GPT-5.4 mini· Qwen3.5-122B-A10B

Quick Verdict

Pick Qwen3.5-122B-A10B if you want the stronger benchmark profile. GPT-5.4 mini only becomes the better choice if agentic is the priority or you need the larger 400K context window.

Qwen3.5-122B-A10B has the cleaner overall profile here, landing at 71 versus 68. It is a real lead, but still close enough that category-level strengths matter more than the headline number.

Qwen3.5-122B-A10B's sharpest advantage is in knowledge, where it averages 81.6 against 57.4. The single biggest benchmark swing on the page is OSWorld-Verified, 72.1% to 58%. GPT-5.4 mini does hit back in agentic, so the answer changes if that is the part of the workload you care about most.

GPT-5.4 mini is also the more expensive model on tokens at $0.75 input / $4.50 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. GPT-5.4 mini gives you the larger context window at 400K, compared with 262K for Qwen3.5-122B-A10B.

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.
