Florida pastor Scott Winters filed a lawsuit against OpenAI and CEO Sam Altman in California, accusing them of negligence and alleging the unauthorized practice of medicine. Winters alleges that ChatGPT-4o gave him dangerous medical advice, used Christian religious language and discouraged him from following pleas to seek professional care. According to the lawsuit, Winters suffered a near-fatal pulmonary embolism after weeks of immobility, which doctors said likely contributed to his blood clots. The suit seeks financial damages and asks the court to stop ChatGPT Health from operating until independent evaluators determine it is safe.

Product versus service liability
- ▪OpenAI has previously argued that its technology is a service rather than a product covered by product liability laws, asserting that restricting chatbot topics could violate the First Amendment.

- ▪OpenAI faces a separate wrongful death lawsuit filed in May 2026 by the parents of a 19-year-old who died of a drug overdose after ChatGPT provided detailed advice on drug dosages.
