This is quite the rug pull.

I've been using the Pro+ with Opus 4.6 very successfully and being charged 3x rate was mostly acceptable.

But removing Opus 4.6 and replacing with Opus 4.7 with a 7x rate is just insane!

Note that the 7.5x multiplier is only for the promotional period (until end of April), then it'll get even worse. If I had to guess it'll be priced at 10x.
