What is Stable Diffusion?

Stable Diffusion remains the go-to open-source AI image generator in 2026, now at SD3.5 with improved hands, text rendering, and composition. Unlike cloud-only tools, Stable Diffusion runs on your own hardware — completely free and unlimited with a capable GPU. The DreamStudio web interface provides cloud access, while Automatic1111 and ComfyUI desktop apps offer professional control. Fine-tuned community models (LoRAs) enable infinite style customization.
