Vicuna 13B 1.1 GPTQ 4bit 128g

This is a 4-bit GPTQ version of the Vicuna 13B 1.1 model.

It was created by merging the deltas provided in the above repo with the original Llama 13B model, using the code provided on their Github page.

It was then quantized to 4bit using GPTQ-for-LLaMa.

My Vicuna 1.1 model repositories

I have the following Vicuna 1.1 repositories available:

Provided files

Two model files are provided. Ideally use the safetensors file. Full details below:

Details of the files provided:

vicuna-13B-1.1-GPTQ-4bit-128g.safetensors
- safetensors format, with improved file security, created with the latest GPTQ-for-LLaMa code.
- Command to create:
  - python3 llama.py vicuna-13B-1.1-HF c4 --wbits 4 --true-sequential --act-order --groupsize 128 --save_safetensors vicuna-13B-1.1-GPTQ-4bit-128g.safetensors
vicuna-13B-1.1-GPTQ-4bit-128g.safetensors.no-act-order.pt`
- pt format file, created without the --act-order flag.
- This file may have slightly lower quality, but is included as it can be used without needing to compile the latest GPTQ-for-LLaMa code.
- It should hopefully therefore work with one-click-installers on Windows, which include the older GPTQ-for-LLaMa code.
- Command to create:
  - python3 llama.py vicuna-13B-1.1-HF c4 --wbits 4 --true-sequential --groupsize 128 --save_safetensors vicuna-13B-1.1-GPTQ-4bit-128g.no-act-order.pt

How to run in `text-generation-webui`

File vicuna-13B-1.1-GPTQ-4bit-128g.no-act-order.pt can be loaded the same as any other GPTQ file, without requiring any updates to oobaboogas text-generation-webui.

The safetensors model file was created with the latest GPTQ code, and uses --act-order to give the maximum possible quantisation quality, but this means it requires that the latest GPTQ-for-LLaMa is used inside the UI.

If you want to use the safetensors file and need to update GPTQ-for-LLaMa, here are the commands I used to clone the Triton branch of GPTQ-for-LLaMa, clone text-generation-webui, and install GPTQ into the UI:

git clone https://github.com/qwopqwop200/GPTQ-for-LLaMa
git clone https://github.com/oobabooga/text-generation-webui
mkdir -p text-generation-webui/repositories
ln -s GPTQ-for-LLaMa text-generation-webui/repositories/GPTQ-for-LLaMa

Then install this model into text-generation-webui/models and launch the UI as follows:

cd text-generation-webui
python server.py --model vicuna-13B-1.1-GPTQ-4bit-128g --wbits 4 --groupsize 128 --model_type Llama # add any other command line args you want

The above commands assume you have installed all dependencies for GPTQ-for-LLaMa and text-generation-webui. Please see their respective repositories for further information.

If you are on Windows, or cannot use the Triton branch of GPTQ for any other reason, you can instead use the CUDA branch:

git clone https://github.com/qwopqwop200/GPTQ-for-LLaMa -b cuda
cd GPTQ-for-LLaMa
python setup_cuda.py install

Then link that into text-generation-webui/repositories as described above.

Or just use vicuna-13B-1.1-GPTQ-4bit-128g.no-act-order.pt as mentioned above, which should work without any upgrades to text-generation-webui.

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.
