About Stability AI
Stability AI released Stable Diffusion and changed everything: fine-tunes, ControlNets, and a thousand products trace back to its open weights. Stable Diffusion 3.5 remains the strongest fully self-hostable image family, free under community license for most businesses. The company stabilized after 2024 turbulence and keeps shipping across image, video, 3D, and audio. Choose it for control and ownership rather than turnkey polish.
