Harbor Adapters - Terminal-Bench 2.0 (Terminus-2): leaderboard

Terminal-Bench 2.0, realistic command-line tasks such as build configuration, debugging and system administration, all 89: the percentage of tasks that pass the upstream test scripts, 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: Pass rate (%; 89 tasks, mean of 3 trials). Source: arxiv.org. Saturation forecast: Around February 2027. 8 models tracked.
