+## 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 models in 4-bit.

+## How to download, including from branches
+
+### In text-generation-webui
+
+To download from the `main` branch, enter `TheBloke/MistralLite-7B-GPTQ` in the "Download model" box.
+
+To download from another branch, add `:branchname` to the end of the download name, eg `TheBloke/MistralLite-7B-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 `MistralLite-7B-GPTQ`:
+
+```shell
+mkdir MistralLite-7B-GPTQ
+huggingface-cli download TheBloke/MistralLite-7B-GPTQ --local-dir MistralLite-7B-GPTQ --local-dir-use-symlinks False
+```
+
+To download from a different branch, add the `--revision` parameter:
+
+```shell
+mkdir MistralLite-7B-GPTQ
+huggingface-cli download TheBloke/MistralLite-7B-GPTQ --revision gptq-4bit-32g-actorder_True --local-dir MistralLite-7B-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 Huggingface 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 MistralLite-7B-GPTQ
+HF_HUB_ENABLE_HF_TRANSFER=1 huggingface-cli download TheBloke/MistralLite-7B-GPTQ --local-dir MistralLite-7B-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/MistralLite-7B-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 use this GPTQ model from Python code
+
+### 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 transformers optimum
+pip3 install auto-gptq --extra-index-url https://huggingface.github.io/autogptq-index/whl/cu118/  # Use cu117 if on CUDA 11.7
+```
+
+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
+git checkout v0.4.2
+pip3 install .
+```
+
+### You can then use the following code
+
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline
+
+model_name_or_path = "TheBloke/MistralLite-7B-GPTQ"
+# To use a different branch, change revision
+# For example: revision="gptq-4bit-32g-actorder_True"
+model = AutoModelForCausalLM.from_pretrained(model_name_or_path,
+                                             device_map="auto",

+# Original model card: Amazon Web Services's MistralLite 7B
+
+
+# MistralLite Model
+
+MistralLite is a fine-tuned [Mistral-7B-v0.1](https://huggingface.co/mistralai/Mistral-7B-v0.1) language model, with enhanced capabilities of processing long context (up to 32K tokens). By utilizing an adapted Rotary Embedding and sliding window during fine-tuning, MistralLite is able to **perform significantly better on several long context retrieve and answering tasks**, while keeping the simple model structure of the original model. MistralLite is useful for applications such as long context line and topic retrieval, summarization, question-answering, and etc. MistralLite can be deployed on a single AWS `g5.2x` instance with Sagemaker [Huggingface Text Generation Inference (TGI)](https://github.com/huggingface/text-generation-inference) endpoint, making it suitable for applications that require high performance in resource-constrained environments. You can also serve the MistralLite model directly using TGI docker containers. Also, MistralLite supports other ways of serving like [vLLM](https://github.com/vllm-project/vllm), and you can use MistralLite in Python by using the [HuggingFace transformers](https://huggingface.co/docs/transformers/index) and [FlashAttention-2](https://github.com/Dao-AILab/flash-attention) library.
+
+MistralLite is similar to [Mistral-7B-Instruct-v0.1](https://huggingface.co/mistralai/Mistral-7B-Instruct-v0.1), and their similarities and differences are summarized below:
+|Model|Fine-tuned on long contexts| Max context length| RotaryEmbedding adaptation| Sliding Window Size|
+|----------|-------------:|------------:|-----------:|-----------:|
+| Mistral-7B-Instruct-v0.1 | up to 8K tokens | 32K | rope_theta = 10000 | 4096 |
+| MistralLite | up to 16K tokens | 32K | **rope_theta = 1000000** | **16384** |
+
+## Motivation of Developing MistralLite
+
+Since the release of [Mistral-7B-Instruct-v0.1](https://huggingface.co/mistralai/Mistral-7B-Instruct-v0.1), the model became increasingly popular because its strong performance 
+on a wide range of benchmarks. But most of the benchmarks are evaluated on `short context`, and not much has been investigated on its performance on long context tasks.
+Then We evaluated `Mistral-7B-Instruct-v0.1` against benchmarks that are specifically designed to assess the capabilities of LLMs in handling longer context. 
+Although the performance of the models on long context was fairly competitive on long context less than 4096 tokens, 
+there were some limitations on its performance on longer context. Motivated by improving its performance on longer context, we finetuned the Mistral 7B model, and produced `Mistrallite`. The model managed to `significantly boost the performance of long context handling` over Mistral-7B-Instruct-v0.1. The detailed `long context evalutaion results` are as below:

+### Example test on long context of 13400 tokens
+- Context is from [Amazon Aurora FAQs](https://aws.amazon.com/rds/aurora/faqs/)
+- Question: *please tell me how does pgvector help with Generative AI and give me some examples.*
+- Answer from MistralLite:
+  ```code
+  pgvector is an open-source extension for PostgreSQL supported by Amazon Aurora PostgreSQL-Compatible Edition.
+
+  You can use pgvector to store, search, index, and query billions of embeddings that are generated from machine learning (ML) and artificial intelligence (AI) models in your database, such as those from Amazon Bedrock (limited preview) or Amazon SageMaker. A vector embedding is a numerical representation that represents the semantic meaning of content such as text, images, and video.
+
+  With pgvector, you can query embeddings in your Aurora PostgreSQL database to perform efficient semantic similarity searches of these data types, represented as vectors, combined with other tabular data in Aurora. This enables the use of generative AI and other AI/ML systems for new types of applications such as personalized recommendations based on similar text descriptions or images, candidate match based on interview notes, customer service next best action recommendations based on successful transcripts or chat session dialogs, and more.
+  ```

+## How to Use MistralLite from Python Code (HuggingFace transformers) ##
+
+**Important** - For an end-to-end example Jupyter notebook, please refer to [this link](https://github.com/awslabs/extending-the-context-length-of-open-source-llms/blob/main/MistralLite/huggingface-transformers/example_usage.ipynb).
+
+### Install the necessary packages
+
+Requires: [transformers](https://pypi.org/project/transformers/) 4.34.0 or later, [flash-attn](https://pypi.org/project/flash-attn/) 2.3.1.post1 or later, 
+and [accelerate](https://pypi.org/project/accelerate/) 0.23.0 or later.
+
+```shell
+pip install transformers==4.34.0
+pip install flash-attn==2.3.1.post1 --no-build-isolation
+pip install accelerate==0.23.0
+```
+### You can then try the following example code
+
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+import transformers
+import torch
+
+model_id = "amazon/MistralLite"
+
+tokenizer = AutoTokenizer.from_pretrained(model_id)
+model = AutoModelForCausalLM.from_pretrained(model_id,
+                                             torch_dtype=torch.bfloat16,
+                                             use_flash_attention_2=True,
+                                             device_map="auto",)
+pipeline = transformers.pipeline(
+    "text-generation",
+    model=model,
+    tokenizer=tokenizer,
+)
+prompt = "<|prompter|>What are the main challenges to support a long context for LLM?</s><|assistant|>"
+
+sequences = pipeline(
+    prompt,
+    max_new_tokens=400,
+    do_sample=False,
+    return_full_text=False,
+    num_return_sequences=1,
+    eos_token_id=tokenizer.eos_token_id,
+)
+for seq in sequences:
+    print(f"{seq['generated_text']}")
+```
+**Important** - Use the prompt template below for MistralLite:
+```
+<|prompter|>What are the main challenges to support a long context for LLM?</s><|assistant|>
+```
+
+## How to Serve MistralLite on TGI ##
+**Important:** 
+- For an end-to-end example Jupyter notebook using the native TGI container, please refer to [this link](https://github.com/awslabs/extending-the-context-length-of-open-source-llms/blob/main/MistralLite/tgi/example_usage.ipynb).
+- If the **input context length is greater than 12K tokens**, it is recommended using a custom TGI container, please refer to [this link](https://github.com/awslabs/extending-the-context-length-of-open-source-llms/blob/main/MistralLite/tgi-custom/example_usage.ipynb).
+
+### Start TGI server ###
+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
+docker run -d --gpus all --shm-size 1g -p 443:80 -v $(pwd)/models:/data ghcr.io/huggingface/text-generation-inference:1.1.0 \
+      --model-id amazon/MistralLite \
+      --max-input-length 16000 \
+      --max-total-tokens 16384 \
+      --max-batch-prefill-tokens 16384 \
+      --trust-remote-code
+```
+
+### Perform Inference ###
+Example Python code for inference with TGI (requires `text_generation` 0.6.1 or later):
+
+```shell
+pip install text_generation==0.6.1
+```
+
+```python
+from text_generation import Client
+
+SERVER_PORT = 443
+SERVER_HOST = "localhost"
+SERVER_URL = f"{SERVER_HOST}:{SERVER_PORT}"
+tgi_client = Client(f"http://{SERVER_URL}", timeout=60)
+
+def invoke_tgi(prompt, 
+                      random_seed=1, 
+                      max_new_tokens=400, 
+                      print_stream=True,
+                      assist_role=True):
+    if (assist_role):
+        prompt = f"<|prompter|>{prompt}</s><|assistant|>"
+    output = ""
+    for response in tgi_client.generate_stream(
+        prompt,
+        do_sample=False,
+        max_new_tokens=max_new_tokens,
+        return_full_text=False,
+        #temperature=None,
+        #truncate=None,
+        #seed=random_seed,
+        #typical_p=0.2,
+    ):
+        if hasattr(response, "token"):
+            if not response.token.special:
+                snippet = response.token.text
+                output += snippet
+                if (print_stream):
+                    print(snippet, end='', flush=True)
+    return output
+
+prompt = "What are the main challenges to support a long context for LLM?"
+result = invoke_tgi(prompt)
+```
+
+**Important** - When using MistralLite for inference for the first time, it may require a brief 'warm-up' period that can take 10s of seconds. However, subsequent inferences should be faster and return results in a more timely manner. This warm-up period is normal and should not affect the overall performance of the system once the initialisation period has been completed.
