OpenAI’s Head of Health AI on Whether You Should Trust ChatGPT
The a16z Show

Summary
OpenAI is treating health as a major application of its general-purpose models, with the goal of making trustworthy medical intelligence abundant, cheap, and available to both patients and clinicians. Karan Singhal argues that the company is not trying to replace doctors; instead, it wants AI to act as a proactive assistant, a safety net, and a way to reduce the friction of getting care in a fragmented system.
A central theme is trust. OpenAI says it trains healthcare behavior directly into its frontier models, works with hundreds of physicians and mental health experts worldwide, and evaluates for difficult tradeoffs like reassurance versus medical correctness. Karan Singhal says the company also designs for different user types, from lay users to clinicians, so the model can adapt its language, uncertainty, and recommendations appropriately.
The conversation also focuses on workflow. OpenAI sees big value in helping with scheduling, records, follow-up, and care navigation, including integrations with Epic and clinician copilots. Karan Singhal expects costs to keep falling sharply, which could expand access and reduce administrative waste, while AI helps compress the lag between medical evidence and everyday practice.
Key takeaways
- Karan Singhal says OpenAI’s goal is to raise the floor and ceiling of health by making “trustworthy, abundant, reliable health intelligence” nearly free.
- OpenAI trains healthcare knowledge into its frontier models rather than a separate specialist model, because Karan Singhal says the frontier improves too quickly for a standalone model to keep up.
- Karan Singhal says OpenAI uses a global physician network and formal evaluations to handle disagreement, uncertainty, and the difference between what users want to hear and what is clinically correct.
- He expects AI to become a safety net for patients and clinicians, including checks for medication interactions, abnormal labs, and other chronic-care flags.
- Karan Singhal says the biggest near-term opportunity is reducing fragmentation in healthcare through tools like Epic integration, clinician copilots, and personal agents that handle logistics and navigation.

How the episode opens
5.3 plus trillion we spend on healthcare. If it were its own country, it'd be the third largest GDP. And yet we have a ton of scarcity.
Open's mission is to ensure AGI benefits all of humanity and give people access to trustworthy, abundant, reliable health intelligence. One of the stories that I was most touched by was the story of Nathan Levent. He basically had this kind of long saga with his son where at some point he was suffering a lot of fatigue and irritableness and AI helped them navigate the process and it turns out he was diagnosed with an aggressive form of leukemia.
some of the work that you've done around mental health. There's a lot of complexity. How do you help guide a user on that given that could mean so many things?
We've just been working with a bunch of licensed mental health experts across the world to think about the right ways to define model behavior and a bunch of tricky scenarios and ensure that we can get to a level of consensus where we can actually measure performance.
Let's talk about trust. A person can be speaking to an LLM really hoping to hear that everything is okay, but from a medical perspective, they need to hear perhaps something very different. How do you teach an AI to recognize the difference? Um,
Hey everyone. Welcome back to the podcast. I'm Jay Rugani, a partner at A16Z, leading investments in healthcare and biotechnology companies. I'm joined by Karin Singal of OpenAI. He leads health AI research at OpenAI and we've got a lot to talk about. Thanks for being here.
Thanks for having me. — I want to start with the big question. Uh, there was a report earlier this year.
