When Midjourney generates a set of images based on a specific prompt, it assigns a unique number as its seed value. This number will act as a field of visual noise and will be considered the starting point for the initial image grid.
Midjourney Seed – BEST USE! How, Explained AND Examples
The Seed or –seed parameter allows you to create identical images and modify images already created on Midjourney. During generation, you can specify a preferred seed value for the images you are going to create.
When you generate an image grid without assigning a seed value, Midjourney will generate a random seed value for your creation. You can obtain the seed value by querying detailed information about your creation after it has been generated. You can then use this number to recreate images you previously generated or modify them with different parameters.
The ability to produce identical copies of previous generations depends on the Midjourney model you are using for your image generation. You can only produce nearly identical images if you are using Midjourney version 4, 5 and Niji. If you are using older models such as version 1, 2, 3, test and testp, Midjourney can only produce images with similar composition, color and detail, but they are not 100% identical.
