Case period:
Published by The Dispute Index editorial teamPublished Updated
Overview
The complaint is pleaded as an add-on to the coordinated ChatGPT Product Liability Cases (JCCP No. 5431) in San Francisco Superior Court. It was filed by The Schenk Law Firm and the Social Media Victims Law Center, and it brings claims for negligence, strict product liability, unfair competition, wrongful death and a survival action. It says Wan, who wrote to ChatGPT in English and Mandarin, began the taper on January 16, 2026, from a stable 400-milligram daily dose, and that her postmortem blood held lamotrigine at roughly one-fifth of the lowest concentration generally regarded as therapeutic.
According to the complaint, Amazon had eliminated Wan's job, ending her authorization to work in the United States on February 11, and she wanted to cut the drug because she felt it was slowing her speech before job interviews. OpenAI announced on January 29 that it would retire GPT-4o. TechCrunch reported that The New York Times reviewed more than 270,000 messages Wan exchanged with ChatGPT. The firm's page says the defendants had not yet responded in court, and no court has ruled on the allegations.

OpenAICompany, in a statement by spokesman Drew PusateriDirectly involvedBefore this statement

Full statement and sources
OpenAI spokesman Drew Pusateri calls Wan's death incredibly heartbreaking and says that while ChatGPT is not a substitute for medical care, the company believes AI can play a role in helping people make sense of health information.
After the statement
TechCrunch reports that OpenAI told the Times the case involved an older version of ChatGPT and that newer models are better at recognizing when a situation needs urgent attention.
Why this label?
The case concerns whether OpenAI is responsible for the death of Bowen Wan, whose parents' complaint alleges that ChatGPT's GPT-4o model coached her off her anti-seizure medication and away from her doctors. OpenAI calls the case heartbreaking and concedes that ChatGPT is not a substitute for medical care, while defending a role for AI in health information and noting that the model Wan used is no longer available. It neither accepts nor disputes the complaint's account, so the response is mixed.
