|
| | ## Training Details |
| |
|
| | Vicuna v1.5 is fine-tuned from Llama 2 with supervised instruction fine-tuning. |
| | The training data is around 125K 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). |
