LLaVA Model Card
Model Details
Model type: LLaVA is an open-source chatbot trained by fine-tuning LLM on multimodal instruction-following data. It is an auto-regressive language model, based on the transformer architecture.
Base LLM: Qwen/Qwen1.5-32B-Chat
Model Description
Repository: https://github.com/LLaVA-VL/LLaVA-NeXT
Primary intended uses: The primary use of LLaVA is research on large multimodal models and chatbots. This is only for research exploration, and prohibited for commercial usage.
Primary intended users: The primary intended users of the model are researchers and hobbyists in computer vision, natural language processing, machine learning, and artificial intelligence.
