# SandLogic Technologies - Quantized Llama3-Med42-8B Models

## Model Description

We have quantized the Llama3-Med42-8B model into two variants:

1. Q5_KM
2. Q4_KM

These quantized models offer improved efficiency while maintaining performance.

Discover our full range of quantized language models by visiting our [SandLogic Lexicon](https://github.com/sandlogic/SandLogic-Lexicon) GitHub.

## Original Model Information

- **Name**: [Llama3-Med42-8B](https://huggingface.co/m42-health/Llama3-Med42-8B)
- **Developer**: M42 Health AI Team
- **Base Model**: [Llama3-8B-Instruct](https://huggingface.co/meta-llama/Meta-Llama-3-8B-Instruct)
- **Model Type**: Clinical large language model (LLM)
- **Parameters**: 8 billion
- **Context Length**: 8k tokens
- **Input**: Text only
- **Output**: Text only
- **License**: Llama 3 Community License Agreement

## Model Capabilities

Llama3-Med42-8B is designed for medical and healthcare-related tasks, including:

- Medical question answering
- Patient record summarization
- Aiding medical diagnosis
- General health Q&A

## Training Data

The model was instruction-tuned using a dataset of approximately 1 billion tokens compiled from various open-access and high-quality sources, including:

- Medical flashcards
- Exam questions
- Open-domain dialogues

## Important Limitations and Safe Use

**DISCLAIMER: This model is not yet ready for clinical use without further testing and validation. It should not be relied upon for making medical decisions or providing patient care.**

- Potential for generating incorrect or harmful information
- Risk of perpetuating biases in training data
- Requires extensive human evaluation to ensure safety

## Use Cases

While not ready for real clinical use, potential applications include:

1. **Medical Education**: Assist in studying and understanding medical concepts
2. **Research Support**: Aid in literature review and hypothesis generation
3. **Health Information**: Provide general health information (with appropriate disclaimers)
4. **Clinical Decision Support**: (Future potential) Enhance clinical decision-making processes

## Model Variants

We offer two quantized versions of the Llama3-Med42-8B model:

1. **Q5_KM**: 5-bit quantization using the KM method
2. **Q4_KM**: 4-bit quantization using the KM method

These quantized models aim to reduce model size and improve inference speed while maintaining performance as close to the original model as possible.

## Usage

```bash
pip install llama-cpp-python 
```
Please refer to the llama-cpp-python [documentation](https://llama-cpp-python.readthedocs.io/en/latest/) to install with GPU support.

### Basic Text Completion
Here's an example demonstrating how to use the high-level API for basic text completion:

```bash
from llama_cpp import Llama

llm = Llama(
    model_path="./models/7B/Llama3-Med42-8B.gguf",
    verbose=False,
    # n_gpu_layers=-1, # Uncomment to use GPU acceleration
    # n_ctx=2048, # Uncomment to increase the context window
)

output = llm.create_chat_completion(
    messages =[
    {
        "role": "system",
        "content": (
            "You are a helpful, respectful and honest medical assistant. You are a second version of Med42 developed by the AI team at M42, UAE. "
            "Always answer as helpfully as possible, while being safe. "
            "Your answers should not include any harmful, unethical, racist, sexist, toxic, dangerous, or illegal content. "
            "Please ensure that your responses are socially unbiased and positive in nature. If a question does not make any sense, or is not factually coherent, explain why instead of answering something not correct. "
            "If you don’t know the answer to a question, please don’t share false information."
        ),
    },
    {"role": "user", "content": "What are the symptoms of diabetes?"},
]
)

print(output["choices"][0]['message']['content'])
```

## Download
You can download `Llama` models in `gguf` format directly from Hugging Face using the `from_pretrained` method. This feature requires the `huggingface-hub` package.

To install it, run: `pip install huggingface-hub`

```bash
from llama_cpp import Llama

llm = Llama.from_pretrained(
    repo_id="SandLogicTechnologies/Llama3-Med42-8B-GGUF",
    filename="*Llama3-Med42-8B-Q5_K_M.gguf",
    verbose=False
)
```
By default, from_pretrained will download the model to the Hugging Face cache directory. You can manage installed model files using the huggingface-cli tool.


## Ethical Considerations

Users must be aware of the model's limitations and potential biases. It should not be used for direct medical advice or decision-making without proper validation and human oversight.
