    Article summary

    The current Midjourney and Niji Model Versions produce grids of 1024 x 1024 pixel images. Use the U1 U2 U3 U4 buttons under each image grid to separate your selected image from its grid. You can then use the Upscale (Creative) or Upscale (Subtle) tools to increase the size of your image.

    The Upscale (Subtle) option doubles the size of your image and keeps details very similar to the original. Upscale (Creative) also doubles the size of your image but adds new details to the image. Experiment with each upscaler option to find the one most suitable for the style of your image.


    • Upscale tools use your subscription's GPU minutes. Upscaling can take up to twice as many GPU minutes as generating an initial image grid.
    • Upscale tools are not compatible with the --tile parameter.



    How to Use the Upscale Tools

    1. Generate an Image

    Create an image using the /imagine command.

    2. Select an Image

    Use a U button to separate your selected image from the grid.

    3. Select Upscale

    Click on the Upscale (Subtle) or Upscale (Creative) button to upscale your image. The upscalers will double the size of your image to 2048 x 2048 pixels.

    Upscale Tip

    Upscale jobs you generated before new upscalers were released by refreshing them with the /show command. Buttons for all upscalers compatible with that image will appear under the refreshed job.


    Legacy Upscalers

    Earlier Midjourney model versions generated grids of lower-resolution images. You can use a legacy Midjourney upscaler on these images to increase the size and add additional details. There are multiple legacy upscale models available for upscaling images made with earlier Midjourney models. Using a legacy upscaler uses your subscription's GPU minutes.
