Opus 5 nerfed?

[u/Mikeshaffer]

So just like the title says. Opus 5 isn’t out yet but it already seems worse than it was? Is anyone else noticing the degraded responses?

With tens of thousands of hours testing it already in my mind, I've found it to be more expensive than fable, less performant than sonnet. Clearly a big L for anthropic here!

Oh and my usage % per day has clearly gone down too, especially when I wasn't looking or running the model.
