Stable Diffusion XL

Stable Diffusion XL (SDXL) is Stability AI's flagship text-to-image model, delivering high-resolution (1024x1024) photorealism and legible text generation with significantly simpler prompts.

SDXL is Stability AI's most advanced open-source image model, engineered for production-grade creative work. It utilizes a novel two-stage 'ensemble of experts' architecture: a 3.5 billion parameter base model generates the initial latent image, and an optional refiner model adds high-frequency detail. This design allows SDXL to produce images up to 1024x1024 resolution, a major jump from previous versions. Key performance gains include superior photorealism, enhanced image composition, and the ability to render coherent, legible text within images, all while requiring shorter, less complex text prompts for excellent results.
