WWDC26: What’s new in the Foundation Models framework | Apple
Apple is open-sourcing the Foundation Models framework and adding cloud reasoning models plus third-party model access from Anthropic and Google.
“The Foundation Models framework, including many of the brand new APIs that we're announcing today, is going open source!”
At WWDC, Apple announced major upgrades to its Foundation Models framework: open-sourcing it, a rebuilt on-device model with Vision capabilities, a new cloud-based Private Cloud Compute reasoning model, and a model abstraction layer that lets third-party frontier models from Anthropic and Google plug in via Swift packages. This matters because Apple is shifting from a closed on-device AI stack toward an open, multi-provider ecosystem that brings privacy-preserving cloud reasoning and external LLMs directly into its developer platform.
