According to Bloomberg reports, Apple is introducing Extensions — a new capability inside the Settings app, nested under Apple Intelligence. Users will be able to choose which AI model handles which task, surfaced across the system in three primary surfaces:

This builds on the existing ChatGPT integration but dramatically expands it. Testing is already underway with two named partners; any compatible model from the App Store could, in principle, join the roster.

The framing matters: Apple devices become flexible AI hubs, blending on-device privacy with whichever cloud model the user prefers. The default is still Apple. The choice is now yours.

Siri is getting its biggest overhaul yet. The shape is familiar from every other AI assistant on the market — but Apple has, until now, refused to ship it.

One of the most practical upgrades is also the easiest to demo: a new Apple Intelligence Tools section inside the Photos editor, grouping four capabilities under one roof.

These on-device tools promise speed and privacy that the cloud-only competition cannot match. The trade is quality ceiling for round-trip latency — Apple is betting users will take the trade.

iOS 27 signals Apple's recognition that no single company dominates every AI use case. By opening up while keeping on-device processing and Private Cloud Compute as the foundation, Apple strengthens its ecosystem without spending its trust capital.

For developers, this is a new distribution lane on the most lucrative platform in consumer software. For users, it is more choice, better performance, and — for the first time in years — a real reason to care about what's running underneath the chrome. The iPhone is evolving from a device that has AI features into a platform that chooses the best AI for you.
