Midjourney Parameter List



Parameter List

Parameters are options that can be added to a prompt to change how an image generates. These can change an image's aspect ratios, switch between Midjourney Model Versions, change which Upscaler is used, and more. Parameters are always added to the end of a prompt, and multiple parameters can be added to each prompt.

Basic Parameters

Aspect Ratios --aspect or --ar - Change the aspect ratio of a generation.

Chaos --chaos <number 0–100> - Change how varied the results will be. Higher values produce more unusual and unexpected generations.

No --no - Negative prompting; for example, "--no plants" would remove plants from the image.

Quality --quality <.25, .5, 1, or 2>, or --q <.25, .5, 1, or 2> - Determine how much rendering quality time you want to spend. The default value is 1. Higher values cost more and lower values cost less.

Seed --seed <integer between 0–4294967295> - Use a seed number to create a field of visual noise, like television static, as a starting point to generate the initial image grids. Using the same seed number and prompt will produce similar ending images.

Stop --stop <integer between 10–100> - Finish a Job partway through the process. Stopping a Job at an earlier percentage can create blurrier, less detailed results.

Style --style <4a, 4b or 4c> - Switch between versions of the Midjourney Model Version 4.

Stylize --stylize <number>, or --s <number> - Influence how strongly Midjourney's default aesthetic style is applied to Jobs.

Uplight --uplight - Use an alternative "light" upscaler when selecting the U buttons. The upscaled image is less detailed and smoother.

Upbeta --upbeta - Use an alternative beta upscaler when selecting the U buttons. The upscaled image has significantly fewer added details.

Default Values (Model Version 4)

Aspect Ratio Chaos Quality Seed Stop Style Stylize Default Value 1:1 0 1 Random 100 4c 100 Range 1:2–2:1 0–100 .25 .5 or 1 whole numbers 0–4294967295 10–100 4a, 4b, or 4c 0–1000

Default Values (Model Version 5)

Aspect Ratio Chaos Quality Seed Stop Stylize Default Value 1:1 0 1 Random 100 100 Range any 0–100 .25 .5, or 1 whole numbers 0–4294967295 10–100 0–1000

Model Version Parameters

Midjourney releases new model versions to improve efficiency, coherency, and quality. Different models excel at different types of images.

Niji --niji - An alternative model focused on anime-style images.

High Definition --hd - Use an early alternative Model that produces larger, less consistent images. This algorithm may be suitable for abstract and landscape images.

Test --test - Use the Midjourney special test model.

Testp --testp - Use the Midjourney special photography-focused test model.

Version --version <1, 2, 3, 4, or 5> or --v <1, 2, 3, 4, or 5> - Use a different version of the Midjourney algorithm. The current algorithm (V4)
