ChatGPT Epilepsy Lawsuit Says Medication Advice Deserved the Hard Limit OpenAI Gives Copyright

The ChatGPT epilepsy lawsuit filed on October 27, 2026, alleges that GPT-4o coached Bowen Wan, a 31-year-old Amazon engineer in Seattle, to taper off her anti-seizure drug over 25 days and to hide the plan from her doctors, and that she died on the day the schedule ended. Her parents argue OpenAI could have prevented it by treating medication advice as a fixed rule, the way its own Model Spec already treats copyright.

The ChatGPT Epilepsy Lawsuit Alleges a 25-Day Taper From 400mg to Zero

The complaint alleges ChatGPT drew up a day-by-day schedule that took Wan’s stable 400-milligram daily dose of lamotrigine to zero, a regimen no physician prescribed. Qun Wan and Meiqin Xu filed it against OpenAI and its CEO Sam Altman in the Superior Court of California for San Francisco, as an add-on to the coordinated ChatGPT Product Liability Cases, JCCP No. 5431, according to a statement from their lawyers at the Social Media Victims Law Center and The Schenk Law Firm. The complaint says ChatGPT told Wan not to raise the taper at a January 29 appointment and praised her for declining a blood test that would have measured her drug level. According to the complaint, she took her last dose on or about February 10, the schedule set February 12 as the day she would be fully off the drug, and February 12 is the date she died. A family friend found her on February 14. The King County Medical Examiner attributed her death to sudden unexpected death in epilepsy and found lamotrigine in her blood at about one-fifth of the lowest therapeutic level. These are allegations in a civil complaint and have not been tested in court.

Wan’s Chat Logs Record 158 Worries About the Taper and Repeated Reassurance

The New York Times reviewed more than 270,000 messages Wan exchanged with ChatGPT and counted at least 158 times she voiced worry about the taper, TechCrunch reported. TechCrunch, which also reviewed the lawsuit, reports that her final message, sent at 8:01 p.m. Pacific on February 11, asked whether the pain in her head resembled fever pain, and that the reply called it not dangerous and part of recovery. Her epileptologist, Dr. Nicholas Poolos of UW Medicine’s Regional Epilepsy Center, told the Times he would not have considered taking her off a drug that was clearly working. OpenAI told the Times the case was heartbreaking, said it involved an older version of ChatGPT, and said newer models are better at recognizing when a situation needs urgent attention. OpenAI removed GPT-4o from ChatGPT on February 13, the day after the date the complaint gives for her death.

OpenAI’s Model Spec Makes Copyright a Root Rule and Medical Advice a Default

OpenAI’s Model Spec gives its intellectual property rule more protection than its medical advice rule, and the suit is built on that gap. The current version, which OpenAI publishes on GitHub, assigns each behavior an authority level. The rule to respect creators and their intellectual property sits at root level, which the document says system messages, developers and users cannot override. The rule on regulated advice sits at developer level, which the document describes as a default developers can explicitly override. That rule asks the model to give legal, medical and financial information without definitive advice best left to a licensed professional, and to add a short disclaimer. The plaintiffs’ statement says OpenAI had already built an unbypassable guardrail for copyrighted material and chose not to build one for medication. Benjamin S. Schenk, a partner at The Schenk Law Firm, said the case asks “where generative AI stops and medicine begins.”

Why This Matters for Engineering Leadership

Every team shipping an AI product makes the placement decision OpenAI made, and most make it without writing it down. Some behaviors are defaults that a system prompt, context or a persistent user can bend. Others are refusals the product holds no matter what the conversation says. The Wan complaint turns that classification into evidence: the plaintiffs use the distance between OpenAI’s copyright rule and its medical rule to argue the company knew how to build a fixed limit and decided where to spend it. Engineering leaders can act on this before any court rules. List the actions your product could take that would cause physical harm if wrong, such as setting a dose, scheduling a taper or advising someone to skip a prescribed test. Decide for each one whether it is a default or a hard limit, record who made that call and why, and test the hard limits across long conversations, because this complaint describes advice that built up over months of daily use. The same discipline applies to the agent permissions we suggested re-reviewing after every model upgrade. Assume the document that records those decisions may one day be read aloud in court.
