iOS 27's top on-device AI gated to Apple’s latest devices
Apple unveiled iOS 27 and a new Siri AI at WWDC 2026, but its most powerful on-device AI model will only run on newer hardware: iPhone 17 Pro or iPhone Air, plus iPad with M4+ 12GB RAM or Mac with M3+ 12GB RAM. The base iPhone 17 with 8GB RAM cannot run the top model on-device; other devices can still use many features via Private Cloud Compute, though at slower speeds.
