Pick GPT-5.4 Pro if you want the stronger benchmark profile. Command A+ only becomes the better choice if you want the cheaper token bill.
Confidence note. This is a partial-evidence comparison with 2 shared benchmark results across 2 evidence categories; 1 of 8 categories currently have scoreable aggregates for both models. Treat the verdict as directional until coverage is more balanced.
Why this result
GPT-5.4 Pro is clearly ahead on the BenchAlign aggregate, 60.89 to 47.51. 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 multimodal & grounded, where it averages 94 against 59.3. The single biggest benchmark swing on the page is MMMU-Pro, 63% to 94%.
GPT-5.4 Pro is also the more expensive model on tokens at $30.00 input / $180.00 output per 1M tokens, versus $2.50 input / $10.00 output per 1M tokens for Command A+. That is roughly 18.0x on output cost alone. GPT-5.4 Pro gives you the larger context window at 1.05M, compared with 128K for Command A+.
