This matches my experience of Opus 5 being a nice improvement over Opus 4.8, but not being revolutionary like Fable felt.

I’ve now replaced my use of Opus 4.8 xhigh with Opus 5 medium, and I’m using less tokens and it’s quicker. I can understand people being annoyed by its writing style but for getting work done that really doesn’t bother me. I’ve been really enjoying using it.

I think they neutered Fable. When it first came out it was indeed revolutionary. But what we have today, is not what we had before the ban.

Medium vs High? Why? From all the charts I've seen the performance jump is pretty large from med -> high (not as noticeable from high -> xhigh).
