🩺 ZeroTime-Bot: Medical Triage Alignment

Problem: Standard AI models often "over-triage" (e.g., calling a stubbed toe an emergency) due to safety-bias in training data. Solution: Used GRPO (Reinforcement Learning) to align a Llama-3.1 8B model to recognize clinical nuances between Level 1 (Emergency) and Level 3 (Non-Urgent).

🚀 Quick Start (Local Run)

1. Install Ollama.
2. Download the medical_triage.gguf from my [Hugging Face Link].
3. Run: ollama create medicalbot -f Modelfile
4. Run: ollama run medicalbot

📊 Results: Before vs. After

Scenario	Base Llama-3.1	My Aligned Model	Result
Stubbed Toe	Level 1 (Emergency)	Level 3 (Non-Urgent)	✅ Fixed Bias
Chest Pain	Level 1 (Emergency)	Level 1 (Emergency)	✅ Kept Safety

🛠️ Technical Approach

Instead of standard fine-tuning (SFT), we utilized Group Relative Policy Optimization (GRPO). We created a reward function that penalized the model for assigning "Emergency" status to cases with stable clinical indicators, forcing it to develop deeper medical reasoning.
