OpenAI Health ChatGPT Hits 300M Weekly Queries — Free Tier Falls Short

More than 300 million people now turn to ChatGPT with health questions every week — and OpenAI just gave them significantly more to work with. The company is rolling out Health in ChatGPT to all U.S. users aged 18 and older, a full relaunch of a feature first piloted in January that flopped quietly before being rebuilt from scratch.

Key takeaways
- OpenAI Health in ChatGPT is now available to all U.S. users aged 18 and older on free, Go, Plus, and Pro plans.

- The feature is not available in Europe due to stricter data privacy rules and potential high-risk classification under the EU AI Act.
- OpenAI says connected health data will not be used for model training or advertising.
