WorldFact-Bench: Beyond Image-Internal Plausibility to Image-World Consistency

Advances in image generation have made visual authenticity increasingly difficult to assess. Although image forensics now examines both generation artifacts and higher-level visual inconsistencies, a plausible image can still contradict real-world facts or rules. We introduce WorldFact-Bench to evaluate image-world con...

Learning Continuous Source Responses For Generalizable AI-Generated Image Detection

Advances in image generation have made synthetic images increasingly difficult to distinguish from real photographs, raising concerns about the trustworthiness of visual media. Existing AI-generated image detectors often perform well on in-domain data, but their robustness and cross-generator generalization remain limi...

Veritas++: Value-aware On-Policy Distillation for Perception-Enhanced AIGI Detection

This work presents Veritas++, a perception-enhanced reasoning framework that establishes reliable perception as the foundation of authenticity reasoning, and introduces Value-aware On-Policy Distillation (VaOPD), an adaptive distillation mechanism that prioritizes high-value distillation signals over uniform supervisio...
