For stuff that can't be run on phones, some of it will be run on Apple's servers, which I'm assuming Apple is eating the cost of for the time being.
Stuff that needs heavy reasoning or external knowledge will be processed by google, in exchange for $1 billion a year. However Google already pays Apple $20 billion a year for google to be the default iOS search engine, so you could view this as just changing to google paying $19 billion a year instead.
> PCC delivers a powerful server model without compromising privacy: data is never stored, used only for the request, and independently verified. It's integrated with the OS and iCloud, so there's no authentication or API keys, no token cost to developers, a daily per-user limit (higher with iCloud+), and eligibility for apps under 2M downloads.

I haven’t seen any information about what’s happening with apps over 2M downloads, who graduate from the Small Business Program. https://developer.apple.com/app-store/small-business-program...
Some of it is free on-device. Some of it is free & rate limited per day. They mentioned in the WWDC infomercial that users with iCloud+ (the storage tier subscriptions, Apple likes to throw random things in with that) will be able to get more uses per day. And some of it developers will pay for.
And even if the assumption turns out to be wrong, they can just scale down and serve dumber and cheaper models. Shrinkflation is not a novel idea.
