Key Points
- Apple's iOS 27 and macOS Golden Gate code shows Siri can delegate requests to third-party models such as Claude and potentially replace its server-side model with GPT-5.6.
- A Claude Siri extension demonstrated by code sleuth pdfu can interpret a natural-language reminder request and hand it back to Siri to create the reminder, while also generating a CSV file Siri cannot make.
- The macOS 27 Release Candidate currently exposes the "Ask..." interface only for ChatGPT, and Apple has not opened the model-delegation entitlement to third parties.
