OpenAI Expands ChatGPT Health to All U.S. Users Following Rapid Growth

OpenAI has announced the wide-scale release of ChatGPT Health to all U.S.-based users over the age of 18 across all subscription tiers. This expansion marks a significant shift in how consumers interact with generative AI for personal wellness and medical data management.

Integrating Personal Data and Medical Records

The rollout moves beyond simple text-based queries by allowing users to integrate deeply personal health data into their conversations. Users can now connect information from wearable services and fitness platforms like Apple Health, Function, and MyFitnessPal.

Crucially, the update enables the integration of official medical records from major hospital systems, including Epic and Oracle Health, as well as digital health platforms like One Medical. While OpenAI previously required users to use a dedicated "health hub" for medical inquiries, the new feature allows users to draw insights from their connected health data during general chat sessions. This allows for highly contextualized queries, such as asking about food allergies or nutritional needs based on real-time physiological data.

The demand for AI-driven medical information is surging. OpenAI reported that health-related queries have grown from 230 million to 300 million per week since testing began in January. During the pilot phase, the company observed that 70% of health-related queries were being conducted outside the dedicated health hub, prompting the decision to integrate these capabilities into the main chat interface.

However, this expansion comes at a sensitive time. The move follows a lawsuit from a Florida-based pastor who alleged the model provided near-fatal advice by suggesting he forgo a doctor's consultation. In response to such risks, OpenAI maintains strict legal disclaimers, stating that its services are "not intended for use in the diagnosis or treatment of any health condition." The company is currently working on making medical-related answers safer and emphasizes that all information should be verified by professionals.

Benchmarks and Technical Advancements

On the technical front, OpenAI is leveraging improved model architectures to handle the complexities of medical reasoning. The company highlighted that its latest small-scale model, GPT 5.6-Luna, outperforms the previous GPT 5.5 iteration on HealthBench—an open-source benchmark specifically designed to evaluate LLMs on health-related accuracy.

To ensure accuracy and safety, OpenAI collaborates with physicians to fine-tune its models. Furthermore, the company addressed privacy concerns by stating that it does not use any user health data to train its underlying models. This development places OpenAI in direct competition with other tech giants like Google and Anthropic, who are also aggressively pursuing the specialized AI healthcare vertical.

Key Takeaways

  • Deep Integration: Users can now sync medical records from Epic and Oracle Health alongside fitness data from Apple Health and MyFitnessPal for contextualized AI insights.
  • Rapid Growth: Health-related queries on ChatGPT have surged to 300 million per week, driving the transition from a dedicated hub to integrated general chat capabilities.
  • Safety & Benchmarking: Despite legal challenges, OpenAI is utilizing the new GPT 5.6-Luna model, which shows improved performance on the HealthBench evaluation metric.
