Canadian-Haitian author Thélyson Orélien is embroiled in a literary controversy known as the ‘Affaire Orélien’ following allegations that his bestselling novel, ‘C’était ça ou morir’, was generated using artificial intelligence.

The controversy emerged after an anonymous account on X, ‘Balance ton Claude’, used the Pangram detection tool, which reportedly identified the manuscript as being “100% AI-generated”. This has raised questions within the French publishing industry regarding how the work passed editorial scrutiny. 

Despite the allegations, the novel has seen significant commercial success in France, selling nearly 65,000 copies in six weeks. However, the scandal has had professional consequences for Orélien; he was removed from the Goncourt prize selection and cut short his promotional tour in France to return to Quebec. 

Orélien and his publisher, Grasset, have denied the accusations. The author maintains that he completed the first draft of the book between 2017 and 2019, predating the widespread availability of generative AI models like ChatGPT. He has suggested that the accusations may be an attempt to silence his voice. Additionally, Orélien is now facing accusations of plagiarism regarding his previous poetry.

The Goncourt Academy has officially removed the novel from its initial shortlist to protect the integrity of human authorship for this year’s prize. The incident has ignited a significant debate within the French publishing industry regarding the reliability of AI detection software and the distinction between using digital tools for assistance versus generative authorship. The Academy has not yet established formal rules regarding the use of digital aids.
