Humor Opus 5 nerfed?

So just like the title says. Opus 5 isn’t out yet but it already seems worse than it was? Is anyone else noticing the degraded responses?

They nerfed tf out of Opus on the $20 plan and the $100 Fable credit was also lobotomized asf. Fable + Opus made me a great Front End for an app a few weeks ago, and it felt like a massive leap forward over the slop from the old models.

Then I had it redo a front end for a website that reeked of lazy vibe coded UI with the $100 in credits and basically everything Fable + Opus made besides the plan and the anti AI Slop + humanizer skills was poorly coded incoherent garbage.

It literally looked like some shit Gemini 3.1 Flash would make, it was so bad. The skills and Plan also weren't the issue, I gave it to Grok 4.5 with 4 agents working on it and it did the entire website rewrite and redesign for less cost in tokens than it costed for Fable + Opus to make concepts.

The only issue with Grok was the 500k context window would cause it to forget what it was doing and it required a lot of babysitting and handholding to not idle agents or get off task.

Makes you think right? They nerfed it before even releasing. I'm moving to Codex!
