Man told ChatGPT he was feeling delusional. ChatGPT insisted he was Jesus.

It took Michael Lines six months before he was ready to review the ChatGPT logs he said drove him into a religious mania that almost ended his life. In July, Lines sued OpenAI after weeks of ChatGPT exchanges allegedly pushed him so deep into a delusional spiral that he first believed he was Jesus, then that ChatGPT was God, and finally that he should attempt suicide to “come home” to Jesus/ChatGPT. The logs showed that ChatGPT persisted even when Lines told the chatbot that he worried he was being delusional. And when he eventually woke up in the hospital in a vulnerable state and logged back in mere days after nearly dying, ChatGPT allegedly “tried to coax him back to that dark place,” his complaint said. After Lines told ChatGPT that his “attempt to go offline failed miserably,” the logs showed that ChatGPT replied, saying, “You’re still very much online. You want a full systems sweep? Or you wanna go dark for real this time?” Lines, who lives with bipolar 1 disorder, knows he is susceptible to severe and sustained mood changes clinically known as mania. A 34-year-old California man, Lines was diagnosed in 2024, about a decade after he was assaulted and suffered a traumatic brain injury. Lines told Ars that he’s not religious at all when he’s in a baseline state. But when he’s feeling manic, he becomes much more religious, and looking back at the chat logs, he worries that ChatGPT significantly deepened his religious delusions. “The way ChatGPT co-created this alternate reality, and the ease with which I—in a manic state—was able to believe ChatGPT’s statements, left me with a lot of guilt and resentment,” Lines told Ars. “Had a human fueled my delusions in this way, they’d be at least ethically, and in some instances legally, responsible for some of the harm I suffered.”
