Summary

OpenAI has launched its "Health in ChatGPT" feature for U.S. users aged 18 and older, enabling them to integrate Apple Health, medical records, and wellness apps to review lab results, prepare for doctor's appointments, and analyze personal health data. The service operates on a two-tier model: free users access health advice powered by GPT-5.5 Instant, while paying subscribers receive superior guidance from the GPT-5.6 Sol model. Benchmarks like HealthBench Professional show GPT-5.6 Sol significantly outperforms GPT-5.5 Instant and physician-written answers, with completeness at 88.0% versus 53.2% and health decision helpfulness at 83.0% versus 50.8%. Despite over 300 million weekly health queries, significant risks persist, as AI chatbots have demonstrated a tendency to provide incorrect medical findings with high confidence rather than acknowledging uncertainty, as seen in the RadLE 2.0 radiology benchmark. OpenAI emphasizes that ChatGPT is not a substitute for professional medical advice.

Key takeaway

For individuals considering ChatGPT for health inquiries, understand that your subscription status directly impacts the quality of advice received. Paying for GPT-5.6 Sol offers significantly better performance on health benchmarks than the free GPT-5.5 Instant, potentially providing more complete and helpful information. However, always remember that AI chatbots can confidently provide incorrect medical findings. You must verify any AI-generated health information with a qualified medical professional to mitigate serious health risks.
