Quick Verdict

Pick Qwen3.5-122B-A10B if you want the stronger benchmark profile. o3-mini only becomes the better choice if reasoning is the priority.

Qwen3.5-122B-A10B is clearly ahead on the aggregate, 71 to 65. 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 54.1. The single biggest benchmark swing on the page is SWE-bench Verified, 49.3% to 72%. o3-mini does hit back in reasoning, so the answer changes if that is the part of the workload you care about most.

o3-mini is also the more expensive model on tokens at $1.10 input / $4.40 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Qwen3.5-122B-A10B. That is roughly Infinityx on output cost alone. Qwen3.5-122B-A10B gives you the larger context window at 262K, compared with 200K for o3-mini.

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.
