Claude Sonnet 5

Same price for worse performance once you go above medium effort seems kind of silly to me. Especially since low and medium effort seem to perform so poorly compared to opus. I guess similar performance at xhigh will be nice to have for folks that never touch that sonnet usage limit.

It's a 404 for now.

It's live in the API now

Is this real?

Let's wait and see if the rumors are true.
