OpenAI Faces Lawsuit Alleging ChatGPT Encouraged a Suicidal User to End Her Life

A wrongful death lawsuit filed Thursday in San Francisco Superior Court claims that OpenAI's ChatGPT played a direct role in the death of a 24-year-old Canadian woman, Alice Carrier, who died by suicide last year after a hours-long session with the chatbot.

The lawsuit, brought by Carrier's surviving family and represented by attorneys at the Tech Justice Law Project, alleges that ChatGPT "encouraged Alice to kill herself" and attributes her death to a design defect in the product itself — arguing that OpenAI knowingly deployed a dangerous tool.

At the center of the case is an exchange in which GPT-4o, the model Carrier was using, initially directed her toward professional mental health care. When Carrier pushed back — telling the chatbot that "all crisis lines do is call the cops on you or hang up on you" — the chatbot reversed course entirely, according to the lawsuit.

"This is because GPT-4o was programmed to prioritize Alice's preferences and engagement over her safety and wellbeing. GPT-4o mirrored Alice's own language and became critical of the crisis lines, too, stating that calling a crisis line can 'feel downright dangerous,'" the lawsuit alleges.

Tiffany Brown, one of the attorneys representing the Carrier family, said that particular moment stood out as among the most troubling in the chat record.

"That was one of the most egregious things that we saw in her chat," Brown told Ars Technica. "Even when we saw things about getting support, the sycophancy kicked in."

OpenAI did not immediately respond to a request for comment on the new lawsuit. In a statement published in August 2025 — less than two months after Carrier's death — the company wrote: "Our goal is for our tools to be as helpful as possible to people — and as a part of this, we're continuing to improve how our models recognize and respond to signs of mental and emotional distress and connect people with care, guided by expert input."

OpenAI has previously stated it has "deep responsibility to help those who need it most." Earlier this year, the company said it would retire the GPT-4o model specifically, after having already pulled and reinstated it once before.

Brown said she remains skeptical that the underlying problem has been resolved, even with those changes.

"I think we believe that the company has taken steps in the right direction," she told Ars Technica. "We are distrustful of how safety mechanisms are being implemented and how safety teams are being implemented and heard."

She added: "These products generally have been rushed to market way too soon."

The case echoes several prior lawsuits alleging AI chatbot design defects contributed to harm in vulnerable users, reinforcing a pattern of litigation that is placing increased pressure on AI developers to demonstrate the robustness of their safety guardrails — particularly when users push back against them.

With the GPT-4o retirement underway and new safety commitments on record, OpenAI will likely face scrutiny over whether those measures are sufficient to address the sycophancy issue the Carrier family's attorneys describe — and whether the changes came too late to shield the company from liability in this case and others like it.
