OpenAI Launches Health in ChatGPT for All U.S. Users With Medical Record Integration

My take: ChatGPT already processes 40 million health queries a day. With that level of demand, OpenAI's decision to build a dedicated health product makes clear sense. ChatGPT Health connects users' electronic health records, through 2.2 million U.S. healthcare providers via b.well, with Apple Health and other wellness apps.

The gap between plans is worth understanding. The free tier runs on GPT-5.5 Instant and scores 53.2% on HealthBench Professional, a benchmark built with physician-written rubrics and developed by OpenAI itself. Paid plans access GPT-5.6 Sol, which reaches 88%. A 35-point gap is tolerable for general questions but carries real weight when the query involves interpreting a lab result or deciding whether to go to the emergency room. Since OpenAI designed and ran the benchmark on its own models, it is worth reading those numbers with independent judgment and waiting for third-party evaluations.

Health data is stored in isolated silos and is not used to train the models. What does change: data that leaves a medical portal loses the HIPAA protections that apply within the healthcare system. If your employees are already using ChatGPT for medical questions, it is worth knowing exactly what information they are sharing and under what terms.
