GAN

Also known as: Generative Adversarial Network

GAN stands for generative adversarial network: a generator and a discriminator trained in competition.

What GAN is

GANs produced the first photoreal synthetic images and remain useful for fast single-step generation.

How it works

The generator tries to fool the discriminator while the discriminator learns to detect fakes.

Why it matters

It dominated image generation before diffusion models took over.
