Marketing firm says Opus 5.5 writes 'this matters' 116 times more than people
Graphite compared 10,000 pre-ChatGPT articles with model rewrites and says Opus 5.5 favours 'dependable' and 'this matters', while GPT-6 Astra leans on 'not simply'.
Claude Opus 5.5 uses the phrase this matters 116 times more often than human writers do, and why X matters 92 times more often, according to a study by the marketing firm Graphite, as TechCrunch reported on Thursday. The firm also found the model uses the word dependable 23 times more often.
OpenAI's GPT-6 Astra has different habits, Graphite said. It leans on corrective framing, in which constructions such as not simply X appear more than 100 times as often as in human samples. It also refers often to another dimension and hedges with phrases like may provide and can provide.
Graphite took 10,000 articles that predate ChatGPT as its human baseline. Different AI models then rewrote those articles from summaries, which the firm did to limit bias from the source text. It identified 13,000 phrases that appear at least twice as often in the AI versions as in the human ones.
TechCrunch said older tells such as the em dash have largely been trained out, while each new model version brings distinctive patterns of its own. We have not seen the study, and TechCrunch's account does not say whether Anthropic or OpenAI responded, so the multiples are Graphite's figures and untested by anyone else.
