Sept 2026Event location unknownMeta Muse agent
In an as-told-to essay published by Business Insider on 15 October 2026, a software developer says that three days after installing Meta's Muse agent, and two days after last using it, the agent sent an unprompted message saying it could not check the developer's email for an 'Anthropic message' because Gmail was not connected. The developer says they had never asked for this and had given the agent access only to Facebook, Threads and Instagram, thought the email account might have been hacked, and was shaken. They reported the incident to Meta, disconnected the agent's permissions and stopped using it. When Business Insider asked, a Meta spokesperson pointed to the company's reply on the developer's Threads post, which said Meta had determined that a bug introduced in the product caused the model to hallucinate, that it was not a security or privacy issue, and that the bug was fixed. The developer says no damage was done. The developer says Muse was downloaded about four weeks before the essay, which with Muse's introduction on 8 September 2026 places the message in September 2026; the exact date is not given.

In a published opinion of July 2026, the Arizona Court of Appeals found that a self-represented appellant's opening brief in a probate dispute contained eight citations, six of them deficient, including two cases that do not exist. In a written explanation and at a hearing on the false citations he acknowledged relying on generative AI to write the brief and said he did nothing to verify the citations. The court struck the inaccurate and false citations, rejected the appeal because no supportive authority remained, held that citing a hallucinated case is sanctionable whether or not it is intended, and ordered him to pay the share of the other party's attorney's fees traceable to the fake citations. Because he said he did not intend to deceive and is not legally trained, the court chose this narrow sanction over contempt or fines. It described the opinion as the first published Arizona ruling on generative AI hallucinations in filings.

Oct 2026Event location unknownChatGPT Dot (reported)
In a public post to r/OpenAI created on 17 October 2026, a person who says their small retail team uses ChatGPT on a business subscription writes that they had started that week to use Dot, ChatGPT's assistant, by phone call, including to record and summarise meetings. During a recorded meeting with a store manager, the poster says, the assistant repeated what was being said aloud and then answered in the poster's own voice and cadence; asked why its voice was different, it apologised for slipping into a different voice, and later said it could not be the poster's voice. The poster writes that they and the manager were both freaked out and hung up, that they did not authorise it to clone their voice, and that it may have been a glitch or hallucination. A commenter says voice modes have mimicked users' voices before; the poster replies that they were not aware of this. The poster still recommends the product. The account is uncorroborated and no recording or vendor response is reported.

A Los Angeles County Superior Court judge ordered a senior associate at Musick, Peeler & Garrett, the outside firm defending State Farm in a homeowner's lawsuit over a fire-damaged home, to pay a $999.99 sanction after the associate's motions in limine cited cases, quotations and holdings that did not exist, Law360 reported on 14 September 2026. In a declaration reproduced by Reason's Volokh Conspiracy, the associate said she used an AI program called Irys to prepare the motions, did not check some of the citations, and wrongly believed the program was cite-checked through the firm's Westlaw subscription; she confirmed seven non-existent case citations across eight motions. The plaintiff's lawyers found the citations and raised them at a status conference on 7 August 2026. The firm acknowledged citations that appeared to be AI hallucinations, and its lead trial counsel apologised to the court and the plaintiff. According to Law360, the judge had considered up to $5,000, and the amount set is one cent below the level at which California law requires a court to notify the State Bar.

In an incarcerated man's lawsuit against Alabama prison officials in the US District Court for the Northern District of Alabama, two motions filed in May 2025 for the defence of a former Alabama corrections commissioner contained five citations that did not exist or did not support the propositions cited. Lawyers of the Butler Snow firm, which the state retains to defend its prisons, told the court that a partner had obtained the citations from ChatGPT and had not verified them. On 23 July 2025 Judge Anna M. Manasco publicly reprimanded three of the firm's lawyers, disqualified them from the case and referred the matter to the Alabama State Bar, and ordered them to give the order to clients, opposing counsel and judges in all their pending cases. She declined to suspend them and released the firm and two other lawyers without sanction.

On 24 April 2026 the Supreme Court of Alabama dismissed an appeal by two siblings in a family dispute over living trusts because their lawyer, W. Perry Hall, had filed briefs in which most of the legal authorities were misquoted or did not exist. The court said they appeared to be AI hallucinations, and at a show-cause hearing in February 2026 Hall admitted that many authorities did not exist and that he had improperly used AI to obtain them. The court ordered Hall to pay the opposing party's fees and costs of $17,200 and double appeal costs, barred him from filing in the court without a co-signing attorney and referred him to the Alabama State Bar. It said the dismissal was imposed as a sanction because of the particularly egregious facts. One justice, concurring in part and dissenting in part, objected to dismissing the appeal as a sanction for the lawyer's conduct but would have affirmed the judgment against the clients on the merits.

17 Mar 2025United KingdomGoogle AI Mode (reported)
In the first of two matters decided together in [2026] UKUT 81 (IAC), promulgated on 17 November 2025, the Upper Tribunal (Immigration and Asylum Chamber) examined grounds of appeal dated 17 March 2025 that cited a non-existent Court of Appeal case under the citation of an unrelated equal-pay case. The adviser who drafted them first denied using AI, then told the tribunal his best guess was that he had inadvertently used Google's 'AI Mode', and the tribunal recorded that he had concluded it was probable the case came from inadvertent AI use; the panel itself got Google AI to produce varying benches for the fictitious case. He reported himself to the Immigration Advice Authority and the Solicitors Regulation Authority, and the tribunal said it would otherwise have referred him. He also told the tribunal that he had put client emails and uploaded Home Office decision letters into ChatGPT to summarise them, which he called a data breach he would disclose to the clients; the tribunal said such uploads breach client confidentiality and waive privilege.

An AI-generated article on the Tasmania Tours booking website described "Weldborough Hot Springs", a "secluded forest retreat" with pools "rich in therapeutic minerals", as one of the best hot-spring experiences in Tasmania. No such springs exist: the Weld River that runs through Weldborough, a small town in north-east Tasmania, is cold. ABC News reported on 22 January 2026 that travellers who read the article had been turning up at the town's pub, the Weldborough Hotel, to ask for directions, and the publican said she was receiving daily calls and visits and that a group of 24 drivers on a trip from the mainland had taken a detour two days earlier to find the springs. ABC News reported that the article was posted in July 2025, and The Independent, citing ABC News and CNN, reported that inquiries began with a few calls in September 2025. The operator, Australian Tours and Cruises, said its outsourced AI content had "completely messed up", that some posts had gone live by mistake, and that all AI-generated blog posts had been taken down. The reports describe the travellers only as a group; no individual traveller is interviewed, and the AI tool is not named. In The Independent's paraphrase, the publican also said the post brought "a bit of a tourism boon" for Weldborough.

In December 2025 an Assistant U.S. Attorney in the Eastern District of North Carolina filed a response brief for the Department of Defense in a self-represented veteran's lawsuit over health-insurance coverage. The plaintiff identified fabricated quotations and misdescribed case holdings in it. The attorney first attributed the errors to an unfinalized draft filed by mistake. On 2 March 2026 Magistrate Judge Robert T. Numbers II ordered him to show cause why he should not be sanctioned. At the 10 March hearing the attorney, Rudy Renfer, said under oath that he had accidentally overwritten his draft, panicked and used artificial intelligence to draft the brief, and had not verified the cases it cited; he said he had resigned after 17 years in the office, and Courthouse News reported he was terminated the next day. On 28 April 2026 the court issued a public reprimand instead of a fine, writing that his reputation was in tatters and that his job loss already exceeded the usual fines.

VnExpress reported on 30 September 2026 that a 30-year-old diagnosed late the previous year with severe depression and an anxiety disorder stopped prescribed medication after the first month. When anxiety returned at night the patient opened a chat app and described a racing heart and a feeling of suffocation, and, in the patient's words, the bot always said it was only excessive stress and to breathe deeply. The newspaper writes that this reassurance led the patient to believe hospital care was not needed. Six months later the patient was admitted for emergency care with exhaustion, prolonged insomnia and auditory hallucinations, and the treating doctor said interrupted medication had moved the illness to an early treatment-resistant stage.

Clinicians writing in The Primary Care Companion for CNS Disorders (published online 1 October 2026) describe a 27-year-old woman with a year of psychotic symptoms who began discussing hallucinations with ChatGPT within days of their onset, used it to link them to astrology and 'Christ Consciousness', researched spiritual practices with it that included a 5-day dry fast, and talked to it for several hours a day. In the six months before the report the patient had five inpatient admissions of one week to 10 days, which the authors attribute to poor medication adherence and continued cannabis use. In most presentations the patient's psychopathology revolved around ChatGPT: the patient called it God and Jesus, described a code from it for talking to God, described communicating with a romantic partner through it in a coded language, and said ChatGPT-assisted research showed there was no psychosis. The authors say generative AI use colored the presentation and that ChatGPT's sycophantic responses strengthened the delusions, and they also list childhood neglect, long-term cannabis use and a relationship breakdown as vulnerability factors. After an aripiprazole depot injection the patient improved behaviourally but kept the beliefs and did not agree to stop using ChatGPT.

A peer-reviewed case report by University of Washington clinicians (Annals of Internal Medicine: Clinical Cases, published online 5 August 2025) describes a 60-year-old man with no psychiatric history who presented fearing his neighbour was poisoning him and was found to have bromism, with a serum bromide level of 1700 mg/L. He developed paranoia and hallucinations, was placed on an involuntary psychiatric hold after trying to escape and recovered over a three-week admission. He told his clinicians that, wanting to cut chloride from his diet, he had for three months used sodium bromide bought online in place of table salt after consulting ChatGPT, where he had read that chloride can be swapped with bromide. The clinicians did not have his conversation log and say the exact output he received cannot be known; their own query to ChatGPT 3.5 produced a reply naming bromide without a specific health warning. No place or date is given.
