|
|
| ## Training Details |
|
|
| Vicuna v1.1 is fine-tuned from LLaMA with supervised instruction fine-tuning. |
| The training data is around 70K conversations collected from ShareGPT.com. |
| See more details in the "Training Details of Vicuna Models" section in the appendix of this [paper](https://arxiv.org/pdf/2306.05685.pdf). |
|
|
| ## Evaluation |
|
|
| Vicuna is evaluated with standard benchmarks, human preference, and LLM-as-a-judge. See more details in this [paper](https://arxiv.org/pdf/2306.05685.pdf) and [leaderboard](https://huggingface.co/spaces/lmsys/chatbot-arena-leaderboard). |
