The paper proposes Artifact-Complementary Expert Fusion (ACEF), a two‑stage framework that enhances AI‑generated image detection by combining two types of reconstruction artifacts—VAE/DDIM and SRGAN—into aligned synthetic negatives. ACEF first builds artifact‑specific experts using LoRA adaptation on a frozen backbone, then fuses their multi‑layer evidence with Layer‑wise Artifact‑Complementary Fusion (LACF) to mitigate conflicts between artifact manifolds. Experiments on 13 benchmarks show that this approach improves generalizability over existing state‑of‑the‑art methods.

The paper introduces RIFT, a forensic framework for detecting AI-generated videos by exploiting a cross‑scale coupling mismatch between macro‑level temporal dynamics and micro‑level pixel residuals. RIFT comprises a macro stream that models expected temporal evolution, a micro stream that probes residual patterns, and a coupling divergence module that quantifies their conditional dependency. Experiments on VidProM and GenVidBench show near‑perfect F1‑scores and robust performance across different encoders.

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.

Forensic Twins introduces a Self‑Supervised Residual Learning (SSRL) framework that trains on real images only, using a frozen forensic residual extractor to generate two disjoint crops per image. The pretext task suppresses semantic content, focusing the model on the stationary fingerprint of the image acquisition pipeline, and achieves 56.61% accuracy in attributing AI‑generator sources, outperforming prior zero‑shot methods. When combined with an offline Gaussian Mixture Model, the approach reaches 97.99% AUC across 27 unseen AI generators, including GANs, diffusion models, and commercial systems.

The paper introduces MoE-JEPA, a dual‑stream deepfake detection model that combines a V‑JEPA backbone with a Residual Mixture‑of‑Experts mechanism and a noise stream branch. It further incorporates a Gated Attention Multiple Instance Learning module to refine spatial semantic understanding. On the SID‑Set benchmark, MoE‑JEPA achieves a new state‑of‑the‑art accuracy of 95.54%, outperforming much larger models.
