Apple Intelligence Now Spans Entire Device Ecosystem, Including Watch and Vision Pro

At WWDC25 on June 9, Apple extended Apple Intelligence—its tiered ML architecture combining on-device processing and Private Cloud Compute—to watchOS and visionOS, joining iPhone, iPad, and Mac. The expansion implies either compressed on-device models for power-constrained devices or more aggressive offloading logic. New capabilities include contextual Siri awareness and cross-app reasoning chains. Latency profiles for those workflows on smaller devices remain to be benchmarked once betas ship.
