They test it on launch day, then benchmark it against that. A deviation of above 10% is considered a change. They're currently tracking Opus 5.5 and GPT-6 Astra.
This bench famously detected a degradation of Opus 4.6 which Anthropic later blogged about. I personally think people sense nerfs more often than they happen and that it's often about honeymoon effects.
you can't explain honeymoon effects. like wow wow wow and then suddenly: same task, lesser performance is a misperception?
my fair lady gained a bit weight and the bjs lack variety?
[ I'm certain that that's a quote from some time ago by some commenter in a thread with a similar or even the same context ...but my Amnesia (Ｔ▽Ｔ ):･ﾟ:･ﾟ] fuck off.
you open two files, before and after you notice a nerf, and from worse comments to logical oversights, it's all damn obvious.
don't normalize this make believe bullshit and misleading people who you think barely understand what they see anyway ...
you wouldn't even know if models had somehow timed nerfs hardcoded into them, however much control over the stack you have.
