Score in Context
What these scores mean
The multilingual score blends cross-language comprehension and generation benchmarks like MGSM and MMLU-ProX. It is the closest measured proxy for translation strength BenchLM tracks.
Known limitations
Benchmarks over-represent high-resource languages. For low-resource pairs, dialects, or domain terminology (legal, medical), run your own evaluation set — leaderboard gaps do not transfer reliably.
About this ranking
Ranking data as of October 29, 2026
Translation quality tracks the multilingual category: benchmarks that test comprehension and generation across languages. Scores here say little about a specific language pair, idiom, or domain terminology, so test your own pairs.
Unless noted otherwise, ranking surfaces on this page use BenchLM’s provisional leaderboard lane rather than the stricter sourced-only verified leaderboard.
Qwen3.7 Max leads this ranking with a score of 100, followed by Claude Opus 4.5 (96.5) and Qwen3.7 Plus (95.7). There is meaningful separation between the top models, suggesting genuine performance differences.
The best open-weight option is Qwen3.5 397B (ranked #5 with a score of 93.8). While proprietary models lead, open-weight options are within striking distance for teams willing to trade a few points of performance for full model control.

Questions
What is the best LLM for translation?
The first row of the multilingual table above is the current answer, and the table recomputes on every data refresh. Shortlist the top rows, check how far apart their scores are, and weigh price and ecosystem only when they are close. For low-resource pairs, dialects, or legal and medical terminology, run your own test set before committing.
Are LLMs better than Google Translate?
For context-heavy translation — documents, marketing copy, anything where tone matters — frontier LLMs generally produce more natural output because they use surrounding context and follow style instructions. For quick single sentences, dedicated translation tools remain faster and cheaper.
What is the best open-source model for translation?
Alibaba's Qwen rows are the strongest open-weight multilingual performers BenchLM tracks, which fits their heavily multilingual training focus. See the Qwen rankings and the open-source leaderboard for current scores per model.
How should I evaluate translation quality myself?
Build a 30-50 segment test set from your real content across your target pairs, translate with 2-3 shortlisted models, and have a native speaker rank blind. Benchmark scores shortlist correctly, but domain terminology and tone preferences are yours to verify.
