Mattt and the team at Hugging Face have released version 1.0 of AnyLanguageModel, a Swift library that acts as a drop-in replacement for Apple's Foundation Models framework. By changing a single import statement, you can swap between the on-device system model, local runtimes like MLX and llama.cpp, and hosted APIs using identical session code. It also includes support for guided generation, streaming tool calls, and model downloads via companion packages.
If you are already writing Swift apps and want to experiment with local weights or abstract away multiple inference backends without rewriting your session logic, this saves you real boilerplate. The catch is that managing memory for open-weight models on user hardware remains messy, and relying on a third-party wrapper means you are coupling your inference layer directly to Hugging Face's ecosystem.
