SciFigPlag-Bench - Pairwise Detection: leaderboard

SciFigPlag-Bench (2026) pairwise detection: given a source and a suspicious scientific figure, decide whether the suspicious one reuses the source, against visually similar negatives. Accuracy in percent, higher is better.

Metric: Accuracy (%; yes or no: does the suspicious figure reuse content of the source figure; SciFigPlag-Bench pairs of source and suspicious scientific figures (2,582 plagiarized pairs from documented real cases and taxonomy-guided synthesis, 2,541 visually similar negatives); the same task-specific prompts for every model, temperature 0). Source: arxiv.org. Saturation forecast: Estimated already saturated. 16 models tracked.
