The –repeat Parameter in MidJourney: Introduction and Usage Guide

The --repeat parameter in MidJourney is used to generate multiple outputs of the same prompt. It allows users to specify how many times a particular prompt should be repeated, making it especially useful for batch image generation, testing consistency, or exploring variations in randomness.

Functionality of --repeat

  1. Run the Same Prompt Multiple Times
    When the --repeat parameter is used, MidJourney will repeatedly generate images based on the same prompt. This eliminates the need to manually input the same prompt multiple times.
  2. Explore Random Variations
    Even with the same prompt, MidJourney introduces slight randomness in the results. Using --repeat allows users to observe and select from different variations in the generated images.
  3. Increase Efficiency
    For projects requiring multiple images of a similar style, --repeat saves time by automating repetitive operations.

How to Use --repeat

The basic syntax for the --repeat parameter is as follows:

/prompt [description] --repeat <number>

Parameter Explanation:

  • <number>: An integer value specifying the number of repetitions. Typically, it ranges from 1 to 40 (depending on account type and server load).
  • Prompt Description: A regular MidJourney prompt used to describe the desired image.

Examples of Usage

  1. Generate the Same Prompt 5 Times 
    /a futuristic cityscape at sunset, ultra-realistic, 8k --repeat 5
    • MidJourney will generate this prompt 5 times, creating a set of images with slight variations.
  2. Repeat a Specific Character Style 
    /a steampunk robot with glowing eyes, cinematic lighting, detailed design --repeat 3
    • This will produce three image sets of a steampunk-style robot, each with potential random adjustments.
  3. Explore Landscape Details 
    /a peaceful mountain scene, golden hour lighting, wide-angle view --repeat 10
    • Ten sets of mountain scene images will be generated, providing multiple options to choose from.

Key Points to Note

  1. Repetition Limitations
    • The number of repeats allowed depends on your account type (Free, Standard, or Pro).
    • Frequent usage may be affected by server load and may slow down processing time.
  2. Usage Cost
    • Each repeat consumes an equivalent amount of GPU time, so plan accordingly.
  3. Randomness in Results
    • While the prompt is repeated, subtle differences in details may appear due to MidJourney’s inherent randomness.
  4. Combination with Other Parameters
    • --repeat can be used alongside other parameters like --ar, --v, and --q.
    • For example: 
      /a neon cyberpunk street, rainy night, cinematic lighting --ar 16:9 --repeat 5

Scenarios for Using --repeat

  1. Image Selection
    • Generate multiple outputs to choose the best version for your needs.
  2. Testing Prompt Effectiveness
    • See how the same prompt performs across multiple runs and identify areas for refinement.
  3. Creative Exploration
    • Observe how slight variations can lead to unexpected yet creative outputs.
  4. Batch Production
    • Quickly produce several variations of an image to meet project requirements.

Summary

Example Full Prompt:

/a fantasy castle on a floating island, clouds and sunlight, highly detailed, ultra-realistic, --ar 16:9 --repeat 3

The --repeat parameter is one of the most efficient tools in MidJourney for batch generation and creative exploration. By specifying the number of repetitions, users can save time, test randomness, and gain diverse image outputs. Combining --repeat with other parameters allows for even greater control over the results.
