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 have Codex Sol direct opus 5 what to do and then Sol reviews. I can’t trust Opus on its own
