How do generative AI models create new images and videos?

A generative AI model is like a super-smart artist who learns from lots of pictures and videos and then makes new ones on its own.

Imagine you have a big box full of different colored building blocks, red, blue, green, and more. Each block has a shape, and together they can make towers, houses, or even spaceships. A generative AI model is kind of like that box: it learns the shapes and colors from many pictures and videos, and then uses them to build new ones.

First, the AI looks at thousands of images and videos, like watching a movie over and over again. From each one, it notices patterns, like how people walk or how clouds look in the sky. This is like when you learn how to draw by copying pictures many times.

Once it has learned all these patterns, the AI can make new images and videos just by thinking! If you ask it to show you a cat sitting on a chair, it picks out the right "blocks", like the shape of a cat’s head or the texture of fabric, and puts them together in a way that looks real.

It's like having a friend who can draw amazing pictures after watching many others, and then they make up their own!
