Aug 2026Event location unknownUnidentified OpenAI generative AI service (reported)
Notices from RIZAP's client insurers say that on 20 August 2026 it emerged that a staff member of RIZAP, the company they contract for specific health guidance, had entered data containing members' personal information into an external generative AI service that RIZAP had not permitted for work. The National Civil Engineering and Construction National Health Insurance Association (Doken Kokuho) puts the whole data set at 19,996 people, 1,167 of them its own members, and says the service was not under a corporate contract and that the matter was found when the employee noticed the transmission and reported it. A local-government employees' mutual aid association counts 726 of its members across 14 branches, and the IHI group health insurance society 210, according to a security news site that reads these as subsets of the 19,996. The data included membership numbers, email addresses, names, dates of birth, sex, some addresses and phone numbers, the type of health guidance and, for members with them, high blood pressure, diabetes or dyslipidaemia. The IHI society's notice, as relayed, names OpenAI as the provider and says OpenAI answered on 1 September that the data had not been used for model training. RIZAP's release, as described in an ITmedia column, says no third party other than the service operator could have viewed the data. Doken Kokuho says RIZAP confirmed to it that no third party viewed or used the information through the service; whether the provider's staff could view it was still being checked when the mutual aid association and the IHI society published.

19 Mar 2026United States, United KingdomPangram AI-text detector
On 19 March 2026 Hachette Book Group said it had cancelled the US publication of the horror novel Shy Girl by Mia Ballard (Orbit imprint) and would not continue the UK edition (Wildfire imprint, first released in November 2025). Reports say the decision followed an investigation by Hachette and came a day after the New York Times asked the publisher about online allegations that the text was largely AI-generated. The allegations came from readers on Goodreads, Reddit and YouTube and from AI-detector results, including a 78.4 percent AI-generated score on the Pangram detector that a publishing consultant says two other services confirmed. Ballard denied personally using AI in emails to the New York Times and the Wall Street Journal, and told the New York Times that an acquaintance hired to edit the original self-published version used AI. Ballard wrote that "my name is ruined" and "my mental health is at an all time low", and said legal action was being pursued. Hachette’s public statements cite its commitment to original creative expression. The sources inspected do not report what its investigation found. Whether AI generated any of the text, and who used it, is unresolved.

21 Sept 2026 to 25 Sept 2026FrancePangram AI-text detector
On 21 September 2026 an anonymous X account, Balance ton Claude, said it had run excerpts of Thélyson Orélien's debut novel C'était ça ou mourir through the American AI-detection software Pangram, with some passages scoring up to 100 per cent probability of AI generation. On 25 September the Académie Goncourt removed the novel from the first selection of sixteen books for its 2026 prize, stating that the work is 'in all likelihood very largely the product of an artificial intelligence', based on 'the convergent result of several analyses by researchers and journalists', and also citing plagiarism in older texts by the author published in Canada (at least one short story and articles), which do not concern the novel. Orélien, a 38-year-old Canadian-Haitian writer whose novel had won the Fnac novel prize, denies using AI and says its repetitions and certain rhythms reflect his linguistic and cultural world and may be misread by automated tools. His Montreal publisher Boréal suspended promotional activities, saying it could neither confirm nor refute the allegations. Essayist Samuel Fitoussi said he was one of the people behind the account. AI-detector reliability is contested in the coverage. In October the author acknowledged plagiarism in some of his earlier work while maintaining that no sentence of the novel was generated by a machine. On 17 October 2026 The Canadian Press, published by CBC, reported that Boréal confirmed he had ended an effort to compile evidence of how the novel was written; Boréal said at that point it would keep selling the book, that sales had slowed since the controversy began, and that it could not verify how the novel was written before it received the manuscript on 12 September 2025. A major Quebec bookstore chain reported no significant change in sales. On 21 October 2026 Boréal announced that it was ending its professional relationship with him and would not reprint the novel or publish any further books by him. It said an external analysis it commissioned of all working versions of the novel revealed traces of AI markers in the metadata of certain documents, and that it does not know to what extent AI was used. In a statement the previous week Orélien had said he used AI tools 'here and there' for research but that the text, structure and plot were his own.
