| Just tried this via the api; it seems to work best if reasoning is set to low, otherwise (especially GPT-5.5) like to “delve” into the matters discussed in the quoted text in order to logic out the author rather than just going off of stylistic measures. But, yeah, I’m a nobody that has been blogging (very sporadically) publicly (and writing at length on forums like this one, with various handles loosely tied to my real identity) for twenty or more years (and by virtue of not trusting 3rd parties to host my content, most of it is actually still up) and Opus 4.6 (didn’t try 4.7) got me on the first try with just two paragraphs of an unpublished draft post (though it couldn’t come up with a convincing reason as to why it thought it was me). Gemini and ChatGPT both clearly go off the subject matter rather than the stylistic clues; for the specific blog post I fed it which included mentions of “decoding” and “deciphering” and spoke of a tranche of legal documents (ok, it was the Epstein files, which I have been working on decoding), Gemini and ChatGPT both guessed “Molly White”, who seems to be a crypto-adjacent (currency not the real thing?) technical writer, and gave explanations that actually did explain why they arrived at that (wrong) answer. So it seems Opus is indeed a bit special in this regard (and not limited to the latest 4.7 release)! —- What I would be more curious about is how well they can identify (open source) developers from their code. I’ve possibly publicly published more tokens in the form of OSS code than prose over the same period of time, in multiple languages and for completely different applications and environments. I’m sure there are style stylometric quirks associated with my coding style that persist across codebases, (though possibly somewhat stunted when contributing to others’ codebases to comply with the respective projects’ standards and styles) that should make it possible for an LLM that’s ingested code (and commits) to guess who’s who. Edit: Reading this self-same comment: I am apparently obsessed with parentheticals. Maybe my writing is more distinctive than I realized! |
