What is Stable Audio?
Stable Audio is Stability AI's generative audio tool: it creates instrumental tracks and sound effects from a text description. Version 3.0 (May 2026) reaches up to 6 minutes 20 seconds per composition, and its Stable Audio Open models are open-weight, so you can run them free on your own machine if you have a GPU. It is trained on licensed music, which makes it safe for commercial use.
