Audio8-TTS-MLX-8bit

Native MLX 8-bit release of Audio8/Audio8-TTS-Preview-0.6b for Apple Silicon.

Inference code, installation, API documentation, tests, and benchmark evidence: vanch007/mlx-audio8-tts.

Artifact

—Affine 8-bit, group size 64, sensitive-bf16 policy.
—827 MiB language-model weights; 2.08 GiB complete repository download.
—The shared 1.26 GiB neural codec, embeddings, and Fast AR depth decoder are kept at higher precision to protect speech quality.
—44,100 Hz output, 10 acoustic codebooks.

M3 Max benchmark

Seeded post-warm-up RTF on the release checkpoint: 0.983 English, 0.922 Chinese, and 0.793 Cantonese. Model download, loading, and warm-up are excluded. Lower is better; values below 1.0 are faster than real-time. The reproducible script and report are published with the source project.

Usage

bash

git clone https://github.com/vanch007/mlx-audio8-tts.git
