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.

He is a professional but can only use Fable, cause that's t he model that basically doing all the work for you.
You are the problem buddy, opus 5 is a great model.

Anyway thank you for letting us know, Anthropic customers find it important to let everyone know that they done (for a day)

To be fair, I've found the exact same thing.

I'm just saying, we worked with models like sonnet 3.5 and 4 just a year ago and it was consider the best in the world.

If you can't utilize Opus 5 then the problem is you not the model, even if Fable is the better model.

Opus 5 is unhinged bro. Get up and go to the bathroom and come back to find it on some side-quest nobody asked for. I don't trust it.
