The former is slightly more accurate at the cost of a bit of performance. Most users should use one of the two.

It is an auto-regressive language model, based on the transformer architecture. **Model date:** Vicuna was trained between March 2023 and April 2023. **Organizations developing the model:** The Vicuna team with members from UC Berkeley, CMU, Stanford, and UC San Diego. **Paper or resources for more information:** https://vicuna.lmsys.org/ **License:** Apache License 2.0 **Where to send questions or comments about the model:** https://github.com/lm-sys/FastChat/issues ## 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. ## Training dataset 70K conversations collected from ShareGPT.com. (48k for the uncensored variant. 22k worth of garbage removed – see https://huggingface.co/datasets/anon8231489123/ShareGPT_Vicuna_unfiltered) ## Evaluation dataset A preliminary evaluation of the model quality is conducted by creating a set of 80 diverse questions and utilizing GPT-4 to judge the model outputs. See https://vicuna.lmsys.org/ for more details. ## 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 `""`. 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.
