Apple's Siri AI Can Be Swapped Out for Claude, ChatGPT, Code Shows
Code analysis of iOS 27 and macOS Golden Gate frameworks shows Apple engineered Siri to deeply interoperate with third-party AI models like Claude and GPT-5.6.
Code sleuth 'pdfu' uncovered private frameworks in iOS 27 and macOS Golden Gate revealing a 'Model Delegation' mechanism that lets Claude act as a Siri extension like the built-in ChatGPT extension. A second 'Inference Providing' protocol in Model Manager Services can fully replace Siri's server-side model with models such as GPT-5.6, which then receives Apple's Siri planner prompt and tool definitions to perform system actions and process personal data. The EU Digital Markets Act, which requires Apple to give third parties effective access to iOS features, may have shaped this approach. The entitlement is not yet open to third parties and Claude is not yet available in the macOS 27 Golden Gate RC.
- Model Delegation lets Claude appear as a Siri extension beside built-in ChatGPT integration.
- Inference Providing protocol can fully replace Siri's server-side model with GPT-5.6.
- Replaced models receive Siri planner prompts and tool definitions enabling system actions.
- EU Digital Markets Act likely pushed Apple toward third-party model interoperability.
- Feature is not user-facing and entitlement is not yet opened to third parties.

Code sleuth "pdfu" has uncovered iOS 27 and macOS Golden Gate private frameworks that show Apple has designed its new Siri architecture to work with third-party AI models at what appears to be a surprisingly deep level. One mechanism called Model Delegation allows Claude to appear as a Siri extension in the same way as the existing built-in ChatGPT extension.
