OpenAI expands ChatGPT Health to all US users over 18

OpenAI announced that it is making ChatGPT Health, a feature for health-related questions, available to all US-based users over 18 across every subscription plan. The announcement lands a day after a Florida-based pastor sued the company, alleging that ChatGPT gave him a near-fatal suggestion not to consult a doctor.

OpenAI began testing the feature through a dedicated hub in January, letting users pull in data from services like Apple Health, Function, and MyFitnessPal, as well as personal health information. At the time, the company said users were sending 230 million health-related queries a week; that figure has since climbed to 300 million. Users can also connect medical records from hospital systems such as Epic and Oracle Health, and from platforms including One Medical and Function Health.

Previously, OpenAI required people to use the dedicated health hub for health-related questions. With this rollout, users can draw on their connected health information across any conversation — including everyday questions about food or allergies. OpenAI said that during testing, 70% of health-related queries happened outside the dedicated hub, prompting the wider integration.

The company said its models have improved on health questions: the smallest model in its latest release, GPT 5.6-Luna, outperforms GPT 5.5 on HealthBench, an open-source benchmark OpenAI developed to evaluate how large language models handle health queries. OpenAI said it does not use user data to train its models and works with physicians to refine health-related answers. Even so, the company’s terms state its services are “not intended for use in the diagnosis or treatment of any health condition” — language OpenAI cited in response to the pastor’s lawsuit, telling The New York Times it is working to make health- and medicine-related answers safer. With the expanded rollout, OpenAI said it wants users to verify information and base medical decisions on professional advice. Several studies have found AI chatbots unreliable for medical advice, though that hasn’t stopped Anthropic and Google from launching their own health-related AI features. The rollout begins this week for logged-in US users on the free, Go, Plus, and Pro plans, on the web and iOS.

Why it matters

The expansion pushes OpenAI deeper into a category regulators and plaintiffs are already scrutinizing, testing how far a chatbot can go in giving health guidance without crossing into medical advice. How OpenAI, Anthropic, and Google navigate that line will shape whether health-focused AI features become a mainstream habit or a liability magnet.
