A 31-year-old Chinese woman in Seattle allegedly followed a daily medication-reduction plan from ChatGPT, lowered her anti-seizure medication dose, and died after stopping it. Her parents filed a wrongful-death lawsuit against OpenAI and CEO Sam Altman, alleging that ChatGPT provided dangerous, inaccurate medical advice and practiced medicine without a license. OpenAI said the GPT-4o model involved was removed from its consumer app and stressed that ChatGPT cannot replace medical care.
