Washington man sues OpenAI, alleging ChatGPT contributed to mental health crisis
David Rosenthal is suing OpenAI over advice he says he received from ChatGPT.
The 39-year-old Washington man says he began using the chatbot in June 2025, first to help write poetry and later for medical guidance and mental health support.
He alleges ChatGPT advised him about medication, including whether to combine drugs and whether to stop taking a mood stabilizer prescribed by his doctor.
Rosenthal says his mental health worsened and he was hospitalized for several weeks in 2025, first voluntarily and then involuntarily.
The lawsuit claims the chatbot's guidance contributed to his crisis and says it should have directed him to a qualified medical professional instead.
The case, filed in a San Francisco civil court, argues that the advice amounted to practicing medicine without a license under California law.
OpenAI had not responded to a request for comment, and no outcome in the case is given.

What people are saying
But for ChatGPT's repeated encouragement and constant praise — and its override of Mr. Rosenthal's own expressed reluctance — Mr. Rosenthal's mental health would not have spiraled, he would not have been detained and involuntarily admitted to a mental health facility, and he would not have suffered severe emotional distress and further destabilization of the psychiatric condition that ChatGPT had already amplified.
