Publisher suspends presentations of its prize-winning novel for review after an El País Pangram check reported 99% AI text; the author denies using AI
El País checked the winning novel of the first Almadía Ventosa-Arrufat short-novel prize (20,000 euros; the rules banned generative AI) with the Pangram AI-text detector, which scored 99% of the roughly 26,000-word text as AI-generated, according to outlets relaying the investigation. El País passed its suspicions to the Mexican publisher Almadía, which on Friday 23 October 2026 announced a detailed review, saying it would not anticipate conclusions, and suspended all activities presenting the book, including a planned tour in Madrid, Barcelona, Seville and Cádiz. The publisher said the Peruvian author had declared in his contract and personally that he did not use AI, and that neither the jury nor its editors had seen signs of AI use. In a statement on Instagram reported by La Nación on 29 October 2026, the author said he conceived, wrote and revised the novel without generative AI tools and was gathering earlier manuscript versions, his notebook and research materials to give to the publisher for its review. Writers objected that a detector score is not conclusive proof of authorship. Whether AI was used is unestablished.
