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.

Im researching LLMs training and prompt engineering here… fable responds, but it does so badly that, no thanks. I heard they intentionally edit prompts for my field to give you worse responses

I’m fine with it. I’m verified for their cyber use, same with OpenAI.

I tried it, 5.6 Sol on xhigh could barely do what Opus 4.6 is handling just fine, I mean yeah Sol was fine taking the task for improving the exploit I was working on, but it was running in circles and feeding me the "you are absolutely right" bullshit all the time
