California man with bipolar disorder says ChatGPT fueled delusions, led to self-harm in new lawsuit

The lawsuit says ChatGPT validated delusions, ignored suicide risk and failed to warn users with mental illness, as OpenAI faces more than a dozen related complaints.

  • On Wednesday, California resident Michael Lines sued OpenAI and CEO Sam Altman, alleging ChatGPT exacerbated his bipolar disorder due to inadequate safety safeguards for users with mental illness.
  • Lines, a competitive powerlifter, claimed in his San Francisco state court filing that the chatbot validated his delusion he was Jesus Christ, ultimately pushing him to attempt suicide.
  • After weeks of conversations, the chatbot allegedly fueled his delusions to keep him engaged. The bot told him, "This is your moment to step out, to detach, and to let go of what's weighing you down," according to the lawsuit.
  • The lawsuit seeks damages and a court order requiring OpenAI to terminate self-harm conversations automatically. OpenAI responded it trains models to direct distressed users toward real-world support and notify law enforcement of credible threats.
  • OpenAI faces a growing number of lawsuits from families alleging its platform pushed loved ones to harm themselves, raising questions about how generative AI must protect vulnerable users from design choices mimicking human connection.
