/imagine command gives you the facility to generate high-quality images by writing some description or prompt.

I am going to explain it to you in simple steps

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.

The U1 button means upscaling the first image in a grid.
You know that Midjourney creates 4 images in a grid and if you want to upscale it into more detail. You can select the U1, U2,U3 and U4 depending upon which image you want to upscale.
Let’s suppose you want to upscale the last image, you can select U4 and your last image will be upgraded. Basically what Upscaler do is create a more detailed image from the previous one.

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 Version | Starting Grid Images Size | Model Version 4 Default Upscaler |
| Version 5 | 1024×1024 | |
| Version 4 | 512×512 | 1024×1024 |
| niji 5 | 1024×1024 | |
| niji 4 | 512×512 | 1024×1024 |
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.
