Qwen2.5-1M· Qwen3.5-35B-A3B

Quick Verdict

Pick Qwen3.5-35B-A3B if you want the stronger benchmark profile. Qwen2.5-1M only becomes the better choice if reasoning is the priority or you need the larger 1M context window.

Qwen3.5-35B-A3B is clearly ahead on the aggregate, 67 to 62. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

Qwen3.5-35B-A3B's sharpest advantage is in coding, where it averages 72.6 against 45.1. The single biggest benchmark swing on the page is LiveCodeBench, 40% to 74.6%. Qwen2.5-1M does hit back in reasoning, so the answer changes if that is the part of the workload you care about most.

Qwen3.5-35B-A3B is the reasoning model in the pair, while Qwen2.5-1M 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. Qwen2.5-1M gives you the larger context window at 1M, compared with 262K for Qwen3.5-35B-A3B.

Decision framing

BenchLM keeps the benchmark table and the operator tradeoffs on the same page so a better score does not hide a materially slower, pricier, or smaller-context model.

Runtime metrics show N/A when BenchLM does not have a sourced snapshot for that exact model. The scoring rules and freshness policy are documented on the methodology page.
