Third-Party AI Models Now Supported in Siri
Apple’s latest operating systems, iOS 27 and macOS Golden Gate, include hidden support for third-party artificial intelligence models Claude and GPT-5.6 within the Siri voice assistant. This integration could significantly enhance Siri’s capabilities by allowing it to leverage advanced AI technologies. Developer pdfu uncovered private framework code that reveals how these AI models connect with Siri.
How the Integration Works
The code shows two key protocols enabling this functionality. The first, called Model Delegation, lets an external AI model interpret user requests, after which Siri carries out system commands. The second, Inference Provider, allows Siri’s default server-based model to be replaced with a third-party AI like GPT-5.6. Through this protocol, ChatGPT can receive Siri’s planning prompts, tool descriptions, and personal user data to generate responses that Siri then vocalizes.
Currently, the 'Ask…' menu is functional only with the ChatGPT extension on macOS 27 Golden Gate’s Release Candidate version; support for Claude is not yet available. Furthermore, Apple has not yet opened model delegation to third-party developers, limiting broader integration possibilities for now.
It is worth noting that on September 9, Apple unveiled new products including the iPhone 18 Pro, iPhone 18 Pro Max, the foldable iPhone Duo, updated Apple Watch models, and AirPods 5. The official release of iOS 27 is scheduled for September 14, underscoring Apple’s ongoing commitment to enhancing its ecosystem.

Integrating powerful AI models like GPT-5.6 has the potential to dramatically improve user interactions with Siri by providing more accurate and context-aware responses. However, current restrictions on third-party model delegation mean these advancements are still in the early stages of being fully realized.
In addition to the recent AI advancements, Apple's ongoing innovations have also led to significant changes in how users interact with applications like iMessage on Mac.
