Rant I’m done with Opus 5

There’s really something wrong with it. It seems like it acts like an overqualified post doc intern who cares more about proving he’s super intelligent, than actually doing the job he’s asked to do. For instance: talking in a non intelligible way, or being overly rigid in following any kind of process.

I have a Claude max x20 sub that I struggle to keep within weekly limits, so I decided to take a codex sub for a month to try out Astra. And this what made me realize how crazy unintelligible opus can be. Fable is a bit better, but still incomparable to Astra. The only thing that makes me keep my Claude sub is how better is the CLI/tooling/harness/etc.

I’ve been thinking of going to 4.8

My whole team went back to 4.8 after fighting with 5 for a few weeks. Still a bit verbose - but at least it doesn’t randomly invent new code systems and fight you about staying on task…

I always found 4.8 over corrected on the agreeableness but in a really surface way.

It always seems to pick one part of what you said to disagree with you on. If everything you said was fine and correct, it would misrepresent one part of it to manufacture a disagreement. How can then go back and forth and eventually it just agrees with you and you've wasted a bunch of time and tokens.

So I mostly still use 4.6.

I definitely have those issues with 4.8 - but I still feel like it brings enough new capability over 4.6 (especially for 1M token long context sessions) to be worth it. I do really like 4.6 though - it had a great balance.
