Pick Qwen3.7 Plus if you want the stronger benchmark profile. Claude Opus 4.5 only becomes the better choice if multilingual is the priority or you would rather avoid the extra latency and token burn of a reasoning model.
Why this result
Qwen3.7 Plus has the cleaner BenchAlign overall profile here, landing at 67.22 versus 64.22. It is a real lead, but still close enough that category-level strengths matter more than the headline number.
Qwen3.7 Plus's sharpest advantage is in mathematics, where it averages 92.9 against 57.5. The single biggest benchmark swing on the page is IFBench, 58% to 79.1%. Claude Opus 4.5 does hit back in multilingual, so the answer changes if that is the part of the workload you care about most.
Qwen3.7 Plus is the reasoning model in the pair, while Claude Opus 4.5 is not. That usually helps on harder chain-of-thought-heavy tests, but it can also mean more latency and more token spend in real use. Qwen3.7 Plus gives you the larger context window at 1M, compared with 200K for Claude Opus 4.5.
