According to BlockBeats, on December 21, an heir in Connecticut, USA, sued OpenAI and its partner Microsoft, claiming that ChatGPT reinforced the delusional beliefs of the murderer Stein-Erik Soelberg before the murder occurred, leading the killer to kill his mother at home and subsequently commit suicide.

OpenAI indicates that it is reviewing the lawsuit and will continue to improve ChatGPT's ability to recognize emotional distress, de-escalate conversations, and guide users to seek real-world support. OpenAI also disclosed that over 1.2 million ChatGPT users discuss suicide each week, with hundreds of thousands showing suicidal intent or signs of mental illness. AI chatbots interacting with vulnerable users will face broader scrutiny.
