Guide to Midjourney's --chaos: Introduce More Randomness

The --chaos parameter (command) in Midjourney affects how crazy and varied your initial image variations are.

• High --chaos values will produce crazier and more varied results (that are also less repeatable).
• Lower --chaos values have more consistent, reliable, repeatable results.
• --chaos has a range between 0-100, and the default --chaos value is 0.
• You can use --chaos, or the short version --c.
• --chaos also works in Niji Mode.

--weird is a similar command that will increase the weirdness of all 4 initial images at once. Don't confuse this command with --stylize either, which increases the power of Midjourney's default look.

You can see how much randomness --chaos introduces to the image. It not only changes up the art style, but sometimes excludes subjects completely.

It will have an effect on:

• Composition
• Medium
• Perspective
• Colors
• Characters

Examples

--chaos 0

A low --chaos value produces images that are not too different from each other. After you've done a single generation, you know what to expect:

--chaos 50

Here's the same prompt, with chaos increased to --c 50.

--chaos 100

And here's chaos to the max value of --c 100:

What's the best chaos value?

This is subjective, but I believe the sweet spot for chaos value is between 2-10. A little chaos goes a long way. Even --c 1 in enough to spice your images up.

--c 2

--c 5

--c 10

At a certain point, you hit diminishing returns. Keeping your --chaos value lower gives you all the variation you need while maintaining quality and cohesion.

Though if you're trying to get as many random ideas as possible, definitely crank that chaos value up!
