Align, Don't Blend: Orthogonal Supervision Disentanglement As the Key to Generalizable AI-Generated Image Detection

The paper argues that AI‑generated image detection has focused too much on model design and not enough on how supervision is structured. By replacing blended supervision with orthogonal, disentangled supervision—semantic signals for a vision‑language model and artifact signals for a vision expert—the authors show a 9.5% improvement on five in‑the‑wild benchmarks. They also introduce the AIGI‑Now benchmark to evaluate detectors on eight modern generators with separate semantic and pixel‑level tests.

FUSED: Forensic-Semantic Mixture-of-Experts for AI Inpainting Detection and Localization

FUSED is a new framework that jointly detects and localizes AI-generated inpainting by combining low-level forensic cues with high-level semantic features through a sparsely-gated Mixture-of-Experts architecture. It predicts both an image-level manipulation score and a pixel-level mask of the inpainted region. On the OpenSDID cross-generator benchmark, FUSED outperforms existing methods, especially on unseen generators, and transfers effectively to the AutoSplice and CocoGlide benchmarks, doubling localization performance.
