'Obvious markers of AI': doubts raised over winner of short story prize Granta publisher says'perhaps we never will know' true authorship of work that won Commonwealth prize A few syntactical tics - and the verdict of an AI detection platform - have sparked a furore over the possibility that a short story given a prestigious literary award was written by AI. The foundation that awarded the prize and Granta, the magazine that published the winning story, said they had considered the allegations but had not reached a conclusion as to whether they were true. "It may be that the judges have now awarded a prize to an instance of AI plagiarism - we don't yet know, and perhaps we never will know," the publisher of Granta, Sigrid Rausing, said.
