|
GPTQ models are currently supported on Linux (NVidia/AMD) and Windows (NVidia only). macOS users: please use GGUF models. |
|
|
|
These GPTQ models are known to work in the following inference servers/webuis. |
|
|
|
- [text-generation-webui](https://github.com/oobabooga/text-generation-webui) |
|
- [KoboldAI United](https://github.com/henk717/koboldai) |
|
- [LoLLMS Web UI](https://github.com/ParisNeo/lollms-webui) |
|
- [Hugging Face Text Generation Inference (TGI)](https://github.com/huggingface/text-generation-inference) |
|

|
## Provided files, and GPTQ parameters |
|
|
|
Multiple quantisation parameters are provided, to allow you to choose the best one for your hardware and requirements. |
|
|
|
Each separate quant is in a different branch. See below for instructions on fetching from different branches. |
|
|
|
Most GPTQ files are made with AutoGPTQ. Mistral models are currently made with Transformers. |
|
|
|
<details> |
|
<summary>Explanation of GPTQ parameters</summary> |
|
|
|
- Bits: The bit size of the quantised model. |
|
- GS: GPTQ group size. Higher numbers use less VRAM, but have lower quantisation accuracy. "None" is the lowest possible value. |
|
- Act Order: True or False. Also known as `desc_act`. True results in better quantisation accuracy. Some GPTQ clients have had issues with models that use Act Order plus Group Size, but this is generally resolved now. |
|
- Damp %: A GPTQ parameter that affects how samples are processed for quantisation. 0.01 is default, but 0.1 results in slightly better accuracy. |
|
- GPTQ dataset: The calibration dataset used during quantisation. Using a dataset more appropriate to the model's training can improve quantisation accuracy. Note that the GPTQ calibration dataset is not the same as the dataset used to train the model - please refer to the original model repo for details of the training dataset(s). |
|
- Sequence Length: The length of the dataset sequences used for quantisation. Ideally this is the same as the model sequence length. For some very long sequence models (16+K), a lower sequence length may have to be used. Note that a lower sequence length does not limit the sequence length of the quantised model. It only impacts the quantisation accuracy on longer inference sequences. |
|
- ExLlama Compatibility: Whether this file can be loaded with ExLlama, which currently only supports Llama and Mistral models in 4-bit. |
|

## How to download, including from branches |
|
|
|
### In text-generation-webui |
|
|
|
To download from the `main` branch, enter `TheBloke/Mixtral-8x7B-Instruct-v0.1-GPTQ` in the "Download model" box. |
|
|
|
To download from another branch, add `:branchname` to the end of the download name, eg `TheBloke/Mixtral-8x7B-Instruct-v0.1-GPTQ:gptq-4bit-128g-actorder_True` |
|
|
|
### From the command line |
|
|
|
I recommend using the `huggingface-hub` Python library: |
|
|
|
```shell |
|
pip3 install huggingface-hub |
|
``` |
|
|
|
To download the `main` branch to a folder called `Mixtral-8x7B-Instruct-v0.1-GPTQ`: |
|
|
|
```shell |
|
mkdir Mixtral-8x7B-Instruct-v0.1-GPTQ |
|
huggingface-cli download TheBloke/Mixtral-8x7B-Instruct-v0.1-GPTQ --local-dir Mixtral-8x7B-Instruct-v0.1-GPTQ --local-dir-use-symlinks False |
|
``` |
|
|
|
To download from a different branch, add the `--revision` parameter: |
|
|
|
```shell |
|
mkdir Mixtral-8x7B-Instruct-v0.1-GPTQ |
|
huggingface-cli download TheBloke/Mixtral-8x7B-Instruct-v0.1-GPTQ --revision gptq-4bit-128g-actorder_True --local-dir Mixtral-8x7B-Instruct-v0.1-GPTQ --local-dir-use-symlinks False |
|
``` |
|
|
|
<details> |
|
<summary>More advanced huggingface-cli download usage</summary> |
|
|
|
If you remove the `--local-dir-use-symlinks False` parameter, the files will instead be stored in the central Hugging Face cache directory (default location on Linux is: `~/.cache/huggingface`), and symlinks will be added to the specified `--local-dir`, pointing to their real location in the cache. This allows for interrupted downloads to be resumed, and allows you to quickly clone the repo to multiple places on disk without triggering a download again. The downside, and the reason why I don't list that as the default option, is that the files are then hidden away in a cache folder and it's harder to know where your disk space is being used, and to clear it up if/when you want to remove a download model. |
|
|
|
The cache location can be changed with the `HF_HOME` environment variable, and/or the `--cache-dir` parameter to `huggingface-cli`. |
|
|
|
For more documentation on downloading with `huggingface-cli`, please see: [HF -> Hub Python Library -> Download files -> Download from the CLI](https://huggingface.co/docs/huggingface_hub/guides/download#download-from-the-cli). |
|
|
|
To accelerate downloads on fast connections (1Gbit/s or higher), install `hf_transfer`: |
|
|
|
```shell |
|
pip3 install hf_transfer |
|
``` |
|
|
|
And set environment variable `HF_HUB_ENABLE_HF_TRANSFER` to `1`: |
|
|
|
```shell |
|
mkdir Mixtral-8x7B-Instruct-v0.1-GPTQ |
|
HF_HUB_ENABLE_HF_TRANSFER=1 huggingface-cli download TheBloke/Mixtral-8x7B-Instruct-v0.1-GPTQ --local-dir Mixtral-8x7B-Instruct-v0.1-GPTQ --local-dir-use-symlinks False |
|
``` |
|
|
|
Windows Command Line users: You can set the environment variable by running `set HF_HUB_ENABLE_HF_TRANSFER=1` before the download command. |
|
</details> |
|
|
|
### With `git` (**not** recommended) |
|
|
|
To clone a specific branch with `git`, use a command like this: |
|
|
|
```shell |
|
git clone --single-branch --branch gptq-4bit-128g-actorder_True https://huggingface.co/TheBloke/Mixtral-8x7B-Instruct-v0.1-GPTQ |
|
``` |
|
|
|
Note that using Git with HF repos is strongly discouraged. It will be much slower than using `huggingface-hub`, and will use twice as much disk space as it has to store the model files twice (it stores every byte both in the intended target folder, and again in the `.git` folder as a blob.) |

|
## How to easily download and use this model in [text-generation-webui](https://github.com/oobabooga/text-generation-webui) |
|
|
|
Please make sure you're using the latest version of [text-generation-webui](https://github.com/oobabooga/text-generation-webui). |
|
|
|
It is strongly recommended to use the text-generation-webui one-click-installers unless you're sure you know how to make a manual install. |
|
|
|
1. Click the **Model tab**. |
|
2. Under **Download custom model or LoRA**, enter `TheBloke/Mixtral-8x7B-Instruct-v0.1-GPTQ`. |
|
|
|
- To download from a specific branch, enter for example `TheBloke/Mixtral-8x7B-Instruct-v0.1-GPTQ:gptq-4bit-128g-actorder_True` |
|
- see Provided Files above for the list of branches for each option. |
|
|
|
3. Click **Download**. |
|
4. The model will start downloading. Once it's finished it will say "Done". |
|
5. In the top left, click the refresh icon next to **Model**. |
|
6. In the **Model** dropdown, choose the model you just downloaded: `Mixtral-8x7B-Instruct-v0.1-GPTQ` |
|
7. The model will automatically load, and is now ready for use! |
|
8. If you want any custom settings, set them and then click **Save settings for this model** followed by **Reload the Model** in the top right. |
|
|
|
- Note that you do not need to and should not set manual GPTQ parameters any more. These are set automatically from the file `quantize_config.json`. |
|
|
|
9. Once you're ready, click the **Text Generation** tab and enter a prompt to get started! |
|

<!-- README_GPTQ.md-use-from-tgi start --> |
|
## Serving this model from Text Generation Inference (TGI) |
|
|
|
It's recommended to use TGI version 1.1.0 or later. The official Docker container is: `ghcr.io/huggingface/text-generation-inference:1.1.0` |
|
|
|
Example Docker parameters: |
|
|
|
```shell |
|
--model-id TheBloke/Mixtral-8x7B-Instruct-v0.1-GPTQ --port 3000 --quantize gptq --max-input-length 3696 --max-total-tokens 4096 --max-batch-prefill-tokens 4096 |
|
``` |
|
|
|
Example Python code for interfacing with TGI (requires huggingface-hub 0.17.0 or later): |
|
|
|
```shell |
|
pip3 install huggingface-hub |
|
``` |
|
|
|
```python |
|
from huggingface_hub import InferenceClient |
|
|
|
endpoint_url = "https://your-endpoint-url-here" |
|
|
|
prompt = "Tell me about AI" |
|
prompt_template=f'''<s>[INST] {prompt} [/INST] |
|
''' |
|
|
|
client = InferenceClient(endpoint_url) |
|
response = client.text_generation(prompt, |
|
max_new_tokens=128, |
|
do_sample=True, |
|
temperature=0.7, |
|
top_p=0.95, |
|
top_k=40, |
|
repetition_penalty=1.1) |
|
|
|
print(f"Model output: {response}") |
|
``` |
|
<!-- README_GPTQ.md-use-from-tgi end --> |
|
<!-- README_GPTQ.md-use-from-python start --> |
|
## Python code example: inference from this GPTQ model |
|
|
|
### Install the necessary packages |
|
|
|
Requires: Transformers 4.33.0 or later, Optimum 1.12.0 or later, and AutoGPTQ 0.4.2 or later. |
|
|
|
```shell |
|
pip3 install --upgrade transformers optimum |
|
# If using PyTorch 2.1 + CUDA 12.x: |
|
pip3 install --upgrade auto-gptq |
|
# or, if using PyTorch 2.1 + CUDA 11.x: |
|
pip3 install --upgrade auto-gptq --extra-index-url https://huggingface.github.io/autogptq-index/whl/cu118/ |
|
``` |
|
|
|
If you are using PyTorch 2.0, you will need to install AutoGPTQ from source. Likewise if you have problems with the pre-built wheels, you should try building from source: |
|
|
|
```shell |
|
pip3 uninstall -y auto-gptq |
|
git clone https://github.com/PanQiWei/AutoGPTQ |
|
cd AutoGPTQ |
|
git checkout v0.5.1 |
|
pip3 install . |
|
``` |
|
|
|
### Example Python code |
|
|
|
```python |
|
from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline |
|
|
|
model_name_or_path = "TheBloke/Mixtral-8x7B-Instruct-v0.1-GPTQ" |
|
# To use a different branch, change revision |
|
# For example: revision="gptq-4bit-128g-actorder_True" |
|
model = AutoModelForCausalLM.from_pretrained(model_name_or_path, |
|
device_map="auto", |
|
trust_remote_code=False, |
|
revision="main") |
|
|
|
tokenizer = AutoTokenizer.from_pretrained(model_name_or_path, use_fast=True) |
|
|
|
prompt = "Tell me about AI" |
|
prompt_template=f'''<s>[INST] {prompt} [/INST] |
|
''' |
|
|
|
print("\n\n*** Generate:") |
|
|
|
input_ids = tokenizer(prompt_template, return_tensors='pt').input_ids.cuda() |
|
output = model.generate(inputs=input_ids, temperature=0.7, do_sample=True, top_p=0.95, top_k=40, max_new_tokens=512) |
|
print(tokenizer.decode(output[0])) |
|
|
|
# Inference can also be done using transformers' pipeline |
|
|
|
print("*** Pipeline:") |
|
pipe = pipeline( |
|
"text-generation", |
|
model=model, |
|
tokenizer=tokenizer, |
|
max_new_tokens=512, |
|
do_sample=True, |
|
temperature=0.7, |
|
top_p=0.95, |
|
top_k=40, |
|
repetition_penalty=1.1 |
|
) |
|
|
|
print(pipe(prompt_template)[0]['generated_text']) |
|

## Warning |
|
This repo contains weights that are compatible with [vLLM](https://github.com/vllm-project/vllm) serving of the model as well as Hugging Face [transformers](https://github.com/huggingface/transformers) library. It is based on the original Mixtral [torrent release](magnet:?xt=urn:btih:5546272da9065eddeb6fcd7ffddeef5b75be79a7&dn=mixtral-8x7b-32kseqlen&tr=udp%3A%2F%http://2Fopentracker.i2p.rocks%3A6969%2Fannounce&tr=http%3A%2F%http://2Ftracker.openbittorrent.com%3A80%2Fannounce), but the file format and parameter names are different. Please note that model cannot (yet) be instantiated with HF. |
|
|
|
## Instruction format |
|
|
|
This format must be strictly respected, otherwise the model will generate sub-optimal outputs. |
|
|
|
The template used to build a prompt for the Instruct model is defined as follows: |
|
``` |
|
<s> [INST] Instruction [/INST] Model answer</s> [INST] Follow-up instruction [/INST] |
|
``` |
|
Note that `<s>` and `</s>` are special tokens for beginning of string (BOS) and end of string (EOS) while [INST] and [/INST] are regular strings. |
|
|
|
As reference, here is the pseudo-code used to tokenize instructions during fine-tuning: |
|
```python |
|
def tokenize(text): |
|
return tok.encode(text, add_special_tokens=False) |
|
|
|
[BOS_ID] + |
|
tokenize("[INST]") + tokenize(USER_MESSAGE_1) + tokenize("[/INST]") + |
|
tokenize(BOT_MESSAGE_1) + [EOS_ID] + |
|
… |
|
tokenize("[INST]") + tokenize(USER_MESSAGE_N) + tokenize("[/INST]") + |
|
tokenize(BOT_MESSAGE_N) + [EOS_ID] |
|
``` |
|
|
|
In the pseudo-code above, note that the `tokenize` method should not add a BOS or EOS token automatically, but should add a prefix space. |
|
|
|
## Run the model |
|
|
|
```python |
|
from transformers import AutoModelForCausalLM, AutoTokenizer |
|
|
|
model_id = "mistralai/Mixtral-8x7B-Instruct-v0.1" |
|
tokenizer = AutoTokenizer.from_pretrained(model_id) |
|
|
|
model = AutoModelForCausalLM.from_pretrained(model_id) |
|
|
|
text = "Hello my name is" |
|
inputs = tokenizer(text, return_tensors="pt") |
|
|
|
outputs = model.generate(**inputs, max_new_tokens=20) |
|
print(tokenizer.decode(outputs[0], skip_special_tokens=True)) |
|
``` |
|
|
|
By default, transformers will load the model in full precision. Therefore you might be interested to further reduce down the memory requirements to run the model through the optimizations we offer in HF ecosystem: |
|
|
|
### In half-precision |
|
|
|
Note `float16` precision only works on GPU devices |

## Limitations |
|
|
|
The Mixtral-8x7B Instruct model is a quick demonstration that the base model can be easily fine-tuned to achieve compelling performance. |
|
It does not have any moderation mechanisms. We're looking forward to engaging with the community on ways to |
|
make the model finely respect guardrails, allowing for deployment in environments requiring moderated outputs. |
