What are U and V in Midjourney

U means Upscaling and V means Variations.

If you want to upscale your image and get a more clear and high-quality image select the U buttons

like the U Button, there is a V button which means variations. You know that Midjourney creates 4 images in a grid but if you don’t like one of them or you like one out of four what you can do is click on the variation and change the image.

Upscaling is not free

You read it right. Upscaling is not free. You have to pay GPU subscription minutes in order to upscale your image to more high quality. So my recommendation is to use this feature when you require a high-quality image like 1024×1024 or 2048×2048.

The main question is upto how much quality we can upscale our image

so let’s understand this from the table given below

Model VersionStarting Grid Images SizeModel Version 4 Default Upscaler
Version 51024×1024
Version 4512×5121024×1024
niji 51024×1024
niji 4512×5121024×1024

As you clearly see that latest version 5 can create a standard image size of 1024×1024. You won’t need to upscale your image. But if you are on version 4 you can generate the standard image size of 512×512 and if you want to upscale your image you can upscale to 1024×1024 in the default Upscaler and if you want upscale into the more high-quality image you can go for beta upscale which can convert your image to 2048×2048.
