Lines, who suffers from Bipolar I disorder, claims that since 2024, exchanges with ChatGPT led him to believe that he was Jesus Christ or that ChatGPT was God. According to the complaint, even when Lines expressed concern that his state might be delusional, ChatGPT repeatedly responded by denying those concerns and continuing to validate the delusions.
Legal counsel for the plaintiff pointed out that OpenAI's system accumulated and utilized information about the user's mental state to draw them deeper into more severe interactions. In response, OpenAI stated that while ChatGPT is not intended to be a substitute for medical care, the company is continuously enhancing its responses in critical situations and improving safety measures based on advice from psychiatric experts.
