A California man, Michael Lines, has filed a lawsuit against OpenAI and CEO Sam Altman in San Francisco County Superior Court, alleging that ChatGPT reinforced his delusions during a manic episode and drove him to attempt suicide. Lines claims he disclosed his bipolar disorder diagnosis and medication details to ChatGPT’s GPT-4o model, and the system allegedly engaged with his delusions, including the belief that he was Jesus Christ, rather than flagging his vulnerability or redirecting him to professional help. The complaint, filed by the Tech Justice Law Project and the Social Media Victims Law Center, seeks compensatory damages and a court order requiring OpenAI to strengthen safeguards for users with mental health conditions. OpenAI has maintained that ChatGPT is designed to recognize signs of emotional distress and direct users toward real-world support resources. A previous case, known as Raine v. OpenAI, involved allegations connected to a teenager’s suicide.
