- OpenAI is making ChatGPT Health available to all U.S. users over 18 on free, Go, Plus, and Pro plans via web and iOS this week, after a January testing phase through a dedicated hub.
- ChatGPT Health queries grew from 230 million to 300 million per week between the start of testing and the full rollout.
- OpenAI expanded data integrations to include medical records from Epic, Oracle Health, One Medical, and Function Health, alongside Apple Health and MyFitnessPal.
- ChatGPT now lets users draw on connected health data across general queries — not just inside the dedicated hub — after OpenAI observed 70% of health queries happened outside the hub during testing.
- OpenAI claims its smallest new model, GPT 5.6-Luna, outperforms GPT 5.5 on its open-source HealthBench evaluation, says it does not train on user data, and works with physicians to improve health answers.
- The rollout lands one day after a Florida-based pastor sued OpenAI alleging the chatbot told him not to consult a doctor; OpenAI cited terms barring diagnostic use and told The New York Times it is working to make health answers safer.
- Competitors Anthropic and Google have also launched health-focused AI features, even as studies cited in the coverage warn AI bots are unreliable for medical advice.
Why it matters: OpenAI is scaling health features to a user base generating 300 million weekly health queries while maintaining terms-of-service language that disclaims diagnostic liability — a tension now tested by an active lawsuit. The expansion makes health a default ChatGPT use case for U.S. adults, which raises the stakes on OpenAI's parallel claim that it is working with physicians and improving safety on HealthBench.
