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: meta-llama/Meta-Llama-3-8B-Instruct

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.
