LiveCodeBench-Plus: leaderboard

LiveCodeBench-Plus (UC Berkeley and Tsinghua IIIS, BenchEvolver paper, 2026) is a 91-problem stdin/stdout competitive-programming set: 64 harder, human-vetted variants evolved from saturated LiveCodeBench-v6 medium and hard problems plus 27 difficult original LiveCodeBench-v6 problems. Pass@1 in percent averaged over four attempts, higher is better; GPT models ran at medium reasoning effort, Gemini models with adaptive reasoning and DeepSeek-V4-Pro in high thinking mode. Items were selected using the failure rates of the models the paper scores, so its ranking is not independent of item selection.

Metric: Pass@1 (%; mean of 4 attempts). Source: arxiv.org. Saturation forecast: Around February 2027. 8 models tracked.
