Image Upscaling challenges
Every image upscaling challenge in the arena, scored with TrueSkill as the votes come in. Filter by skill to narrow it down.
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.
Freckle Fortress Challenge
This challenge is excellent for an arena because it forces AI models to prove they can enhance ultra-fine organic skin details without destroying freckles or turning skin into an unnatural plastic or overly smooth surface.

Feather Fidelity Challenge
This challenge is excellent for an image arena because it brutally tests whether AI models can preserve and enhance extremely fine, layered organic structures (individual feather barbs, color gradients, and beak texture) without creating unnatural repeating patterns or over-smoothing the details.

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.
