Model Version 4 (Legacy)
The Midjourney V4 model is an entirely new codebase and brand-new AI architecture designed by Midjourney and trained on the new Midjourney AI supercluster. The latest Midjourney model has more knowledge of creatures, places, objects, and more. It's much better at getting small details right and can handle complex prompts with multiple characters or objects. The Version 4 model supports advanced functionality like image prompting and multi-prompts.
This model has very high Coherency and excels with Image Prompts.
Version 4 Styles 4a, 4b, and 4c
Midjourney Model Version 4 has three slightly different "flavors" with slight tweaks to the stylistic tuning of the model. Experiment with these versions by adding --style 4a, --style 4b, or --style 4c to the end of a V4 prompt.
--v 4 --style 4c is the current default and does not need to be added to the end of a prompt.
Note on Style 4a and 4b
--style 4a and --style 4b only support 1:1, 2:3, and 3:2 aspect ratios.
--style 4c support aspect ratios up to 1:2 or 2:1.

Niji Model 4 (Legacy)
The niji 4 model is a collaboration between Midjourney and Spellbrush tuned to produce anime and illustrative styles. The --niji 4 model has vastly more knowledge of anime, anime styles, and anime aesthetics. It's excellent at dynamic and action shots and character-focused compositions in general.

V4 Upscaler Tools
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.

Model Version 4 Upscaler
The Midjourney Model Version 4 upscaler increases image size while smoothing or refining details. Some small elements may change between the initial grid image and the finished upscale.
