Magenta RealTime 2 — Apple Silicon build (for Serenance)

These are the Magenta RealTime 2 model weights by Google DeepMind, converted and quantized for on-device Apple Silicon inference. They are consumed by Serenance, a Mac-native focus-music app by Arign Ltd, which streams them at first run and generates music entirely on the user's Mac.

Modifications by Arign Ltd (2026): the original weights were converted and quantized for on-device Apple Silicon inference (MLX / .mlxfn format, with the MusicCoCa and SpectroStream encoder stacks packaged for local use). No changes were made to the model's behaviour beyond format conversion and quantization for efficiency.
