VLM-RobustBench (MMBench): leaderboard

Metric: Mean relative corruption error (percent of visual gain lost): for each of the 133 corrupted settings: 42 severity-based corruptions in nine categories (noise, blur, weather, digital, geometric and others) at low, mid and high severity, plus 7 binary transforms such as vertical flip and colour inversion; direct-answer prompting, the accuracy drop from clean images divided by the visual gain (clean accuracy minus the no-image accuracy), averaged over all 133 settings, on a stratified 20 percent sample (869 questions) of the MMBench English dev split; 100 means the corruption removes all visual benefit, values can be negative or exceed 100; lower is better. Source: arxiv.org. Saturation forecast: Around January 2027. 9 models tracked.
