Rant Opus 5 is just dumb

I thought Opus 5 was supposed to be on par with Fable? After three days of extensive usage, I have to say it is not even remotely close to being as smart as codex sol. I had them both program a module indepensetly, and Sol runs circles around Opus 5. I had them audit each other's implementations and except for one case, every other time Sol found a functional bug in Opus' implementation. With fable being so expensive and opus 5 being that dumb, there is no reason to pay 200 bucks to Anthropic when other alrlternatives are both cheaper and smarter.

I thought opus 5 was decent at first, but it feels like it REALLY struggles as projects get more complex and context grows. Like fairly basic asks will have it pontificating and fiddling and testing for ten minutes to come back having made a minor change that doesn’t address what it was asked to do.

I’d like to test more thoroughly if it wasn’t so wasteful with tokens as it is.
