WWDC26: Bring an LLM provider to the Foundation Models framework | Apple
Apple opens its Foundation Models framework to nearly any LLM via a new open-source Language Model protocol.
“Anthropic and Google will soon extend the Foundation Models framework with Swift packages of their own, making state-of-the-art Claude and Gemini models available to all Swift developers.”
At WWDC26, Apple announced that its Foundation Models framework now works with nearly any LLM—local or server-based—through a new public, open-source Language Model protocol, with a rebuilt on-device model plus Private Cloud Compute, Core AI, and MLX options. Anthropic and Google will ship Swift packages bringing Claude and Gemini into the same unified API. This matters because Apple is positioning itself as a neutral integration layer for third-party frontier models across its platforms, lowering the barrier for developers to swap models behind one consistent interface.
