Stable Diffusion
by Stability AI model
The open-weight image model that made local generation mainstream, and still the one most self-hosted pipelines and fine-tunes are built on. Stability's current generation is Stable Diffusion 3.5, in Large (highest quality and prompt adherence), Turbo (faster) and Medium (balancing quality against customisation) variants, with SDXL and SDXL Turbo still available. Stability also offers hosted editing services — erase, inpaint, outpaint, background removal, recolour and upscale. The reason to choose it over a hosted frontier model is unchanged: these are weights you can download, fine-tune and run yourself.
