Apple explores multi-model selection in iOS 27

Apple's iOS 27 may introduce multi-model AI selection, letting users swap third-party models into Siri and native writing tools, a significant architectural shift from Apple's closed, on-device inference stack. This mirrors OpenAI and Google's ecosystem plays but at OS-level integration depth. Developers and enterprise users gain deployment flexibility, reducing vendor lock-in across Apple's 1B+ active device base.
