How to read this leaderboard
Compare the published configurations as complete evaluation systems. The source can combine a base model, agent scaffold, tools, budget, and inference setting in each result.
Operator receipt: 18 sourced rows are currently displayable on this page; the leading published row is Opus 5 (Claude Code) xhigh at 99.4%.
Honest limit: This Scale table is display-only context, not benchmark provenance or a weighted model-only comparison.
How BenchLM shows SWE-Bench Pro V2 Full
BenchLM mirrors 18 published rows from Scale Labs’ public SWE-Bench Pro V2 Full leaderboard, captured on November 12, 2026 snapshot.
The table is display only. It is useful context for a published agent or model configuration, but it does not enter BenchLM’s overall or category rankings.
Snapshot
The published SWE-Bench Pro V2 Full snapshot places Opus 5 (Claude Code) xhigh first at 99.4%. The third row is 0.3 points behind. The broader top-10 range is 3.6 points, so many of the published results sit in a relatively narrow band.
18 models have been evaluated on SWE-Bench Pro V2 Full. The benchmark falls in the Coding category. We keep external benchmark mirrors separate from the weighted global scoring system, so these results remain source-specific evidence. SWE-Bench Pro V2 Full is currently displayed for reference but excluded from the scoring formula, so it does not directly affect overall rankings.
