Stable Audio Open 1.0 is an open-weights text-to-audio model by Stability AI with approximately 1.21 billion parameters, built on a latent diffusion architecture with DiT components and T5-based text conditioning. It generates variable-length stereo audio of up to 47 seconds at 44.1 kHz. The model was trained exclusively on Creative Commons-licensed audio data (Freesound and Free Music Archive) and is primarily intended for research, sound design, and non-commercial use. Vocal or speech generation is explicitly not supported by the model.
