Apple apps get one door to local models: swap the import, keep the session code, and run system or open-weight models
AnyLanguageModel 1.0 turns Apple's Foundation Models interface into a replaceable layer: an app changes its import from FoundationModels to AnyLanguageModel, and the same session code can call the system model, open-weight models run through llama.cpp, MLX and Core ML, and several hosted providers. Before this, developers curious about local models were unsure how to start and wanted to avoid the added complexity of supporting multiple inference providers. Over the year the library aligned tool calling and guided generation across providers and added image input and Linux support.
