Developer: iOS 27 Has Private Interfaces, Allowing Third-Party Models to Replace Siri Backend
- Developer pdfu discovered that iOS 27 and macOS 27 contain undisclosed private interfaces enabling third-party apps to access Siri Extensions or replace Siri's server-side AI model.
- The developer demonstrated the capability using Claude and GPT-5.6 Terra, with the latter functioning as a server-side model capable of receiving Apple native prompts and tool definitions.
- Third-party models accessed through these interfaces can execute system operations and access personal data.
- Both implementations rely on private permissions, and Apple has recently tightened the relevant security settings.
According to a post by developer pdfu on the X platform on September 13, iOS 27 and macOS 27 contain undisclosed private interfaces that enable third-party applications to access Siri Extensions or replace the backend AI model powering Siri.
The developer demonstrated this capability using two models: Claude and GPT-5.6 Terra. GPT-5.6 Terra, functioning as a server-side model, can receive Apple's native prompts and tool definitions, execute system operations, and access personal user data.
Both implementations of third-party model integration rely on private permissions. Apple has recently implemented tighter controls on these relevant settings to restrict unauthorized access.
开发者：iOS 27 包含私有接口，允许第三方模型替换 Siri 后端
据开发者 pdfu 在 X 平台上于 9 月 13 日发布的帖子，iOS 27 和 macOS 27 包含未公开的私有接口，允许第三方应用访问 Siri Extensions 或替换 Siri 的后端 AI 模型。
该开发者使用 Claude 和 GPT-5.6 Terra 两个模型进行了演示。其中 GPT-5.6 Terra 作为服务器端模型，能够接收 Apple 的原生提示和工具定义，执行系统操作，并访问用户个人数据。
第三方模型集成的两种实现都依赖私有权限。Apple 最近已对相关设置实施了更严格的控制，以限制未授权的访问。
