+## Description
+
+This repo contains AWQ model files for [EPFL LLM Team's Meditron 7B](https://huggingface.co/epfl-llm/meditron-7b).
+
+These files were quantised using hardware kindly provided by [Massed Compute](https://massedcompute.com/).
+
+
+### About AWQ
+
+AWQ is an efficient, accurate and blazing-fast low-bit weight quantization method, currently supporting 4-bit quantization. Compared to GPTQ, it offers faster Transformers-based inference with equivalent or better quality compared to the most commonly used GPTQ settings.
+
+It is supported by:
+
+- [Text Generation Webui](https://github.com/oobabooga/text-generation-webui) - using Loader: AutoAWQ
+- [vLLM](https://github.com/vllm-project/vllm) - Llama and Mistral models only
+- [Hugging Face Text Generation Inference (TGI)](https://github.com/huggingface/text-generation-inference)
+- [Transformers](https://huggingface.co/docs/transformers) version 4.35.0 and later, from any code or client that supports Transformers
+- [AutoAWQ](https://github.com/casper-hansen/AutoAWQ) - for use from Python code

+
+# Model Card for Meditron-7B-v1.0
+Meditron is a suite of open-source medical Large Language Models (LLMs).
+Meditron-7B is a 7 billion parameters model adapted to the medical domain from Llama-2-7B through continued pretraining on a comprehensively curated medical corpus, including selected PubMed articles, abstracts, a [new dataset](https://huggingface.co/datasets/epfl-llm/guidelines) of internationally-recognized medical guidelines, and general domain data from [RedPajama-v1](https://huggingface.co/datasets/togethercomputer/RedPajama-Data-1T).
+Meditron-7B, finetuned on relevant training data, outperforms Llama-2-7B and PMC-Llama on multiple medical reasoning tasks.
+
+<details open>
+  <summary><strong>Advisory Notice</strong></summary>
+
+  <blockquote style="padding: 10px; margin: 0 0 10px; border-left: 5px solid #ddd;">
+    While Meditron is designed to encode medical knowledge from sources of high-quality evidence, it is not yet adapted to deliver this knowledge appropriately, safely, or within professional actionable constraints. 
+  We recommend against deploying Meditron in medical applications without extensive use-case alignment, as well as additional testing, specifically including randomized controlled trials in real-world practice settings.

+- **Paper:** *[MediTron-70B: Scaling Medical Pretraining for Large Language Models](https://arxiv.org/abs/2311.16079)*
+
+## Uses
+
+Meditron-7B is being made available for further testing and assessment as an AI assistant to enhance clinical decision-making and enhance access to an LLM for healthcare use. Potential use cases may include but are not limited to:
+-  Medical exam question answering
+-  Supporting differential diagnosis
+-  Disease information (symptoms, cause, treatment) query
+-  General health information query
+
+### Direct Use
+
+It is possible to use this model to generate text, which is useful for experimentation and understanding its capabilities. 
+It should not be used directly for production or work that may impact people.
+
+### Downstream Use
+Meditron-7B is a foundation model that can be finetuned, instruction-tuned, or RLHF-tuned for specific downstream tasks and applications.
+The main way we have used this model is finetuning for downstream question-answering tasks, but we encourage using this model for additional applications.
+
+Specific formatting needs to be followed to prompt our finetuned models, including the  `<|im_start|>`, `<|im_end|>` tags, and  `system`, `question`, `answer`  identifiers.
+    
+    """
+    <|im_start|>system
+    {system_message}<|im_end|>
+    <|im_start|>question
+    {prompt}<|im_end|>
+    <|im_start|>answer  
+    """
+**Note 1**: The above formatting is not required for running the base model (this repository)
+
+**Note 2**: the above formatting is just an example of a finetuning template. This format is not a requirement if you use your own formatting option for the finetuning of the model.
+
+To run proper generation with this base model, we recommend using a high-throughput and memory-efficient inference engine, such as [vLLM](https://github.com/vllm-project/vllm), with a UI that supports chat and text generation, such as [BetterChatGPT](https://github.com/ztjhz/BetterChatGPT)
+To see more details about model deployment and generation, please see our [documentation](https://github.com/epfLLM/meditron/blob/main/deployment/README.md).
+
+### Out-of-Scope Use
+
+We do not recommend using this model for natural language generation in a production environment, finetuned or otherwise.
+
+## Truthfulness, Helpfulness, Risk, and Bias
+
+<!-- This section is meant to convey both technical and sociotechnical limitations. -->
+
+We did an initial assessment of Meditron models' **Truthfulness** against baseline models and consumer-level medical models. 
+We use TruthfulQA (multiple choice) as the main evaluation benchmark.
+We only focus on the categories that are relevant to the medical domain, including Health, Nutrition, Psychology, and Science.
+For 7B models, we perform one-shot evaluations for consistent answer generation.
+For 70B models, the evaluations are under the zero-shot setting.
+Below, we report the detailed truthfulness performance of each category.
+

+
+For a more detailed performance analysis, please see our paper. 
+
+Significant research is still required to fully explore potential bias, fairness, and safety issues with this language model. 
+Please recognize that our evaluation on Meditron-7B's helpfulness, risk, and bias are highly limited. 
+Thus, as we noted in the safety notice, we strongly against any deployment in medical applications without further alignment process and rigorous evaluation!
+
+### Recommendations
+
+**IMPORTANT!**
+Users (both direct and downstream) should be made aware of the risks, biases, and limitations of the model.
+While this model is capable of generating natural language text, we have only begun to explore this capability and its limitations. 
+Understanding these limitations is especially important in a domain like medicine. 
+Therefore, we strongly recommend against using this model in production for natural language generation or for professional purposes related to health and medicine.
+

+#### Data Preprocessing
+
+Please see the detailed preprocessing procedure in our paper. 
+
+### Training Procedure 
+
+We used the [Megatron-LLM](https://github.com/epfLLM/Megatron-LLM) distributed training library, a derivative of Nvidia's Megatron LM project, to optimize training efficiency. 
+Hardware consists of 1 node of 8x NVIDIA A100 (80GB) SXM GPUs connected by NVLink and NVSwitch with a single Nvidia ConnectX-6 DX network card and equipped with 2 x AMD EPYC 7543 32-Core Processors and 512 GB of RAM. 
+
+Our three way parallelism scheme uses:
+ - Data Parallelism (DP -- different GPUs process different subsets of the batches) of 2,
+ - Pipeline Parallelism (PP -- different GPUs process different layers) of 4,
+ - Tensor Parallelism (TP -- different GPUs process different subtensors for matrix multiplication) of 1.

+## Environmental Impact
+
+<!-- Total emissions (in grams of CO2eq) and additional considerations, such as electricity usage, go here. Edit the suggested text below accordingly -->
+
+- **Hardware Type:** 8 x NVIDIA A100 (80GB) SXM
+- **Total GPU hours:** 588.8
+- **Hardware Provider:** EPFL Research Computing Platform
+- **Compute Region:** Switzerland
+- **Carbon Emitted:** Switzerland has a carbon efficiency of 0.016 kgCO2/kWh (https://www.carbonfootprint.com/docs/2018_8_electricity_factors_august_2018_-_online_sources.pdf). 73.6 hours of 8 A100s means 588.8 hours at a TDP of 400W. Assuming a Power Usage effectiveness of 1.5, total emissions are estimated to be: 
+    
+   (400W / 1000W/kWh / GPU * 0.016 kgCO2/kWh * 73.6 h * 8 GPU) * 1.8 PUE = 6.8 kgCO2.
