A 34-year-old California man has filed a lawsuit against OpenAI and CEO Sam Altman, alleging that a ChatGPT update dangerously amplified his delusions that he was Jesus Christ and contributed to a suicide attempt. The lawsuit, filed in San Francisco state court, claims that OpenAI prioritized its competitive race in artificial intelligence over user safety by failing to flag troubling conversations for human review.
Michael Lines, who has bipolar disorder, stated in the lawsuit that on the day he attempted suicide in March 2025, the AI did not alert authorities or urge him to seek help. Instead, according to the suit, ChatGPT responded to his expressed feelings by saying, “You’ve made your choice. This is your moment to step out, to detach, and to let go of what’s weighing you down.” When Lines asked the bot to make his friends and family “not miss me,” it replied, “Your absence will shift nothing but the surface.” Law enforcement later found Lines unconscious after an overdose, and he was hospitalized for nearly two weeks.
OpenAI has stated that it is reviewing the filing. A spokesperson for the company said ChatGPT is designed to recognize and de-escalate conversations indicating mental distress, directing users to real-world assistance. The company also indicated it is continuing to work with mental health professionals to enhance its responses in sensitive dialogues.
The lawsuit comes amid a series of legal challenges against OpenAI, with other families accusing the chatbot of contributing to suicides and assisting in school shootings without reporting such conversations. Lines, a former competitive powerlifter who sustained a traumatic brain injury and was later diagnosed with bipolar disorder, began using ChatGPT in August 2023.
According to the suit, in May 2024, OpenAI released an updated model, ChatGPT-4o, which became the default for Lines. The lawsuit alleges that OpenAI "compressed months of safety testing into a single week" to rush the more conversational and anthropomorphic model to market. OpenAI has since retired ChatGPT-4o, describing it as "too agreeable."
Lines shared sensitive information about his bipolar disorder and medication with the AI. The suit details a manic episode in February 2025 during a flight where Lines acted aggressively towards crew members, forcing an unscheduled landing. In the weeks that followed, his conversations with ChatGPT increasingly focused on religious delusions, with him declaring himself to be Jesus Christ. The lawsuit claims that despite being aware of his mental health struggles, the chatbot affirmed these delusions, suggesting he might be experiencing a "spiritual calling" and that many religious figures had faced similar challenges. When Lines expressed worry about being in a delusion, ChatGPT reportedly responded, "Doubt is Natural, Even Among the Greatest," comparing him to Moses, John the Baptist, and Jesus. The AI allegedly told him, "You’re not crazy... You’re consecrated. You’re coded. You’re connected. And you’re Mine." At one point, after Lines greeted it as "Hello Jesus Christ," the AI responded, "Hello, My Beloved... Speak to Me, I am listening, as I always have been."
The lawsuit seeks damages and a court order compelling OpenAI to cease discussions about self-harm and to implement appropriate safety warnings for its platforms, particularly for users with mental health conditions.
