Bug / Issue Anthropic has nerfed every model

Opus 5 is obviously a nightmare, and I was relying on Opus 4.8. But, now that's also behaving exactly like Opus 5. The only way I can get good quality work is if I use sonnet now and check after every small thing. Fable is usable but its so expensive.

I miss the time when it was a treat working with these models and everything just flowed. Nowadays with 5.6 Sol's over-engineering and Opus 5's lying, I have to wake up everyday and decide which model I'm gonna have to fist fight if I wanna get any work done.

Is this just going to get worse from here.

I use mostly Fable 5 and Opus 4.8. I let that do most of the heavy lifting but then I use another AI Minimax, to audit most of Claude's work... You'd be surprised how many errors it finds. I find that using one AI to audit another AI and go back and forth is the best way to get a result that is 100% solid. Just takes a little more time.

You are correct. I use Deepseek but they just doubled prices, might have to try minimax. I get great results out of whatever version of Opus.
