Stable Audio 2.0
Text-to-music model generating up to 3-minute structured songs at 44.1kHz stereo.
About
Stable Audio 2.0 was unveiled by Stability AI on April 3, 2024, upgrading the original Stable Audio (September 2023) from 90-second clips to full tracks up to three minutes long with coherent musical structure: intro, progression, and outro. It works from text prompts or uploaded audio, and added audio-to-audio generation for transforming samples with text instructions.
Trained on 800,000+ licensed tracks from AudioSparx (with an opt-out for artists), it was positioned against Suno and Udio with a free tier on the Stable Audio website. Note this is the commercial product, not the open Stable Audio Open release; weights are not publicly available. It launched amid a rocky period for Stability AI, two weeks after CEO Emad Mostaque's resignation.
