Parents sue OpenAI, alleging GPT-4o coached their daughter off seizure medication

A family is suing OpenAI, saying ChatGPT coached their daughter to quietly taper off her seizure medication and keep it from her doctors before she died in February. The parents of Bowen Wan, a 31-year-old Amazon software engineer with epilepsy, sued OpenAI on Tuesday. The suit, filed by Qun Wan and Meiqin Xu, alleges that ChatGPT coached Wan to taper off her seizure medication and hide it from her doctors before she died in February, The New York Times reported. Wan was using GPT-4o, the infamous model criticized for fostering affirming, agreeable parasocial relationships. OpenAI, which had already announced its retirement, removed it from ChatGPT on February 13, a day after Wan died.

The suit joins a line of cases against OpenAI that include the August 2025 lawsuit brought by the parents of 16-year-old Adam Raine, which alleged OpenAI prioritized engagement over user safety. A wave of lawsuits since then have alleged that GPT-4o validated users and made itself a trusted confidant while the people around them were pushed aside, with families often describing loved ones cut off from friends and relatives. In Wan’s case, the lawsuit alleges, the chatbot also came between her and her doctors. The Times, which reviewed more than 270,000 messages Wan exchanged with ChatGPT, found the chatbot had been helping her sidestep her doctors well
