GoKawiiliOS 27 code hints Apple may let users swap Siri AI for Claude or ChatGPT
A developer analyzing iOS 27 and macOS 27 code found hidden APIs that would let third-party AI models like Claude act as Siri Extensions, effectively replacing Siri's backend. The feature isn't active yet, but a demo shows Claude appearing within Siri's interface using an App Intents 'Model Delegation' mechanism.
GoKawiil's interpretation of the reporting above, not reported fact.
Letting users pick their own AI assistant would mark a major shift from Apple's historically closed approach to Siri, potentially accelerating competition among AI providers. It's unclear whether this option will roll out globally or only in the EU, where regulatory pressure has already forced Apple to open up its platforms.
- Hidden code in iOS 27/macOS 27 suggests support for swapping Siri's AI backend with third-party models.
- A demo shows Claude functioning as a Siri Extension via a Model Delegation API.
- The feature is currently inactive and may launch only in the EU due to regulatory requirements.
