It is 100% true. And they are rapidly losing users to Codex. Charts were shared recently showing a massive migration underway.

Oh yeah, Sonnet performance has been in the toilet for me. They claim they've mitigated it but when 4.0 first dropped CC was really impressive, and now I constantly have to babysit it because any time it hits a challenge it'll just stop trying and make a simple toy version and declare false victory. If I don't catch it and I let it build on top of that bullshit, things get nasty in a hurry.

It's a shame because the plan is a great deal but the number of all caps and profanity laced messages I'm firing off at Claude is too damned high.

		This hits home for me too. Claude feels like it has gotten more "yes-man"-y. I can no longer trust its judgement. Even if I come in with something dead wrong, I'm "absolutely right" and it finds amazing ways to spin my BS into something vaguely believable. I am also bullying Claude more nowadays. Seeing this thread, I might give Codex another go (I was on Codex CLI before Claude Code. At that time, Claude blew Codex out of the water but something's changed)

		Yes, this. I feel like I’m going crazy. I pay for the extra Opus usage and I keep checking the model switcher to see if it has automatically switched to Sonnet. It has not. I just have a lot more experiences of it feeling anecdotally dumb lately.

		GPT-5 is comparable to Opus without needing to constantly dip back down to Sonnet for cost management
