LiveCodeBench.

Contamination-free coding benchmark collecting new problems from LeetCode, AtCoder, and CodeForces after model knowledge cutoffs. Updated continuously with fresh problems. Primary metric is pass@1 on the full test set.

Best published scores.

54 results indexed across 2 metrics. Shaded row marks current SOTA; ties broken by submission date.

of state of the art.

Each row below marks a model that broke the previous record on pass@1. Intermediate submissions are kept in the leaderboard above; only SOTA-setting entries are re-listed here.

Higher scores win. Each subsequent entry improved upon the previous best.
