Every score
one row per source and configuration — nothing averaged away
| Benchmark | Score | Configuration | Source | Run |
|---|---|---|---|---|
| SWE-Bench verified | 72.7 | default · mini-SWE-agent · 2 runs | SWE-bench | — |
| ↳ | 71.4 | high · mini-SWE-agent | SWE-bench | — |
| Settings differ by 1.3 points on this benchmark. | ||||
The leading figure for a benchmark is the median across its configurations, so one heroic high-effort run cannot set the number.
