Why isn't Apple Intelligence supported on iPhone 14 Pro and 14 Pro Max?

Because Apple Intelligence requires an iphone 15 Pro on newer.

Because it lacks the necessary hardware and RAM to run it. By the way Dynamic Island is not related whatsoever to Apple Intelligence, that is an entirely separate feature.

The lowest supported device for Apple Intelligence is an iPhone 15 Pro (or Pro Max). Basically anything with an A17 chip or higher.

Alternatively, take a look at some of the exciting newly released AI solutions from companies like Google, xAI, Anthropic, Microsoft, and you'll probably find something that works for you on your iPhone 14.

I hear you how frustrating it is to have a fairly new device and it is just below the cut-line for new features. Hang in there.

The only iPhones that can support apple intelligence is iPhone 15 Pro and Pro Max and iPhone 16 models the reason why the iPhone 14 Pro and Pro Max doesn’t support apple intelligence is because it has the A16 Bionic Chip which doesn’t have enough ram to support apple intelligence only the A17 Pro Bionic Chip and later can support Apple Intelligence since it had enough ram to power it
