Vicuna
About
The Vicuna large language model (LLM) family, developed by LMSYS, consists of open-source chat assistants fine-tuned from the LLaMA family, specifically LLaMA and Llama 2, using a diverse dataset from ShareGPT 145. Designed to deliver detailed and structured responses rivaling leading commercial models like ChatGPT and Google Bard, the Vicuna models vary in size and context window length, such as 7B, 13B parameters, and 16k tokens 1. They are primarily intended for research, with their code, weights, and demos available under a non-commercial license, ensuring accessibility for experimentation and development 4. Initial evaluations found these models reaching about 90% of ChatGPT's performance, prompting ongoing refinement 1.
