About Stable Diffusion (Stability AI)

Stable Diffusion is the open-source family of image, video, and 3D models from Stability AI that powers half the AI imagery on the internet. SD3 fixed the spelling problem — 95% text accuracy — and added strong prompt adherence. The real superpower is local deployment: with an 8GB+ NVIDIA GPU you generate unlimited images at zero per-image cost. For cloud users, the platform.stability.ai API charges roughly $0.01–$0.03 per image, and DreamStudio offers a non-technical web UI on top of the same models.
