Claude 4.5/4.6 - absolutely agree. Fable 5? From my (limited) testing, also reasonable to interact with.

Opus 4.7/4.8/5? Absolutely smug and antagonistic and preachy. I'm constantly fighting with it to stop fighting me and accept that I occasionally know better. It's really frustrating to spend so many tokens of such an expensive model arguing with it.

Really? I've heard so many other people complain about this recently. And maybe it's possible that it's the prompt style even. But interesting that it's not across the board.
