Benchmark Methodology
Copyleaks was evaluated on a curated dataset of 1 images across 1 AI image generators and 1 watermark types, including models like Midjourney, Stable Diffusion, DALL-E 3, Flux, and others. The dataset also includes real photographs from verified sources to measure false positive rates.
All detectors are tested under identical conditions using the same images. We record each detector's classification (AI or Real) and confidence score, then compute three key metrics: Accuracy (percentage of correct predictions), False Positive Rate (real images incorrectly flagged as AI), and False Negative Rate (AI images missed by the detector).
