Every image you generate on Stable Diffusion is assigned a random number called a seed. It’s really nothing more than a random number that identifies that particular image.
For the most part, this doesn’t matter, but what if you love the way a particular generation looks and want to recreate it with just a few tiny changes? Well, that’s when knowing the seed number of your image matters.
Let’s say you create this great image of Caprice Jane.
But you wished her top was a little different color. That’s where the seed number comes in. It lets you create a similar image with just minor changes to your prompt.
You can also make bigger changes, like making her hair pink. The seed number will help keep the style of the image you want while still allowing you to make some changes.
You don’t need to use seed numbers when creating random images. You really only need the seed number when you are trying to duplicate your past work or the work of others.
