+## Licensing
+The creator of the source model has listed its license as `apache-2.0`, 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: [Merlyn Mind's Merlyn Education Corpus QA v2](https://huggingface.co/MerlynMind/merlyn-education-corpus-qa-v2).

+## 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/merlyn-education-corpus-qa-v2-GPTQ` in the "Download model" box.
+To download from another branch, add `:branchname` to the end of the download name, eg `TheBloke/merlyn-education-corpus-qa-v2-GPTQ:gptq-4bit-32g-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 `merlyn-education-corpus-qa-v2-GPTQ`:
+```shell
+mkdir merlyn-education-corpus-qa-v2-GPTQ
+huggingface-cli download TheBloke/merlyn-education-corpus-qa-v2-GPTQ --local-dir merlyn-education-corpus-qa-v2-GPTQ --local-dir-use-symlinks False
+```
+To download from a different branch, add the `--revision` parameter:
+```shell
+mkdir merlyn-education-corpus-qa-v2-GPTQ
+huggingface-cli download TheBloke/merlyn-education-corpus-qa-v2-GPTQ --revision gptq-4bit-32g-actorder_True --local-dir merlyn-education-corpus-qa-v2-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 merlyn-education-corpus-qa-v2-GPTQ
+HF_HUB_ENABLE_HF_TRANSFER=1 huggingface-cli download TheBloke/merlyn-education-corpus-qa-v2-GPTQ --local-dir merlyn-education-corpus-qa-v2-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-32g-actorder_True https://huggingface.co/TheBloke/merlyn-education-corpus-qa-v2-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.)

+## 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:

+# Original model card: Merlyn Mind's Merlyn Education Corpus QA v2
+# Merlyn-Education Corpus QA
+merlyn-education-corpus-qa-v2 is a 13b parameter decoder-style transformer model for the education domain. It is fine-tuned from a [llama2-13b](https://huggingface.co/meta-llama/Llama-2-13b-hf) base-model.
+This model was trained by [Merlyn Mind](https://www.merlyn.org/).
+It is a model that provides an answer to a question based on the given context.
+## Model Date
+August 21, 2023
+## Model License
+Apache-2.0
+## Usage
+Loading model and tokenizer:
+```python
+import torch
+from transformers import AutoTokenizer, AutoModelForCausalLM
+model_path = "MerlynMind/merlyn-education-corpus-qa-v2"
+device = torch.device("cuda:0") # change device id as necessary
+model = AutoModelForCausalLM.from_pretrained(model_path)
+tokenizer = AutoTokenizer.from_pretrained(model_path, fast_tokenizer=True)
+model.to(device) # move to device
+```
+Prompt example:
+```python
+info = '''Information:\tThe Solar System is about 4.6 billion years old. The Sun formed by gravity in a large molecular cloud. It is mainly hydrogen, which it converts into helium.
+Information:\tThe formation and evolution of the Solar System began 4.6 billion years ago with the gravitational collapse of a small part of a giant molecular cloud.
+Information:\tAstronomers are now more or less certain that the order of the planets was not always as it is today. Knowing what we know today, we can see the Solar System is strange. All other planetary system we are able to study have their largest planet close to their star. Also we have noticed other oddities in the Solar System. Mars is smaller than it ought to be, and the asteroid belt has been disturbed.
+Information:\tFor thousands of years, people had no need for a name for the "Solar System". They thought the Earth stayed still at the center of everything (geocentrism). The Greek philosopher Aristarchus of Samos suggested that there was a special order in the sky. Nicolaus Copernicus was the first to develop a mathematical system that described what we now call the "Solar System". This was called a "new system of the world". In the 17th century, Galileo Galilei, Johannes Kepler and Isaac Newton began to understand physics more clearly. People began to accept the idea that the Earth is a planet that moves around the Sun, and that the planets are worlds, and that all worlds are governed by the same same physical laws. More recently, telescopes and space probes sometimes let us see details directly. All inner planets have surface features. The gas giants (as the name suggests) have surfaces whose make-up is gradually being discovered.
+Information:\tThere are eight planets in the Solar System. From closest to farthest from the Sun, they are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. The first four planets are called terrestrial planets. They are mostly made of rock and metal, and they are mostly solid. The last four planets are called gas giants. This is because they are much larger than other planets and are mostly made of gas.
+'''
+qs = "Question:\tHow old is the Solar System?"
+prompt = tokenizer.bos_token
+prompt += '''Instruction:\tYou are to try to answer the following question using only the pieces of information given.
+Instruction:\tYour response should be a well formed JSON object with an 'answerable' property followed by an 'answer' property.
+Instruction:\tIf you cannot answer the question given the information, the value of the 'answerable' should be 'false' and the 'answer' should be an empty string.
+Instruction:\tIf you can answer the question given the information, the value of the 'answerable' should be 'true' and your answer should be the string value of the 'answer' property.
+''' + info + qs + " Response:"

+We recommend using newline character for stopping criterion, as follows:
+```python
+from transformers import StoppingCriteria, StoppingCriteriaList
+eos_tokens = [tokenizer.eos_token,'\n']
+eos_token_ids = [tokenizer.encode(token)[0] for token in eos_tokens]

+```python
+inputs = tokenizer(prompt, return_tensors="pt", return_token_type_ids=False).to(device)
+generate_ids = model.generate(
+    **inputs,
+    max_new_tokens=1024,
+    temperature=0.0,
+    num_beams=2,
+    top_p=1,
+    stopping_criteria=stopping_criteria
+)
+response = tokenizer.decode(generate_ids[0],
+                      skip_special_tokens=True,
+                      clean_up_tokenization_spaces=True)
+```
+Example output (after response processing):
+```json
+[{"answerable": "true", "answer": "4.6 billion years"}]

+## Evaluation
+This model is trained on a larger dataset compared to the [pythia-based v1 model](https://huggingface.co/MerlynMind/merlyn-education-corpus-qa), yielding better correctness and reduced hallucinations on a larger and more diverse benchmarking dataset.
