Opus 5.5 is awesome

If the entire industry stopped training new models, and just served Opus 5.5, I would be perfectly satisfied.
I don't know about its absolute performance, but Opus 5.5 is very "tasteful". It came out a week after I switched from Codex and started lamenting how much worse Opus felt to use than Sol, but whatever Anthropic did to fix it worked.
Hopefully this isn't a fluke and they'll be able to keep on track with future releases.
