Video generation has also been added to it…

Stable Diffusion is the open-source foundation of the AI image world. Unlike closed tools such as Midjourney or DALL·E, its models are free to download and run on your own hardware — which means no subscription, no content filters you can't adjust, no per-image cost, and total privacy. Your prompts and images never leave your machine.

The open ecosystem is its superpower: thousands of community fine-tuned models and LoRAs (downloadable styles and characters, shared on hubs like Civitai), ControlNet for precise pose and composition control, inpainting/outpainting, upscaling, and interfaces from beginner-friendly apps to the node-based ComfyUI used in professional pipelines.
