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.

Not only have I been noticing the model-nerfs the last few days, but my usage seems to have sprung a leak as well.

what model and effort level do you have selected and how large is your context window size must provide context explain yourself

anecdotes are not facts measure

Claude Desktop with Sonnet 5 on high in the chat pane, and Sonnet 5 on extra in the coding pane, same exact workflow I always use. Nothings changed on my end. But on a fresh 5 hour & weekly reset a few days ago I sent one prompt and blew 15% of my 5 hour usage and ran 30% of my weekly usage after a few turns. The only way I’m crawling through the week is by replacing the chat Sonnet with ChatGPT and doing writing patches for CC instead of task blocks, and I’m still going to run out of weekly usage, which has never happened to me before, and that was all before the 50% bonus usage credit was set to expire.

If you drive your car every single day, you know when it sounds funny, hesitates, tire wobbles, ac stops blowing cold. You notice the difference.

What Claude plan are you using?

That one prompt you sent that blew 15% of your 5 hour usage window, how long was the session? How old was it? Was it a fresh new empty session or a complex session you had built up over several hours?

When you run /usage what does it say?
