Parameter List
Parameters are options added to a prompt that change how an image generates.
Parameters are always added to the end of a prompt. You can add multiple parameters to each prompt.
Basic Parameters
Aspect Ratios
--aspect, or --ar Change the aspect ratio of a generation.
Chaos
--chaos <number 0β100> Change how varied the results will be. Higher values produce more unusual and unexpected generations.
Fast
--fast override your current setting and run a single job using Fast Mode.
Image Weight
--iw <0β2> Sets image prompt weight relative to text weight. The default value is 1.
No
--no Negative prompting, --no plants would try to remove plants from the image.
Quality
--quality <.25, .5, or 1>, or --q <.25, .5, or 1> How much rendering quality time you want to spend. The default value is 1. Higher values use more GPU minutes; lower values use less.
Relax
--relax override your current setting and run a single job using Relax Mode.
Repeat
--repeat <1β40>, or --r <1β40> Create multiple Jobs from a single prompt. --repeat is useful for quickly rerunning a job multiple times.
Seed
--seed <integer between 0β4294967295> The Midjourney bot uses a seed number to create a field of visual noise, like television static, as a starting point to generate the initial image grids. Seed numbers are generated randomly for each image but can be specified with the --seed or --sameseed parameter. Using the same seed number and prompt will produce similar ending images.
Stop
--stop <integer between 10β100> Use the --stop parameter to finish a Job partway through the process. Stopping a Job at an earlier percentage can create blurrier, less detailed results.
Style
--style <raw> Switch between versions of the Midjourney Model Version 5.1 and 5.2.
--style <4a, 4b, or 4c> Switch between versions of the Midjourney Model Version 4.
--style <cute, expressive, original, or scenic> Switch between versions of the Niji Model Version 5.
Stylize
--stylize <number>, or --s <number> parameter influences how strongly Midjourney's default aesthetic style is applied to Jobs.
Tile
--tile parameter generates images that can be used as repeating tiles to create seamless patterns.
Turbo
--Turbo override your current setting and run a single job using Turbo Mode.
Weird
--Weird <number 0β3000> Explore unusual aesthetics with the experimental --weird parameter.

Model Version Parameters
Midjourney routinely 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.
Version
--version <1, 2, 3, 4, 5, 5.1, or 5.2> or --v <1, 2, 3, 4, 5, 5.1, or 5.2> Use a different version of the Midjourney algorithm.
Legacy Parameters
Some parameters only work with earlier Midjourney Models. Read More about legacy parameters here.

The Midjourney Bot processes jobs on high-end GPUs. Each minute that it takes to complete a job is a GPU minute. You have a limited amount of GPU minutes when in Fast Mode. Because image generations may be processed on multiple GPUs simultaneously, GPU minutes are not directly connected to the time you wait for an image to generate.
