What happened
A Graphite study compared 10,000 pre-ChatGPT articles against AI rewrites of the same articles and found 13,000 phrases at least twice as common in AI prose, defining those as 'tells.' Claude Opus 5.5's standout tell is 'dependable,' appearing 23 times more often than in human samples, plus the construction 'is more than an X, it's a Y' and the phrase 'this matters'; the older em-dash and 'delve' tells are described as stamped out. Graphite chief AI officer Greg Druck told TechCrunch that Claude models are moving closer to the human word distribution over time while GPT models are moving further away.
Why it matters
If you ship AI-written copy — README files, docs, landing pages, changelogs — you now have a concrete edit list instead of a vibe check: search your drafts for 'dependable,' 'this matters,' and 'more than an X, it's a Y' before publishing, because those are the phrases the study says read as machine-written. The model-drift finding is also a practical input if prose quality is why you picked one model over another: the study's own framing is that Claude is converging toward human word distribution and GPT is diverging, which is a reason to re-test your writing pipeline per model version rather than assuming last year's choice still holds.
Discussion angle
Paste a paragraph of AI-generated copy from your own project into a search and count how many of the study's tells it contains — then debate whether the fix is editing prompts, switching models, or accepting the tells because readers no longer notice them.
