Graphite study: Claude Opus 5.5 says 'this matters' most; GPT models' writing is moving further from human style
Opus 5.5 loves to tell you ‘this matters’ (and other AI writing tells)
What happened
A Graphite study found that Claude Opus 5.5 uses 'this matters' 116 times more often than people and 'why X matters' 92 times more often. Its most distinctive word is 'dependable', used 23 times more often. OpenAI's Astra favors corrective frames such as 'another dimension' and 'not simply X'; the latter appears more than 100 times as often as in human writing.
