I'm dubious about AI detection tools as presumably AI is trained on the vast amount of classic fiction and journals in the public domain. A story I wrote 20 years ago came back as 43% AI written on one, so make of that what you will. Still, this graph from Pangram is concerning.
We tested every Commonwealth Short Story Prize winner since 2012. We found three more AI-generated stories -- two among the 2026 winners, as well as the 2025 overall winner.
