Stable Audio 3.0, the model family built with open-weight models

Open for experimentation, with ownership of what you createAll Stable Audio 3.0 models are trained on fully licensed data. Under the Stability AI Community License, you own your outputs and can distribute and commercialize them freely.For organizations with more than $1M in annual revenue, you can get commercial coverage with our Enterprise license. We also offer legal indemnification under the Enterprise license.3.0 Small SFX, 3.0 Small, and 3.0 Medium are all open-weights. To our knowledge, other open music models either restrict commercial use or carry the risks associated with being trained on unlicensed music.Architectural advancements for variation and iterationStable Audio 3.0 is our next-gen architecture, built with a novel semantic-acoustic autoencoder that enables longer, more flexible audio generation. You can read the full research paper here.Variable-length generation, up to more than six minutes. Stable Audio 3.0 introduces a new method for variable-length audio generation that enables you to generate exactly what you need, at per-second granularity. 3.0 Small generates up to two minutes, compared to 11 seconds from Stable Audio Open Small, and 47 seconds from Stable Audio Open. 3.0 Medium and 3.0 Large generate more than six minutes.Full music composition on-device. To our knowledge, 3.0 Small is the only model capable of full music composition on-device. For the first time, on-device and offline audio generation isn’t limited to short samples; it can produce complete musical tracks.Customize the models on your own library with support for LoRa training. A LoRa is an efficient method for fine-tuning that was first made popular in image generation, and is now an emerging method for customizing audio generation models.For the first time we’re publishing documentation for LoRa training, alongside the weights for 3.0 Small and 3.0 Medium. For organizations with our Enterprise license, we offer the option of white-glove support with fine-tuning.Audio inpainting options. Modify a segment of a track, rework part of a song, or extend your composition without starting over. Stable Audio 3.0 supports single-segment editing, multi-segment editing, and causal continuation (extending audio beyond its original endpoint).Setting the stage for what’s nextStable Audio 3.0 is the new architecture on which we’re already building our next generation of fully licensed audio models for professionals. While responsibly trained generative AI models are critical, they are not enough on their own. Artist-centric AI will only win if the product experience on a licensed platform is better than the experience on an unlicensed platform. We’re also working on a suite of new products for musicians.
