Apple opens its on-device AI model to Claude and Gemini through one Swift API
Foundation Models Framework (macOS)
Apple's Foundation Models framework is a native Swift API that now reaches beyond the on-device Apple Intelligence model to server models like Claude and Gemini, all through the same interface with tool calling and guided generation. It adds image understanding backed by the Vision framework, Dynamic Profiles for swapping models and tools mid-session, an Evaluations framework, an fm CLI in macOS 27, and free Private Cloud Compute access for qualifying small developers.
Dynamic Profiles are designed to be adaptable building blocks: use them to build AI agents, skills, or any other high-level abstraction your app needs.
