AI-GenBench: A New Ongoing Benchmark for AI-Generated Image Detection
This addresses the urgent need for robust detection of AI-generated images to ensure media authenticity, primarily for researchers and non-experts like journalists, but it is incremental as it builds on existing detection methods with a new benchmark.
The authors tackled the problem of detecting AI-generated images by introducing Ai-GenBench, a benchmark that uses a temporal evaluation framework to test detection methods' generalization to new generative models, resulting in a comprehensive dataset and standardized protocol for reproducible comparisons.
The rapid advancement of generative AI has revolutionized image creation, enabling high-quality synthesis from text prompts while raising critical challenges for media authenticity. We present Ai-GenBench, a novel benchmark designed to address the urgent need for robust detection of AI-generated images in real-world scenarios. Unlike existing solutions that evaluate models on static datasets, Ai-GenBench introduces a temporal evaluation framework where detection methods are incrementally trained on synthetic images, historically ordered by their generative models, to test their ability to generalize to new generative models, such as the transition from GANs to diffusion models. Our benchmark focuses on high-quality, diverse visual content and overcomes key limitations of current approaches, including arbitrary dataset splits, unfair comparisons, and excessive computational demands. Ai-GenBench provides a comprehensive dataset, a standardized evaluation protocol, and accessible tools for both researchers and non-experts (e.g., journalists, fact-checkers), ensuring reproducibility while maintaining practical training requirements. By establishing clear evaluation rules and controlled augmentation strategies, Ai-GenBench enables meaningful comparison of detection methods and scalable solutions. Code and data are publicly available to ensure reproducibility and to support the development of robust forensic detectors to keep pace with the rise of new synthetic generators.
