Stable Audio

Stable Audio is Stability AI's generative audio product, built on the Stable Audio 3.0 model family and trained on fully licensed data. From a text prompt it produces music compositions and sound effects at any length from one second to six minutes, and it can edit what it makes: audio to audio transformation, inpainting to change a segment, and extension to lengthen a track. The web app adds conversational controls and an experimental stems feature. It is aimed at creators and producers who want production quality audio quickly, and at enterprises and developers who need a model they can license or run themselves. The 3.0 family ships in several sizes: Large for enterprise deployments, Medium for full song composition with open weights, and Small and Small SFX tuned for mobile devices, also with open weights. Stability publishes the models through an Enterprise License, the Stability AI API (pay per generation with bulk discounts), open downloads and the stableaudio.com web app, and offers model customization on a customer's own library. Enterprise customers receive legal indemnification. The web app is sold as monthly credit subscriptions: Solo at $12 per month for 660 credits, Session at $30 for 1,800 credits, Producer at $90 for 6,000 credits, and Studio at $199 for 14,000 credits. Unused credits do not roll over. Companies with annual revenue above $1 million are directed to the enterprise team for custom terms, and API usage is priced per generation rather than by plan.
