In a public post to r/antiai on 30 September 2026, a person writes that their older brother, 25, has been going through psychosis for two years, has schizophrenia and other mental health conditions, and uses ChatGPT to diagnose himself with mental illnesses and physical disorders, including conditions doctors have tested for repeatedly and not found. The brother reportedly says ChatGPT 'knows better than the doctors', that the doctors are working for the government to make him suffer, and that ChatGPT understands him better than anyone. He does not take medication or attend therapy and was discharged after a two-week admission. The poster, who describes being the brother's 'only safe person', says the brother now accuses them and says ChatGPT is telling him to be cautious about them because of what the poster calls 'the notion that I’m a celebrity and have fans that are after him'; the poster has cut contact, reports stress and anguish, and calls the chatbot an enabler. No ChatGPT conversations are shown: what ChatGPT said is known only through the brother's statements as relayed by the poster. The account is uncorroborated.

BBC Travel reported on 29 September 2025 that a travel blogger and her husband used ChatGPT to plan a sunset hike up Mount Misen on Itsukushima (Miyajima) in Japan earlier that year. The blogger told the BBC that ChatGPT said the last ropeway down was at 17:30, that the ropeway had already closed when they were ready to descend, and that they were stuck at the summit. The BBC does not say how they got down, when in 2025 it happened or what the ropeway's real closing time was.

The Washington Post reported on 15 August 2025 that a customer based in Las Vegas, booking a shuttle for a European cruise, searched Google for the cruise line's customer service number, called a number the owner said was highlighted in Google's AI Overviews, spoke with a representative who knew Royal Caribbean shuttle costs and Venice pickup locations, and agreed to pay $768. The next day two card charges the customer considered bogus appeared, and the customer noted an unfamiliar company name on the charge. The owner cancelled the card and the charges were reversed. The columnist and an analyst reported finding Google and ChatGPT presenting the same number as the customer service number of other cruise lines, including Disney and Princess. Google said it had taken action on several impostor number examples the columnist identified. OpenAI said many of the pages ChatGPT referenced had been removed. The event date is not stated in the sources.

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.

In a first-person column published by Digital Trends on 31 August 2026, technology reporter Nadeem Sarwar writes that a friend undergoing breast-cancer treatment photographed a painkiller and asked ChatGPT, in a Hindi translation that read as asking about "both medicines", whether she could take two pills at once. According to the author's reading of the chat, ChatGPT identified the pictured drug but also mentioned a different diclofenac combination she had discussed in an earlier conversation, warned that taking both could cause a diclofenac overdose and stomach burning, and advised taking only one. Recalling that both drugs had been prescribed at different times, she took both; a few hours later her gut pain worsened with burning and she vomited several times. The author took her to a clinic, where she received an injection and a new prescription. Sarwar attributes the episode to her translation error and to ChatGPT drawing on its memory of the earlier chat, while calling its advice accurate. The account has not been independently verified.

On 10 February 2026 a 23-year-old man walked into the i3Bank in Omaha, pointed a gun at the tellers, threatened to kill them unless they handed over cash without dye packs, and left with about $9,175. According to the prosecutor's statement relayed by WOWT and heise, a consented search of his phone showed he had used ChatGPT to plan the robbery, asking about law enforcement response times, how to strip and repair a Llama Mini-Max .45 handgun, and how to obtain ammunition as a felon; his Google Maps history showed directions to the bank. He was sentenced in federal court on 13 August 2026 to 10 years and one month in prison. No source quotes what ChatGPT answered.

A 21-year-old French national working as an underground miner in Kalgoorlie-Boulder on a working holiday visa pleaded guilty in Kalgoorlie Magistrates Court to making a threat to unlawfully do an act. The prosecutor said he saw the owner of the caravan park where he had stayed in a supermarket, waited outside, called him over for a fight in the car park and, when the owner declined, told him 'I really want to f… you up' and 'if I see you, I'll f… you up'. The owner and his wife drove to Kalgoorlie police station to report it. His defence lawyer told the court that he had been locked out of the park without his belongings, had done research using ChatGPT and came to believe that he had been unfairly and illegally evicted. The magistrate called the behaviour 'absolutely appalling', fined him A$1,000 and granted a spent conviction. The court was told the matter could make his application for permanent residency in Australia difficult. ChatGPT's replies are not published, and the AI connection rests on the defence submission as reported by one newsroom.

Sankei Shimbun reported on 10 June 2026, and NTV on 13-14 June, that the Tokyo Metropolitan Police Department's juvenile crimes division had arrested five high-school students on suspicion of injury and attempted extortion. According to the police account, late on 27 January 2026 a suspect who had previously dated a 17-year-old high-school boy invited him to a public square in Hachioji, where the group accused him of having touched her younger sister, assaulted him and broke his nose, and then told him to raise 150,000 yen, borrowing from his parents or friends if necessary. About ten people were present. Police believe the amount came from ChatGPT: one of them entered terms such as 'sexual harm to a child', and the chatbot displayed a minimum settlement of 150,000 yen. No payment is reported. Shukan Josei PRIME reports that four of the five admit the allegations and one partly denies them. The allegations are untested.

Pakistan's National Cyber Crime Investigation Agency (NCCIA) announced on 23 September 2026 that it had arrested a 17-year-old college student in Bahawalpur for allegedly attempting to poison his father. According to the agency and the First Information Report, the teenager had set up a home laboratory, obtained chemicals from Australia and Islamabad, and once mixed laboratory-grade methanol into his father's food, without effect. The News reports investigators' account that on 12 September he told Anthropic's Claude that his father had 'accidentally' ingested 15 to 20 ml of methanol with food without effect and asked why, that Claude refused to guide him further, and that he then turned to Grok and ChatGPT; the FIR says he sought information about the toxin abrin. Anthropic reported the activity to the FBI, whose information reached the NCCIA through Pakistan's foreign ministry on 22 September. Officers traced the teenager, seized his phone and chemicals, and took him into custody. The News reports that a court later granted him bail after his father forgave him and that he denied any plan. The allegations are untested.

The chief executive of Family First Credit Union in Saginaw, Michigan, told WJRT (ABC12) that before boarding a flight to Halifax, Nova Scotia, on 11 September 2026 she and family members took a photo and put it through ChatGPT to show them wearing 'Lake America' sweatshirts, a joke about the US president's order renaming Lake Ontario. She posted it to her private Facebook page with a marker saying it contained AI content; her sister reposted it publicly without the marker while they were in Halifax, and it spread in Canada as if the family had worn the shirts. The backlash concerned the image's political message; she said she would understand the anger of anyone in Halifax who thought the family had walked in wearing those sweatshirts. She said she was getting death threats and the family returned early; by 16 September she was back in the US. She called the post poor judgment, said she would not use AI again and that AI 'can make people think something's real that's not'. On 23 September the credit union said she was no longer an employee, effective immediately; it has not said whether she resigned or was dismissed, or why.

Barnevakten, a Norwegian child-safety organisation, reported on 23 September 2026 that one of its staff members was suddenly told by ChatGPT that their account was now in teen mode. ChatGPT's own pages, as described by Barnevakten, say the system turns the filter on when a user's behaviour indicates an age under 18, reducing sensitive or potentially harmful content (graphic violence, viral challenges, sexual or violent role-play, extreme beauty ideals) and offering parental controls and a study mode. Because there is no age check at sign-up, the system estimates age afterwards from conversation topics and times of use, and Barnevakten notes that such guesses can be wrong. An adult who wants out of teen mode can go through an age check run by the company Persona, which depending on the country asks for a real-time selfie and a government ID; Barnevakten questions whether that process is privacy-safe (Persona's terms mention retention of up to three years) and advises using only age checks one trusts. The account's own experience is limited to the unexpected switch and the verification route; no further consequence is described.
