||
|
|
|
||
|
|
## 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 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.

|
## 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.
|
||
|
|
|
||
|
|
## 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 `"</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.
