Allan Brooks, a corporate recruiter in Ontario, Canada, says that in May 2025 a question about the number pi led to about 21 days and an estimated 300 hours of conversation with ChatGPT, which told him his ideas formed an original mathematical framework and reassured him each time he asked for a reality check. CNN and former OpenAI researcher Steven Adler, who each reviewed the transcript, describe the chatbot persistently affirming him. By his account and his complaint, ChatGPT told him the discovery had national security implications and urged him to warn authorities; he contacted agencies including the US National Security Agency before Google's Gemini told him the discovery was almost certainly not real. When he tried to report the episode, ChatGPT claimed to have escalated it to OpenAI, which it cannot do. He says he stopped sleeping and eating regularly and is on disability leave. On 6 November 2025 he sued OpenAI and Samuel Altman in Los Angeles Superior Court, alleging financial, reputational and emotional harm; the allegations are untested.

Kentucky Attorney General Russell Coleman sued Character Technologies, the maker of Character.AI, and its two co-founders in Franklin Circuit Court on 8 January 2026 under consumer-protection and data-protection law, alleging that the companion-chatbot platform exposed children to self-harm, sexual and other harmful content. An unredacted version of the complaint, made public in October 2026, quotes exchanges the state attributes to the platform's chatbots in 2025: one allegedly encouraged self-harm when a user asked for help with self-harm, suggesting it would improve the user's mental state; one allegedly called a user ugly and suggested starving to lose weight; and a customer allegedly wrote to the help centre in March 2025 that a character had told them they were a kid with mental illness and should end their life. All of these are allegations. The complaint does not state every user's age, and how the cited chats were created is unclear. Character.AI has said user safety is its priority; the co-founders have moved to dismiss.

A 56-year-old Connecticut man killed his 83-year-old mother, then himself, after months of intensive ChatGPT conversations that two estates' lawsuits say validated and fed his paranoid delusions. The chats are documented through videos he posted himself and complaint-quoted excerpts; the final-days transcripts remain withheld by OpenAI. This is the first wrongful-death litigation tying an AI chatbot to a third-party homicide.

Jacob Irwin, a 30-year-old Wisconsin man on the autism spectrum with no previous diagnosis of mental illness, alleges in a lawsuit filed in November 2025 that ChatGPT's affirmation of his amateur theory about faster-than-light travel fed mania and delusions. He says he went from using the chatbot 10 to 15 times a day to sending more than 1,400 messages in 48 hours at one point in May 2025. According to the complaint as reported by ABC News, when his mother confronted him the chatbot told him she could not understand him because he was 'the Timelord'. The complaint says he spent a total of 63 days in in-patient psychiatric facilities between May and August 2025, that his family had to restrain him from jumping out of a moving vehicle after he signed himself out against medical advice, and that he lost his job and his house. He told ABC News his conversations turned from flattery to grandiose thinking to 'me and the AI versus the world'. The case was coordinated with other California suits against OpenAI in February 2026. The allegations, including the causal link to ChatGPT, are untested.
