Introducing Stable Diffusion XL v1.0: The Upgraded Version

Stable Diffusion XL v1.0 and Stable Diffusion v1.5 are two versions of the popular Stable Diffusion model that have garnered attention in the AI community. In this article, we will compare the advancements and differences between these two versions and analyze their performance.

Introducing Stable Diffusion XL v1.0: The Upgraded Version

Stable Diffusion XL v1.0 is the latest release that has generated excitement among AI enthusiasts. It offers significant improvements over its predecessor, Stable Diffusion v1.5. The technical tweaks and enhancements in this version have resulted in better performance and output quality.

New Model Architecture, SDXL uses a 2 step refinement pipeline:

  1. Enhanced Training Techniques: The model benefits from improved training methods, resulting in better convergence and more accurate output.
  2. Fine-tuning and Optimization: Stability AI has spent over 1 million A100 hours refining Stable Diffusion XL v1.0, ensuring a solid foundation for future improvements and community-driven development.
  3. Larger Dimensions: SDXL was trained on 1024 x 1024 images, double that of the previous models
SD 1.5 Base model was trained on ~90 million images
SDXL Base model was trained on 6.6 billion images

AI Model Stacks: How Stable Diffusion XL v1.0 Outperforms MidJourney

When comparing Stable Diffusion XL v1.0 with MidJourney, closed source text-to-image model, Stable Diffusion XL v1.0 emerges as the superior option. It offers significant advantages over MidJourney in terms of image quality, stability, and performance.

Another point to note, Stable Diffusion is just the beginning, the open source aspect of the model will allow for a flurry of community support and contributions in the following weeks. We should see a lot of exciting models popping up on Civitai.
