ConfBench - Confidence AUROC: leaderboard
ConfBench (Amazon, 2026) degrades 75 verified invoices with 20 controlled augmentation pipelines into 1,346 variants and asks a vision-language model to extract entities and state a confidence for each, here as verbalized top-4 guesses from the OCR text plus the image. Score is the AUROC of the confidences for telling correct from incorrect extractions, on a 0-1 scale where 0.5 is chance; higher is better.
Metric: AUROC of the verbalized confidence for separating correct from incorrect extracted entities (0-1, 0.5 is chance; verbalized top-4 guesses with probabilities in one call, OCR text with Amazon Textract confidences plus the document image, over the entity fields of 1,346 degraded variants of 75 RealKIE-FCC-Verified invoices). Source: arxiv.org. Saturation forecast: Around February 2027. 7 models tracked.
