# Stable Audio Open (stable-audio-tools)

> stable-audio-tools is the code behind Stable Audio Open 1.0 and Open Small, with a basic Gradio UI and training scripts. The model makes instrumental music, loops and sound effects from an English text prompt; its model card says it cannot generate realistic vocals, so it does not write songs. Code is MIT; weights are gated on Hugging Face under the Stability AI Community licence, free for commercial use under USD 1M annual revenue. Hardware and OS support are not documented.

## What it replaces
- Suno: Instrumental tracks (Instrumental mode) (partial). Short instrumental clips and loops only; no vocals or full songs.

## Facts, with sources

| Question | Status | Answer | Source | Checked |
|---|---|---|---|---|
| Runs on my machine? | Confirmed | Yes, Gradio interface and Python scripts on your own machine | https://github.com/Stability-AI/stable-audio-tools#interface | 2026-10-15 |
| Code licence | Confirmed | MIT | https://github.com/Stability-AI/stable-audio-tools/blob/main/LICENSE | 2026-10-15 |
| Model weights licence | Partial | Stability AI Community licence (gated download); free under USD 1M annual revenue | https://huggingface.co/stabilityai/stable-audio-open-1.0 | 2026-10-15 |
| Commercial use | Partial | Yes for individuals and businesses under USD 1M annual revenue; an enterprise licence is needed above that | https://stability.ai/license | 2026-10-15 |
| Paid services needed? | Confirmed | None required below the revenue threshold; a free Hugging Face account is needed to accept the model terms | https://github.com/Stability-AI/stable-audio-tools#interface | 2026-10-15 |
| Hardware | Unknown | Not documented | none found | - |
| Operating systems | Unknown | README documents PyTorch/Python dependencies and GPU training/inference, but no Windows/macOS/Linux support matrix; those dependencies alone do not establish per-OS support | https://github.com/Stability-AI/stable-audio-tools#install | 2026-10-16 |
| Setup effort | Confirmed | Medium; uv sync with PyTorch 2.5+, optional Flash Attention, and accepting the gated model terms | https://github.com/Stability-AI/stable-audio-tools#install | 2026-10-15 |
