Its portfolio includes Stable Diffusion 3.5 (text-to-image generation), Stable Audio 2.5 (music and audio synthesis), and Stable Video 3D (3D object creation from images or video). The company distributes models via API, web interfaces, and self-hosted deployments for artists, musicians, game developers, and enterprises. Stability AI has raised $250 million in total funding, including a Series B in August 2026 led by Sony Music and Universal Music, and operates as a private company with 151–200 employees.
Stability AI holds significant structural leverage in creative AI infrastructure: Stable Diffusion's open-source release (August 2022) exceeded 350 million downloads and democratized image generation; the company's audio and video models address expanding adjacent verticals in content creation. The August 2026 Series B backing from major entertainment companies (Sony Music, Universal Music) signals capital confidence and institutional alignment in foundation models for creative workflows, anchoring Stability AI as a recognized vendor in the generative AI ecosystem.
