Diffusion model

← All terms · Image, video, audio AI

A class of AI models that generate images, video, or audio by taking random digital noise and gradually refining it into a clear, structured output based on a prompt.

What it is

Diffusion models (like Stable Diffusion or Midjourney) are trained by taking clear images, systematically destroying them by adding static noise, and learning how to reverse the process. During generation, the model starts with pure static and iteratively denoises it, guided by text descriptions, until a coherent image emerges.

When you would use it

You refer to diffusion models when discussing the underlying architecture powering modern generative visual and audio AI tools.
