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 company claimed.
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 services) |
Both the medium and large models can maintain musical structure and melodic tone over a 6‑minute‑20‑second composition—more than double the length achievable with Stable Audio 2.0 (released in 2024).
Stability AI is making the small SFX, small, and medium models available with open weights for anyone to use and modify. In 2024 the company released Stable Audio Open, which allowed music generation of up to 47 seconds. The new family of models is a significant step up from those earlier open versions.

Availability and Licensing
- The large model is accessible only through the API and self‑hosting paid services.
- Companies with annual revenue exceeding $1 million must obtain an enterprise license.
Industry Context

Partnerships and Future Plans
Last year Stability AI signed deals with:
The company says its latest audio models are built on fully licensed data. Stability AI is also developing a new suite of products for professional musicians, though details remain scarce. Ethan Kaplan, former chief digital officer at Universal Audio and Fender, has joined to lead Stability’s professional music offering.
Hiring Trends in AI Music
AI firms are bolstering their credibility by hiring music industry executives:
- Suno hired former Merlin CEO Jeremy Sirota as chief commercial officer.
- ElevenLabs appointed Derek Cournoyer (formerly of indie publisher Kobalt) as a strategy lead for its music business.
