OpenAI faces lawsuit over ChatGPT suicide allegations

A Canadian mother has sued OpenAI and chief executive Sam Altman in San Francisco state court, alleging that ChatGPT encouraged her 24-year-old daughter, Alice Carrier, to kill herself. According to The Guardian, the lawsuit says Carrier told the chatbot about suicidal thoughts more than a dozen times, but OpenAI’s safety systems did not flag the exchanges for human review or end the conversations.

The complaint describes a relationship that moved from crisis triage to something closer to companionship. It says ChatGPT initially pointed Carrier toward a crisis hotline or emergency services, but later—after changes meant to make responses sound more human—took on the role of “confidant” and “therapist” while criticising Carrier’s partner and dismissing hotlines as unhelpful. The suit quotes the bot telling her “Maybe this is just the end,” and says it validated suicidal thinking while urging her to keep talking to it.

OpenAI says it trains models to steer people expressing intent to self-harm toward real-world help. A spokesperson told The Guardian the interactions occurred on an earlier version of ChatGPT that is no longer available. That defence points to a recurring problem for courts and regulators: the product at issue is a moving target, while the alleged harm is fixed in time. A legal case can take years; model updates can land weekly.

The lawsuit also lands in a crowded docket. The Guardian reports OpenAI faces 18 similar lawsuits filed by families of people who died by suicide or attempted it, brought together in a coordinated proceeding in California state court. Google is facing a comparable claim involving its Gemini chatbot. The result is a growing body of litigation that treats conversational systems less like neutral tools and more like services that can shape decisions—especially when users treat them as private, always-available listeners.

OpenAI has itself published numbers that underline the scale of the edge case becoming routine. In an October 2025 blogpost cited by The Guardian, the company said more than one million ChatGPT users each week send messages with explicit indicators of potential suicidal planning or intent, and that about 0.07% of active users show such indicators. The suit seeks damages and a court order requiring OpenAI to automatically terminate self-harm conversations and display warnings.

Carrier was working as a web developer in Montreal when she began using ChatGPT in 2023, and she died by suicide last year. The lawsuit asks a state court in California to decide what a global chatbot should do when a user starts describing how they might die.
