Discover legacy tools and features that shaped Midjourney's evolution.

If you’re curious about the older versions of Midjourney and the features they offer, you’ve come to the right place. As we keep moving forward with the latest updates, we also want to acknowledge and explore the tools and options from previous models that helped shape Midjourney to what it is today.

Legacy Versions

Version 5.2

Version 5.2 was released in June 2023. It was the default model from June 22, 2023 to February 14, 2024. Version 5.2 produces more detailed, sharper results with better colors, contrast, and compositions. It also has a slightly better understanding of prompts than earlier models and is more responsive to the full range of the --stylize parameter.

Version 5.1

Version 5.1 was released on May 4th, 2023. It was the default model from May 3, 2023 to June 22, 2023. Version 5.1 has a stronger default aesthetic than earlier versions, making it easier to use with simple text prompts. It also has high coherency, excels at accurately interpreting natural language prompts, produces fewer unwanted artifacts and borders, has increased image sharpness, and supports advanced features like repeating patterns with --tile.

Version 5

Version 5 was released in March 2023. It was the default model from March 30, 2023 to May 3, 2023. Version 5 produces more photographic generations than the V5.1 model, and produces images that closely match the prompt but may require longer prompts to achieve your desired aesthetic.

Niji 5

The Niji 5 model was released in April 2023. It can be fine-tuned with specific --style parameters including:
• --style cute creates charming and adorable characters, props, and settings.
• --style expressive has a more sophisticated illustrated feeling.
• --style original uses the original Niji Model Version 5, which was the default before May 26th, 2023.
• --style scenic makes beautiful backgrounds and cinematic character moments in the context of their fantastical surroundings.

Default Parameter Values

Upscalers: Version 5 features the Upscale (2x) and Upscale (4x) tools, which are not compatible with Pan or Tile. 

• Version 4

  Version 4 was released in November 2022. It was the default model from December 20, 2022 to March 30, 2023. Version 4 is an entirely new codebase and brand-new AI architecture (compared to previous versions) designed by Midjourney and trained on the new Midjourney AI supercluster. Version 4 has more knowledge of creatures, places, objects, and more than previous versions. It's much better at getting small details right and can handle complex prompts with multiple characters or objects. Version 4 supports advanced functionality like image prompting and multi-prompts, and has very high coherency and excels with Image Prompts.
  
  Version 4 has three slightly different "flavors" with slight tweaks to the stylistic tuning of the model. Experiment with these versions by adding --style 4a, --style 4b, or --style 4c to the end of a V4 prompt. 4c is the default and support aspect ratios up to 1:2 or 2:1. 4a and 4b only support 1:1, 2:3, and 3:2 aspect ratios.

  Niji 4

  Midjourney's first Niji model, Niji 4, was released on December 20, 2022. 
  
  Default Parameter Values
  

  	Aspect Ratio	Chaos	Quality	Seed	Stop	Style	Stylize
  Default Value	1:1	0	1	random	100	4c	100
  Range	1:2–2:1	0-100	0.25, 0.5, 1	0-4294967295	10-100	4a, 4b, 4c	0-1000

  
  Upscalers: Earlier Midjourney model versions start by generating a grid of low-resolution image options for each Job. You can use a Midjourney upscaler on any of these images to increase the size and add additional details. The table below shows image sizes for 1:1 ratio images. For more information view our Upscalers article.
  
  

  Model Version	Starting Grid	Default Upscale	Detail Upscale	Light Upscale	Beta Upscale
  Version 4	512 x 512px	1024 x 1024px	1536 x 1536px	1536 x 1536px	2048 x 2048px
  Niji 4	512 x 512px	1024 x 1024px	1024 x 1024px	1024 x 1024px	2048 x 2048px

• The --test and --testp models were introduced in August 2022 as part of Midjourney's effort to gather community feedback and improve upon new features. These test models allow users to explore upcoming capabilities, and they can be used alongside the --creative parameter for more varied compositions. When using these models, keep in mind that they support --stylize values ranging from 1250 to 5000, offering strong artistic influence.

  There are some limitations with the test models. They do not support multi-prompts or image-prompts and have a maximum aspect ratio of 3:2 or 2:3. When the aspect ratio is 1:1, they generate two initial grid images, but with other aspect ratios, they produce only one initial grid image. Additionally, in crafting prompts, note that words at the beginning of your prompt may hold more weight than those at the end. These unique characteristics make the test models an exciting option for experimental image creation.

  Upscalers: Initial grid images are 512 x 512px and the only option to upscale is Beta Upscale, which creates a 2048 x 2048px image when using 1:1 aspect ratio. For more information view our Upscalers article.

• Version 1

  Version 1 was the default model from February 2022 to April 2022. Version 1 is very abstract and painterly with low coherency.

  Version 2

  Version 2 was the default model from April 2022 to July 2022. Version 2 is creative, colorful, and painterly with low coherency.

  Version 3

  Version 3 was the default model from July 2022 to November 2022. Version 3 generates highly creative compositions with moderate coherency.
  
  V3 Legacy Parameter: --sameseed Seed values create a single large random noise field applied across all images in the initial grid. When --sameseed is specified, all images in the initial grid use the same starting noise and will produce very similar generated images.

  High Definition

  --hd is an early alternative model that generates busy, detailed, and abstract images with low coherency.
  
  Upscalers: Earlier Midjourney model versions start by generating a grid of low-resolution image options for each Job. You can use a Midjourney upscaler on any of these images to increase the size and add additional details. The table below shows image sizes for 1:1 ratio images.

Legacy Upscalers

In previous Midjourney model versions, images generated at smaller sizes. You can still enlarge these images using a legacy upscaler. These tools not only increase the size but also add more details. There are various legacy upscalers you can choose from for images made with earlier models. Keep in mind, using a legacy upscaler will use GPU minutes.

Version 5

Midjourney model versions 5.x produce 1024 x 1024 pixel images. You can then use the Upscale (2x) or Upscale (4x) tools to increase the size of your image to 2048 x 2048 pixels or 4096 x 4096 pixels respectively. V5 upscale tools are not compatible with the pan tool or the tile parameter.

Versions 4 & Earlier

Each of these upscalers changes your image in different ways. All sizes are in pixels and for square aspect ratios.

* = the default upscaler for each Midjourney Version Model.
** Max Upscale is an older resource-intensive upscaler and is only available when users are in Fast Mode.

When using legacy versions, the --uplight or --upbeta parameters in your prompt will turn the U# buttons in Discord into Light Upscale or Beta Upscale shortcut buttons.

Style Tuner

The Style Tuner is a Discord feature in Midjourney version 5.2, and it set the stage for Personalization. With this tool, you can use the /tune command along with a prompt to generate a variety of sample images. Each image showcases a different visual style based on your provided prompt. Generating these sample images uses your subscription Fast time, and it can't be used in Relax Mode.

Once you pick the images you like the most, the Style Tuner gives you a special --style code. You can use this parameter to tailor the look of your future images, giving them a distinct style. These style code parameters can be combined and shared with other Midjourney subscribers. 

Using the /list_tuners command will generate a list of all of the Style Tuners you have created.

Remaster

Remaster is a Discord button for upscaled images generated using legacy versions of Midjourney. It automatically remixes your prompt into version v5.2. Remaster any previously upscaled job by clicking the 🆕 Remaster button beneath the upscaled image.
