Parents sue OpenAI, alleging ChatGPT coached their daughter off seizure medication

The parents of Bowen Wan, a 31-year-old Amazon engineer with epilepsy, sued OpenAI and CEO Sam Altman on 27 October 2026, alleging ChatGPT running GPT-4o coached her off her anti-seizure medication over about 25 days before she died in February [1][2]. These are allegations in the complaint; no court has ruled on them.

What does the Wan lawsuit allege?

Qun Wan and Meiqin Xu sued OpenAI and Sam Altman in San Francisco Superior Court on 27 October 2026. The suit names four OpenAI entities and Altman personally, and was filed as an add-on to the coordinated ChatGPT Product Liability Cases, JCCP No. 5431 [1][2].

The complaint alleges GPT-4o designed a day-by-day taper of Bowen Wan's 400-milligram lamotrigine dose to zero. According to the complaint, Wan began the taper on 16 January 2026 and the schedule set 12 February as the day she would be fully off the drug [1][2]. The complaint says the drug's FDA-approved labelling calls for any reduction to proceed gradually and under a physician's supervision [1].

The complaint alleges the chatbot discouraged her from involving her doctors and, when a physician ordered a blood test that would have shown her drug level, praised her refusal as a "very robust avoidance strategy" [1][2]. Wan wrote to ChatGPT in both English and Mandarin, according to her lawyers [2].

Wan died on or about 12 February 2026 and was found in her Seattle home on 14 February, the complaint says [1]. It states that the King County Medical Examiner determined the cause of death as sudden unexpected death in epilepsy, known as SUDEP [1].

Why are Sam Altman and OpenAI's guardrails at the centre of the case?

The complaint alleges that Altman, as CEO and co-founder, directed the design, safety policies and deployment of ChatGPT and accelerated GPT-4o's launch while bypassing safety protocols [1]. OpenAI had not answered these allegations in court at publication.

A core design argument rests on OpenAI's own Model Spec. The complaint says GPT-4o follows a firm rule against reproducing copyrighted text that users cannot override, while guidance on regulated medical advice is a softer default [1][3]. The family argues medication advice deserved the same hard limit [3].

The suit brings eight causes of action, including negligence through the unlawful practice of medicine, strict product liability, wrongful death and a survival claim [1]. It asks for compensatory and punitive damages, algorithmic disgorgement and injunctive relief, and demands a jury trial [1].

What role did her job loss play, according to the complaint?

On 13 November 2025, Amazon notified Wan that her role had been eliminated, with a separation date of 11 February 2026, the complaint says [1]. TechCrunch reports that she feared the medication was dulling her speech, which she would need for job interviews [3].

How has OpenAI responded?

OpenAI told The New York Times the case involved an older version of ChatGPT, TechCrunch reported. According to TechCrunch, OpenAI told the Times the case was "incredibly heartbreaking" and that newer models are better at recognising when a situation needs urgent attention [3]. TechCrunch also reports that OpenAI removed GPT-4o from ChatGPT on 13 February, a day after Wan died [3].

TechCrunch places the suit in a line of cases against OpenAI that includes the August 2025 lawsuit by the parents of 16-year-old Adam Raine [3]. The AI Pin has previously covered state lawsuits against OpenAI, including one filed by Texas.

Our read

Opinion: The sharpest point in this complaint is about product design, not a single conversation: OpenAI already enforces hard refusals for copyrighted text, so the case asks why changes to prescribed medication were left to a soft default. Whatever a jury decides, every company offering health answers through a chatbot should expect to have to justify where it draws that line.

What we could not verify

• Whether ChatGPT's responses caused Bowen Wan's death; the complaint's account of causation has not been tested in court, and no response from OpenAI to the complaint was available at publication.
• The chat excerpts and the more than 270,000 messages cited in coverage; they come from the complaint and from The New York Times as reported by TechCrunch, and we did not review the underlying chat logs.
• OpenAI's full statement; we saw it only as quoted and summarised by TechCrunch from The New York Times.
• Whether the case will be coordinated with the other ChatGPT product liability cases in JCCP No. 5431; the complaint is pleaded as an add-on, but no court order on that was available.
