Apple built a way for Siri to use multiple AI models and then said nothing about it at its own developer conference.
The iOS 27 developer beta, released after Apple's June 8 WWDC keynote, contains an Extensions framework that never appeared on stage. The system would let iPhone users choose their preferred AI engine from ChatGPT, Anthropic's Claude, or Google's Gemini, with the selection controlled from a settings panel inside Siri. Bloomberg's Mark Gurman reported on the implementation. Apple made no public reference to any of it during the keynote or in accompanying developer session materials.
If Apple ships the feature, it would mark a notable shift in how the company handles AI. Rather than building a proprietary model, Apple would be letting rivals run at the core of Siri, the interface that handles voice commands, on-screen context, and personal data. That is either a pragmatic acknowledgment that Apple's own models aren't ready yet, or a deliberate hedge against picking a winner in a market still moving fast.
The feature could ship with iOS 27 this fall, or it could quietly disappear before release. Apple has a long history of building things into developer betas that never reach users.
