WWDC Apple has revealed that it created its own data center stack – servers with its internal silicon and operating system – at its Worldwide Developer Conference (WWDC) on Monday.

Cupertino hasn't actually announced the servers or the operating system (and never addressed rumors of its plan to make data center-grade processors). Instead, references to the chips and the OS can be found scattered across the blizzard of announcements about AI features and product updates.

These AI features rely on what Apple calls "Private Cloud Compute" — an environment outside of the device where iGiant runs "larger, server-based models" that do AI better than the models Cupertino loads on its iThings.

Apple describes the devices in Private Cloud Compute as "custom server hardware that brings the power and security of Apple silicon to the data center." Cupertino also uses the term "compute node," but it's unclear if that's a synonym for "server." Apple has further confused things by discussing a "Private Cloud Compute cluster" being pushed into services as iThing users turn to the cloud for AI resources not available on their devices.
