Apple Intelligence Requirements: Which Apple Devices Get the Most Powerful AI?

Apple Intelligence is getting a significant upgrade with iOS 27. But WWDC26 made one thing very clear: not every device that supports Apple Intelligence will get the same experience. The better your hardware, the more you get. And for the top tier, only a handful of devices make the cut.

What Apple Actually Said

During the WWDC26 keynote, Apple's SVP of Software Engineering Craig Federighi put it plainly: "Our most powerful on-device model and the features it enables, like expressive voices and more advanced dictation, will be coming to our most capable iPhone, iPad, and Mac systems."

That's Apple's way of saying the new stuff has a hardware gate. The update rolls out to a wide range of devices, but the most capable AI model stays on the newest, most powerful ones.

The Devices That Get Everything

To run Apple's most powerful on-device AI model, you need one of the following:

iPhone: iPhone Air or iPhone 17 Pro / 17 Pro Max

iPad: Any iPad with an M4 chip and at least 12GB of unified memory

Mac: Any Mac with an M3 chip or newer and at least 12GB of unified memory

Apple Watch: Series 10 or newer (Series 10, Series 11, Ultra 2, Ultra 3)

The common thread here is memory. Apple's most advanced on-device model requires a minimum of 12GB of unified memory. That's the threshold, and anything below it doesn't qualify.

Why the Standard iPhone 17 Is Left Out

This is the part that's catching people off guard. The base iPhone 17 ships with 8GB of RAM. That's the same amount Apple has required since Apple Intelligence launched, and it's been enough for everything up until now.

iOS 27 changes that. For the first time, Apple has raised the memory bar for its top-tier AI, which means the standard iPhone 17 sits below the new cutoff despite being a current-generation device. Even the iPhone 16 Pro and 16 Pro Max, which were marketed as Apple Intelligence phones when they launched, won't get the full experience.

If you're on 8GB hardware, you'll still get plenty of Apple Intelligence features. The difference is that some of the heavier workloads will route through Apple's Private Cloud Compute instead of running fully on-device. It'll be slower and won't include the new features tied to the most powerful model, like expressive voices and the more advanced dictation capabilities Apple showed off at the keynote.

The Watch Side of This

On Apple Watch, Apple Intelligence including Siri AI is limited to the Series 10 and newer. The Series 9 gets watchOS 27, but Apple Intelligence doesn't come with it. So you're getting a software update, just not the headline AI features that Apple spent most of its watchOS stage time talking about.

On top of that, to actually use Apple Intelligence on your Apple Watch at all, you need it paired with an iPhone 15 Pro, iPhone 15 Pro Max, or any iPhone 16 model or newer. The watch itself doesn't process those workloads. It leans on the paired iPhone to do the heavy lifting.

The Mac Story Is Similar

For Mac users, Apple Silicon is now a hard requirement for macOS 27. Intel Macs are done. But even within Apple Silicon, there's a split. Apple's most powerful on-device AI model only runs on M3 or newer chips with at least 12GB of memory. If you've got an M1 or M2 Mac, or even an M4 with 8GB of RAM, you're not getting the full experience either.

What This Means Going Forward

Apple is building a two-speed Apple Intelligence ecosystem. A wide base of devices gets access to the features. A smaller group of newer, higher-spec devices gets the most powerful version of them.

It's not entirely surprising. Running large AI models on-device needs memory, and there's only so much you can do with 8GB. But it does mean that "supports Apple Intelligence" is no longer a single category. It matters which tier your device lands in, and that distinction is only going to get more important as Apple keeps building on top of this foundation.
