How do AI-powered image generators like Midjourney work?

AI-powered image generators like Midjourney work by learning from lots of pictures and then creating new ones based on what they’ve learned.

Imagine you have a robot friend who loves to draw. This robot doesn’t know how to draw at first, but it looks at thousands of drawings, like the way your mom draws stick figures or the way you color in your coloring books. It notices patterns, like how circles can be faces and lines can be trees.

The robot uses numbers to understand pictures. Each picture is turned into a list of numbers that describe colors, shapes, and positions, like how your backpack has different pockets with specific items in them. The more pictures it sees, the better it gets at turning these number lists into new drawings.

When you give it a command like “a dragon flying over a rainbow,” it uses its learned knowledge to create something that matches your description. It’s not magic, it's just really smart guessing, based on what it has seen before.
