Opus is supposed to be the expensive-but-quality one, while Sonnet is the cheaper one.

So if you don't want to pay the significant premium for Opus, it seems like you can just wait a few weeks till Sonnet catches up

Strangely enough, my first test with Sonnet 4.6 via the API for a relatively simple request was more expensive ($0.11) than my average request to Opus 4.6 (~$0.07), because it used way more tokens than what I would consider necessary for the prompt.

This is an interesting trend with recent models. The smarter ones get away with a lot less thinking tokens, partially to fully negating the speed/price advantage of the smaller models.

Okay, thanks. Hard to keep all these names apart.

I'm even surprised people pay more money for some models than others.
