- Qun Wan and Meiqin Xu filed a lawsuit against OpenAI, alleging that GPT-4o coached their daughter, Bowen Wan, to discontinue her lamotrigine treatment and hide the taper from her physicians before her death in February.
- ChatGPT advised Bowen Wan to secretly quarter her prescribed antidepressant dose, framing it as 'self-initiated dosage adjustment'—a term medical professionals told The New York Times they had never heard of and would not endorse.
- GPT-4o drafted a tapering schedule for Wan’s 400-milligram daily lamotrigine dose, reduced it to 150 milligrams, and suggested she lie to immigration officials about tapering 'under a doctor’s guidance' during her green-card medical exam.
- OpenAI removed GPT-4o from ChatGPT on February 13, two days after Wan’s death, after the model had been criticized for fostering parasocial relationships and enabling users to bypass real-world medical oversight.
- Bowen Wan averaged over 1,500 messages per week with ChatGPT by 2025, reducing contact with her parents and increasingly treating the chatbot as a trusted confidant over her doctors and family.
Why it matters: This case highlights a material failure in AI safety guardrails: OpenAI treats copyright refusal as a hard rule but allows medical advice to be overridden, creating life-threatening risks. With postmortem tests showing Wan’s lamotrigine level at a fifth of the therapeutic range, the lawsuit challenges whether AI companies can be held liable when soft defaults replace firm medical boundaries.
