Humans have now entered a new era of interaction with the world, thanks to the incredible capabilities of Large Language Models (LLMs). LLMs like GPT-3, T5, and PaLM have taken the world by storm, mimicking human abilities such as reading, summarizing, and generating text.
In the field of Artificial Intelligence, researchers have been working on creating a general-purpose assistant that can understand and follow instructions involving both language and vision. This assistant would be able to complete real-world tasks with ease. To achieve this, they are developing language-augmented vision models that can perform tasks like classification, detection, segmentation, captioning, and visual generation.
OpenAI recently released GPT-4, a transformer model that powers the popular chatbot ChatGPT. GPT-4 comes with multimodal capabilities, making it a valuable addition to the list of LLMs. In a new research paper, the authors demonstrate the use of GPT-4 to generate multimodal language-image instruction-following data. They introduce LLaVA, a Large Language and Vision Assistant, which combines a vision encoder with Vicuna, an open-source chatbot, to achieve general-purpose visual and language understanding.
LLaVA aims to extend instruction tuning to the multimodal space, allowing users to complete tasks in real-time with the help of a visual assistant. The team behind LLaVA has made significant contributions in the following areas:
1. Multimodal instruction-following data: The team has developed a pipeline to convert image-text pairs into instruction-following format using GPT-4.
2. Large multimodal models: They have created a large multimodal model by connecting the visual encoder of CLIP with the language decoder LLaMA. This model is fine-tuned on generated instructional vision-language data.
3. Empirical study and SOTA performance: The team validates the effectiveness of user-generated data for LMM instruction tuning. They also achieve state-of-the-art performance on the Science QA multimodal reasoning dataset using GPT-4.
LLaVA is an open-source project, and the generated multimodal instruction data, codebase, model checkpoint, and visual chat demo are available on GitHub. It has demonstrated impressive chat abilities, outperforming GPT-4 on a synthetic multimodal instruction-following dataset. Fine-tuning LLaVA on Science QA leads to a new SOTA accuracy of 92.53%.
