Harbor Adapters - CompileBench (Terminus-2): leaderboard

CompileBench, real-world build tasks (dependency resolution, legacy code, static linking, ARM64 and Windows cross-compilation), all 15: the percentage of builds 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 (%; 15 tasks, mean of 3 trials). Source: arxiv.org. Saturation forecast: Estimated already saturated. 8 models tracked.
