What is Stable Diffusion?

How it works

Stable Diffusion is a landmark open-source AI model that democratized AI image generation. It uses latent diffusion to generate images from text prompts and has spawned a massive ecosystem of fine-tuned models, LoRAs, ControlNets, and tools. While Stable Diffusion itself is an image model, its architecture and techniques have influenced video generation models including LTX Video. Understanding Stable Diffusion concepts (checkpoints, LoRAs, ControlNet, CFG scale, sampling methods) provides a foundation for understanding most AI generation tools, even proprietary ones that do not expose these parameters directly.
