Apple Siri架构支持第三方AI模型替换

代码分析者通过审查iOS 27和macOS Golden Gate中的私有框架发现，Apple已将Siri的架构设计为可支持第三方AI模型集成1。通过名为Model Delegation的机制，Claude和ChatGPT等第三方模型可以作为Siri扩展运行，并能够访问Apple的系统功能1。在演示中，ChatGPT扩展能够查找特定主题的邮件、总结内容，并通过Messages应用发送消息1。

Model Manager Services中的推理提供程序显示，Apple服务端的Siri模型可被完全替换，例如被GPT-5.6所取代1。这一架构设计的推出很可能受到了欧盟数字市场法的推动，该法规要求Apple向第三方提供对iOS硬件和软件功能的有效访问权1。欧盟委员会已明确表示这一原则同样适用于Siri1。在macOS 27 Golden Gate版本中，"Ask..."功能的实现目前仅限于ChatGPT扩展1。

Code analysis has revealed that Apple has architected Siri to enable integration with third-party artificial intelligence models in iOS 27 and macOS Golden Gate 1. Through a "Model Delegation" mechanism, competing AI systems such as Claude and ChatGPT can operate as Siri extensions while gaining access to Apple's system capabilities 1.

According to the technical findings, Apple's "Model Manager Services" framework permits the company's server-side Siri model to be entirely replaced by alternative systems like GPT-5.6 1. In demonstration scenarios, ChatGPT was able to locate emails on specific topics, summarize their contents, and transmit messages through the Messages application 1.

This design appears motivated by the European Union's Digital Markets Act, which mandates that Apple provide third parties with effective access to iOS hardware and software features 1. The European Commission has explicitly stated this requirement extends to Siri 1. On macOS 27 Golden Gate, the "Ask..." implementation currently remains limited to ChatGPT extensions 1.
