About Vicuna

Vicuna-13B is an open-source chatbot developed by fine-tuning the LLaMA language model on 70,000 user-shared conversations collected from ShareGPT. Created by the LMSYS Org research group, Vicuna aims to provide a high-quality conversational AI alternative to proprietary models like OpenAI's ChatGPT and Google Bard. The training process utilized PyTorch FSDP on 8 A100 GPUs over the course of one day, with a reported cost of approximately $300. Preliminary evaluations using GPT-4 as a judge suggest that Vicuna-13B achieves over 90% of the quality of ChatGPT, though this assessment is informal and not scientifically rigorous. The model is released under a non-commercial license, with both code and weights publicly available, and an online demo is provided for interactive testing. Vicuna is designed as a research tool and community-driven project, offering a foundation for further experimentation and development in open-source chatbot technology.
