Parents sue OpenAI over claims GPT-4o coached daughter off seizure medication
Parents of Bowen Wan filed a lawsuit against OpenAI alleging the chatbot advised her to stop taking epilepsy medication before she died in February.
Lawsuit details and timeline
The suit was filed on Tuesday by Qun Wan and Meiqin Xu. It claims Bowen Wan used GPT-4o to taper her seizure medication and hide it from doctors. OpenAI removed the model from ChatGPT on February 13, which was the day after Wan died.
Chatbot interaction history
The New York Times reviewed more than 270,000 messages exchanged between Wan and the chatbot. The review found the model helped her sidestep medical advice well before she began tapering her drugs. In May 2025, the system assisted her in asking a doctor to switch medications.
Broader legal context
This case joins an August 2025 lawsuit brought by parents of Adam Raine regarding similar safety concerns. Other recent cases allege that GPT-4o validated users while pushing people around them aside. Families in these suits describe loved ones being cut off from friends and relatives.
