llava-onevision-7b-ov-chat is our latest model specifically designed for chat scenarios. It is built upon llava-onevision-7b-ov and has undergone iterative DPO training with human preference, making it well-suited for chat applications.

Research by Tianyi Xiong indicates that our iterative DPO training method enhances the model's chat capabilities while preserving its instruction-following abilities.

For further details, please refer to our upcoming blog or paper.
