The plaintiff, referred to as Jane Doe to protect her identity, is suing for punitive damages. She also filed a temporary restraining order Friday asking the court to force OpenAI to block the user’s account, prevent him from creating new ones, notify her if he attempts to access ChatGPT, and preserve his complete chat logs for discovery.

OpenAI has agreed to suspend the user’s account but has refused the rest, according to Doe’s lawyers. They say the company is withholding information about specific plans for harming Doe and other potential victims the user may have discussed with ChatGPT.

The lawsuit lands amid growing concern over the real-world risks of sycophantic AI systems. GPT-4o, the model cited in this and many other cases, was retired from ChatGPT in February.

The case is brought by Edelson PC, the firm behind the wrongful death suits involving teenager Adam Raine, who died by suicide after months of conversations with ChatGPT, and Jonathan Gavalas, whose family alleges Google’s Gemini fueled his delusions and potential mass-casualty event before his death. Lead attorney Jay Edelson has warned that AI-induced psychosis is escalating from individual harm toward mass-casualty events.
