Harbor Adapters - Omni-MATH (Terminus-2): leaderboard
Omni-MATH, olympiad-level mathematics problems, here 200 of its 4,428: accuracy in percent, judged against the reference answer by GPT-5-mini, a model that is also on this board, higher is better. Each model runs in Terminus-2, the Harbor framework's bash-only terminal agent with no native web or image tools, at its provider's default settings, so results can differ from the same model in its vendor's own agent; the score is the mean of three trials (Harbor Adapters large-scale evaluation; Shi, Lin et al., 2026).
Metric: Accuracy (%; 200 problems, GPT-5-mini judge, mean of 3 trials). Source: arxiv.org. Saturation forecast: Around February 2027. 8 models tracked.
