Side-by-side benchmark comparison across knowledge, coding, math, and reasoning.
GPT-5.4 is clearly ahead on the aggregate, 93 to 33. 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 mathematics, where it averages 98 against 86. The single biggest benchmark swing on the page is GPQA, 98 to 79.
o1-pro is also the more expensive model on tokens at $150.00 input / $600.00 output per 1M tokens, versus $2.50 input / $15.00 output per 1M tokens for GPT-5.4. That is roughly 40.0x on output cost alone. GPT-5.4 gives you the larger context window at 1.05M, compared with 200K for o1-pro.
Pick GPT-5.4 if you want the stronger benchmark profile. o1-pro only becomes the better choice if its workflow or ecosystem matters more than the raw scoreboard.
