All these Sref codes are pulled straight from our carefully curated repository. Click here and explore the rest to find many more options that can further refine your Midjourney prompts.

A Quick Look at Midjourney

Midjourney is an AI tool that generates images from text prompts. By using advanced machine learning, it turns your written ideas into unique and detailed artwork. If you’re interested in creating AI-based interiors, concept art for stories, or just experimenting with design, Midjourney can help you produce amazing visuals with minimal effort. If you need help learning how to write effective prompts, you have come to the right place!

What Are Sref Codes And How to Use?

Sref codes (= style reference codes) are shortcuts for applying a specific look or style to your Midjourney images. Instead of typing a long description of the style each time, you can just include a short code (for example, --sref 1234) to instantly get that style.

When you use the same code in multiple prompts, you keep a consistent look across all your images. This is very helpful if you’re creating a series of related artworks or need a uniform aesthetic for a project.

But how to use Sref codes? Simply add --sref plus the code number to the end of your prompt. Example: alien city at night --sref 1234
