Chapter 1: The Emergence of SDXL

The public beta of SDXL has launched, bringing it to a level comparable with Midjourney, as it can now generate both images and text without the need for extensive prompts.

Since Midjourney's v5 release, there have been notable enhancements in the realism of character portrayals, including intricate details like fingers. Improvements have also been made in understanding prompts, aesthetic variety, and language processing. Conversely, Stable Diffusion, while being free and open-source, still relies on users crafting lengthy prompts and often necessitates multiple attempts to achieve high-quality images.

Previously, Stability AI announced the development of Stable Diffusion XL, which is currently available for public testing on the Clipdrop platform. Emad Mostaque, the founder and CEO of Stability AI, mentioned that the model is still undergoing training and will be open-sourced once the parameters are more stable. SDXL excels in areas like image intricacies—such as "handshake" details—and offers nearly complete control over the output. However, it is worth noting that "Stable Diffusion XL" is not the final name and shouldn't be classified as v3, since its architecture closely mirrors that of the SD-v2 series. Officially released example images from SDXL showcase an impressive level of quality.

Nevertheless, some users feel that the quest for improved quality has led SDXL to impose excessive rules, thereby reducing customization options that cater to broader preferences. As it stands, v1.5 of Stable Diffusion continues to be the favored base model in the community. Users are hopeful that the new iteration of SD will retain compatibility with the embeddings, hypernetworks, and Lora models from SD 2.1, as starting anew for retraining would be a daunting task.

Some have also pointed out that SDXL's performance appears similar to models available on the Civit platform, with the new model's effectiveness being perceived as average rather than groundbreaking.

Chapter 2: Insights into Stable Diffusion XL

Specific information about the architecture of Stable Diffusion XL has yet to be disclosed by official sources. What is known is that it shares similarities with the v2 models but operates on a larger scale with increased parameters. While SD-v2.1 has 900 million parameters, SDXL boasts approximately 2.3 billion parameters. Emad has hinted at the potential release of a smaller distilled version alongside the official launch.

The enhancements in SDXL compared to its predecessors are notable:

• High-quality images can be produced with shorter descriptive prompts.
• The generated images align more closely with the prompts provided.
• Human body structures in the outputs are rendered more realistically.
• In comparison to v2.1 and v1.5 (to a lesser degree), SDXL-generated images are deemed more aesthetically pleasing according to Fosse aesthetics.
• Negative prompts are optional.
• The generated portraits exhibit greater lifelikeness.
• Text within the images is clearer and more legible.

It's important to note that SDXL may not be fully compatible with plugins from earlier versions. While earlier iterations of Stable Diffusion struggled with generating readable text, SDXL has made significant strides in this area, although it may not always achieve perfect accuracy.
