When you're on a mature codebase with 500k+ lines of code, I haven't seen anything else be as effective as 4.7.
It was given very simple ways to verify success. It simply didn't do that and said it's at a good stopping point, despite moving in the WRONG direction not even doing 1% of the task, and being told to see the task through to completion.
Meanwhile, Codex broke it down into 3 steps and just got it done...
No, "I'm going to give it to you straight, this is a large risky commit that could go sideways, so I'm just not going to do anything instead."
Claude worked on it for almost 200 commits over 2 weeks, needing to typically prompt it 3x to even TRY to make any progress instead of just wasting tokens to ignore me and tell me how big and risky it is.
Maybe Claude is just particularly terrible at this type of refactor. I'm not sure why that would be.
People heard "Claude is nerfed" and now they see it everywhere, they notice failures a lot more than they would have otherwise.
Doesn't matter that Claude is not, in fact, nerfed. Perception is powerful and most humans are not rational.
However that's just it, you just need to improve and make clearer of your prompt and it will perform just as good.
Opus has been dumb this week.
Claude was having a lot of capacity problems and downtime and then this week that has been much less obvious... and the model is dumber.
It could also just be luck and my impressions are false... who knows.
It's a good thing that hype-chasers are cancelling though. So we can use the services with a reasonable latency.
