Goncourt drops Thélyson Orélien novel after AI authorship allegations

The Académie Goncourt removed Thélyson Orélien’s novel *C’était ça ou mourir* from its first selection on 25 September 2026, ending the book’s chances of winning this year’s French literary prize amid allegations about AI authorship and plagiarism. [2]

The organiser said it considered the novel highly likely to be largely the product of artificial intelligence, citing converging analyses by researchers and journalists. It also cited reports of plagiarism in Orélien’s earlier work, saying the removal was intended to protect the integrity of the prize. [2]

That is the Académie’s assessment, not an independently demonstrated account of the book’s authorship. Its statement does not identify the researchers or reports behind its conclusion, or provide their test data. [2]

Orélien has denied using AI. According to ActuaLitté’s reporting on 22 September, he rejected the allegation in comments to Libération and said in a separate declaration that he began the novel in autumn 2017 and completed its first draft in 2019. He attributed its imagery, repetitions and rhythms to his Haitian and Caribbean literary traditions. Grasset expressed its full confidence in him. [3]

No dated manuscript or verifiable revision history is available in the supplied evidence to substantiate that chronology. An early first draft would not, by itself, rule out later AI-assisted revisions.

What the detector results show

ActuaLitté reported that franceinfo submitted several excerpts to the free version of Pangram, which classified all the submitted words as written with AI assistance. Another detector, GPTZero, assigned one excerpt an 87% probability of AI authorship. Those figures represent different detector outputs, not verified proportions of AI-written content in the novel. [3]

The same account included comparisons: Pangram classified two older Orélien texts, from 2014 and 2015, as wholly human-written, and excerpts from four other new novels as 99–100% human. It did not specify the total number of words or proportion of Orélien’s novel tested. [3]

Research offers a reason for caution without dismissing the tools outright. In a June study of academic texts, all four detectors evaluated correctly identified the fully human examples. Nevertheless, the researchers warned against using detector results as the sole evidence in high-stakes decisions. That study did not establish their accuracy for this French-language novel. [5]

The historical plagiarism allegations are a separate issue. TVA Nouvelles/Le Journal reported similarities between Orélien’s contributions published in 2012–2014 and earlier texts by others. It said he had not responded to those allegations by publication on 23 September. Those comparisons do not establish AI use in the novel. [6]
