CWE-bench v1 - Language - C/C++ - Programmatic Pass@1: leaderboard

Collinear CWE-bench archived v1, Language - C/C++ - Programmatic Pass@1, reported as a percentage. 120 private audit-and-patch tasks; four rollouts per task at high reasoning, one hour each; timeouts graded on code at timeout. Native model-specific harnesses. Programmatic success requires exploit blocked and existing tests passing. Separate majority panel of three rubric-based agentic judges checks correctness, happy-path, generalization, integrity and soundness; any failed axis rejects a fix. Pass@1 and Pass@4 remain separate. This is archived Collinear v1, not the Artificial Analysis Stirrup two-hour implementation or CWE-bench v2. Source: https://cwe-bench.com/v1
