OpenAI’s Head of Health AI on Whether You Should Trust ChatGPT

Video summary

OpenAI’s Karan Singhal says ChatGPT can make health guidance more accessible, while doctors remain essential to care.

OpenAI health lead Karan Singhal says more than 300 million people use ChatGPT weekly for health questions, often between appointments when access to doctors is slow and visits are brief. He describes how AI helped Nathan Labenz’s family navigate his son’s symptoms before an aggressive leukemia diagnosis, while stressing that AI should complement—not replace—clinicians. OpenAI trains healthcare expertise into its general models and evaluates them with hundreds of physicians and mental-health experts, prioritizing safety when users want reassurance but need urgent care. Singhal says clinical guidance can take five to 17 years to reach everyday practice, and AI could help narrow that delay. He points to Epic integrations, AdventHealth’s reported 80% reduction in administrative workflow, and cheaper models as steps toward wider access. Longer term, proactive assistants may flag health risks and help navigate care; AI-guided research could also accelerate new, more personalized treatments.
