Software Engineering Benchmark Verified (SWE-bench Verified)
We show this table for reference; we do not rank on it.
Claude Opus 5 has the highest reported SWE-bench Verified score at 96%, ahead of Claude Mythos 5 (95.5%) and Claude Fable 5 (95%) among 111 models. We compile the table from provider self-reports and secondary reports and keep it for display only; it does not affect overall rankings.
SWE-bench Verified tests patches for 500 human-filtered GitHub issues. A score measures how many tasks an evaluated model-and-agent setup resolved; the model name alone does not identify that setup.

SWE-bench Verified*
BenchLM stores this chart-specific SWE-bench Verified row separately because Arcee notes all models were evaluated in mini-swe-agent-v2.

How to read this leaderboard
SWE-bench Verified is a 500-task subset of the original SWE-bench repository-repair benchmark. The official leaderboard separates agent submissions from the Bash Only view, where models use the same mini-SWE-agent environment.
Variant check: Verified, Lite, Multilingual, and Pro use different task sets. Keep the benchmark version, scaffold, tool budget, and retry policy with the score. A higher percentage on another version is not a like-for-like improvement.
Use this table to inspect published repository-repair results. We moved SWE-bench Verified to display only in BenchAlign v5.6; its published percentages do not contribute to the current public ranking. Pair it with newer repository tasks and a test on your own codebase.
Operator receipt: 111 sourced rows are currently displayable on this page; the leading published row is Claude Opus 5 at 96%.
Honest limit: Provider-reported scores can use different agents and budgets. Catalog API prices and context limits describe the model, not the cost or context used in a benchmark run. Missing setup fields remain unreported.
Among the reported SWE-bench Verified rows, Claude Opus 5 is first at 96%. The third row is 1.0 points behind. The broader top-10 range is 13.6 points, so the table still separates the published systems.
111 models have been evaluated on SWE-bench Verified. The benchmark falls in the Coding category. SWE-bench Verified is currently displayed for reference but excluded from the scoring formula, so it does not directly affect overall rankings. We moved it to display only in BenchAlign v5.6 because its tests are contaminated and saturated.
