LLaVA: Large Language and Vision Assistant
LLaVA represents a novel end-to-end trained large multimodal model that combines a vision encoder and Vicuna for general-purpose visual and language understanding, achieving impressive chat capabilities mimicking spirits of the multimodal GPT-4 and setting a new state-of-the-art accuracy on Science QA.

Abstract
Instruction tuning large language models (LLMs) using machine-generated instruction-following data has improved zero-shot capabilities on new tasks in the language domain, but the idea is less explored in the multimodal field.
- Multimodal Instruct Data. We present the first attempt to use language-only GPT-4 to generate multimodal language-image instruction-following data.
- LLaVA Model. We introduce LLaVA (Large Language-and-Vision Assistant), an end-to-end trained large multimodal model that connects a vision encoder and LLM for general-purpose visual and language understanding.
- Performance. Our early experiments show that LLaVA demonstrates impressive multimodel chat abilities, sometimes exhibiting the behaviors of multimodal GPT-4 on unseen images/instructions, and yields a 85.1% relative score compared with GPT-4 on a synthetic multimodal instruction-following dataset. When fine-tuned on Science QA, the synergy of LLaVA and GPT-4 achieves a new state-of-the-art accuracy of 92.53%.
- Open-source. We make GPT-4 generated visual instruction tuning data, our model and code base publicly available.
Multimodal Instrucion-Following Data
Based on the COCO dataset, we interact with langauge-only GPT-4, and collect 158K unique language-image instruction-following samples in total, including 58K in conversations, 23K in detailed description, and 77k in complex reasoning, respectively.

LLaVA: Large Language-and-Vision Assistant
LLaVa connects pre-trained CLIP ViT-L/14 visual encoder and large language model LLaMA, using a simple projection matrix. We consider a two-stage instruction-tuning procedure:
- Stage 1: Pre-training for Feature Alignment. Only the projection matrix is updated, based on a subset of CC3M.
- Stage 2: Fine-tuning End-to-End.. Both the projection matrix and LLM are updated for two different use senarios:
- Visual Chat: LLaVA is fine-tuned on our generated multimodal instruction-following data for daily user-oriented applications.
- Science QA: LLaVA is fine-tuned on this multimodal reasonsing dataset for the science domain.
Performance
Visual Chat: Towards building multimodal GPT-4 level chatbot
An evaluation dataset with 30 unseen images is constructed: each image is assocaited with three types of instructions: conversation, detailed description and complex reasoning. This leads to 90 new language-image instructions, on which we test LLaVA and GPT-4, and use GPT-4 to rate their responses from score 1 to 10. The summed score and relative score per type is reported. Overall, LLaVA achieves 85.1% relative score compared with GPT-4, indicating the effectinvess of the proposed self-instruct method in multimodal settings

Do you know who drew this painting?
LLaVA
The painting depicts a woman, commonly believed to be Mona Lisa, the famous artwork by Leonardo da Vinci. It is a portrait painting that showcases the woman's enigmatic smile and has become one of the most famous and iconic art pieces in the world. The original work is displayed in the Louvre Museum in Paris, and it is known for its intricate details, use of oil paint, and the artist's innovative techniques that contributed to its enduring appeal and mystery.
