ComBench (Compilation Error Repair): leaderboard

Metric: Semantic correctness (%) of patches for the 200 reproducible real CI compilation errors from Bitcoin, OpenSSL, RocksDB and LLVM: the patch compiles without new errors and, by the authors' manual analysis, matches the developer's intended semantics, single-shot repair with perfect fault localization: the prompt gives the full source of the failing file and of every file the developer's fix modified plus the raw compiler diagnostics, and the model answers once with a cross-file search-and-replace patch (one retry when no patch applies), temperature 0.2; higher is better. Source: arxiv.org. Saturation forecast: Around July 2027. 9 models tracked.
