Weights: Not released
API: Yes
Commercial use: Permitted subject to conditions

It generates variable-length music from text with per-second granularity, with a documented family maximum of around six minutes. Available through the Stability AI API and enterprise self-hosting, and on partner platforms including ComfyUI.

Commercial use — Permitted subject to conditions

Stability markets the whole 3.0 family as 'trained on fully licensed data' and 'commercially safe', with 'legal indemnification provided under our Enterprise license'.

Revenue threshold: free below $1,000,000 in annual revenue, chargeable above it.

Free only below a revenue threshold. The Enterprise License covers organisations with $1M+ annual revenue
Commercial route is enterprise sales. The Enterprise License covers organisations with $1M+ annual revenue

The conditions above were extracted from the licence notes recorded during research, and each one shows the sentence it came from so you can check the reading. Read the licence before you rely on any of this. Nothing on this page is legal advice, and this site does not tell you a model is cleared for commercial use.

Strengths

Fully licensed training data with enterprise indemnification available
Variable-length generation with per-second granularity
Long-form output for the category (around six minutes)
Self-hostable for enterprises with data-residency needs

Weaknesses

No published API price could be retrieved
Closed weights unlike the Medium and Small siblings
Sample rate not documented on the pages fetched
Vocal capability not clearly documented for 3.0 Large

Best for

Studios and platforms needing indemnified, clearance-safe music at volume
Long-form beds and sound design where provenance matters

Where the sources disagree

Recorded rather than resolved. Picking the tidier number would hide the fact that the vendor's own pages do not agree.

The news index lists the Stable Audio 3.0 post as 5/20/26 (20 May 2026) but the post body as parsed rendered the date as May 20, 2024; the index date is used here.
Maximum duration: stability.ai/stable-audio says 'up to six minutes' for the family, while the 3.0 announcement attributes 'up to 6:20' to Medium and 'over 6 minutes' to Medium/Large. No unambiguous number for Large, so null.

What to understand before using it

Explainers naming the mechanisms this model's own documentation mentions.

Training data and copyright: what is not settled names “indemnification”
Open weights versus closed API: renting or owning the model names “weights”
Diffusion models: generation by denoising names “sample”

Shotcraft hosts no sample output. Judging a model means watching its own showreel with your own eyes, and a clip re-hosted here would be a clip we chose.
