ELI5: Explain Like I'm 5

stable diffusion

Stable diffusion is like a game of hot potato! The molecules or particles in a substance are constantly moving around in different directions, just like hot potatoes would move around if a bunch of people were playing the game. This movement is called diffusion, and when it happens in a stable way, it's called stable diffusion. It helps to mix different substances together or move molecules around in a substance to make it more even.
