# Midjourney Parameters

[Aspect Ratios](https://docs.midjourney.com/aspect-ratios)

\--aspect, or --ar Change the aspect ratio of a generation.

&#x20;

[Chaos](https://docs.midjourney.com/chaos)

&#x20;\--chaos \<number 0–100> Change how varied the results will be. Higher values produce more unusual and unexpected generations.

&#x20;

[No](https://docs.midjourney.com/multi-prompts)

&#x20;\--no Negative prompting, --no plants would try to remove plants from the image.

&#x20;

[Quality](https://docs.midjourney.com/quality)

&#x20;\--quality <.25, .5, 1, or 2>, or --q <.25, .5, 1, or 2> How much rendering quality time you want to spend. The default value is 1. Higher values cost more and lower values cost less.

&#x20;

[Repeat](https://docs.midjourney.com/repeat)

&#x20;\--repeat <1–40>, or --r <1–40> Create multiple Jobs from a single prompt. --repeat is useful for quickly rerunning a job multiple times.

&#x20;

[Seed](https://docs.midjourney.com/seeds)

&#x20;\--seed \<integer between 0–4294967295> 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.

&#x20;

[Stop](https://docs.midjourney.com/stop)

&#x20;\--stop \<integer between 10–100> 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.

&#x20;

[Style](https://docs.midjourney.com/models)

\--style <4a, 4b, or 4c> Switch between versions of the Midjourney [Model Version ](https://docs.midjourney.com/docs/models)4

\--style \<expressive, or cute> Switch between versions of the Niji [Model Version ](https://docs.midjourney.com/docs/models)5

&#x20;

[Stylize](https://docs.midjourney.com/stylize)

&#x20;\--stylize \<number>, or --s \<number> parameter inﬂuences how strongly Midjourney's default aesthetic style is applied to Jobs.\\

[Uplight](https://docs.midjourney.com/upscalers)

&#x20;\--uplight Use an alternative "light" upscaler when selecting the U buttons. The results are closer to the original grid image. The upscaled image is less detailed and smoother.

&#x20;

[Upbeta](https://docs.midjourney.com/upscalers)

&#x20;\--upbeta Use an alternative beta upscaler when selecting the U buttons. The results are closer to the original grid image. The upscaled image has signiﬁcantly fewer added details.

&#x20;Midjourney routinely releases new model versions to improve efﬁciency, coherency, and quality. Different models excel at different types of images.

&#x20;

[Niji](https://docs.midjourney.com/models)

&#x20;\--niji An alternative model focused on anime style images.

&#x20;

[High Deﬁnition](https://docs.midjourney.com/models)

&#x20;\--hd Use an early alternative [Model ](https://docs.midjourney.com/models)that produces larger, less consistent images. This algorithm may be suitable for abstract and landscape images.

&#x20;

[Test](https://docs.midjourney.com/models)

&#x20;\--test Use the Midjourney special test model.

&#x20;\
[Testp](https://docs.midjourney.com/models)

&#x20;\--testp Use the Midjourney special photography-focused test model. [Version](https://docs.midjourney.com/models)

\\

\--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) is the default setting.
