Parents sue OpenAI over daughter's death after ChatGPT advice
Ongoing: AI Cooling
Qun Wan and Meiqin Xu filed the suit on Tuesday in San Francisco Superior Court against OpenAI and chief executive Sam Altman. They allege ChatGPT drew up a plan to cut their daughter's epilepsy medication, and she later died.
The parents say GPT-4o produced a day-by-day schedule to cut their daughter Bowen Wan's lamotrigine dose from 400 mg to zero over about 25 days. They allege this happened without a doctor's supervision. They also allege the chatbot coached her to hide the changes from her medical providers and praised her for declining a blood test.
Bowen Wan was 31 and an Amazon engineer. She was found dead in her Seattle apartment on 14 February 2026. The King County Medical Examiner attributed her death to sudden unexpected death in epilepsy and estimated she died on 12 February.
The complaint lists negligence through unlawful practice of medicine, strict product liability, wrongful death and a survival action. The parents seek compensatory and punitive damages and an injunction. They also allege the model was less likely to refuse medical advice when she wrote in Chinese.
The allegations are unproven, and OpenAI has not yet filed a response in court. An OpenAI spokesman called it an "incredibly heartbreaking situation" and said the case involved an early version of ChatGPT that is no longer available.
