Stable Audio Open Small

The Stable Audio Open Small checkpoint is published by Stability AI for text-to-audio. Its weights are available under Stability AI Community License; that alone does not establish that its code and all components are open source.

When to consider it

Consider this audio checkpoint for short sound effects; the card describes output up to 11 seconds at 44.1 kHz.

Check before choosing

A local hardware minimum has not been reviewed, and the Community License requires reading its terms before use.
