3/8 categoriesGPT-5 (medium)· Qwen3.5-122B-A10B
Pick GPT-5 (medium) if you want the stronger benchmark profile. Qwen3.5-122B-A10B only becomes the better choice if knowledge is the priority or you need the larger 262K context window.
GPT-5 (medium) is clearly ahead on the aggregate, 76 to 71. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
GPT-5 (medium)'s sharpest advantage is in reasoning, where it averages 82.1 against 60.2. The single biggest benchmark swing on the page is Terminal-Bench 2.0, 77% to 49.4%. Qwen3.5-122B-A10B does hit back in knowledge, 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 128K for GPT-5 (medium).
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.
