GoKawiilLeaked iOS 27 code shows Apple building Siri to run on Claude or GPT models
A developer who examined private iOS 27 and macOS Golden Gate frameworks found evidence that Apple has built mechanisms letting Siri delegate tasks to third-party AI models like Claude, or even swap out its own server-side model entirely for one such as GPT-5.6. In demonstrations, Claude handled tasks such as file creation while Siri still executed system actions like setting reminders, and a separate protocol showed an external model receiving Siri's planner prompts and tool definitions to perform system actions directly.
GoKawiil's interpretation of the reporting above, not reported fact.
This suggests Apple is preparing a far more flexible, modular Siri that isn't locked to its own AI models, potentially easing its well-documented struggles to compete with OpenAI and Anthropic on assistant intelligence. If confirmed and shipped, it would mark a significant shift in Apple's AI strategy toward interoperability rather than building everything in-house.
- Leaked code reveals two protocols: Model Delegation and Model Manager Services inference providing.
- Claude can act as a Siri extension, handling tasks Siri can't natively perform.
- A more radical option lets external models like GPT-5.6 fully replace Siri's server-side brain while keeping Apple's interface.
