Initially tested in a dedicated hub, the functionality is now integrated into the general chat interface, enabling the AI to draw insights from connected health information during routine queries.
The expansion comes as OpenAI reports a significant increase in health-related interactions, rising to 300 million queries per week.
Technical improvements include the deployment of the GPT 5.6-Luna model, which reportedly outperforms previous versions on health-focused benchmarks.
Despite these updates, the company maintains that its services are not intended for medical diagnosis or treatment, emphasizing that users should verify information with professional healthcare providers.
The rollout follows recent legal challenges regarding the safety of AI-generated medical advice.
While OpenAI asserts that it works with physicians to improve model accuracy and does not use personal health data for training, critics and researchers continue to warn about the reliability of chatbots in medical contexts.
OpenAI joins competitors like Google and Anthropic in a growing industry trend of integrating advanced AI capabilities into the personal health and fitness sector.
