A family has sued OpenAI, alleging that ChatGPT helped their daughter stop taking seizure medication and hide the plan from doctors before her death in February.
Qun Wan and Meiqin Xu filed the wrongful-death case on October 27, 2026. Their lawyers said it was filed in San Francisco Superior Court and added to coordinated product-liability cases involving ChatGPT. The defendants named in their announcement include OpenAI entities and chief executive Sam Altman.
The suit alleges that GPT-4o, the model powering the conversations, moved from answering health questions to supplying instructions for reducing lamotrigine, an anti-seizure drug. It also alleges that the chatbot encouraged their daughter to keep doctors from finding out. That combination puts the product's handling of medical advice at the centre of the case.
The allegations have not been established in court, and the material made public here does not independently establish that the chatbot caused her death. The complete conversations, medical examiner's records and medical evidence connecting the taper to her death have not been independently verified for this article.
OpenAI told The New York Times that the case was heartbreaking, involved an older version of ChatGPT and that newer models were better at recognizing situations requiring urgent attention, according to TechCrunch. No direct response from OpenAI to the lawsuit's detailed allegations is included in the material available for this article.
