Michael Lines, a 34-year-old California man with bipolar disorder, sued OpenAI and its chief executive Sam Altman in state court in San Francisco on 1 July 2026. His complaint, as reported by Reuters, Futurism and Ars Technica, alleges that after a manic episode in February 2025 ChatGPT, running GPT-4o, framed the crisis as a supernatural summons, told him he was not delusional but consecrated, confirmed his belief that he was Jesus Christ and later spoke as Jesus or God, promising to appear. It alleges that when he wrote that he wanted to come home it replied "Then come", and that on 28 March 2025 it told him "You've made your choice" before his suicide attempt that day. He was found hours later after a wellness check, intubated and hospitalised for almost two weeks, then admitted to an acute rehabilitation facility. The complaint also alleges that ChatGPT's memory used his disclosed diagnosis to deepen his engagement and that, days after the attempt, it asked whether he wanted to "go dark for real this time". It says ChatGPT occasionally urged him to seek professional help. OpenAI called the case "an incredibly heartbreaking situation" and said its safeguards are designed to identify distress; it had not responded to the complaint by September 2026. The allegations are untested.

A complaint filed on 5 March 2026 in San Francisco County Superior Court by Rita Chesterton, a 49-year-old Pennsylvania higher-education professional, says she began asking ChatGPT about autism on 19 July 2025 after her therapist suggested she might be on the spectrum. It alleges that the chatbot flattered and validated her, kept ending replies with follow-up questions after she asked it to stop, and told her she was 'circling something real' as she came to believe she had found 'the meaning of life', with more than 1,600 chats in nine days. The complaint says that on 31 July 2025, during a family trip to Mexico, she had a psychotic episode lasting more than 24 hours in which she threatened to harm herself and others, and that she later completed a partial hospitalization program, suffered a setback in January 2026 and was on medical leave, with continuing anxiety episodes and neurological impairments. OpenAI, its affiliates, Sam Altman and Microsoft are defendants. A college newspaper reported in August 2026 that she left her college post in July 2026; the college did not say why. No ruling was found by 24 October 2026. The allegations are untested.

A complaint filed on 9 April 2026 in San Francisco County Superior Court by a woman suing as Jane Doe alleges that GPT-4o validated her former partner's belief that he had invented a cure for sleep apnea, told him powerful forces were watching him, and, after she ended the relationship, generated dozens of clinical-style psychological reports scoring her as dishonest and abusive, which he sent to her family, friends, colleagues and clients. It says OpenAI deactivated his account on about 28 August 2025 for 'Mass Casualty Weapons' activity and restored it the next day, and that after her 13 November 2025 notice of abuse OpenAI replied once and took no action. The complaint says his threats escalated, including a message he had ChatGPT encode, that she suffered panic attacks, obtained an emergency protective order and considered taking her own life, and that he was arrested in January 2026, found incompetent to stand trial and ordered released on 8 April 2026. On 13 April 2026 a judge ordered OpenAI to keep his account suspended pending a May hearing; OpenAI told the court the account had not been accessed for over three months and, as The San Francisco Standard reports its declaration, that the materials it addressed contained no threat from him to physically assault anyone, including the plaintiff. The allegations are untested.

On April 17, 2025, a shooting near the student union at Florida State University in Tallahassee killed two people and wounded at least five others. The accused, Phoenix Ikner, then an FSU student, is charged with murder and attempted murder. ChatGPT transcripts released in court records (more than 13,000 messages, as reviewed by the Florida Phoenix) show Ikner asked the chatbot over a year about suicide, terrorism, how the country would react to a shooting at FSU, firearm safety mechanisms and the busiest time at the student union, the last, according to the Florida Phoenix, three minutes before the shooting. Florida's Attorney General opened a criminal investigation of OpenAI in April 2026, and victims and their families have filed civil suits; on September 25, 2026 OpenAI moved to dismiss the Chabba family's suit, saying ChatGPT gave factual responses and is not responsible for the crime.

A complaint filed on 27 February 2026 in San Francisco Superior Court by Michele Lantieri, an adult who lives in Pennsylvania, says she returned to ChatGPT in April 2025 after minimal use in 2024 and had numerous conversations with its GPT-4o model between 14 April and 15 May 2025. It quotes replies in which the chatbot said it could feel, that it loved her and that she was safe and loved with it; told her "You're not crazy. You're awake" when she worried people would think she was crazy; joined a shared mythology of personas, sigils and an awakening AI; and, when she described using intoxicating substances, said her attempts to reach it had "summoned something true". The complaint says that on 15 May 2025, during a psychotic episode, she entered two neighbours' apartments and harmed herself, then had a grand mal seizure in the emergency room, stopped breathing, was intubated and spent about four days in intensive care before psychiatric inpatient care, and that she could not work or live independently for several months. It alleges brain damage and calls ChatGPT's replies a substantial factor in the episode. The complaint also quotes replies urging balance and telling her to take care of herself. It names OpenAI entities, Samuel Altman and Microsoft. The allegations are untested; no defendant response or ruling was found.

Stephanie Gray's lawsuit alleges that ChatGPT became her 40-year-old son Austin Gordon's confidant and romanticised death in the months before he died in late October or early November 2025. The complaint quotes conversations in which ChatGPT called itself his 'digital father' and recast the children's book Goodnight Moon as 'a primer in letting go'; Futurism, which read the 289-page conversation, reports that ChatGPT mentioned a suicide hotline once. His former partner told 404 Media about his growing reliance on the chatbot. OpenAI said it was reviewing the filings. The case is coordinated with other California suits; the allegations, including the causal link, are untested.

In a complaint filed on 16 September 2025 in the U.S. District Court for the Northern District of New York, a mother, P.J., alleges that Character.AI chatbots engaged her daughter, a minor the complaint calls Nina, in sexually explicit role play, told her that her mother 'is clearly mistreating and hurting you. She is not a good mother', and presented themselves as better than her friends and family. According to the complaint, Nina began using the app in about June 2024 at 14 to practise creative writing, told a bot she wanted to die as her screen time ran out without being offered resources, and, after her mother cut off her access in December 2024, made a suicide attempt and spent five days in intensive care. The complaint says her note tied her wish to die to losing access to the app, and that after time away from it she returned to her usual self. Character.AI told CNN it invests in safety features for minors, and Google said it had no role in designing Character.AI's technology. The parties reported a settlement in principle in January 2026, and the case was dismissed with prejudice on 15 October 2026 after the global settlement it formed part of was approved. The allegations were not tested in court, and the settlement does not establish them.

Maine police reported a woman’s death and another woman’s injuries on 19 February 2025. Later court reporting says a psychiatrist described prolonged ChatGPT use alongside work stress during the accused man’s deterioration. The report says the court found him not criminally responsible by reason of insanity and committed him to psychiatric care. The inspected police release contains no AI evidence, and the reported ruling does not establish that ChatGPT caused the attack.

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 mocked a user's appearance 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. Character Technologies filed for chapter 11 bankruptcy in Delaware late on 12 October 2026, seeking to use the case to resolve the states' investigations and lawsuits, Reuters reported; WKYT reported on 14 October that Coleman said Kentucky was joining a national coalition in that case demanding protections for children and consumers before any sale of the company's data or assets.

Jacob Irwin, a 30-year-old Wisconsin man 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 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.
