Model: thebnbrkr/hippocratically_llama3.2
Base: meta-llama/Llama-3.2-3B-Instruct
Fine-tuning: LoRA (via PEFT + TRL’s SFTTrainer)
Dataset: ruslanmv/ai-medical-chatbot (public medical Q&A)

Model Description

hippocratically_llama3.2 is a LoRA-finetuned version of Meta’s LLaMA 3.2B-Instruct model, adapted for clinical dialogue and general medical question-answering. It uses instruction-tuning and parameter-efficient fine-tuning (PEFT) methods to create a compact and responsive healthcare assistant for research and educational use.

Intended Use

Medical Q&A chatbot simulations
Research on LoRA-based instruction tuning
Prompt evaluation in clinical contexts
LLM alignment/hallucination analysis

Limitations

Not suitable for clinical deployment
May hallucinate outdated or unsafe information
Doesn't prioritize emergencies unless prompted
Lacks real-time patient data or diagnostic context

Example Prompt:

prompt: | How can someone determine their metabolic rate?

Example response:

Metabolic rate can be determined in several ways, depending on the context and level of precision required.

Basal Metabolic Rate (BMR): This is the number of calories your body needs at rest. A commonly used formula to estimate BMR for women is:

BMR = 655 + (4.35 × weight in lbs) + (4.7 × height in inches) – (4.7 × age in years)

For men:

BMR = 66 + (6.23 × weight in lbs) + (12.7 × height in inches) – (6.8 × age in years)
Harris-Benedict Equation: This builds on BMR to estimate Total Daily Energy Expenditure (TDEE) by multiplying the BMR by an activity factor (e.g., 1.2 for sedentary, 1.55 for moderate activity).
Clinical Methods: More accurate tests, like indirect calorimetry, measure oxygen consumption and carbon dioxide production to calculate actual energy expenditure.
Wearables and Apps: Fitness trackers and smart devices offer real-time estimates, though they are less precise.

Always consult a healthcare provider for personalized metabolic assessments or weight management planning.
