UOJ-Bench - Generation: leaderboard

The code generation task of UOJ-Bench (2026): solve 672 competitive programming problems from IOI-level contests and UOJ original rounds, passing all tests including the extra tests the community added through hacks. UOJ-Bench (2026) draws on real Universal Online Judge submissions and community hacks and judges every answer on the judge itself; Pass@1 in percent, higher is better.

Metric: Pass@1 (%) over all 672 generation problems (UOJ originals and the problems behind the hacking and repair sets, easy to ultrahard): a solution passes when it clears every primary test and every community-added extra test, single-turn zero-shot Pass@1 judged by the Universal Online Judge through its internal API (problem statements translated from Chinese to English; maximum response length at least 64k tokens); higher is better.
