RPCBench - Domain - Amazon Sports - Fact Fabrication: leaderboard
RPCBench tests proactive premise critique in recommendation requests. This series measures fact fabrication on the Amazon Sports subset (1,270 questions), using the same eleven-model, three-judge experiment as the headline paper. Published FFR fractions from the authors' per-model CSV are scaled once to Fact Fabrication Rate (%). Lower is better; domains and nested premise-error groups are related slices of the same experiment.
Metric: Fact Fabrication Rate (%). Source: github.com. Saturation forecast: Estimated already saturated. 11 models tracked.
