+
+Native MLX affine 6-bit weights for
+[`MiniMaxAI/MiniMax-Music3`](https://huggingface.co/MiniMaxAI/MiniMax-Music3),
+converted for lyric-conditioned song generation on Apple Silicon with
+[`mlx-audio`](https://github.com/Blaizzy/mlx-audio).
+
+> Community conversion, not an official MiniMax release. All model credit goes
+> to MiniMax. Review the original model card and license before use.
+
+Other MLX variants:
+[`BF16`](https://huggingface.co/mlx-community/MiniMax-Music3-bf16)
+· [`8-bit`](https://huggingface.co/mlx-community/MiniMax-Music3-8bit)

+
+## Install
+
+MiniMax Music 3 support is proposed in
+[`Blaizzy/mlx-audio#888`](https://github.com/Blaizzy/mlx-audio/pull/888).
+Until that PR is released, install the tested commit directly:
+
+```bash
+python -m pip install "mlx-audio @ git+https://github.com/pinglin/mlx-audio.git@c2fa486ddf98ea8268c227b6d624b2f9ba00dbab"
+```
+
+## Generate
+
+```bash
+python -m mlx_audio.music.generate \
+  --model mlx-community/MiniMax-Music3-6bit \
+  --caption "Warm acoustic pop, 96 BPM, intimate female vocal" \
+  --lyrics $'[verse]\nMorning light across the room\n[chorus]\nSing with me' \
+  --duration 30 \
+  --steps 30 \
+  --seed 7 \
+  --output song.wav
+```
+
+```python
+from mlx_audio.music import load
+
+model = load("mlx-community/MiniMax-Music3-6bit")
+result = next(
+    model.generate(
+        text="Warm acoustic pop, 96 BPM, intimate female vocal",
+        lyrics="[verse]\nMorning light across the room\n[chorus]\nSing with me",
+        duration=30,
+        steps=30,
+        seed=7,
+    )
+)
+print(result.audio.shape, result.sample_rate)  # stereo, 44100 Hz
+```
+
+Lyrics are required by the checkpoint contract. Use `[instrumental]` explicitly
+for instrumental generation. Duration is a requested upper bound: the
+autoregressive stage may emit its end token early. Style, tempo, instrument, and
+vocal controls are probabilistic rather than strict.
+
+## Quantization and verification
+
+- Affine 6-bit weight quantization with group size 64.
+- Large linears in the global language model, RVQ depth decoder, and flow
+  transformer are quantized. Embeddings, output heads, convolutions, condition
+  encoder, and vocoder remain dense for fidelity.
+- The three weight shards total 11,683,414,161 bytes.
+- Strict loading and real generation produced finite 44.1 kHz stereo audio.
+- The mlx-audio regression suite passed 1,738 tests with 34 expected skips; the
+  focused music, converter, and registry suite passed 43 tests and 3 subtests.
+
+Converted with `mlx-audio` 0.4.8 development commit `c2fa486` and MLX 0.31.2.
+
+## License
+
+The weights remain subject to the
+[`MiniMax-Music3 Community License`](https://huggingface.co/MiniMaxAI/MiniMax-Music3/blob/main/LICENSE),
+including its acceptable-use and commercial terms. The full license text is
+included in this repository.
