SWE-Explore - Context Efficiency: 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 the percent of returned lines inside the core or optional ground-truth context; higher is better.

Metric: Context efficiency (%; share of returned lines inside the core or optional ground-truth context) 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. Source: arxiv.org. Saturation forecast: Around February 2027. 6 models tracked.
