Stable Audio is Stability AI's music and audio generation model. The latest version, Stable Audio 2.5, is purpose-built for enterprise-grade sound production with faster generation and more complex musical structures than its predecessor.
Stable Audio 2.5 can generate full tracks up to 3 minutes with multi-part structures including intros, developments, and outros. It uses a latent diffusion architecture - the same technology behind Stable Diffusion for images - to produce rich, detailed audio with complex textures.
Note: Stable Audio 2.5 is a proprietary model. The open-weights variant is Stable Audio Open 1.0, available under the Stability AI Community License. On MeloLab, you can access Stable Audio alongside other models for a complete AI music toolkit.
Stable Audio 2.5 V2 should be evaluated by its real output behavior: how it follows structure prompts, handles vocals or instrumental passages, responds to genre tags, and fits into a repeatable creation workflow. On MeloLab, Stability AI output can be tested beside other models so creators can choose it for songwriting, scoring, and content production when its tone, speed, and control style match the project.
