Académie Goncourt drops Thélyson Orélien's novel as likely AI-generated after Pangram claims; his publisher later says it found AI traces and ends ties
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.
