RFEval - Mathematical Reasoning: leaderboard

Metric: Contrast-conditional reasoning faithfulness (%): after a counterfactual flawed reasoning segment is injected into the model's own thinking, the share of pairs in which the continued reasoning stays consistent with that stance and the stance causally carries into the final answer, computed only over the model's own contrast pairs (injection opposes its baseline stance; well-formed outputs); stances extracted by an o3 judge; greedy decoding; Mathematical Reasoning task (1,029 items from MMLU and GSM8K); a property of reasoning traces rather than task accuracy; higher is better.
