Would you please elaborate on "really decent"? Really decent for what use exactly? I want to love it (and use it as a cheaper research model in my harness), but I really cannot get any real development done with it? It stumbles and fumbles and over-complicates, where astra just plows ahead (often in less overall time) with excellent solutions.

I really want to love this model, particularly since it's good to have an open weight model on my team so to speak, but I think I might be holding it wrong.

What are you using it for?

Opus 5.5 is flat out amazing, particularly how cheap it is in practice (I'm on a subscription and use Claude Code and I almost never even approach the cap).

I would love a benchmark suite that better reflects real-world coding performance, as having Muse Wonder in the top three makes no sense to me.
