Classifier-Free Guidance (CFG)

Classifier-free guidance (CFG) is how a diffusion model follows a prompt: each step runs the model with and without the prompt and extrapolates the gap.

Diffusion Model

A generative model that learns to undo a fixed noising process — what the network really predicts, why the step count is the cost, and why it displaced GANs.

Generative Adversarial Network (GAN)

Two networks trained against each other: one invents data, the other judges it. The generator never sees a real example — only the judge's verdict.

Image Generation

How AI turns noise into a picture: the diffusion loop, the noise schedule on numbers, why it runs in a 48x-compressed latent space, and what guidance costs.
