CoRE (Code Reasoning) - CoT: leaderboard
Metric: Reasoning Consistency Score (RCS, %) with two-shot chain-of-thought prompting: 60 HumanEval and LiveCodeBench problems with 255 expert-verified functionally equivalent implementations and intermediate-state probes; per problem the score is the strict output consistency (every implementation and test predicted correctly, 0 or 1) times the share of intermediate probes answered correctly, averaged over problems; higher is better.
