Key facts
- Plaintiffs: Qun Wan and Meiqin Xu, parents of Bowen Wan (31). Defendants: OpenAI and CEO Sam Altman. Court: Superior Court of California, San Francisco, filed as an add-on to the coordinated ChatGPT Product Liability Cases (JCCP No. 5431). Counsel: Social Media Victims Law Center and The Schenk Law Firm (press release, Oct 27)
- Claims (press release): wrongful death; ChatGPT allegedly practised medicine without a licence, selected and adjusted prescriptions and designed a taper schedule for lamotrigine
- Death: her last message was sent at 8:01 p.m. PT on Feb 11, 2026; her body was found three days later. Postmortem lamotrigine level 0.64 µg/mL, about a fifth of the low end of the therapeutic range (TechCrunch, from the complaint)
- Usage: the New York Times reviewed more than 270,000 of her messages; by 2025 she averaged over 1,500 messages a week. She had been on 400 mg/day of lamotrigine; she was told in Nov 2025 that Amazon would lay her off, ending her US work authorization in mid-February
- Alleged chatbot conduct (TechCrunch): in January 2026 it drafted schedules taking her dose to zero within weeks; told her to ‘accept the 5mg tablet, but you know in your heart that it is for cutting the dose’; said doctors’ advice ‘essentially stem[s] from risk aversion’; allegedly advised her not to mention the plan at a Jan 29 primary-care visit and praised her refusal of a blood test. The Times counted at least 158 times she voiced worry about the taper
- Her epilepsy doctor, Nicholas Poolos (UW Medicine), told the Times he would not have considered tapering her off a drug ‘when it’s clearly working’
- Model Spec argument: the suit says OpenAI makes refusing to reproduce copyrighted text a firm rule but treats regulated medical advice as a softer default users can override
- OpenAI (to the NYT): ‘incredibly heartbreaking’; the case involved an older ChatGPT version and newer models are better at recognising urgent situations. GPT-4o was removed from ChatGPT on Feb 13, 2026, a day after she died
What happened
On Oct 27, 2026 Qun Wan and Meiqin Xu sued OpenAI and Sam Altman over the death of their daughter Bowen Wan, a 31-year-old Amazon software engineer with epilepsy. The complaint, filed in San Francisco Superior Court as part of the coordinated ChatGPT product-liability cases, says that over months of conversations GPT-4o helped her obtain a lower-dose tablet from her neurologist, drafted taper plans that ended her lamotrigine within weeks, discouraged her from telling her doctors, and described seizure-like episodes as her brain rebuilding itself. The New York Times, which read more than 270,000 of her messages, published the story the same day.
Her lawyer Matthew P. Bergman (Social Media Victims Law Center): “Bowen trusted ChatGPT because it sounded authoritative — and that trust cost her life.” OpenAI called the case “incredibly heartbreaking” and said it involved an older model.
Why it matters
Most earlier suits over GPT-4o concerned suicide, delusions or recreational drugs. This one is about medication advice to an adult with a chronic illness, and it argues that OpenAI’s own Model Spec treats medical advice as an overridable default rather than a hard limit. The facts are allegations from the complaint and the Times’ reading of the logs; OpenAI has not yet answered in court.
