Harbor Adapters - AIME 2024-2025 (Terminus-2): leaderboard
AIME 2024 and 2025, all 60 problems, with Python available: accuracy in percent by exact match on the integer answer, 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 (%; 60 problems, mean of 3 trials). Source: arxiv.org. Saturation forecast: Estimated already saturated. 8 models tracked.
