New Stability Audio 3.0 Models
Stability AI, the company behind Stable Diffusion, is releasing a new family of audio models called Stability Audio 3.0. The top model can generate professional‑grade music longer than six minutes.
The four models under the Stability Audio 3.0 name are:
| Model | Parameters | Typical Use |
|---|---|---|
| Small SFX | 459 M | On‑device sound generation, up to 2 min |
| Small | 459 M | On‑device music generation, up to 2 min |
| Medium | 1.4 B | Full compositions up to 6 min 20 s |
| Large | 2.7 B | Full compositions up to 6 min 20 s (API / paid self‑hosting) |
Both the medium and large models can maintain musical structure and melodic tone over the full 6 min 20 s length—more than double the duration supported by Stable Audio 2.0 (released in 2024).
- Small SFX, Small, and Medium models: open weights for anyone to use and modify.
- Large model: available only through the API and paid self‑hosting services; companies with revenue over $1 M must obtain an enterprise license.
Availability and Licensing
In 2024, Stability AI released Stable Audio Open, which allowed music generation of up to 47 seconds. The new family of models represents a significant step up from those earlier open versions.
The company states that the latest audio models are built on fully licensed data.
Industry Context
Many companies are advancing music‑generation technology, including:
- Google – Lyria 3 Pro music generation model
- ElevenLabs – New AI‑powered music generation app
Legal battles over data licensing—such as those involving Suno and Udio—highlight the importance of proper licensing and label partnerships for the long‑term viability of these services.
Partnerships and Talent
Last year, Stability AI signed deals with:
- Warner Music Group – Announcement
- Universal Music Group – Announcement
The company is developing a new suite of products for professional musicians. Ethan Kaplan, former chief digital officer at Universal Audio and Fender, is joining Stability AI to lead its professional music offering.
Other AI firms are bolstering their music credentials by hiring industry executives:
- Suno hired former Merlin CEO Jeremy Sirota as chief commercial officer – source
- ElevenLabs appointed Derek Cournoyer (formerly of Kobalt) as strategy lead for its music business – source
