WWDC 2026 - Apple Just Opened the Foundation Models Framework to Any LLM Provider
Apple has opened its on-device Foundation Models framework to third-party LLM providers, allowing developers to integrate various models without altering their existing code. This change, announced at WWDC 2026, enables developers to choose between Apple's on-device model, its private cloud model, custom Swift packages, or HuggingFace's MLX-format models through a unified API. This flexibility allows for a deployment decision based on use case rather than architectural changes, with on-device models suited for focused tasks and cloud models for complex reasoning and long contexts.
