Medical-Llama3-8B-GGUF
This is a fine-tuned version of the Llama3 8B model, specifically designed to answer medical questions.
The model was trained on the AI Medical Chatbot dataset, which can be found at ruslanmv/ai-medical-chatbot. This fine-tuned model leverages the GGUF (General-Purpose Gradient-based Quantization with Uniform Forwarding) technique for efficient inference with 4-bit quantization.

Example of use
Here's an example of how to use the Medical-Llama3-8B-GGUF 4bit model to generate an answer to a medical question:
from llama_cpp import Llama
import json
B_INST, E_INST = "<s>[INST]", "[/INST]"
B_SYS, E_SYS = "<<SYS>>\n", "\n<</SYS>>\n\n"
DEFAULT_SYSTEM_PROMPT = """\
You are an AI Medical Chatbot Assistant, I'm equipped with a wealth of medical knowledge derived from extensive datasets. I aim to provide comprehensive and informative responses to your inquiries. However, please note that while I strive for accuracy, my responses should not replace professional medical advice and short answers.
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."""
SYSTEM_PROMPT = B_SYS + DEFAULT_SYSTEM_PROMPT + E_SYS
def create_prompt(user_query):
instruction = f"User asks: {user_query}\n"
prompt = B_INST + SYSTEM_PROMPT + instruction + E_INST
return prompt.strip()
user_query = "I'm a 35-year-old male experiencing symptoms like fatigue, increased sensitivity to cold, and dry, itchy skin. Could these be indicative of hypothyroidism?"
prompt = create_prompt(user_query)
print(prompt)
llm = Llama(model_path=MODEL_PATH, n_gpu_layers=-1)
result = llm(
prompt=prompt,
max_tokens=100,
echo=False
)
print(result['choices'][0]['text'])
The output exmample
Hi, thank you for your query.
Hypothyroidism is characterized by fatigue, sensitivity to cold, weight gain, depression, hair loss and mental dullness. I would suggest that you get a complete blood count with thyroid profile including TSH (thyroid stimulating hormone), free thyroxine level, and anti-thyroglobulin antibodies. These tests will help in establishing the diagnosis of hypothyroidism.
If there is no family history of autoimmune disorders, then it might be due
