Pick Qwen3.5-122B-A10B if you want the stronger benchmark profile. o3-pro only becomes the better choice if reasoning is the priority.
Qwen3.5-122B-A10B is clearly ahead on the aggregate, 71 to 67. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Qwen3.5-122B-A10B's sharpest advantage is in coding, where it averages 76.3 against 49.5. The single biggest benchmark swing on the page is LiveCodeBench, 44% to 78.9%. o3-pro does hit back in reasoning, so the answer changes if that is the part of the workload you care about most.
Qwen3.5-122B-A10B gives you the larger context window at 262K, compared with 200K for o3-pro.
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.
