Call Gemini models directly from the Foundation Models framework
At WWDC, Apple announced that it’s opening its Foundation Models framework to third-party cloud model providers. Starting with iOS 27, macOS 27, iPadOS 27, visionOS 27 and watchOS 27, model providers can implement the new public LanguageModel protocol to provide a common interface for model inference. We’ve made Gemini models available to the Foundation Models framework through the Firebase Apple SDK.
This provides a fully native development experience — cloud-hosted Gemini models can plug directly into the Foundation Models framework using the same API. That means the on-device Apple model and cloud-hosted Gemini models sit behind a shared API surface, so you can easily swap between local and cloud inference to fit your use case. This flexibility is crucial for enabling optimal agentic app experiences while minimizing costs and reducing latency.
