Stability AI, the company behind Stable Diffusion, releases a new audio model family called Stability Audio 3.0. The company claims its top-of-the-line model can generate over six minutes of professional music.
The company will release four new models under the name Stable Audio 3.0: small SFX (459 million parameters), small (459 million parameters), medium (140 million parameters), and large (270 million parameters). The two smaller models are suitable for on-device sound and music generation for up to 2 minutes.
Both medium and large models allow you to create complete 6 minute 20 second pieces that maintain musical structure and melodic tone. This is more than twice the length that Stable Audio 2.0, released in 2024, can produce.
Stability AI creates small SFX, small and medium models with open weights that anyone can use and modify. In 2024, the company released Stable Audio Open, which allows for up to 47 seconds of music generation. The new model family is a significant improvement over the previous open version.
Large models are available only through API and self-hosted paid services. In addition, businesses with revenue over $1 million must obtain an enterprise license.
Many companies, including Google and Celebrities, have released models and tools for music generation. But as Suno and Udio’s ongoing legal battles prove, data licensing and partnerships with music labels could be a key part of the long-term survival of these services.
Last year, Stability AI signed a deal with Warner Music Group and Universal Music Group to develop models and music creation tools. The company said its latest audio model set is built entirely on licensed data.
The AI startup is developing a new suite of products for professional musicians, but declined to provide details on its features. Ethan Kaplan, former chief digital officer at Universal Audio and Fender, will join the company to lead Stability’s professional music offerings.
Many AI companies are looking to hire music executives to beef up their credentials. Earlier this year, Suno hired former Merlin CEO Jeremy Sirota as chief commercial officer. ElevenLab also hired Derek Cournoyer from indie music publisher Cobalt as head of music business strategy.
