A Comprehensive Guide to Midjourney Parameters: Mastering AI Image Generation


September 2nd, 2024 – Updated for v6.1

Midjourney has revolutionized AI-generated art, allowing creators to produce stunning visuals with just a few words. To truly harness the power of this tool, you need to understand its parameters. In this comprehensive guide, we’ll dive deep into Midjourney parameters, providing you with the knowledge to elevate your AI art game.

Understanding Midjourney Parameters

Parameters are options added to a prompt that change how an image generates. They can alter aspect ratios, switch between model versions, change upscalers, and much more. Parameters are always added to the end of a prompt, and you can use multiple parameters in each prompt.

/imagine prompt: A serene lake at sunset --ar 16:9 --q 1 --v 5

In this example, we’re using three parameters: aspect ratio, quality, and version.

Basic Parameters

Let’s explore some of the most commonly used parameters:

1. Aspect Ratio (–ar or –aspect)

Changes the aspect ratio of the generated image.

/imagine prompt: Cyberpunk cityscape --ar 2:1

2. Chaos (–chaos)

Influences how varied the results will be. Higher values produce more unusual and unexpected generations.

/imagine prompt: Abstract emotion --chaos 50

3. Quality (–q or –quality)

Determines rendering quality and time. Values can be .25, .5, 1, or 2 with 1 being the highest quality. A new ‘quality’ parameter (–q) has been introduced in 6.1. Using –q 2 can potentially increase texture at the cost of reduced image coherence and longer generation time.

/imagine prompt: Detailed landscape --q 1

4. Seed (–seed)

Sets a specific seed for reproducibility. Seeds are integers between 0 and 4294967295.

/imagine prompt: Futuristic space station --seed 1234

5. Stop (–stop)

Finishes a job partway through the process, resulting in less detailed images. Values range from 10 to 100.

/imagine prompt: Misty forest --stop 80

Advanced Parameters

6. Style (–style)

Switches between different model versions or applies specific styles.

/imagine prompt: Anime character --style cute --niji 5

7. Stylize (–s or –stylize)

Influences how strongly Midjourney’s default aesthetic style is applied. Values range from 0 to 1000, with 100 as default.

/imagine prompt: Portrait of a wise old man --s 750

8. Tile (–tile)

Generates images that can be used as repeating tiles for seamless patterns.

/imagine prompt: Art deco pattern --tile

9. Weird (–weird or –w)

Explores unusual aesthetics. Values range from 0 to 3000.

/imagine prompt: Surreal dreamscape --w 1000

10. Version (–v or –version)

Specifies which version of the Midjourney algorithm to use.

/imagine prompt: Futuristic cityscape --v 5.2

11. Uplight (–uplight)

Uses a lighter upscaling algorithm, resulting in faster processing but potentially less detail.

/imagine prompt: Futuristic cityscape --v 5.2

Uses a lighter upscaling algorithm, resulting in faster processing but potentially less detail.

12. No (–no)

Specifies elements to exclude from the generated image.

/imagine prompt: Fantasy dragon --no fire

13. Video (–video)

Generates a video showing the image generation process from start to finish. Note: This may increase processing time.

Model Version Compatibility

Different Midjourney model versions support various parameters. Here’s a quick overview of compatibility for some key parameters:

Tips for Effective Parameter Use

Experiment with different parameter combinations to find what works best for your style.

Remember that some parameters affect initial generation, while others impact variations and remixes.

Use the --seed parameter to recreate or iterate on specific results.

Adjust the --stylize parameter to find the right balance between Midjourney’s style and your prompt.

Utilize the --quality parameter to balance between speed and detail in your generations.
