SWE-bench Multilingual
Multilingual SWE-bench suite evaluating software engineering issue resolution across repositories and languages beyond the original Python-heavy SWE-bench tasks. High benchmark score alone doesn't make a model the right pick — weigh it against pricing, API availability, and release date.

Configuration: Claude Opus 5 standard configuration
Notes: Vendor-reported. Source: p.149, Table 8.1.A. This multilingual suite is not the English SWE-bench Verified row.
Notes: Confidence: medium. DAT-4756 secondary-source score for Cursor Composer 2.5; compare directionally because Composer is a productized IDE agent.
Notes: Official LongCat-2.0 launch chart reports 77.33. Evaluator/harness details are not fully reproducible from public text. Confidence: confirmed for reported value, medium for reproducibility.
Notes: Confidence: medium. DAT-4756 comparison research; preserve harness caveat when comparing against Composer 2.5.
How to read this benchmark
This benchmark scores models where higher is better. Scores are useful for directional filtering and shortlisting — not for universal quality ranking. Prefer benchmarks closest to your workload, then validate the linked model pages for pricing, context window, and provider availability.
Trust this score when
- There is a fresh timestamped snapshot (or multiple snapshots) for this benchmark.
- The model list covers the same version family you can actually deploy today.
- Top candidates overlap with your required routing and feature requirements.
Be cautious when
- There is only one benchmark snapshot or the dataset appears stale.
- The benchmark metric direction is opposite of your decision objective.
- The score difference between options is narrow and likely within implementation variance.
