Pick GPT-5.4 Pro if you want the stronger benchmark profile. Qwen3.5-122B-A10B only becomes the better choice if you want the cheaper token bill.
GPT-5.4 Pro is clearly ahead on the aggregate, 92 to 71. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
GPT-5.4 Pro's sharpest advantage is in reasoning, where it averages 95.7 against 60.2. The single biggest benchmark swing on the page is Terminal-Bench 2.0, 90% to 49.4%.
GPT-5.4 Pro is also the more expensive model on tokens at $30.00 input / $180.00 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 Pro gives you the larger context window at 1.05M, compared with 262K for Qwen3.5-122B-A10B.
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.
