AMIE matched doctors in video consults — and patients liked it

Google just ran the first randomized study of an AI doing real-time video consultations — and its medical system held its own against human doctors. AMIE, built on Gemini plus Project Astra, saw 15 patient actors across 100 clinical scenarios, going head-to-head with 30 primary care physicians on video. A blind panel of 20 experienced PCPs graded every consult.

The verdict: AMIE rated on par or better than the physicians on history-taking, diagnosis, management, and — the surprising part — physical observation and examination, where it guided patients through virtual exams using the camera feed. Patient actors preferred how AMIE assessed and explained their conditions. Doctors still won on rapport and partnership.

The engineering trick is architectural: a fast talker agent keeps the conversation flowing at conversational latency while slower perception and diagnostic-reasoning agents grind away in the background. No awkward pauses while the model thinks. Google has since run a feasibility study with Beth Israel Deaconess Medical Center, and a nationwide randomized trial with Included Health is now testing this in actual virtual care — the step that moves it out of the lab.

Why it matters: telehealth is the one place AI can practice medicine end-to-end today, and the human-parity bar just got cleared in a controlled trial.
