| ## Model Card | |
| ### Model details | |
| Model type: Vicuna is an open-source chatbot trained by fine-tuning LLaMA on user-shared conversations collected from ShareGPT. It is an auto-regressive language model, based on the transformer architecture. | |
| Model date: Vicuna-13B-V1.1 weights was merged in April 2023. | |
| Organizations developing the model: The Vicuna team with members from UC Berkeley, CMU, Stanford, and UC San Diego. | |

| ### Intended use | |
| Primary intended uses: The primary use of Vicuna is research on large language models and chatbots. | |
| Primary intended users: The primary intended users of the model are researchers and hobbyists in natural language processing, machine learning, and artificial intelligence. | |
| ### Major updates of weights v1.1 | |
| Refactor the tokenization and separator. In Vicuna v1.1, the separator has been changed from "###" to the EOS token "</s>". This change makes it easier to determine the generation stop criteria and enables better compatibility with other libraries. | |
| Fix the supervised fine-tuning loss computation for better model quality. | |
