827a | on: The iPhone's Last Stand?
I have consumed a decent amount of literature coming out of WWDC and I do not understand how the billing and model availability side of things will work.

Its definitely the case that Apple said that some AI capabilities will rely on cloud hosted models; and that some of these capabilities will be metered; and that "some paid iCloud+ plans" include increased usage. Its unclear what the full extent of capabilities that rely on cloud models are. We know that Spatial Reframing is a capability that relies on cloud models and will be metered; this was stated on-stage. The typical conversations with Siri are, supposedly, a mix, possibly based on how complex the query is? We know there are two cloud-hosted models (what they call internally "Cloud" and "Cloud Pro"); are both of these metered? Does it depend on the use-case (e.g. is Spatial Reframing metered because of its use-case or because of which model it uses?)

A lot of this would be easier to figure out if there was, somewhere, a "meter" you could see drop every time you used a metered feature; but there isn't. There is zero indication of metered AI usage anywhere in the settings that I have found (I am on the 27 dev beta). There is also zero indication that any of the iCloud+ plans include metered AI usage. It is also of note that Apple very specifically said on-stage that "some iCloud+ plans" include increased usage; implying that the $2.99/mo plan likely does not.

Apple has also announced that developers under a certain revenue number can use their foundation models in private cloud compute for free [1]. This implies: third party developers will pay for it. In other words: it might be the case that your shared iCloud+ pool of AI usage only applies to AI capabilities from first-party Apple apps, while in third-party apps the developers are expected to front the bill. Which further reinforces your point: Why would anyone choose to integrate with these cloud models?

Strange situation, and unlike Apple; they seem very frantic.

Freemium is a potentially interesting model for app developers. If you're small enough to be in the free tier, you can avoid the risk of someone turning your app into the next backend for Chipotlai Max and running up your AI bill.

Once you get enough downloads to where Apple starts wanting to charge you money, you can consider switching to OpenAI or Anthropic or Google or Deepseek or whatever. Sounds like they've even made that relatively easy to do in the Foundation Models framework -- just implement the LanguageModel protocol. I expect open-source or provider-written adapters to pop up that would let you use your vendor of choice.

Motra, my workout app on iPhone (with great Apple Watch support, including counting reps), uses Apple foundation models to build a workout.

Not all use cases will be big agentic coding things that will use millions of tokens.

Some on device (or on server) stuff might be small one shot calls that just use what’s the OS provides.
