RPCBench - Error Group - Underspecified Premise - Evidence Faithfulness: leaderboard
RPCBench tests proactive premise critique in recommendation requests. This series measures evidence faithfulness on the Underspecified Premise subset (1,300 questions), using the same eleven-model, three-judge experiment as the headline paper. Published EFI fractions from the authors' per-model CSV are scaled once to Faithfulness Index (%). Higher is better; domains and nested premise-error groups are related slices of the same experiment.
Metric: Faithfulness Index (%). Source: github.com. Saturation forecast: Not forecast. 11 models tracked.
