Apple's Siri AI Can Be Swapped Out for Claude, ChatGPT, Code Shows

Key Points:

• Apple’s upcoming iOS 27 and macOS Golden Gate releases include private frameworks revealing a new Siri architecture designed to integrate deeply with third-party AI models, such as Claude and ChatGPT, via a mechanism called Model Delegation.
• Model Delegation allows third-party AI models to function as Siri extensions, enabling users to request tasks like setting reminders or creating CSV files, where the AI interprets the request and Siri executes system-level actions if needed.
• A more advanced protocol, "Model Manager Services," could enable Apple's server-side Siri model to be fully replaced by external models like GPT-5.6, allowing these models to handle complex tasks, access personal data, and respond through Siri’s interface and voice.
• This development aligns with the European Union’s Digital Markets Act, which mandates that Apple provide third parties with effective access to iOS hardware and software features comparable to Apple’s own services, including Siri.
• Currently, the ChatGPT extension is the only third-party model available in the macOS 27 Golden Gate Release Candidate, with broader third-party access and user-facing features still pending from Apple.
