GPT-5.4· Qwen3.5-122B-A10B

Quick Verdict

Pick GPT-5.4 if you want the stronger benchmark profile. Qwen3.5-122B-A10B only becomes the better choice if coding is the priority or you want the cheaper token bill.

GPT-5.4 is clearly ahead on the aggregate, 82 to 71. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

GPT-5.4's sharpest advantage is in reasoning, where it averages 87.7 against 60.2. The single biggest benchmark swing on the page is SuperGPQA, 96% to 67.1%. Qwen3.5-122B-A10B does hit back in coding, so the answer changes if that is the part of the workload you care about most.

GPT-5.4 is also the more expensive model on tokens at $2.50 input / $15.00 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 gives you the larger context window at 1.05M, 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.
