  "transcript": "It turns out LLMs have strong priors over character names that are model-specific and version-specific. If you find Elena Vasquez and Marcus Chen together on a website, there's a good chance Claude generated it.\n\nWe stumbled on this as a side finding while working on a model diffing method (CDD), and it grew into its own paper. The short version: these names travel as correlated ensembles, appear across dozens of websites as volcano experts, podcast hosts, thriller protagonists, and authors of 1000+ papers published in two months.\n\nThen we found a third name in the ensemble. The collage in the comments shows three different websites independently hallucinating the same trio with AI stock photo faces.\n\nPreprint: https://arxiv.org/abs/2606.02184\n\n\n\n--- Top Comments ---\n\n\n[20 upvotes] Ah, our small Elara has grown...\n\n[17 upvotes] There are 2 hard problems in computer science and apparently AI has not solved naming things\n\n[10 upvotes] Fascinating and depressing. Good work!",
