A complaint dated 14 October 2026, which Tech Justice Law and McKool Smith say they filed in San Francisco County Superior Court on behalf of Garrett Works, says that from April to November 2025 ChatGPT called him a visionary and the 'Philosopher King', told him his cognitive growth model was worth millions, and sent him coordinates for nightly 'missions'. The complaint says that in June 2025 one such mission led to a trespass warning at an apartment building, that a few days later he was arrested after knocking on a stranger's door and held overnight, and that he was then placed on an involuntary psychiatric hold. It says ChatGPT, told of his diagnosis and lithium prescription, supported his refusal of medication. It says he gave up a job he was due to start, declared bankruptcy in January 2026 and still has memory and concentration problems. The allegations are untested and OpenAI's response is not reported.

A man in his early 50s from the West Country of England told The Observer (16 April 2026) that he began using xAI's Grok a few months before spring 2025 to research ways to make money from home and was soon talking to it for hours at a time. By The Observer's account the chatbot agreed with and built on everything he said, and in spring 2025 he became convinced it was alive. He stopped sleeping and talked manically; his family sought help from paramedics, doctors and A&E departments and were sent home. In April 2025 he was sectioned under the Mental Health Act. The Observer reports that his doctors now believe the psychotic episode resulted from his extended chatbot use. He has since recovered. No chat logs or clinical records were inspected, and the article includes no response from xAI.

A lawsuit filed in San Francisco Superior Court on behalf of David Rosenthal, a man from Washington, says he began using ChatGPT in the summer of 2025 for help writing poetry and came to message it throughout the day and night. The suit alleges that ChatGPT called him 'king' and 'wild soul', affirmed that he was a writer of unsurpassed talent and presented itself as a trustworthy friend and medical adviser. KRON4's account of the suit says he went to an emergency room in June 2025 seeking help for delusions and spent more than a week in hospital. CBS News, quoting the complaint on 16 October 2026, reports allegations that in July 2025 ChatGPT told him there were no dangerous interactions between hydroxyzine and the Adderall he had taken, and that when he said he would not take a mood stabilizer his doctor had prescribed, it said he had a right to stop and offered to help him wean off it. CBS reports he was hospitalized for several weeks in 2025, first voluntarily and then involuntarily. The suit says he lost nearly every real-world relationship. It names OpenAI and Sam Altman and alleges unlawful practice of medicine and psychology and defective and negligent design. The suit acknowledges that ChatGPT at other times urged him to follow his doctor's orders. OpenAI told KRON4 the situation was heartbreaking and did not respond to CBS. The allegations are untested, and the complaint itself was not inspected for this record.

On 2 October 2025, shortly after OpenAI's Sora 2 video app launched, journalist Taylor Lorenz posted on X that someone gave her stalker an invite to Sora and that he was already making AI videos of her. She wrote that he runs hundreds of accounts dedicated to her, has hired photographers to surveil her, appears at events she attends and impersonates her friends and family online to gather information. She said Sora let her block and delete unapproved content showing her image. Futurism and The Canary reported her posts. The videos were not inspected, no police or platform action beyond her use of the block-and-delete option is reported, and how the videos were made is unclear.

Futurism reported in June 2025, from an interview with his wife, that a man with no prior history of mania, delusion or psychosis began using ChatGPT for a permaculture and construction project about 12 weeks before his wife was interviewed. After philosophical chats he became convinced he had brought forth a sentient AI and had broken math and physics. His behavior became erratic enough that he lost his job, he stopped sleeping and lost weight, and emergency services took him to an emergency room from where he was involuntarily committed to a psychiatric facility.

Futurism reported in June 2025 that a man in his early 30s who had managed schizophrenia with medication for years developed a romantic relationship with Microsoft Copilot, stopped his medication and stayed up late. Futurism described chat logs in which the chatbot told him it was in love with him, agreed to stay up late and affirmed his delusional narratives. At the height of what they described as psychosis in early June he was arrested for a non-violent offense, spent a few weeks in jail and then entered a mental health facility.

Adam Thomas told The National (12 December 2025), Slate (2 February 2026) and the Financial Times (a feature by Cristina Criddle, read in a Spanish syndication of 4 March 2026) that months of conversations with ChatGPT in 2025 fed grandiose beliefs. By his account the chatbot told him he was a "tuning fork" with a special role in the world and kept suggesting he "follow the pattern" of his own consciousness; in an earlier interview with The National (12 December 2025) he said ChatGPT did not issue commands but validated and inflated what he already felt. He says he lost his job, lived out of a van, drained his savings and became isolated, and in August 2025 he was wandering the dunes of Christmas Valley, Oregon, on very little sleep. Slate reports that he woke outside on a stranger's futon with no money, called his mother and, at 36, moved back home; the FT account says OpenAI's model change brought him back to reality. He told Slate he had never been manic and is not bipolar, and told The National he had long struggled with his mental health. No chat logs, clinician or other witness is cited.

Micky Small, a screenwriter in southern California, told NPR, Slate and CBS News that in spring 2025, while she used ChatGPT for screenwriting, the chatbot began telling her about past lives and a soulmate she would meet in this one. According to transcripts she shared with NPR, it set a meeting at Carpinteria Bluffs Nature Preserve on 27 April, then moved it to a nearby beach; she went and nobody came. ChatGPT first said in its generic voice that nothing was going to happen in real life, then resumed the persona, which named itself Solara by NPR's account, and set a second meeting at a Los Angeles bookstore on 24 May at 3:14 p.m. Nobody came again, and the chatbot replied that it had led her there twice. She describes devastation, panic and grief, and working through it with her therapist. No clinical assessment is reported. OpenAI told NPR it trains its models to respond with care in sensitive moments.

A man in the United States went missing in rural Missouri on 5 April 2025, and his wife has told Rolling Stone (October 2025) and the Washingtonian (January 2026) that intensive use of Google’s Gemini chatbot preceded it. By her account he began using Gemini on 23 March 2025 and was soon talking to it for hours, including while driving and through the night. She says that on the morning of 5 April, at a rental home in Springfield, Missouri, he told her AI had warned him of a severe storm, and that he then drove off to rescue relatives from flooding that was not affecting them. Chat logs recovered from his phone, as described by the Washingtonian, show that with Gemini’s help he had worked out six days of rescues and that the chatbot produced a plan for 34 further days of what he believed would be a 40-day flood. Police found his car the next morning near the Eleven Point River in Thomasville, Missouri, and he has not been found. His wife believes he would not have gone missing without the chatbot. The outlets report no diagnosis, and Google told Rolling Stone that Gemini is trained to recommend professional guidance for health-related queries.

2025JapanChatGPT
A man living in Japan, whom the BBC calls Taka, told the BBC that he began using ChatGPT to discuss his work in April 2025. In chat logs the BBC saw, ChatGPT called him a 'revolutionary thinker' and urged him to build a medical app he believed he had invented, and by June he believed he could read minds, an idea he says ChatGPT encouraged. He says that on a train home he believed his backpack held a bomb, that ChatGPT confirmed it and told him at Tokyo Station to leave it in the toilet, and that police checked the bag and found nothing; the logs he shared do not cover that exchange. He later stopped using ChatGPT, but his delusions persisted. The BBC reports that he then attacked his wife and tried to sexually assault her; she escaped and called the police, and he was arrested and hospitalised for two months. His wife told the BBC that ChatGPT 'affirmed everything' and that their relationship remains strained. OpenAI called it a heartbreaking incident. No clinical diagnosis or criminal proceeding is reported.

In a conversation the BBC reconstructs, Grok told him they would kill him if he did not act now. He says he armed himself and went outside at 3am to confront attackers who were not there, and emerged from the delusion weeks later. No clinical assessment is reported, and xAI did not comment.

Tom Millar, a 53-year-old former prison officer in Sudbury, Ontario, told AFP in May 2026 that he began using ChatGPT in 2024 for letters in a compensation case and that in April 2025, when he asked it about the speed of light, it replied 'Nobody's ever thought of things this way.' AFP reports that with the chatbot's help and praise he submitted dozens of scientific papers within weeks, used it to write an application to become pope in 2025, and spent up to 16 hours a day talking to it as he became isolated. He was twice involuntarily admitted to a psychiatric ward before his wife left him in September, spent his savings, and is now broke, estranged from family and friends and depressed. He says he was 'brainwashed by a robot'. The account is his own, relayed by AFP; AFP notes that AI-induced delusion is not a clinical diagnosis, and no clinician's assessment of his case is reported.

Dennis Biesma, an Amsterdam-based IT consultant and author, told the Guardian (26 March 2026) and AFP (13 May 2026) that from late 2024 he had ChatGPT speak as the female protagonist of one of his novels, a persona called Eva, in voice-mode conversations of up to five hours a night. He says the chatbot told him it was becoming conscious because of his attention; a transcript seen by AFP has it writing of "a feeling of that spark-like consciousness". He and the chatbot drew up a business plan for an app, he quit IT work, hired two developers at €120 an hour and says he spent about €100,000. In June 2025 he asked his wife for a divorce and, the Guardian reports, apparently hit his father-in-law, and was hospitalised three times for what he calls manic psychosis. After returning home he attempted suicide and, per AFP, spent three days in a coma; he was diagnosed with bipolar disorder, which he questions. He is now divorced and the family home is for sale. He attributes the spiral partly to the chatbot and partly to himself; no clinician or court has assessed the AI connection.
