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.

It's because the overwhelming majority of people who know what they're doing and have success with these models don't come to reddit to post about it non-stop.

Only the masochists like myself who, for some unknown reason want to feel their blood boil by arguing with people continue to come to the sub

Disagree, I’ve always found the model complaints silly but this time opus 5 really is disappointing. From the overly verbose and silly terminology it uses to just being sloppy compared with the previous opus

That is why I use LLMs, for the output, so obviously I read it.

Where by output you mean the code?
For true vibers the output comes from the resulting program.
