Forty million people use ChatGPT for health-related questions every day, making it one of the most widely used tools for health information in the world. So what is their team doing to maximize impact and minimize harm? For one, they've brought in hundreds of physicians globally to continuously review outputs and shape how the models respond across different scenarios, literacy levels, and edge cases. Second, they've hired my Rock Health co-founder, Nate Gross, MD, as their VP of Health.

In this full-circle episode, I sit down with Nate, who also co-founded Doximity (DOCS) and knows a thing or two about building in digital health. We discuss the astonishing speed of AI progress, how models are trained for safety and accuracy, and what this technological evolution means for every part of the healthcare system.

Key topics:

  • How ChatGPT is becoming a 24/7 front door for health questions, and whether it is replacing Dr. Google or starting to compete with the healthcare system itself
  • How OpenAI is trying to reduce hallucinations, avoid sycophantic behavior, and build guardrails for sensitive use cases like mental health
  • OpenAI’s goals to “raise the floor, sweep the floor, and raise the ceiling” with new product launches like ChatGPT for Clinicians and GPT-Rosalind
  • How Nate thinks about the AI race and what winning in healthcare actually requires
  • Where startups should focus their efforts now that specialized products are launching for clinicians and life sciences
  • The single hardest problem in healthcare that AI, according to Nate, probably won't fix anytime soon
