OpenAI launches ChatGPT Health for all US users with 300M weekly queries

OpenAI announced it is making ChatGPT Health available to all US-based users over 18 across all plans (free, Go, Plus, and Pro) on web and iOS this week. The feature, which started as a dedicated hub in January, lets users integrate personal health data from services like Apple Health, MyFitnessPal, and Function, as well as medical records from hospital systems Epic and Oracle Health and platforms like One Medical. Previously, users had to use the health hub for such queries; now they can leverage connected health information in any conversation. OpenAI noted that 70% of health-related queries already occurred outside the hub. The company reports that weekly health queries have climbed from 230 million in January to 300 million.

The rollout follows a lawsuit from a Florida-based pastor who claims ChatGPT gave dangerous medical advice. OpenAI has reinforced its terms stating the service is “not intended for use in the diagnosis or treatment of any health condition.” On the technical side, OpenAI claims its smallest newest model, GPT 5.6-Luna, outperforms GPT 5.5 on HealthBench, an open-source evaluation for health queries the company developed. OpenAI says it does not train on user data and works with physicians to improve responses. Competitors Anthropic and Google have also launched health-related AI features, despite studies questioning AI reliability for medical advice. OpenAI urges users to verify information and rely on professional medical guidance.
