We’re excited to share that Stable Audio 3.0—Stability AI’s new family of music models built for artistic experimentation—is coming to ComfyUI. Trained on fully licensed data, these models bring variable-length generation, on-device-friendly small checkpoints, and stronger musicality for longer structure—so you can go from quick SFX to extended tracks inside the workflows you already use.

Model highlights

• Licensed for commercial use — trained on fully licensed music data.
• Flexible clip length — from quick SFX and short loops to longer tracks (up to about two minutes on Small, six minutes on Medium).
• Lightweight, small models — run SFX and short music on a CPU, no big GPU required.
• Medium for longer music — fuller tracks with stronger structure when you have a GPU.

Available Models

• Small-SFX: Sound effects and short ambiance, up to 2:00,
• Small-Music: Short music and on-device-friendly loops, up to 2:00
• Medium: Longer tracks with stronger structure and musicality, up to ~6:20

Small reaches two minutes (vs. 11s / 47s on Stable Audio Open). Medium goes beyond six minutes when you need length.
