Comparing to Opus 5: Claude Opus 5 (Uncached Input $5/M Cached Input $0.50/M Output $25/M) but you also pay a premium on Cache write 25% for 5m and 100% for 1h.

Then there’s the questions of token efficiency and token quality.
I have to say cc opus 5 is abysmal. It talks to itself incessantly, gets stuck in minutia, fails to understand problems clearly and makes steering mistakes constantly. It also has a weird behavior where it says “ok I know exactly what to do and I will start now,” then sits waiting for user input. If you’re not on the ball you’re constantly losing 5m/1h cache. Just give me back 4.6.
Fable ends up in a confusion loop for me all the time.
I still see Opus 4.6 available in CC.
Also I have been using Opus 5 for the last few days and I find it work fine. It's a little verbose but the code quality is good.
