IMHO, Claude Opus 5.5 is living up to its claims from a non-coding perspective.
I've been working on architecture documents the last few weeks (well, the last couple of decades, but recently...) and found myself steering away from Opus for the same reason everyone else has (over-verbosity with a huge side helping of hyper-thesaurus) as well as it being overly argumentative and obstinate (as in making teenagers look positively compliant and helpful).
5.5 has none of those problems, and it's faster.
As to coding, haven't had a chance. If anyone is curious, let me know and I will share once I get to try that aspect again.
Meanwhile, good job on this one, Anthropic, and the rule of avoid #.0 - #.3 seems to still hold from the manual patches of the 90's to the forced pushed of the 20's 😏
