regarding the new pro max subscription btw:

it's 500$ for 25x the plus usage, thats pro (max).

this implies that the old 200$ 20x pro (more) is now more like 10x the usage of plus.

they are slashing our subscriptions in half and make it "but we're more efficient!"

Which they are, so another way to see it would be that they make the API/enterprise cheaper.

However, I don't know how future larger models such as the cancelled 6.1 Astra will be priced.

If the price stays high, this would indeed be quite bad for the $200 subscription..
