Image Upscaling · Artifact Avoidance challenges
Every image upscaling challenge testing Artifact Avoidance, scored with TrueSkill as the votes come in.
Weave Warfare
This challenge is highly revealing for an arena as it directly exposes whether models can maintain complex woven textures without introducing unnatural pattern repetition or losing the authentic fabric feel.
Tokaji Text Trials
This challenge is particularly useful because it tests two of the hardest real-world elements at once — precise text reproduction and realistic handling of glass, reflections, and moisture — which are common failure points in product photography upscaling.
