📷 Custom Prompt Parameters in Mid-Journey

In this paragraph, Jen introduces the concept of custom prompt parameters in the mid-journey platform. She explains that these parameters, which are dash-dash commands placed at the end of a prompt, provide specific instructions to mid-journey on how the image should look. Jen highlights the benefits of using custom prompts to avoid repetitive typing and to keep one's 'image recipes' secret. She demonstrates how to set a preferred suffix using the 'slash prefer suffix' command, which automatically adds a specific command to every prompt created. This can include aspects like video options or aspect ratios. The paragraph also touches on the ability to create multiple sets of preferred options using 'slash prefer option set', allowing for different image styles and keeping some parameters secret from others.


🔍 Managing and Using Custom Prompt Options

This paragraph delves deeper into managing custom prompt options in mid-journey. Jen explains how to list all preferred options using 'slash prefer option list', which provides a comprehensive view of the commands associated with each set. She also discusses the flexibility of editing option sets by reusing the same name and entering different values. The paragraph provides an example of creating a set called 'photo' with parameters aimed at generating realistic images. Additionally, Jen mentions the limitation of using certain parameters together and the process of updating them. The paragraph concludes with a mention of the ethos of mid-journey, which is sharing, but also acknowledges the desire to keep some creative processes private. Jen invites viewers to share their favorite custom parameters in the comments and encourages engagement with the channel.



💡Custom Prompt Parameters

Custom Prompt Parameters refer to the specific commands or instructions that users can set within the 'Slash prefer' feature in Midjourney, a generative AI tool. These parameters are used to control the style, quality, and other aspects of the images generated by the AI. In the video, the creator demonstrates how to use these parameters to save time and maintain consistency in image creation, as well as to keep certain creative processes secret from others.


Midjourney is the name of the AI tool being discussed in the video. It is a platform that uses generative AI to create images based on textual prompts provided by the user. The video focuses on how to enhance the user experience with Midjourney by utilizing custom prompt parameters to achieve desired outcomes more efficiently.

💡Slash Prefer

Slash Prefer is a command within the Midjourney tool that allows users to set preferences for their image generation process. It is used to establish custom parameters that can be applied to every prompt, ensuring that the AI generates images according to the user's specific requirements. The video explains how to use Slash Prefer to set a preferred suffix and create option sets for different types of images.


In the context of the video, a suffix is a set of commands that are automatically added to every prompt the user creates in Midjourney. By setting a preferred suffix using the Slash Prefer command, users can ensure that certain parameters are consistently applied to all their image generation requests, streamlining the process and reducing the chance of forgetting important settings.

💡Option Set

An Option Set in Midjourney is a collection of parameters that users can create and name for different types of images they wish to generate. These sets can be customized to include various commands that will produce specific styles or qualities in the images. The video demonstrates how to create, apply, and edit option sets to achieve different visual outcomes with the AI tool.

💡Aspect Ratio

Aspect Ratio is a term used to describe the proportional relationship between the width and height of an image or canvas. In the video, the creator sets a preferred aspect ratio of 9 by 16 using the custom prompt parameters to ensure that the generated images have this specific shape, rather than the default square format.


In the context of Midjourney, Chaos refers to a parameter that controls the level of randomness or imaginativeness in the generated images. A higher Chaos value allows the AI to create more varied and unpredictable results, while a lower value results in more consistent and controlled outcomes. The video mentions setting Chaos at 5 as part of a custom prompt parameter.


Stylized in the video refers to a parameter that influences the artistic style of the generated images. By adjusting the stylized value, users can control how much the AI emphasizes certain artistic qualities, such as brush strokes or color gradients. The creator mentions changing the stylized value to 1250 in an option set to achieve a more realistic photo-like image.

💡Process Video

A Process Video, as mentioned in the script, is a type of video content that shows the step-by-step creation of something, often used for educational purposes. In the context of Midjourney, a process video might demonstrate how to use the tool's features, such as custom prompt parameters, to generate images step by step.

💡Descriptive Words

Descriptive Words are used in the video to refer to additional text that can be included with custom prompt parameters to provide more context or specificity to the AI. These words help the AI understand the user's intent and can influence the style or subject matter of the generated images. The creator uses 'Chia' as an example of a descriptive word, which is short for 'quiero squirrel,' an artistic lighting style.

💡Artists Initials

In the video, the creator mentions using artists' initials as part of the custom prompt parameters. This is a personal touch that adds a layer of secrecy to the creative process, as it references specific artists in a way that is known only to the creator. It allows the user to generate images inspired by particular artistic styles without revealing the exact reference to others.
