Harbor Adapters - IneqMath (Terminus-2): leaderboard

IneqMath, multiple-choice questions on inequality bounds and relations, all 100 public development questions: accuracy in percent by exact match with an LLM-judge fallback, 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 (%; 100 questions, mean of 3 trials). Source: arxiv.org. Saturation forecast: Estimated already saturated. 8 models tracked.
