Diffusion model
A generative model that **starts from noise and iteratively denoises** into an image (or other signal) guided by a text prompt.
When to use
Understanding how AI image tools (Stable Diffusion, DALL·E, Midjourney-style systems) create pictures from words.
When not to
Text-only chatbots — they use LLMs, not diffusion (unless the product bundles both).
Example
Prompt "watercolor cat on a windowsill" → model removes random noise step-by-step until a coherent image emerges.
