Apple limits new Siri AI to iPhone 15 Pro and newer, driving a hardware upgrade cycle

After two iOS cycles came and went without the supercharged assistant Apple promised, iOS 27 finally delivers a rebuilt Siri that handles complex, chained commands and references personal context from Notes, Messages, Mail and Photos. Engadget and 9to5Mac, who went hands-on, describe it as the first genuinely useful version — but only for a subset of devices.

The hardware gate is the story. Only Apple Intelligence-compatible devices — every iPhone since the iPhone 15 Pro, Apple-silicon iPads and Macs, and the 2024 iPad mini (same SoC as the 15 Pro) — get Siri AI. iOS 27 itself installs on phones as old as the iPhone 11, but those users get little of the marquee AI functionality. Analysts (including Forbes' Ewan Spence) frame this as Apple using proprietary AI requirements to trigger a replacement cycle, with iOS 27 the first release where 'most new features are AI-based.'

Technically, Siri AI leans on on-device Apple Foundation Models for speed and privacy, offloading heavier queries to Private Cloud Compute. Apple is shipping it as an opt-in beta first, echoing the developer-beta waitlist approach.

Two caveats loom. The advanced Siri will not launch in the EU due to ongoing Digital Markets Act compliance disagreements — a growing pattern of Apple withholding AI features from Europe. And Apple's own research this week (multi-agent teams underperforming single experts) suggests internal caution about over-promising agentic capability. What to watch: real-world reliability of the beta and whether the device gate actually moves upgrade numbers.
