Readme
Based on Medichat-Llama3-8B. It is quantized to q4_K_M for a balance between memory usage and output quality.
Medichat-Llama3-8B
Built upon the powerful LLaMa-3 architecture and fine-tuned on an extensive dataset of health information, this model leverages its vast medical knowledge to offer clear, comprehensive answers.
The following YAML configuration was used to produce this model:

Usage:
from transformers import AutoTokenizer, AutoModelForCausalLM
# Load tokenizer and model
tokenizer = AutoTokenizer.from_pretrained("sethuiyer/Medichat-Llama3-8B")
model = AutoModelForCausalLM.from_pretrained("sethuiyer/Medichat-Llama3-8B").to("cuda")
# Function to format and generate response with prompt engineering using a chat template
def askme(question):
sys_message = '''
You are an AI Medical Assistant trained on a vast dataset of health information. Please be thorough and
provide an informative answer. If you don't know the answer to a specific medical inquiry, advise seeking professional help.
'''
# Create messages structured for the chat template
messages = [{"role": "system", "content": sys_message}, {"role": "user", "content": question}]
# Applying chat template
prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(prompt, return_tensors="pt").to("cuda")
outputs = model.generate(**inputs, max_new_tokens=512, use_cache=True) # Adjust max_new_tokens for longer responses
# Extract and return the generated text
answer = tokenizer.batch_decode(outputs)[0].strip()
return answer
## Example usage
question = '''
Symptoms:
Dizziness, headache and nausea.
What is the differnetial diagnosis?
'''
print(askme(question))
