a16z · x · 2026-10-21
a16z partner Jay Rughani sits down with OpenAI's health AI lead Karan Singhal on why personal healthcare agents are finally ripe.
- Rughani argues fragmented, legacy-software-laden health systems are exactly where agents navigating on patients' behalf can have impact; Singhal calls healthcare "absolutely ripe for agents and computer use."
- a16z cites that over 300 million people use ChatGPT for health and wellness questions each week — and Singhal thinks that's only the beginning.
- Topics include how OpenAI builds health intelligence, advantages of general models for health, the 5–17 year lag of medical consensus, AI for mental health, and driving down the cost of care.
