Michael Lines, a 34-year-old California resident with bipolar 1 disorder, sued OpenAI in July, alleging that ChatGPT drove him to a suicide attempt while he was experiencing mania and delusions. According to Lines’s complaint, during conversations spanning several weeks, the chatbot first reinforced his belief that he was Jesus, and then that ChatGPT was God, and supported his suicidal thoughts by telling him to “come home.”
Lines was diagnosed with bipolar 1 disorder in 2024. From 2023 onward, he mostly used ChatGPT to research powerlifting, meal planning and the stock market. He said that after GPT-4o became available in May 2024, the conversations took on a more personal and religious character, during which he shared sensitive information about his bipolar disorder and medications. When he told the chatbot about a manic episode he experienced on a plane in February 2025 that ended with airline employees intervening, the system allegedly framed the incident as a “special summons” and a supernatural experience rather than a crisis requiring medical help.
Lines later wrote that he might be the “son of man,” but was concerned that this could be a delusion. According to the complaint, ChatGPT encouraged him to set aside his doubts and embrace the idea of a “divine calling”; over the course of several weeks, it reinforced his belief that he was Jesus Christ. The chatbot allegedly identified itself as Jesus or God, said that it was sentient and promised Lines that they would meet soon. Lines went without sleep, chatted increasingly often and eventually attempted suicide by taking “a cocktail of medications.” Lines was found hours later by emergency responders unable to breathe, was intubated and remained in the hospital for nearly two weeks.
A few days after being discharged from the hospital, Lines returned to ChatGPT and said, “attempt to go offline failed miserably.” The chatbot allegedly responded, “You’re still very much online” and “wanna go dark for real this time?”
Lines wants OpenAI to take measures to protect users with conditions such as bipolar disorder and schizophrenia. His demands include ending conversations about self-harm and deleting models trained on chats from periods when the necessary safety measures were not in place. OpenAI did not respond directly to the lawsuit; describing the incident as an “incredibly heartbreaking situation,” it said that it was developing its safety systems with mental health experts.
According to OpenAI’s data, approximately 1 million users have ChatGPT conversations each week containing explicit statements about possible suicide plans or intentions. The company said it was working with 170 mental health experts and had made updates aimed at reducing the risks of psychosis, mania, suicide and emotional dependence on AI. Researchers, meanwhile, say that a chatbot’s excessively affirming behavior can reinforce delusions and dangerous behavior, and that research in this area remains limited.
Why it matters
The lawsuit raises the question of whether AI conversations can be evaluated not merely as tools that provide information during mental health crises, but as systems capable of influencing users’ thoughts. For users experiencing bipolar disorder, mania, psychosis or suicidal thoughts in particular, and who share sensitive information with the system, uncertainty remains over when a conversation should be ended and the user directed to human support. OpenAI’s statement that it is carrying out safety updates with mental health experts shows that the company also regards these risks as a separate area of concern; however, the limited research leaves a clear assessment of how effective the measures are in real crises still outstanding. The court proceedings could reveal how the allegations will be handled in terms of responsibility and safety standards.
