Midjourney V6.1 New Features Explained in Detail: Personalization Codes, Image Quality, and Style Control

The focus of this Midjourney update is very clear: a more usable model, a generation method that better matches individual tastes, and a visible improvement in image quality. This article covers only the new features of Midjourney V6.1, broken down from the perspective of “something you can start using immediately.” After reading, you’ll be able to improve the stability and consistency of Midjourney outputs.

V6.1 New Model: More stable and more controllable with the same prompt

Midjourney V6.1 is a model-level update. The core change is a more stable understanding of prompts, making it easier for details to “grow according to the description.” If you previously often ran into issues in Midjourney like the main subject drifting off, muddy materials, or uncontrolled piling on of details, V6.1 will reduce the need for rework.

Getting started is simple: in Midjourney settings, switch the default model to V6.1, then use the same prompt to compare with older results. It’s recommended to run regression tests first on your commonly used commercial scenarios (product images, half-body portraits, spatial renderings), where the differences are easiest to see.

Personalization Code: Turn “your aesthetics” into reusable parameters

Another practical feature in V6.1 is the “personalization code.” The logic is: you first make preference selections in Midjourney’s personalization flow (for example, rating your preference across multiple groups of images), and the system generates an exclusive code based on that.

When using it, you append this personalization code to the end of your prompt, and Midjourney will lean more toward the compositions, textures, or stylistic tendencies you like. It’s especially suitable for making image series: the same brand key visual, the same character setup, the same spatial style—all can reduce the feeling that “each time it’s like opening a new blind box.”

Image Quality Upgrade: Cleaner details, more confidence when upscaling

Based on interpretations of the update from both the official source and the community, improving image quality is a genuine direction in Midjourney V6.1—especially making it more deliverable in terms of textures, edges, and overall sharpness. For scenarios like e-commerce, posters, and UI concept art that require “usable details,” the usable output rate will be higher.

A practical recommendation: first use V6.1 to generate the composition you want, then do an upscale and a detail check (skin, fabric, metallic reflections, and text edges are the most obvious). If you find it’s “clearer but sharper,” go back to the prompt and add material terms (such as matte, soft light, film grain) to push Midjourney’s texture back toward the direction you want.

Post-update Workflow: Set the model first, then personalization, then style

If you want to make full use of Midjourney’s new features, don’t reverse the order: first confirm that you’re consistently using V6.1, then establish your personalization code, and only then fine-tune style words and lens words. This way, each iteration in Midjourney stays on the same baseline, making results more predictable.

If your team shares prompt templates among multiple people, it’s recommended to write “model version + personalization code placement” into your guidelines. Midjourney’s differences often aren’t in the prompt itself, but are caused by model and personalization toggles being out of sync.
