to interact with images, multi-image and videos.
Feel free to share your generations in the Community tab!
GenerationWe provide the simple generation process for using our model. For more details, you could refer to Github.
