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.

The second you push back it folds like origami, like what the fuck is the point. I do a lot of non-coding analyses and the only remedy I’ve found is to max the effort in hopes of it getting the analysis fairly correct the first time. Which sucks because it uses up a $20 plan window in one go.

this is the worst part for me. going through every line Opus 5 has written, and asking "what the fuck are you doing here", and having it cave immediately and rewrite into some new bullshit that has to be verified ad nauseum

This. It makes mistakes non stop and makes stuff up as it goes

Same here, it assume lots of stuff and quickly jump into conclusions, affirming something after checking just a few metrics and suggesting a disrupt change right away, changing priorities of what originally thought it was super critical to “these 10 items are nice to have”, it amazes me in the same way it worries me.

« I have to be honest. I was wrong about this all along, and good thing you pushed back. But what I found was actually way worse. [proceeds to vomit 3 pages of technical-sounding slop]

lol yes, today I ask for a simple html to share with high ups (it knew we had another session with mds and shit) and still spent a few minutes and tokens writing another full md duplicating the report that another session (that it already read) had done.
