The Foundation Models framework is a native Swift API that gives you direct access to Apple Foundation Models — on device and in Private Cloud Compute* — as well as any model provider with a Swift package conforming to the Language Model protocol.
From there, multimodal prompts and on-device Vision framework tools let your app reason about images alongside text, while Dynamic Profiles let you swap models, tools, and instructions within a continuous session so your app's intelligence can adapt in real time. Then use the Evaluations framework to ensure your AI features work reliably across dynamic conditions.
