Quick Verdict

Pick GPT-5.4 Pro if you want the stronger benchmark profile. GPT-4.1 only becomes the better choice if knowledge is the priority or you want the cheaper token bill.

GPT-5.4 Pro is clearly ahead on the provisional aggregate, 92 to 60. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

GPT-5.4 Pro is also the more expensive model on tokens at $30.00 input / $180.00 output per 1M tokens, versus $2.00 input / $8.00 output per 1M tokens for GPT-4.1. That is roughly 22.5x on output cost alone. GPT-5.4 Pro is the reasoning model in the pair, while GPT-4.1 is not. That usually helps on harder chain-of-thought-heavy tests, but it can also mean more latency and more token spend in real use. GPT-5.4 Pro gives you the larger context window at 1.05M, compared with 1M for GPT-4.1.
