Researchers have introduced Omni-Fake, a new benchmark dataset designed to improve the detection of multimodal deepfakes on social media. The dataset includes over 1 million samples across image, audio, video, and audio-video talking head modalities, along with an out-of-distribution benchmark to test generalization. Omni-Fake also supports a protocol for joint detection, localization, and explanation of deepfakes, and introduces a reinforcement-learning-based detector called Omni-Fake-R1 that integrates cross-modal cues for more accurate and explainable results.
