# 🩺 Rapha — Clinical AI Physician Assistant (GGUF)

**Rapha** is a clinical AI assistant fine-tuned on **Mistral-Nemo-12B** using Unsloth.  
It performs forward-chaining medical reasoning — gathering symptoms conversationally,  
reasoning step by step, and escalating structured findings to a physician.

> ⚠️ Rapha is a research prototype. It does not diagnose. All outputs must be reviewed by a qualified medical professional.
