SWE-Explore - nDCG@500: leaderboard
SWE-Explore (2026) isolates repository exploration for coding agents: for each of 848 issues from 203 repositories in 10 languages the explorer returns its five most relevant code regions, scored against line-level context distilled from successful repair trajectories, here with each LLM driving the Mini-SWE-Agent scaffold. This board is ranking quality under a 500-line budget, nDCG@500 on a 0-100 scale; higher is better.
Metric: nDCG@500 (0-100) (line-budgeted ranking gain, 500-line budget, normalized to the best attainable ordering) on 848 repository-exploration instances (issues from 203 repositories in 10 languages): given the repository and issue, the explorer returns five ranked code regions, scored against line-level core context distilled from independent successful repair trajectories; the Mini-SWE-Agent scaffold with each LLM; higher is better.
