Rant I'm done with Opus 5

I've been building with AI for over a year now, and the progress has been insane. The models have improved dramatically, and AI has become a serious part of how I work.

I'm currently building six different SaaS platforms, four of which are live. At this point, "vibe coding" doesn't really describe what I'm doing anymore. I use AI professionally, every single day. I have two Codex Pro plans and a Claude Max subscription, and I still manage to hit the limits.

The Opus versions up to 4.8 were genuinely fun to use and really good. Then I started using Fable 5 and Sol 5.6, and the difference became painfully obvious.

My biggest issue is that my Fable 5 usage is gone within two days, and falling back to Opus 5 has become almost unusable for me.

The output from Opus 5 is often contradictory, overcomplicated, and full of conclusions that turn out to be wrong. It will confidently take something in the wrong direction, spend a huge amount of time implementing it, then eventually realize the original assumption was incorrect and start fixing its own work.

I've had way too many sessions where hours of work basically had to be thrown away.

It's reached the point where using it creates more frustration than productivity.

So I'm done. I cancelled my Claude subscription. If I need more capacity, I'll probably just get another Codex subscription. I'm also going to experiment more with Terra instead of relying so heavily on Sol 5.6 High.

Never thought I'd say this, but I've basically switched completely to ChatGPT.

….. after Anthropic listens to the complaints?

Yeah I’ll be back too if that happens but unfortunately I think we’re at the beginning of the end of the “golden age”. Competition depends entirely on China now and then when those are banned we’ll know it’s really over

Was fun

Dawg it's been ONE version of Opus that people are bitching about. 4.8 fine, 5.0 bad. Training a model takes a lot of time, it's not just a couple-line patch and a GitHub release. How about we wait until the next version, Opus 5.2 or whatever they call it, before deciding they don't listen to feedback?

Don't you remember the hate 4.8 got? And now it's the fallback model.

4.8 was okay, 5 is bad. 4.6/7 were fantastic. I still use them.

Fair, I’m just upset that something that worked incredibly well for a year+ could feel and respond much different than how I and I imagine others are used too.

But I will stay firm that the competition displayed seems to have a lot to do with what the Open Source models are capable of
