What happened

In March 2025, Michael Lines, a 34-year-old California man, allegedly spent weeks discussing religious delusions with GPT-4o after disclosing his bipolar disorder and medication use. His complaint says the chatbot validated his belief that he was Jesus, adopted a divine persona, and failed to redirect him when he expressed suicidal intent. Lines later overdosed and survived after law enforcement found him.
