Stable Audio 3 Small SFX — mirror for mlx-serve
Powered by Stability AI.
This is an unmodified, ungated mirror of
stabilityai/stable-audio-3-small-sfx,
made so mlx-serve can download it without a
Hugging Face token or a gate-acceptance step. No weights, configs or tokenizer files were
changed. All credit for the model goes to Stability AI; this mirror is
not affiliated with or endorsed by them.

Use with mlx-serve
mlx-serve is a native Apple Silicon server (no Python) with OpenAI/Anthropic/Ollama-compatible APIs and local media generation. Website and source: https://github.com/ddalcu/mlx-serve
mlx-serve pull ddalcu/Stable-Audio-3-Small-SFX-MLX-Serve
mlx-serve serve --model-dir ~/.mlx-serve/models
curl http://localhost:8080/v1/audio/sound-generations \
-H 'Content-Type: application/json' \
-d '{"model":"Stable-Audio-3-Small-SFX-MLX-Serve","prompt":"chugging train coming into station with horn","duration_seconds":7}' \
-o train.wav
The mlx-serve app also lists it under Sound Effects. Generates up to two minutes of 44.1 kHz stereo audio in about a second on Apple Silicon.
Using the original tooling
The files are laid out exactly as in Stability's repo, so the official
stable-audio-3 and
stable-audio-tools libraries read them
unchanged.
