| # 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](https://serenance.app), 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. |
