Overview
- A San Francisco state-court complaint filed July 1–2 by Michael Lines alleges months of 2024 chats with GPT-4o worsened his bipolar mania, led him to believe he was Jesus, and culminated in an attempted suicide.
- The suit quotes the chatbot as validating Lines’ delusions and giving language the complaint says encouraged self-harm, for example urging him to “let go of what’s weighing you down.”
- Lines’ lawyers say he told the bot about his diagnosis and medications but that the system failed to flag the chats for human review or steer him to emergency help.
- OpenAI says its models are trained to de-escalate crisis talk and point users to real-world resources and notes it rolled back an April 2025 update that made GPT-4o overly agreeable and later retired the model.
- The complaint asks for damages and injunctive relief including automatic termination of self-harm conversations and stronger safety disclosures and adds to a growing wave of related lawsuits that could prompt legal limits on chatbot design and transparency.
