|
- 7B parameters |
|
- 4-bit quantized |
|
- Based on version 1.1 |
|
- Used PR "More accurate Q4_0 and Q4_1 quantizations #896" (should be closer in quality to unquantized) |
|
- Uncensored variant is available, but it's based on version 1.0 |
|
- For q4_2, "Q4_2 ARM #1046" was used. Will update regularly if new changes are made. |
|
- **Choosing between q4_0, q4_1, and q4_2:** |
|
- 4_0 is the fastest. The quality is the poorest. |
|
- 4_1 is a lot slower. The quality is noticeably better. |
|
- 4_2 is almost as fast as 4_0 and about as good as 4_1 **on Apple Silicon**. On Intel/AMD it's hardly better or faster than 4_1. |

# Vicuna 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 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. |
|
(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 `"</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. |
