LLaVA-RLHF Model Card

Model details

Model type: LLaVA-RLHF represents a novel aligned end-to-end trained large multimodal model that combines a CLIP vision encoder and Vicuna for general-purpose visual and language understanding, achieving impressive visual reasoning and perception capabilities mimicking spirits of the multimodal GPT-4. Via Factually Augmented RLHF, LLaVA-RLHF is presented to be more helpful and less hallucinated than LLaVA or other open-sourced LMMs.

Usage: NOTE: The RLHFed model is trained with LoRA and the bfloat16 data type. Users have to apply the PEFT-LoRA on the LLaVA-SFT+ model.
