Lowest Span Confidence: A Zero-Shot Metric for Efficient and Black-Box HallucinationDetection in LLMs
Lowest Span Confidence: A Zero-Shot Metric for Efficient and Black-Box HallucinationDetection in LLMs

Yitong Qiao, Licheng Pan, Yu Mi

Preprint 2026

we propose a novel efficient zero-shot metric called Lowest Span Confidence (LSC) for hallucinationdetection under minimal resource assumptions, only requiring a single forward with output probabilities.
