[P]Midjourney is a powerful tool for generating amazing images from text prompts. But did you know that you can fine-tune your results even further by using parameters? These parameters allow you to control various aspects of the image generation process, such as aspect ratio, style, and diversity. In this guide, we'll explore the essential Midjourney parameters you need to know to create the perfect images.

Understanding Midjourney Parameters
When you submit a text prompt to Midjourney, the tool uses default settings to control various aspects of the image generation. Parameters are like extra instructions you add to your prompt to override these default settings. They always start with two dashes (--) followed by the parameter name and its value. For example: --aspect 3:4 tells Midjourney to create an image with a 3:4 aspect ratio.
Basic Syntax
The basic format for using parameters is: --parameter_name value. Remember to place parameters at the end of your prompt and separate multiple parameters with a space.
Key Parameters to Master
Version: Choosing Your Midjourney Model
[P]The version parameter controls which Midjourney model is used to generate your images. Different models have different styles and prompt understanding capabilities. To use a specific model, use the --version or --v parameter followed by the model number. For example, --v 5. For models like test and testp use --test or --testp. Here are some current values you can use:</P]
--v 3: Uses the V3 model.
--v 4: Uses the V4 model.
--v 5: Uses the V5 model.
--v 5.1: Uses the V5.1 model.
--v 6: Uses the V6 model.
--test: Uses the test model.
--testp: Uses the testp model.
--ni: Uses the Niji model.
Aspect Ratio: Controlling Image Dimensions
Aspect ratio defines the relationship between the width and height of your image. The default is 1:1 (square). To change it, use --aspect or --ar followed by the desired ratio (e.g., --ar 16:9 for a widescreen image). Use whole numbers and be aware of the limits on how tall or wide your images can be.
Chaos: Adding Variety to Your Results
The chaos parameter affects the diversity of the images generated in your grid. The default value is 0, and it ranges up to 100, with higher values resulting in more diverse images. Use --chaos or --c followed by a value (e.g., --chaos 50).
Stylize: Influencing the Artistic Style
Each Midjourney model has a default visual aesthetic. The stylize parameter controls the strength of this aesthetic. The default value is 100, and the range is 0 to 1000. Use --stylize or --s followed by a value. A higher value gives you more stylized results but may reduce prompt adherence.
Style Reference: Copying Visual Styles
Style reference (--style_reference or --sref) is a powerful feature that allows you to apply the aesthetic elements of one or more images to your results. You can use image URLs or sref codes. Style weight (--style_weight or --sw) controls the influence of the style reference, with a default value of 100 and a range of 0 to 1000.
Style: Adjusting the Aesthetic Mode
The style parameter allows you to minimize Midjourney's default aesthetic influence. Using --style raw can be helpful for achieving more photorealistic images.
Quality: Balancing Detail and Speed
The quality parameter controls the amount of time and power Midjourney spends generating your images. The default value is 1. Lower values result in faster generation but less detail, while higher values provide more detail but take longer. Use --quality or --q followed by a value.

Speed and Efficiency Parameters
Turbo, Fast, and Relax: Choosing Your Speed Mode
Midjourney offers different speed modes for image generation. Turbo and fast use your fast GPU hours, while relax mode does not. You can set your default speed mode in your settings, but you can override it with the --turbo, --fast, or --relax parameter.
Repeat: Running Prompts Multiple Times
The repeat parameter (--repeat or --r) allows you to run the same prompt multiple times. It can only be used with fast or turbo mode. For example, --repeat 5 will run the prompt five times.
Advanced Parameters for Fine-Tuning
Video: Creating Time-Lapse Videos
The video parameter (--video) creates a short time-lapse of your initial image grid being generated. After generating images using the --video parameter on Discord, react to it with the envelope emoji, and the Midjourney bot will send you a direct message containing a link to the video.
Stop: Ending Image Generation Early
The stop parameter (--stop) lets you end image generation early, taking values between 10 and 100. This can be useful for creating softer, more abstract results. For example, --stop 50 stops the process at 50% completion.
Image Weight: Influencing with Images
Image weight (--iw) can only be used with image prompts. It controls how much influence the images have on the results. The default value is 1, and in Midjourney V6, it takes decimal values between 0 and 3.
Character Reference: Matching Characters
Character reference (--cref) is similar to style reference but focuses on matching a character from a reference image. Character weight (--cw) controls how closely Midjourney adheres to the clothing and hairstyle of the reference character.
Personalize: Creating Your Own Custom Model
Personalization (--p) allows you to create your own custom Midjourney model based on your preferred visual aesthetics. You first need to teach Midjourney about your style. When enabled, your personalized model will override the default Midjourney aesthetic.
No: Excluding Elements from Your Image
The no parameter (--no) tells Midjourney what you don't want in your image. Add --no followed by the elements you want to exclude, separated by commas (e.g., --no trees, buildings).
Tile: Creating Repeating Patterns
The tile parameter (--tile) is used for creating repeating patterns. It doesn't require any values, and the resulting images can be tiled to create seamless patterns.
Seed: Controlling Randomness
Each Midjourney job starts with a seed number, which is a random number that determines the initial noise pattern. If you want to use a particular seed number, use the --seed parameter (e.g., --seed 1234). This can be useful for testing how parameter values affect results.
Weird: Embracing the Unexpected
The weird parameter (--weird or --w) introduces strange and unexpected results. The default value is 0, and it takes values up to 3000. Experiment with different values to see what works best for your prompts.
