Harbor Adapters - SWE-bench Verified (Terminus-2): leaderboard

SWE-bench Verified, the human-curated set of real Python GitHub issues, here 100 of its 500 tasks: the percentage of issues the agent's patch resolves, judged by the repository's unit tests, 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: Resolved rate (%; 100 tasks, mean of 3 trials). Source: arxiv.org. Saturation forecast: Around February 2027. 8 models tracked.
