Doctronic Cuts Emergency Screening Costs 750x Using Small Models

dragon_khoi · x · 2026-08-06

Medical AI app Doctronic shared its engineering practice for checking patient emergencies (e.g., heart attacks, strokes).

Architecture: The system uses independent AI models called Guardians to monitor dangers, operating separately from the conversational AI.
Optimization: Initial checks calling multiple LLMs were slow and expensive. The team trained small, fast models using their own data with LLMs as teachers.
Results: Most cases now clear in under 1 millisecond, costing 750x less and saving over 1 second per message. The team plans to open-source these models.
