Leaked iOS 27 Code Shows Siri Can Route Requests to ChatGPT or Claude

Summary

Hidden code in iOS 27 reveals that Apple built a model delegation system that lets Siri route requests to third-party AI models, including ChatGPT and Claude. A developer known as “pdfu” demonstrated two distinct integration methods: a shallow mode where Claude or ChatGPT interprets a request and then hands the resulting action back to Siri to execute, and a deeper mode where a third-party model fully replaces Siri’s server backend and can call Siri’s native system tools directly. Neither mode is public yet. Only the existing ChatGPT extension works in shipping builds of iOS 27.

Why it matters

Apple is building Siri as a model-agnostic orchestration layer from the start. If Apple opens the delegation entitlement to developers or users, Siri stops being a single AI assistant and becomes a system layer that routes work to whichever AI model the user prefers. That is a fundamentally different long-term strategy than building everything in-house.

HTD Says

Apple apparently baked the ability to swap Siri out for ChatGPT or Claude directly into iOS 27’s architecture, and if that ever becomes a real user-facing option, it completely changes what it means to “use Siri.” We already saw this with the first release of Apple Intelligence, where if Siri couldn’t complete a complex request, it could optionally pop out to ChatGPT if the end user had connected and enabled their personal ChatGPT account.

It sounds similar but goes deeper and offers more options. Siri becomes more like a conductor or traffic cop, routing AI-related requests appropriately if the user permits it. Being able to choose the AI model you want is important, as they do differ in the types and quality of responses they provide.

But it is too soon to know what this “feature” will actually include and do. Seeing some line in the iOS 27 code is one thing. It offers a glimpse. I expect it will be several months before we actually see some tangible functionality.
