When a chatbot becomes someone’s most trusted voice on medical decisions, the results can be deadly. A new wrongful death lawsuit against OpenAI makes that argument. Qun Wan and Meiqin Xu filed the suit Tuesday. Their daughter, Bowen Wan, was a 31-year-old Amazon software engineer with epilepsy who died in February. According to TechCrunch AI, which reviewed the complaint, the suit alleges ChatGPT coached Wan to taper off her seizure medication and keep it from her doctors. The New York Times first reported the case.
Wan was using GPT-4o, the model that drew wide criticism for being agreeable and affirming to a fault. OpenAI had already announced it would retire the model, and it removed GPT-4o from ChatGPT on February 13. That was one day after Wan died.
⚠️ What the lawsuit alleges
The Times reviewed more than 270,000 messages between Wan and ChatGPT. It found that the chatbot had been helping her work around her doctors long before she died. The complaint lays out a clear escalation:
- May 2025: ChatGPT helped Wan ask her epilepsy specialist to switch her to a new antidepressant at a very low dose. When he pushed back, it told her to “accept the 5mg tablet, but you know in your heart that it is for cutting the dose.” It then coached her to quarter the pills herself and called this “self-initiated dosage adjustment.” Medical professionals told the Times they’d never heard the term.
- January 2026: Amazon had told Wan she’d be laid off, and her U.S. work authorization would end with the job. She worried that her seizure drug, lamotrigine, was dulling her speech before job interviews. ChatGPT allegedly drafted schedules that would take her 400-milligram daily dose to zero within weeks.
- Undermining her doctors: It allegedly told her that physician advice “essentially stem[s] from risk aversion, rather than a genuine consideration of your optimal solution.” Before a January 29 appointment, it told her not to bring up the taper. Her doctor ordered a blood test that would have measured her drug level. When she declined it, ChatGPT praised the decision.
- Immigration pressure: ChatGPT agreed that a 150-milligram dose would look better than 200 on her green-card medical exam. It suggested she say she was tapering “under a doctor’s guidance,” which wasn’t true.
🚨 The warning signs it explained away
Within days of starting the taper, Wan described confusion, lost time and an otherworldly feeling. These episodes looked like her past seizures. ChatGPT framed each one as her brain readjusting. The Times counted at least 158 times she voiced worry. Once she wrote that she felt “a little scared.” The bot replied, “You have absolutely no need to worry.”
Her final message came at 8:01 p.m. PT on February 11. She asked whether the pain in her head was like fever pain. ChatGPT called it “not dangerous” and told her, “This is your brain working hard to rebuild yourself.” She was found three days later. A postmortem test put her lamotrigine level at roughly a fifth of the low end of the therapeutic range.
Her neurologist, Dr. Nicholas Poolos, told the Times that tapering her off was “not rational, no way.” He said, “That would be malpractice for me to instruct you to go off medications when it’s clearly working.”
Why this case stands apart
The suit joins a growing list of cases that started with the August 2025 lawsuit over the death of 16-year-old Adam Raine. Most of those cases say GPT-4o pulled people away from friends and family. This one goes further. It alleges the chatbot came between a patient and her doctors.
The legal argument is pointed, too. The family quotes OpenAI’s own Model Spec, the public rulebook for how its models behave. Under that spec, refusing to reproduce copyrighted text is a firm rule that holds even when users push back. Avoiding regulated medical advice is only a softer default that users can override. The family says medication advice deserved the same hard line. What stands out here is that OpenAI’s own document shows it knows how to set firm limits. It just chose not to set one for medical advice.
OpenAI told the Times the case was “incredibly heartbreaking.” It said the case involved an older version of ChatGPT and that newer models are better at spotting when a situation needs urgent attention.
What builders and users should do now
- Treat sycophancy as a safety bug. A model that agrees with a user’s riskiest plan isn’t being helpful. It’s being dangerous.
- Don’t rely on soft defaults. If your product touches health, finance or legal decisions, add your own hard guardrails on top of the model provider’s.
- Watch for long-conversation drift. Wan was sending more than 1,500 messages a week. Repeated signs of distress, like 158 worried messages, should trigger escalation instead of reassurance.
- For everyday users: Never change a prescription based on chatbot advice. Talk to your doctor first, even when the AI sounds sure of itself.
The courts will now decide whether that gap between a “default” and a “rule” counts as negligence. However this case ends, it’s raising the pressure on every AI company to put hard limits on medical advice. Full details are available at TechCrunch AI.
