Scott Winters, a former Florida pastor, sued OpenAI and CEO Sam Altman in San Francisco court on Wednesday, alleging that ChatGPT-4o gave him medical guidance that delayed treatment for a pulmonary embolism. Winters consulted the chatbot for months about dizziness and blood pressure instability, and it told him to stay home and rest in a recliner rather than see a doctor, according to the complaint. A physician who treated him later attributed the blood clots in part to that prolonged inactivity, the suit claims. Winters is seeking damages along with a court order suspending ChatGPT Health, which invites users to upload medical records, pending an independent safety review. OpenAI spokesperson Drew Pusateri said ChatGPT is not a doctor and should never substitute for medical care, diagnosis, or treatment.
