Harbor Adapters - CRUST-Bench (Terminus-2): leaderboard

CRUST-Bench, translating real-world C repositories into safe Rust against hand-written Rust interfaces, all 100 tasks: the percentage of projects whose translation passes the correctness tests (cargo test), 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 (%; 100 tasks, mean of 3 trials). Source: arxiv.org. Saturation forecast: Estimated already saturated. 8 models tracked.
