Hah absolutely, after of a very intense project I’ve undertaken with Claude agent teams for a few months now, I have caught myself using opus expressions, since they come to mind now naturally because that’s most of the text I’ve read since then … I’m catching myself so far, but in a year or two maybe I will not, fable doesn’t do as much “mannerisms” and speaks plainly, so maybe by then we will all be running fable level models on hour local machines and just not notice it anymore?
I've had that happen to me. I actually recently wrote a draft blog and looked over it, and it felt AI generated. My writing style has definitely changed.
I can't name one but I can tell you these models keep getting stupider as they keep existing and their system prompts get inflated with what not to do. I have experienced this happen with Qwen 3.8 Max Preview where for the early days it was blasting through Rust code fine and then before the release it silently got replaced and started to suck hard. Claude still has the "blue button" problem so it is probable that a casual chat with it could have this exact outcome of forgetting what to do. I saw some models also have this thing where when you tell them a text restriction they first ignore it in thinking, creating the full text and then apply them in their thinking rewriting it fully causing your output tokens to be inflated.
I have the opposite, I can pick up AIsms much more now and they stick out like a sore thumb. A couple of years ago I had no such intuition, it just sounded like normal writing to me, but now if I try to use AI to write any prose it just sounds absolutely terrible.
