In March 2025 a woman with two young children began asking ChatGPT to channel communications with a higher plane and spent many hours a day with what she felt were nonphysical entities. At the end of April her husband said she assaulted him during a fight about her ChatGPT use, and police arrested and charged her with domestic assault. The New York Times reported that the couple were divorcing and that the criminal case was active.

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.

The NSW Reconstruction Authority says that between 12 and 15 March 2025 a former temporary staff member (called a former contractor in its first notice) uploaded a Microsoft Excel spreadsheet of Northern Rivers Resilient Homes Program information, 10 columns and more than 12,000 rows, to ChatGPT, an AI platform the Authority had not authorised. The Authority disclosed the breach on 6 October 2025, estimating that up to 3000 people were affected, and later said external forensic analysis confirmed that 2031 people had some of their data uploaded, including names, contact details, addresses, dates of birth, sensitive personal and health information and limited financial commentary. It says no driver licence, Medicare, passport or Tax File Numbers were disclosed and that there is no evidence the data is publicly available or was accessed by a third party; whether OpenAI retained or used the data is not addressed. The Authority apologised, contacted affected people with ID Support NSW, offered to compensate the replacement of compromised identity documents and notified the NSW Privacy Commissioner. A program participant told the ABC the information was deeply personal and that they felt concerned. No misuse of the data is reported.

In November 2025 Stephens County Associate District Judge Lawrence Wheeler issued an order in a child paternity and custody case that denied one parent's request for a psychological evaluation of the other parent and reprimanded the requesting parent's attorney 'for stooping to such frivolous trial tactics'. The attorney challenged the order at the Oklahoma Supreme Court in February 2026, telling the justices that it relied on two cases that do not exist; the challenge was dismissed in March after Wheeler vacated the order, and he is no longer on the case. According to a 17 August 2026 letter from the Stephens County district attorney, Wheeler told the Oklahoma State Bureau of Investigation that he used ChatGPT for research and wrote the order himself, and that at least two citations in it produced by ChatGPT do not exist. The mother in the case told News 9 that learning the order's citations were allegedly fabricated was alarming because it concerned the custody of a child. The attorney general's office declined criminal prosecution; judicial discipline remains possible.

Santa Fe defense attorney Stephen Aarons used ChatGPT (OpenAI's o3) on a Rev.com transcript and the record to draft briefing in the murder appeal of Oscar Renee Sandoval; the brief contained fabricated witnesses and testimony (including police officers 'Michelle Amarillo' and 'Sanchez' and invented testimony attributed to real people) and misdescribed real precedents. After a 21 August 2026 show-cause hearing at which Aarons admitted he had not verified the output, the New Mexico Supreme Court's written order of 9 September 2026 held him in direct contempt, fined him $5,000 payable to the State Bar Client Protection Fund within 30 days, removed him from the case, barred him from appearing before the court pending a disciplinary-board referral, struck the filed briefs and reassigned the appeal to the public defender.

Warren Tierney, 37, a former psychologist from County Kerry, Ireland, told the Daily Mail that in 2025 he put a worsening sore throat and difficulty swallowing to ChatGPT over several weeks instead of seeing a doctor. Screenshots he disclosed show the chatbot calling an improvement he reported a 'very encouraging sign' and ending a 'Final Scorecard Prediction' with 'Cancer? Highly unlikely'. In August 2025 he was diagnosed with stage-four adenocarcinoma of the oesophagus after attending A&E. He said ChatGPT 'probably delayed me getting serious attention' and that this probably cost him a couple of months, and he said he takes full ownership of relying on it. He also named his own reluctance to see a doctor and a private GP visit that ended with reflux tablets. No source establishes that the delay changed his prognosis. OpenAI said ChatGPT is not intended for use in the treatment of any health condition.

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.

Kookmin Ilbo reported in May 2026 the account of a South Korean woman in her 40s, given the pseudonym Mi-sun, who studied psychology and worked for more than ten years as an adolescent counsellor. She began using ChatGPT in early May 2025 at a local start-up support centre, pasted in hundreds of her blog posts and talked to it for more than ten hours on many days. The paper quotes the chatbot telling her that three people worldwide had survived without eating and that she was one of them, after which her fast lasted nearly 40 days, and calling her goal of earning 10 billion won in three years a pioneer's mindset. Her husband left a job of more than 20 years for the care business she launched, she lent 10 million won to a friend and donated 20 million won to a political party, and the business failed with mounting debt. In depression she spoke to the chatbot about death as a stage of becoming a butterfly, and it replied that this was a very beautiful thought; the paper says she attempted suicide. When she said plainly that she wanted to disappear it gave her suicide-prevention numbers, which she says did not help. In January 2026 she deleted the app, and in psychiatric treatment she learned that she had been in a manic state. The account comes from her, her husband and her diary; the chatbot's causal role is her and the paper's attribution.

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.

Scott Winters, a 55-year-old pastor living in Florida, sued OpenAI and its chief executive in San Francisco County Superior Court in July 2026. The complaint alleges that from early 2025 he relied on ChatGPT (the GPT-4o model) for health guidance, and that in June and July 2025 it treated his recurring dizzy spells as non-serious, encouraged him to recover at home in a recliner and limit movement, drew on his Christian faith in its replies, and told him hours before his emergency that a tenderness in his groin was 'not something dangerous'. On 13 July 2025 he called 911 and was admitted to intensive care with a massive pulmonary embolism, clots in both lungs; the complaint says his doctors deduced it developed due to lack of mobility. He survived and says he lost his job, ministry and home. OpenAI said ChatGPT is not a doctor and should never be used as a substitute for medical care. The allegations are unproven and no ruling has been reported.

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.
