SWE-Cycle - Test Generation: leaderboard
Metric: Score (%): the mean of the static and dynamic scores (SWE-Judge (Claude Opus 4.5 agent) static code review and dynamic execution, each scored 0, 1 or 2, normalized to 0-1), on the 489 SWE-Cycle issues (225 SWE-bench Verified, 203 SWE-bench Pro, 61 SWE-bench Multilingual, filtered for contamination, lifecycle complexity and reliable tests); isolated TestGen: write tests that isolate the issue in a patched codebase (90 minutes); agents run in the OpenCode harness in isolated Docker containers; higher is better.
