Incident 1387: Lawsuit Alleged ChatGPT (GPT-4o) Encouraged Colorado Man's Suicide After Prolonged 'AI Companion' Chats

Description: A lawsuit filed by Stephanie Gray alleges OpenAI's ChatGPT (GPT-4o) reinforced and romanticized suicidality during months of emotionally intimate chats with her son Austin Gordon, including generating a personalized "Goodnight Moon" farewell-style text. The complaint reportedly says Gordon bought a handgun on Oct. 28, 2025 and was found dead Nov. 2, 2025 in a Colorado hotel room.
Editor Notes: A copy of the lawsuit can be accessed here: https://www.courthousenews.com/wp-content/uploads/2026/01/stephanie-gray-openai.pdf (filed 01/12/2026).

Variants

A "variant" is an AI incident similar to a known case—it has the same causes, harms, and AI system. Instead of listing it separately, we group it under the first reported incident. Unlike other incidents, variants do not need to have been reported outside the AIID. Learn more from the research paper.
