+## Licensing
+
+The creator of the source model has listed its license as `cc`, and this quantization has therefore used that same license.
+
+As this model is based on Llama 2, it is also subject to the Meta Llama 2 license terms, and the license files for that are additionally included. It should therefore be considered as being claimed to be licensed under both licenses. I contacted Hugging Face for clarification on dual licensing but they do not yet have an official position. Should this change, or should Meta provide any feedback on this situation, I will update this section accordingly.
+
+In the meantime, any questions regarding licensing, and in particular how these two licenses might interact, should be directed to the original model repository: [medalpaca's Medalpaca 13B](https://huggingface.co/medalpaca/medalpaca-13b).

+## 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.
+
+All recent GPTQ files are made with AutoGPTQ, and all files in non-main branches are made with AutoGPTQ. Files in the `main` branch which were uploaded before August 2023 were made with GPTQ-for-LLaMa.
+
+<details>
+  <summary>Explanation of GPTQ parameters</summary>
 
-This is a [GPTQ-for-LLaMa](https://github.com/qwopqwop200/GPTQ-for-LLaMa) 4bit quantisation of [medalpaca-13b](https://huggingface.co/medalpaca/medalpaca-13b).
+- 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 dataset used for quantisation. Using a dataset more appropriate to the model's training can improve quantisation accuracy. Note that the GPTQ 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 models in 4-bit.
 
-## GIBBERISH OUTPUT IN `text-generation-webui`?

-Please read the Provided Files section below. You should use `medalpaca-13B-GPTQ-4bit-128g.no-act-order.safetensors` unless you are able to use the latest Triton branch of GPTQ-for-LLaMa.
+| Branch | Bits | GS | Act Order | Damp % | GPTQ Dataset | Seq Len | Size | ExLlama | Desc |
+| ------ | ---- | -- | --------- | ------ | ------------ | ------- | ---- | ------- | ---- |

+## How to download from branches
+
+- In text-generation-webui, you can add `:branch` to the end of the download name, eg `TheBloke/medalpaca-13B-GPTQ:main`
+- With Git, you can clone a branch with:
+```
+git clone --single-branch --branch main https://huggingface.co/TheBloke/medalpaca-13B-GPTQ
+```
+- In Python Transformers code, the branch is the `revision` parameter; see below.

-
-## Provided files
-
-Two files are provided. **The second file will not work unless you use a recent version of the Triton branch of GPTQ-for-LLaMa**
-
-Specifically, the second file uses `--act-order` for maximum quantisation quality and will not work with oobabooga's fork of GPTQ-for-LLaMa. Therefore at this time it will also not work with the CUDA branch of GPTQ-for-LLaMa, or `text-generation-webui` one-click installers.
-
-Unless you are able to use the latest GPTQ-for-LLaMa code, please use `medalpaca-13B-GPTQ-4bit-128g.no-act-order.safetensors`
-
-* `medalpaca-13B-GPTQ-4bit-128g.no-act-order.safetensors`
-  * Works with all versions of GPTQ-for-LLaMa code, both Triton and CUDA branches
-  * Works with text-generation-webui one-click-installers
-  * Works on Windows
-  * Parameters: Groupsize = 128g. No act-order.
-  * Command used to create the GPTQ:
-    ```
-    CUDA_VISIBLE_DEVICES=0 python3 llama.py medalpaca-13b c4 --wbits 4 --true-sequential --groupsize 128 --save_safetensors medalpaca-13B-GPTQ-4bit-128g.no-act-order.safetensors
-    ```
-* `medalpaca-13B-GPTQ-4bit-128g.safetensors`
-  * Only works with the latest Triton branch of GPTQ-for-LLaMa
-  * **Does not** work with text-generation-webui one-click-installers
-  * **Does not** work on Windows
-  * Parameters: Groupsize = 128g. act-order.
-  * Offers highest quality quantisation, but requires recent GPTQ-for-LLaMa code
-  * Command used to create the GPTQ:
-    ```
-    CUDA_VISIBLE_DEVICES=0 python3 llama.py medalpaca-13b c4 --wbits 4 --true-sequential --act-order --groupsize 128 --save_safetensors medalpaca-13B-GPTQ-4bit-128g.safetensors
-    ```
-
-## How to run in `text-generation-webui`
-
-File `medalpaca-13B-GPTQ-4bit-128g.no-act-order.safetensors` can be loaded the same as any other GPTQ file, without requiring any updates to [oobaboogas text-generation-webui](https://github.com/oobabooga/text-generation-webui).
-
-[Instructions on using GPTQ 4bit files in text-generation-webui are here](https://github.com/oobabooga/text-generation-webui/wiki/GPTQ-models-\(4-bit-mode\)).
-
-The other `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 act-order `safetensors` file and need to update the Triton branch of 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:
+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: `medalpaca-13B-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!

+## How to use this GPTQ model from Python code
+
+### Install the necessary packages
+
+Requires: Transformers 4.32.0 or later, Optimum 1.12.0 or later, and AutoGPTQ 0.4.2 or later.
+
+```shell
+pip3 install transformers>=4.32.0 optimum>=1.12.0
+pip3 install auto-gptq --extra-index-url https://huggingface.github.io/autogptq-index/whl/cu118/  # Use cu117 if on CUDA 11.7
 ```
-# Clone text-generation-webui, if you don't already have it
-git clone https://github.com/oobabooga/text-generation-webui
-# Make a repositories directory
-mkdir text-generation-webui/repositories
-cd text-generation-webui/repositories
-# Clone the latest GPTQ-for-LLaMa code inside text-generation-webui
-git clone https://github.com/qwopqwop200/GPTQ-for-LLaMa
+
+If you have problems installing AutoGPTQ using the pre-built wheels, install it from source instead:
+
+```shell
+pip3 uninstall -y auto-gptq
+git clone https://github.com/PanQiWei/AutoGPTQ
+cd AutoGPTQ
+pip3 install .
 ```
 
-Then install this model into `text-generation-webui/models` and launch the UI as follows:
+### For CodeLlama models only: you must use Transformers 4.33.0 or later.
+
+If 4.33.0 is not yet released when you read this, you will need to install Transformers from source:
+```shell
+pip3 uninstall -y transformers
+pip3 install git+https://github.com/huggingface/transformers.git
 ```
-cd text-generation-webui
-python server.py --model medalpaca-13B-GPTQ-4bit --wbits 4 --groupsize 128 --model_type Llama # add any other command line args you want
+
+### You can then use the following code
+
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline
+
+model_name_or_path = "TheBloke/medalpaca-13B-GPTQ"
+# To use a different branch, change revision
+# For example: revision="main"

+## Compatibility
+
+The files provided are tested to work with AutoGPTQ, both via Transformers and using AutoGPTQ directly. They should also work with [Occ4m's GPTQ-for-LLaMa fork](https://github.com/0cc4m/KoboldAI).
 
-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.
+[ExLlama](https://github.com/turboderp/exllama) is compatible with Llama models in 4-bit. Please see the Provided Files table above for per-file compatibility.
 
-If you can't update GPTQ-for-LLaMa to the latest Triton branch, or don't want to, you can use `medalpaca-13B-GPTQ-4bit-128g.no-act-order.safetensors` as mentioned above, which should work without any upgrades to text-generation-webui.
+[Huggingface Text Generation Inference (TGI)](https://github.com/huggingface/text-generation-inference) is compatible with all GPTQ models.

+`medalpaca-13b` is a large language model specifically fine-tuned for medical domain tasks. 
+It is based on LLaMA (Large Language Model Meta AI) and contains 13 billion parameters. 
 The primary goal of this model is to improve question-answering and medical dialogue tasks.
 
 ### Training Data
-The training data for this project was sourced from various resources.
-Firstly, we used Anki flashcards to automatically generate questions,
-from the front of the cards and anwers from the back of the card.
-Secondly, we generated medical question-answer pairs from [Wikidoc](https://www.wikidoc.org/index.php/Main_Page).
-We extracted paragraphs with relevant headings, and used Chat-GPT 3.5
-to generate questions from the headings and using the corresponding paragraphs
-as answers. This dataset is still under development and we believe
-that approximately 70% of these question answer pairs are factual correct.
-Thirdly, we used StackExchange to extract question-answer pairs, taking the
-top-rated question from five categories: Academia, Bioinformatics, Biology,
-Fitness, and Health. Additionally, we used a dataset from [ChatDoctor](https://arxiv.org/abs/2303.14070)
