IT之家 reports Apple is testing Siri’s local Skimmer module in iOS/macOS 27.3 beta

According to IT之家, a source on X said Apple has added a front-end module called Skimmer to Siri AI in the first developer beta of iOS/macOS 27.3. The leak says about 2% of English Siri requests are routed to a local model while the device is online, mainly for fixed commands such as setting timers, playing music and making calls. It also says the system uses rule matching to trigger tool flows directly, reducing latency and compute use.
