One sentence in the 528-page novel that won France’s most famous literary prize on November 3 was written entirely by ChatGPT, according to its author. Philippe Jaenada says he has told only the jury which one. Six weeks earlier, the same jury had dropped another novel from its list of contenders. It cited that author’s past plagiarism and said the book was “in all likelihood very largely the product of an artificial intelligence.”
The prize is the Prix Goncourt, and Jaenada, 62, won it on the first ballot. The jury, called the Académie Goncourt, voted six to three for him over Sylvain Prudhomme, the academy announced. His novel is “L’Inconnue du quai de Javel” (“The Unknown Woman of the Quai de Javel”), published by Flammarion. The next morning, he told France Inter, a French public radio station, that he had used AI “three times” for the book.
Jaenada’s three uses of AI
Jaenada’s November 4 radio remarks were relayed by the station’s post on X and by the Swiss news agency Keystone-ATS. The first use was the hidden sentence, slipped in “to play with the readers.” He revealed it only to the jurors, on the day of the award, and joked: “If it gets out, I’ll know who it came from.”
The second use was “to make fun of ChatGPT a bit,” over what he called its “completely absurd answers about a technical detail.” The third was technical research for the book. The novel, his thirteenth according to Le Monde, reconstructs the unsolved 1949 killing of a young woman in Paris.
“We can’t push AI away, we can’t act as if it doesn’t exist,” he said on air. “We have to use it, acknowledge it, tame it and not let ourselves be replaced. It has to be useful.”
The AI use was no secret from readers, as the French daily 20 Minutes pointed out on November 4. On pages 237 to 240 of the novel, on sale since August, Jaenada asks the chatbots ChatGPT and Claude whether cobblestones or hair dry faster. He prints their answers, some of them off the mark, and comments on them. He also writes that he kept one AI-generated sentence in his manuscript, and dares readers to find it.
The novel the academy dropped in September
The book was “C’était ça ou mourir” (“It Was Either That or Die”), published by Grasset. It is a debut novel about migration by Thélyson Orélien, a 38-year-old Haitian-Canadian writer. It had already won the Prix du roman Fnac, awarded by the French book retailer Fnac.
The accusation started on September 21 with an anonymous account on X called “Balance ton Claude” (roughly “Expose Your Claude”). The account cited results from Pangram, an AI-detection tool. The essayist Samuel Fitoussi later said he is one member of the group behind the account, the French public broadcaster franceinfo reported.
On September 25, the academy removed the book from its first list of 16 novels. Its statement cited plagiarism the author had committed “over time” and “the convergent result of several analyses by researchers and journalists.” The plagiarism concerned older texts, at least a short story and articles published in Canada, according to franceinfo.
The academy said it wanted to send “a clear message”: it does not endorse “in any way the creation of texts generated with the help of AI.” It addressed the message in particular to the juries of other Goncourt prizes. They include high school students for the Prix Goncourt des Lycéens, prison inmates for the Goncourt des Détenus, and student juries for more than 50 Choix Goncourt prizes abroad. About 10,000 students sit on those foreign juries, according to the academy’s website.
Not every jury followed the academy. On October 13, the Prix Renaudot, another major French literary prize, still had the novel on its second list of nine, the French news agency AFP reported. Sales had kept climbing through the scandal, past 65,000 copies by that date, the agency added.
Orélien rejected the AI claim in an October 13 statement to AFP, published by France 24: “That’s slander and heresy.” “Here and there I did use tools for research, particularly for foreign idioms,” he wrote. “But not a single sentence in this book was created by a machine.” In the same statement, he apologized for plagiarism in texts he wrote when he was “just over 20.”
On October 21, his Montreal publisher, Éditions du Boréal, ended its relationship with him and said it will not reprint the book. It said new evidence indicates that AI was used in the writing process, although the author had assured it several times that he never used it. Boréal had gathered every working version of the novel and commissioned an outside analysis, which found “traces of AI tags in the metadata of some documents.” It still does not know how far AI was used, it said, and probably never will.
What is shown and what is not
Jaenada’s sentence cannot be checked. Only he and the jurors know which one it is.
The case against Orélien rests on AI detectors and file metadata, and the academy itself wrote “in all likelihood.” The detectors disagree. AFP ran excerpts of the novel through several tools and got answers ranging from “very likely” written by a human to “100 percent” AI-generated, France 24 reported. Pangram gave a 100 percent probability.
Pangram also played a part in Dallas in October. A local magazine ran Michelin’s new restaurant reviews through it, then said AI wrote them. Michelin denies it.
The two cases also differ. Jaenada says he used AI a little, and he disclosed it in the book and again on air. Orélien is accused of using it a lot, and he denies it. Some users on X called the contrast a racial double standard, The Guardian reported on November 5.
Publishers, prizes and platforms set their own rules
Some publishers have settled the question themselves. On October 1, the publishing house L’Observatoire released the first book with a “100% humain” (“100% human”) label: Gaspard Koenig’s “Consonno.” The house now signs a contract only after the author accepts a binding agreement not to use AI to create the book, 20 Minutes and AFP reported on October 2.
Other publishers handle it differently. Albin Michel said it uses AI-detection tools, but that a human reading counts more. Actes Sud, Le Seuil, Gallimard and Robert Laffont said they use no detection software.
A new prize took the opposite route. On October 21, three tech entrepreneurs opened entries for the Prix Pascal, a French prize for books written with AI, according to Euronews. Entrants must file a technical dossier listing the AI help they used.
Video games adopted the same disclosure rule earlier. Valve has asked developers on its Steam game store to label generative AI since January 2024. Almost half of October’s new Steam games carried the label. In music, Spotify pulled more than 50 million “slop and spam” tracks from its recommendations this year.
Jaenada argued for disclosure before he won. “Would a film director hide that he uses special effects?” he told 20 Minutes in an interview published on October 2. “It must no longer be concealed, underground.” He also predicted that AI “will be the most prolific author on the planet, by far,” whether next year or in five years.
What it means
In September, the academy said it does not endorse “in any way the creation of texts generated with the help of AI.” Its November vote fits a narrower line. A use Jaenada describes as small, stated in print, did not cost him the prize. A large use, flagged by detectors and denied by the author, cost Orélien’s bestseller its place on the list, in a case that also involved past plagiarism.
That line moves the question from “was AI used?” to “did the author say so?” Detectors cannot settle the first question. A book can answer the second on the page. Disclosure is the rule Jaenada argues for, the one the Prix Pascal requires and the one Steam applies to games. The academy has not written that rule down, and it had not commented on Jaenada’s remarks when The Guardian asked on November 5.
The next test comes in mid-December, when the Prix Pascal names its first winner. The academy publishes its first list each year in early September, and it has not said whether it will set a written rule before the next one. Abroad, Orélien’s novel was due to be translated in more than 20 countries, France 24 reported. Boréal says its decisions have international reach because the novel is covered by many deals with foreign publishers.
