Diffusion Model
The technique behind most AI image generators — it starts with random noise and gradually refines it into a coherent image matching your prompt.
01 Definition
A diffusion model generates images by starting with pure visual noise (like TV static) and running many steps that gradually remove the noise in a way guided by your text prompt, until a coherent image emerges.
02 Why It Matters
This is the core technology behind Midjourney, DALL·E, and Stable Diffusion — knowing it exists helps explain why image generators sometimes produce strange artifacts (the 'denoising' process going slightly wrong).
03 Example
Midjourney and Stable Diffusion are both built on diffusion models.
