Stability AI

London-based Stability AI became a household name in generative AI as the company behind Stable Diffusion, the open-source image model that helped kick off the text-to-image boom. Its work now spans image, video, audio and 3D content, distributed openly and offered to enterprises via APIs and self-hosted deployment. The open approach built a vast developer community, though the company has also had to navigate the commercial and copyright pressures that come with it. It remains one of the UK's best-known generative-media labs.
