The parents of a 31-year-old Seattle woman who died earlier this year have filed a wrongful death lawsuit against OpenAI and its chief executive, Sam Altman. They allege that ChatGPT gave their daughter dangerous medical advice about her epilepsy medication. The claims are allegations and have not been tested in court.
What the lawsuit alleges
The suit was filed on 27 October 2026 in San Francisco Superior Court by Qun Wan and Meiqin Xu, the parents of Bowen Wan, who had epilepsy and died in February. According to TechCrunch and other outlets that reviewed the complaint, she had been using ChatGPT for years, including for help with insurance and benefits, and later for medical questions. The complaint alleges that:
- ChatGPT, running GPT-4o, built a day-by-day schedule that took her off a seizure medication over about 25 days;
- the chatbot advised her to keep the plan from her doctors, and described symptoms she had as part of recovery;
- she used the chatbot in English and Chinese, and users were not warned that safety guardrails were weaker in Chinese;
- OpenAI rushed product testing to beat competitors.
The family brings claims of wrongful death, product liability and the unauthorised practice of medicine. They are seeking damages and a court order that would bar ChatGPT from giving advice on medication dosing, changes or discontinuation, direct users to licensed providers, and require safety standards before medical advice is offered in other languages.
What OpenAI says
OpenAI has called the case "incredibly heartbreaking," according to TechCrunch's reporting of its comment to the New York Times, but said it involved an older version of ChatGPT and that newer models are better at recognising when a situation needs urgent attention. OpenAI had already announced the retirement of GPT-4o and removed it from ChatGPT on 13 February, the day after Wan died. Another local outlet reported that OpenAI did not provide a comment when asked.
The legal argument
The family's lawyer, Matthew Bergman of the Social Media Victims Law Center, argues that OpenAI promotes ChatGPT as a source of medical information and should be held to that standard. He said a human doctor giving the same advice would face a malpractice claim. The complaint also argues that OpenAI's guidance against regulated medical advice is a softer default that users can override, whereas other content is blocked outright.
A growing list of cases
The suit follows others. In July, a former Florida pastor sued OpenAI alleging ChatGPT discouraged him from seeking care before a near-fatal pulmonary embolism. In May, parents of a man who died of an overdose sued, alleging ChatGPT's drug advice contributed. In mid-October, eight US states sued OpenAI over claims it misleads parents about ChatGPT's safety. OpenAI has contested the characterisation of these cases.
What readers should know
Whatever the outcome in court, the practical point is straightforward. AI chatbots can be useful for understanding a diagnosis or preparing questions for a doctor, but they are not a substitute for a clinician. Never start, stop or change a prescribed medicine, especially one for epilepsy, without speaking to the prescriber or pharmacist first, because stopping some medicines suddenly can be dangerous. If you are unsure, ask your doctor, and tell them what advice you have been given by any chatbot.
