SWE-bench Live C/C++ (66 tasks, SWE-agent): leaderboard
SWE-bench-Live's C/C++ split (Microsoft, 2026 multi-language update): recent GitHub issues from C/C++ repositories, built into runnable environments by the RepoLaunch pipeline and graded by the repository's tests. This board is the 66-task snapshot under the SWE-agent harness, scored as the percentage of tasks resolved; higher is better. The split grows, so each snapshot size is its own board.
