Stable Diffusion 3 Versus SDXL

The Stable Diffusion 3 generator is about to launch, and it promises to deliver superb quality AI image creation that surpasses other top-of-class models like SDXL. 


While we're currently reliant on early previews, Stable Diffusion 3 appears to have a similar depth of quality and prompt understanding as SDXL but with more refined detailing to match exact text inputs


Stability AI only recently announced a sneak peek into the new model, with limited demos, so much is still subject to speculation. However, introducing open weights, which means the neural network behind the model is open access, could mean that comparisons between Stable Diffusion 3 and DALL-E 3 become a little one-sided in terms of the scope to build on the initial model.


How Does Stable Diffusion 3 Work?


Unlike many well-known AI art creation generators, Stable Diffusion 3 (SD3) isn't one standalone model. Instead, it is a series of models in varying sizes, from 800 million to eight billion parameters. This could mean a few things for regular graphic artwork creators:


  • The scale of the parameters in some SD3 models means that it will take longer to produce unique and on-spec graphics than other platforms.
  • Users wanting a quick turnaround on their artwork creation may be able to opt for an SD3 model version with fewer parameters to speed up the process.
  • Lower parameter models within SD3 will produce simpler and less photorealistic images. Still, the costlier models with longer processing times will be able to create graphics with a level of precision detail we're yet to see.

Stable Diffusion 3 is the latest version and will differ from older iterations in a switch to diffusion transformer architecture. This deviation from the diffusion models used in previous versions allows it to combine large language models simultaneously–improving the capacity of the model to overcome previous limitations.


Rather than being ideal for either great layouts and contextual sizing or best for hyper detail over a small area, SD3 hopes to specialise in both, creating complex and intricate scenes with an equally relevant layout and level of fine detailing. Another interesting snippet of information is that Stable Diffusion 3 uses flow matching, a faster way to train an AI model and transition that learning into images. This should keep the costs of the innovative AI platform under control.


Is Stable Diffusion 3 Better Than Every Other Text-to-Image Generator?


We’re often cautious about stating that one model or platform is superior to every other since a lot depends on the style, tone, and texture of the images you'd like to create–and there isn't any right or wrong answer. 

Although the newest model from Stable Diffusion contains numerous upgrades and dynamic uses of existing technologies, it won’t necessarily be the only AI model we’d suggest, and you’ll likely have your own preferences.

One test looked at Stable Diffusion 3 and Midjourney 6. The latter was only released in December 2023 and introduced as the default model on Midjourney last month.

It found that Midjourney 6 had an edge with some artwork creation projects, interpreting the major elements of a text prompt for a specific film genre very well, performing better than Stable Diffusion 3 in rendering text–if not quite perfect. Midjourney’s latest model also scored the highest marks in other detailed renders, creating the best example of a period interior design scene.

That said, we're still in the early days and will need more opportunities to experiment with SD3's functionality to evaluate its full capacity and how the platform evolves when it is released at scale.


Does Stable Diffusion 3 Solve Issues with AI Model Text Rendering?

Creating graphics with legible, clear text and lettering has long been a challenge, and Stability AI included an image produced through the platform as part of its official announcement. This gives us a pretty good idea of how well the platform will produce text. While the words were readable and showed considerable improvement over previous Stable Diffusion models, they still displayed a few spacing errors.

We also saw an SD3 render of a photorealistic bus driving down a city street with the text 'DREAM ON' on its destination sign. It looked good, but there were some inconsistencies in how the shadows in parts of the graphic looked compared to other background features.


Stable Diffusion 3 is currently in an early preview stage, so once researchers have completed testing, we'll know more!
