Why this result
GPT-5.4 Pro has the cleaner BenchAlign overall profile here, landing at 60.89 versus 58.01. It is a real lead, but still close enough that category-level strengths matter more than the headline number.
GPT-5.4 Pro's sharpest advantage is in mathematics, where it averages 46.9 against 6.4. The single biggest benchmark swing on the page is FrontierMath v2 (Tiers 1-3), 50.000% to 8.481%.
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 235B 2507 (Reasoning). That is roughly Infinityx on output cost alone. GPT-5.4 Pro gives you the larger context window at 1.05M, compared with 128K for Qwen3 235B 2507 (Reasoning).
