Opus 5 scored highest, too, which is just lol

Opus 5 is okay at coding. It is unbelievably awful to chat with, though. Very snippy, snarky, and it loves to "push back" even when it's inappropriate to do so. Besides, where "conceptual" things like science and math are concerned, it's starkly inferior to 5.6-Sol. Where writing prose is concerned, Kimi-K3 runs circles around it.

I refuse to believe Opus 5 is at the top of any non-cherrypicked benchmark, unless it has to do with very narrow coding tasks.

Maybe it gets bonus points for constantly being honest about how it didn't actually finish what you asked it to do.
