MLX-native port of Supertone's Supertonic 3 multilingual TTS. Runs the full flow-matching + classifier-free-guidance pipeline at ~x100 realtime on Apple Silicon, with audio cosine 1.0 vs the cached MLX path and cosine 0.98 vs the upstream ONNX Runtime reference. Weights are hosted at https://huggingface.co/ambassadia/supertonic-3-mlx and auto-downloaded on first use; this repository ships the port code, the model card, audio samples, and a zero-config setup_and_test.sh. Install: pip install git+https://gitea.tavportal.com/olivier/supertonic-3-mlx.git Quick test: git clone https://gitea.tavportal.com/olivier/supertonic-3-mlx.git cd supertonic-3-mlx && ./setup_and_test.sh Licenses (dual): model weights = BigScience Open RAIL-M (Section 4 propagation), port code = Apache-2.0.
