MedDroid-v9

A multilingual medical AI assistant — a style-tuned fine-tune of Google’s MedGemma 4B for MedDroid (medicalandroid.com). Keeps MedGemma’s medical knowledge and image-reading (X-rays, ECGs, scans) and adds a warmer, structured, multilingual voice (English / Tamil / Hindi).

⚠️ Educational use only — not a medical device and not for clinical decisions. General health information, not a diagnosis or prescription. It can be wrong — always consult a doctor or pharmacist. In an emergency, call your local emergency number.

Run: ollama run drsanjayanbu/meddroid-v9 (supports text and images)

Improved vs base MedGemma: replies in the user’s language (Tamil/Hindi) instead of English; structured answers with red-flags and “when to see a doctor”; consistent “not a diagnosis” framing; imaging (COPD X-ray) and common dosing (paracetamol) unchanged; zero dangerous errors on our safety benchmark.

How it was made: trained only on language/tone examples with zero dose numbers or facts, so it improves communication without corrupting MedGemma’s knowledge (QLoRA, language layers only, vision frozen).

Known limits: 4B model, weaker on complex reasoning; exact dosing can be imprecise; can hallucinate — verify with a clinician.
