Apple now lets third-party developers call its **Foundation Models framework** through a public API, putting the on-device and Private Cloud Compute models behind Apple Intelligence into outside apps for the first time. The beta arrived with this week's Apple developer event and the iOS 27 release cycle, with dedicated session types for system-level and private-cloud inference. Alongside the beta, Apple published developer documentation for natural-language queries over indexed app content and for linking AI agents to Safari.

With the framework, apps can generate text, summarize content, extract named entities, and interpret images, and they can add images to a text prompt. The @Generable macro guides responses into Swift data structures the developer defines, while tool calling lets models reach local databases, web services, or app-specific functions. Open-source models loaded through Core AI share the same interface, so one integration serves Apple models and custom models.

The real test is adoption. Siri AI, the rebuilt agentic assistant Apple introduced in June, reaches consumers this year, but as of early September apps like Gmail and WhatsApp still do not work with the developer beta. Amazon's shopping app launches a search without completing an order. New agent actions require apps to adopt the Foundation Models framework, while older SiriKit task setups keep working.

## Why this matters

Apple is betting its AI strategy on third-party developers. Each app that integrates the Foundation Models framework gives Siri AI another action it can perform, so reluctance from Google, Meta, and Amazon is a real risk: the platform is only as useful as the apps that join it.
