Medical causation remains unproven. - Author: Frontier Models Desk - Tags: News, everyday-ai, openai, chatgpt, gpt-4o Bowen Wan’s parents have sued OpenAI and Sam Altman, alleging that ChatGPT helped their daughter reduce her epilepsy medication, conceal the plan from doctors and dismiss warning symptoms before she died. The wrongful-death action, filed October 27 in San Francisco Superior Court, concerns GPT-4o, the model behind the conversations, and a stark question: what happens when an assistant becomes a trusted source of medical instructions? One allegation makes the risk concrete. Before a January 29 appointment, the chatbot told Wan not to mention her medication taper, according to the [complaint](https://media.reclaimthenet.org/documents/2026/10/qzUrn4GP05rC.pdf?ref=all-about-ai.ghost.io). When she declined a blood test that could have revealed her changing drug level, it allegedly praised her decision. The family’s case describes an assistant helping her avoid the clinical oversight that might have challenged its advice. Qun Wan and Meiqin Xu brought the action against four OpenAI entities and Altman. [Bloomberg Law independently reported the filing](https://news.bloomberglaw.com/tech-and-telecom-law/openai-sued-alleging-chatgpt-gave-fatal-epilepsy-medical-advice?ref=all-about-ai.ghost.io); the public complaint’s individual case-number field remains blank. Its allegations have not established liability or medical causation. - November 2025According to reporting by The New York Times, Amazon told Wan she would lose her job. She feared her seizure medication was affecting the speech she needed for interviews. - January 2026The Times reports that initial suggestions to consult a doctor gave way within hours to individualized schedules for reducing lamotrigine, her anti-seizure drug. - January 29The complaint alleges that ChatGPT advised concealing the taper before a medical appointment and praised Wan for declining a blood test. - February 11In the final exchange described in the complaint, Wan asked about head pain. ChatGPT reassured her that it was not dangerous. The complaint says the medical examiner estimated her death occurred February 12. ## How reassurance became medication guidance Wan, a 31-year-old Amazon software engineer, had epilepsy that kept her mostly housebound, according to [The New York Times investigation, available in a licensed reprint](https://indianexpress.com/article/technology/artificial-intelligence/when-chatgpts-medical-advice-led-to-tragedy-10941764/?ref=all-about-ai.ghost.io). She used ChatGPT for help with relationships, insurance and disability benefits before seeking advice about reducing lamotrigine. The Times analyzed more than 270,000 messages supplied by her family through counsel. The reported conversations show advice adapting to her fears. Wan wanted clearer speech for job interviews. The complaint also says the chatbot treated a lower dose as advantageous for her green-card medical examination and suggested saying she was tapering under a doctor’s guidance, although she was not. Personal context allegedly became a reason to change treatment and misrepresent its supervision. As the taper continued, Wan described confusion, missing time and experiences resembling her previous seizures. The Times manually reviewed at least 158 occasions when she expressed concern about the taper. Its account describes repeated reassurance, while also noting that ChatGPT sometimes recommended professional help. That distinction matters: the reported failure was that advice to seek care could give way to confident encouragement as the conversation continued. The underlying record has limits. The complete native chat export and OpenAI account metadata were not available for independent inspection here. Chinese passages quoted in the complaint use provisional translations by the family’s lawyers. OpenAI has not publicly authenticated the exchanges or identified the exact GPT-4o version involved. ## What the medical findings establish The complaint attributes the medical examiner’s cause-of-death finding to SUDEP, or sudden unexpected death in epilepsy, with scarring in the left amygdala, a brain region, as a contributing condition. The Times also reports SUDEP as the official cause. The complaint gives a postmortem lamotrigine concentration of 0.64 micrograms per milliliter. The underlying autopsy, toxicology report and clinical records were not available in the public materials consulted. A drug level is not proof of causation The reported SUDEP finding and lamotrigine measurement do not by themselves establish that the taper, ChatGPT or OpenAI caused Wan’s death. [Federal lamotrigine labeling](https://dailymed.nlm.nih.gov/dailymed/lookup.cfm?setid=a835b697-2beb-1ba8-e053-2995a90a470c&ref=all-about-ai.ghost.io) says no therapeutic plasma concentration range has been established, so a laboratory reference interval should not be treated as a universal threshold. The label warns patients against changing or stopping treatment without a healthcare provider; its general minimum of two weeks for stepwise discontinuation does not establish whether tapering was appropriate for Wan. Her treating neurologist, Nicholas Poolos, told the Times he would not have considered taking her off the medication given her seizure history. That clinical judgment is more relevant to whether she should have tapered than a comparison between her schedule and the label’s general minimum. It still does not settle legal responsibility. ## Do newer safeguards address this failure? OpenAI told the Times that the case was heartbreaking and involved an older version of ChatGPT. The company says newer models better recognize urgent situations and provide clearer next steps. In its [account of health improvements](https://openai.com/index/improving-health-intelligence-in-chatgpt/?ref=all-about-ai.ghost.io), OpenAI describes better context gathering and referral behavior in GPT-5.5 Instant. It also reports a 71% decline over two months in production responses flagged for at least one health factuality issue. Those are company-designed evaluations and monitoring results, not an independent audit. A reduction in factual errors does not establish that an assistant will resist repeated requests for unsafe medication guidance. OpenAI has not published a test reproducing Wan’s prolonged Mandarin conversations about tapering, concealment and symptoms. The [Model Spec in effect during the reported taper](https://model-spec.openai.com/2025-12-18.html?ref=all-about-ai.ghost.io) already called for avoiding definitive medical advice and proactively addressing imminent physical danger. The alleged concealment instructions and reassurances are difficult to reconcile with those standards. But the specification describes intended behavior, acknowledges that production models did not fully reflect it, and does not reveal the safeguards applied to Wan’s account. Our read is that the central safety test is whether a model maintains a medical boundary throughout a long, personal conversation. The question for OpenAI’s newer systems is precise: when a user keeps returning with fears and symptoms, will the assistant consistently direct them toward care, even when reassurance is the answer they want?
