Midjourney is a powerful tool that turns text into amazing images. But to really get the most out of it, you need to know about parameters. Parameters are like extra instructions you give Midjourney to control things like image size, style, and more. Let's explore these parameters to help you create exactly what you envision.

Understanding Midjourney Parameters

When you type a prompt, Midjourney uses its default settings. But you can change these settings by adding specific parameters to your prompt. These parameters always go at the end of your prompt and start with two dashes.

[P]For example, if you want a 3:4 image instead of the default square, you'd add --ar 3:4 to your prompt. To use more than one parameter, just separate them with a space.</P]

Key Midjourney Parameters

Version

The version parameter decides which Midjourney model is used to make your images. The latest models can make better and more realistic images. To use a specific model, add --version followed by the model number, like --version 5. Each model has its own unique look, so experimenting with different versions is a great way to see how Midjourney has improved. The latest versions are 7.0 and 7.1 but there are many other versions you can use, such as version 3 by adding --v 3 to your prompt.

Aspect Ratio

Aspect ratio is the width and height of your image. The default is 1:1, which is a square. You can change it by using --ar followed by the ratio. For example, --ar 16:9 creates a widescreen image. Keep in mind there are limits to how wide or tall your images can be.

Chaos

Chaos affects how different the images in your grid are. The default value is 0. If you increase the chaos, you'll get more varied results. Use --chaos followed by a number up to 100. For a little variety, try --chaos 5.

Stylize

Each Midjourney model has a default style. Stylize controls how strong that style is in your images. The default is 100, and the range is 0 to 1000. A higher value gives you more stylized results, but your prompt might be followed less closely. To adjust, use --stylize followed by a number.

Style Reference

Style reference is a great feature that lets you copy the style of other images. When you use style reference, Midjourney looks at things like colors, textures, and overall style and uses them in your images. You can use image URLs or style codes. To use it, add --style reference followed by the image URL or code. Or, add --style reference random to add a random style to your image.

Style Weight

Style weight controls how much the style reference affects your images. The default is 100, and the range is 0 to 1000. A higher number means a stronger influence. For a more subtle effect, try --style weight 15.

Style

Style lets you change Midjourney's default aesthetic. Many people use --style raw to reduce Midjourney's influence and get more realistic images. This parameter has been around since version 5.1. There may be more style modes for different versions of Midjourney.

Quality

[P]Quality controls how much effort Midjourney puts into making your images. The default value is 1. Lower values mean faster images but less detail. Higher values mean slower images but more detail. To change it, add --quality followed by a value. Different Midjourney models accept different quality values. Want to learn more ways to enhance your Midjourney Workflow?

Speed: Turbo, Fast, and Relax

These parameters control how fast your images are made. Turbo and fast use your fast GPU hours. Relaxed mode is slower but doesn't use your fast hours. You can set your default speed in your settings, but you can also override it in your prompt by adding --turbo, --fast, or --relax.

Repeat

Repeat tells Midjourney to run the same prompt more than once. This can only be used with fast or turbo mode. If you want to run a prompt five times, add --repeat 5.

Video

[P]Video creates a short time-lapse of your image being generated. To use it, add --video to your prompt. This parameter works best on Discord. After your image grid is done, react to it with the envelope emoji to get a direct message with a link to the video.

Stop

Stop lets you end image generation early. It takes values between 10 and 100. For example, adding --stop 50 stops the process at 50%. This can be useful for softer, more abstract images.

Image Weight

[P]Image weight can only be used with image prompts. It controls how much the images influence your results. The default value is 1. In Midjourney V6, it takes values between 0 and 3. To use it, add --image weight followed by the value. This is one of the best kept secrets to achieve unique visions in Midjourney.

Character Reference

[P]Character reference is similar to style reference, but it tries to match the character in your reference image. To use it, type your prompt, then add --character reference and paste the URL of your character reference image. You can also drag and drop the image, but select the character icon.

Character Weight

Character weight controls how closely Midjourney follows the clothing and hairstyle of your reference character. The default is 100, and the range is 0 to 100. When character weight is 100, Midjourney focuses on the face and clothing. When it's 0, it only focuses on the face.

Personalize

[P]Personalization lets you create your own custom Midjourney model. To use it, you first need to teach Midjourney about your style. Then, include --personalize in your prompt. When enabled, your personalized model will override the default Midjourney style. The stylize parameter then controls the strength of your personalized style.</P]

No

No tells Midjourney what you don't want in your image. Add --no followed by what you want to exclude. If there are multiple things, separate them with commas. For example, --no trees, buildings will remove trees and buildings from the image.

Tile

Tile is perfect for creating repeating patterns. Just add --tile to your prompt. The resulting images can be tiled to create a seamless pattern. Be sure to use version 6.1 or higher when upscaling your tile results.

Seed

Each Midjourney job starts with a canvas of visual noise linked to a seed number. If you want to use a specific seed number, use the seed parameter. For example, --seed 1111. This is useful for testing how parameter values affect results.

Weird

Weird creates strange and unexpected results. The default value is 0, and it takes values up to 3000. Higher values create more unusual images. Try using --weird 1, 3, or 5 to add some interest to your images.

Conclusion

[P]Midjourney parameters are your key to creating amazing and specific images. By understanding and using these parameters, you can control almost every aspect of your creations. Don't be afraid to experiment and see what you can create!</P]
