Earlier Midjourney model versions start by generating a grid of low-resolution image options for each Job. You can use a Midjourney upscaler on any of these images to increase the size and add additional details. There are multiple upscale models available for upscaling an image. Using an upscaler uses your subscription's GPU minutes.
The U1 U2 U3 U4 buttons under each image grid are used to upscale the selected image.
