Apple's new Siri AI ships with iOS 27, iPadOS 27, macOS Golden Gate, watchOS 27, and visionOS 27, but hardware fragmentation means not every device on those updates gets the same features. On-device AI processing requirements draw a hard line between supported and unsupported hardware, and some Apple Intelligence features are locked exclusively to newer silicon.
The video is worth watching in full because it maps out exactly which iPhones, iPads, Macs, Apple Watches, and Vision Pro units clear the threshold, and which ones receive iOS 27 as a stripped-down update with no Apple Intelligence at all. The breakdown of iCloud+ as a potential AI subscription tier is the detail most coverage has ignored.
This is a compatibility guide, not a hype piece. If you are deciding whether to upgrade hardware ahead of the fall release, or trying to understand why two devices running the same OS version behave differently, this video gives you the specific device list before the official rollout.
