Apple launched its Foundation Models framework at WWDC 2025. The new SDK lets developers run Apple’s AI models entirely offline, directly on devices.
Craig Federighi, Apple’s VP of software engineering, showed how apps can use on-device AI from Apple Intelligence to create smart features. For example, Kahoot can build personalized quizzes from your notes — all without cloud API fees or sending data to servers.
Federighi said: 
“For example, if you’re getting ready for an exam, an app like Kahoot can create a personalized quiz from your notes to make studying more engaging.”
“And because it happens using on-device models, this happens without cloud API costs […] We couldn’t be more excited about how developers can build on Apple intelligence to bring you new experiences that are smart, available when you’re offline, and that protect your privacy.”
The Foundation Models framework is native to Swift, Apple’s app programming language. Apple says developers can integrate AI with just three lines of code.
Built-in features include guided generation and tool calling. Automattic is already testing it in the Day One journaling app. Mapping app AllTrails uses it to suggest hiking routes.
The framework is available now to Apple Developer Program members. A public beta drops next month.
