Yes. I'd say I started to notice it 2 or 3 weeks ago. It began before Opus 5 was released, Opus 4.8 started taking a lot longer for simple responses. I switched to Opus 5 the day it was released and it's the same, seems to take a longer than it ever did, but I suppose Anthropic's user base is still increasing exponentially, maybe they're starting to spread their compute too thin across all the requests.
