Stability AI, the company behind Stable Diffusion, is releasing a new family of audio models, called Stability Audio 3.0. The flagship model can create professional-quality music lasting more than six minutes, the company claimed.
The company is releasing four new models under the name Stable Audio 3.0: small SFX (459M parameters), small (459M parameters), medium (1.4B parameters) and large (2.7B parameters). The duo of small models are suitable for producing audio and music on the device for up to two minutes.
Both the medium and large models can create full 6 minute 20 second compositions that can maintain musical structure and melodic tone. That’s more than double what Stable Audio 2.0, released in 2024, could produce.
Stability AI makes small SFX, small and medium models with open weights available for anyone to use and modify. In 2024, the company released Stable Audio Open, which allowed the creation of music up to 47 seconds long. The new model family is a big step forward from the previous open versions.
The large model is only available through the API and paid self-hosting services. Additionally, companies with more than $1 million in revenue will need to obtain a business license.
Many companies, including Google and ElevenLabs, are releasing models and tools around music creation. However, as Suno and Audio Ongoing court battles have proven that data licensing and label partnerships could be a key part of these services’ long-term survival.
Last year, Stability AI signed deals with Warner Music Group and Universal Music Group for the development of music creation models and tools. The company said its latest line of audio models is based on fully licensed data.
The AI startup is developing a new suite of products for professional musicians, but did not elaborate on its features. Ethan Kaplan, former chief digital officer of Universal Audio and Fender, joins the company to lead Stability’s professional music offering.
Some AI companies are trying to boost their credentials by hiring music executives. Earlier this year, Suno hired former Merlin CEO Jeremy Sirota as chief commercial officer. ElevenLabs has also hired Derek Cournoyer from indie music publisher Kobalt as leadership strategy for her music business.
