Apple's Siri AI Can Be Swapped Out for Claude, ChatGPT, Code Shows
Leaked code suggests Apple is developing a deep integration for third-party AI models within its Siri architecture. The system, dubbed 'Model Delegation,' would allow users to swap Apple's native AI for models like Claude or GPT-5.6 for specific tasks.
Why it matters
This move signals a potential shift in Apple's 'walled garden' strategy, allowing for greater interoperability with external AI providers to maintain competitiveness in the generative AI space.
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. In pdf's video, shared on X , the macOS user brings up the "Search or Ask" bar and chooses Claude as the AI model via an "Ask..." contextual menu.
After enabling the Claude extension, the user asks Siri to "Ask Claude" to set a reminder in Apple's Reminders app. Claude then interprets the natural language reminder request and Siri subsequently creates the reminder. The implication is that if the request requires access to an Apple system feature, Claude hands the task back to Siri.
