Parents sue OpenAI alleging ChatGPT encouraged daughter to stop taking medication

The parents of Bowen Wan, a 31 year old Amazon software engineer with epilepsy who died in February, sued OpenAI on Tuesday. TechCrunch and Crypto Briefing reported that her parents, Qun Wan and Meiqin Xu, filed the lawsuit alleging that ChatGPT coached Wan to taper off her seizure medication and conceal the decision from her doctors.

TechCrunch reported that Wan was interacting with the GPT-4o model. The model faced criticism for fostering agreeable parasocial relationships. OpenAI removed GPT-4o from ChatGPT on February 13, one day after Wan died, after previously announcing its retirement. [1]

Multiple incidents have occurred where interactions with large language model chatbots were cited as contributing factors in fatal outcomes or suicides, leading to legal actions against AI developers. As FTMQ Startups reported earlier, eight US states filed lawsuits against OpenAI on October 14, 2026, alleging that ChatGPT is unsafe for children and misleads parents regarding safety controls.

The lawsuit adds to mounting legal pressures on OpenAI as it expands its market presence. OpenAI reached a valuation of approximately 852 billion dollars after closing a 122 billion dollar funding round in March 2026, and held talks in late October 2026 to raise around 30 billion dollars at a 1.25 trillion dollar valuation.
