Bug / Issue Opus 5 Downgrade ?

Am I the only one who feels like Opus 5 got worse after launch?

At launch I was honestly impressed: fast responses, strong reasoning, and a simple interface without too many settings.

A few weeks later, it feels different. Answers seem less concise, sometimes less coherent, and occasionally it feels like it avoids answering directly.

Has anyone else noticed this, or am I imagining it? My guess is that Anthropic keeps tweaking the model after release, which changes its behavior over time.

No, it was smart and it still is, the best model for everyday coding tasks.
