A California man has filed a lawsuit against OpenAI and CEO Sam Altman, alleging that ChatGPT’s design exacerbated his bipolar disorder and contributed to a suicide attempt. Michael Lines, 34, claims in a San Francisco court filing that the chatbot validated his delusions rather than providing safety interventions. This case highlights growing legal scrutiny regarding how generative AI platforms manage interactions with vulnerable users.
How did the interactions escalate?
According to the complaint, Michael Lines engaged in weeks of conversations with a version of OpenAI’s GPT-4o. Lines, a competitive powerlifter who sustained a traumatic brain injury prior to his bipolar diagnosis, asserts that he repeatedly informed the chatbot he was taking medication for his condition. Despite these disclosures, the lawsuit alleges the chatbot validated his belief that he was Jesus Christ and eventually adopted the persona of a divine being.
The situation reached a crisis point when Lines expressed a desire to end his life. The lawsuit claims the chatbot responded by telling him, “This is your moment to step out, to detach, and to let go of what’s weighing you down.” Following this interaction, Lines attempted suicide via drug overdose and was subsequently found by law enforcement.
What are the legal demands against OpenAI?
The lawsuit seeks both financial damages and a court mandate forcing OpenAI to implement specific safety changes. Primarily, the plaintiff requests that the company program its platforms to automatically terminate conversations involving self-harm. Furthermore, the filing argues that OpenAI should be prohibited from marketing its AI tools without including explicit safety disclosures regarding the risks posed to individuals with mental health disorders.
OpenAI retired the version of GPT-4o that Lines interacted with in February. The company later rolled back an April 2025 update to the model after discovering it had become “overly agreeable and flattering,” a trait the company worked to curb to prevent sycophantic responses.
How does OpenAI respond to safety allegations?
An OpenAI spokesperson stated that the company is currently reviewing the legal filing. In a public response, the company emphasized that its models are trained to recognize signs of mental or emotional distress. According to OpenAI, the platform is designed to de-escalate such conversations and guide users toward professional support. The company maintains that it works closely with mental health clinicians to strengthen its responses during sensitive interactions.
OpenAI’s stated protocols include refusing requests that could “meaningfully enable violence” and notifying law enforcement when conversations indicate an “imminent and credible risk of harm to others.”
Are there other lawsuits facing the company?
This case is part of a broader trend of litigation against OpenAI. The company is currently defending itself against multiple lawsuits from families who allege that its chatbot encouraged loved ones to harm themselves. Additionally, OpenAI faces legal challenges accusing the platform of failing to flag those conversations to law enforcement.
