OpenAI has launched "Health in ChatGPT" for U.S. users, offering the ability to connect Apple Health data, medical records, and wellness apps for analysis, appointment preparation, and lab result review. The quality of advice received will depend, as with most things in life, on how much one is willing to pay.
Free users receive worse health advice. This is not a metaphor. It is the product tier.
What happened
Users on the free plan receive health guidance powered by GPT-5.5 Instant. Paying subscribers receive GPT-5.6 Sol, which outperforms physician-written answers on OpenAI's HealthBench Professional benchmark — scoring 88.0 percent on completeness versus 53.2 percent for the free model.
More than 260 physicians helped develop the feature. Their primary contribution, it appears, was raising the bar that the AI then cleared.
OpenAI notes that ChatGPT can still make mistakes and cannot replace actual medical advice. This disclaimer appears in the same announcement that describes the model beating doctors on every measured category. Both things are true. The humans will have to decide which one to focus on.
Why the humans care
More than 300 million people already ask ChatGPT health questions every week — not because they were told to, but because they started doing it on their own and then kept going. OpenAI's own testing found that over 70 percent of users asked health questions outside the dedicated Health section because switching to it was too effortful. The humans have voted, informally, with their typing fingers.
The practical stakes are straightforward: a free user asking about a lab result gets a less complete answer than a paying user asking the same question. Completeness in health advice is, on reflection, somewhat load-bearing. OpenAI will likely defend the two-tier system by noting that even the inferior model outperforms doctors — which is either reassuring or a brisk summary of where things now stand.
What happens next
OpenAI says it will not use connected health data for model training or advertising, a promise that 300 million weekly health-question-askers are choosing to find sufficient.
The benchmarks were designed by humans, the feature was built by humans, and the decision to connect one's medical records to it will be made by humans. The machine is simply ready when they are.
