How to Batch Many Variations with Permutation Prompts in Midjourney

Use curly-brace permutation syntax to fire off dozens of prompt variations from one command.

When you are exploring options, running prompts one at a time is slow. Permutation prompts let you list alternatives inside curly braces, and Midjourney expands them into every combination automatically. One command can launch a whole exploration grid, which is a huge time saver for moodboards and A/B comparisons.

What you need

An active subscription, ideally on a Standard or Pro plan for the generation volume
A base prompt with one or two things you want to vary
Awareness that each combination costs a separate generation

Step 1: Identify what to vary

Pick the parts of your prompt you are unsure about, such as the medium, the time of day, or the aspect ratio. Each set of options becomes one curly-brace group.

Step 2: Write the permutation with curly braces

Put the options inside curly braces, separated by commas. Midjourney creates one prompt per combination. Two groups of three options produce nine prompts, so the count multiplies quickly.

permutation prompt

/imagine prompt: a fox in a forest, {watercolor, oil painting, 3d render} style, {at dawn, at night} --ar 3:2

That single line expands into six prompts: three styles times two times of day.

Step 3: Confirm the batch

Because permutations can launch many jobs, Midjourney shows a confirmation message with the total count. Click the green check to proceed or the red cross to cancel if the number is higher than you expected.

Always check the count before approving.

Step 4: Permute parameters too

Curly braces work on parameters, not just words. You can sweep aspect ratios or stylize values to compare them side by side in one launch.

/imagine prompt: a minimalist poster of a mountain --ar {1:1, 3:4, 16:9} --stylize {50, 250}

Watch your generation budget

Permutations spend fast hours per combination. A three-by-three-by-two permutation is eighteen grids. In Relax mode this is free but slow, so run large sweeps in Relax to avoid burning Fast hours.

Step 5: Compare and pick winners

As the grids stream in, scan them as a contact sheet. Note which style and setting combinations work, then re-run just the winner at higher quality or with refinements.

Result: in one command you produced a structured comparison of styles and moods, letting you make a design decision in minutes instead of dozens of manual prompts.
