GPT-5.4 Pro vs o1-pro

Side-by-side benchmark comparison across knowledge, coding, math, and reasoning.

GPT-5.4 Pro is clearly ahead on the aggregate, 94 to 33. 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 mathematics, where it averages 98 against 86. The single biggest benchmark swing on the page is GPQA, 99 to 79.

o1-pro is also the more expensive model on tokens at $150.00 input / $600.00 output per 1M tokens, versus $30.00 input / $180.00 output per 1M tokens for GPT-5.4 Pro. That is roughly 3.3x on output cost alone. GPT-5.4 Pro gives you the larger context window at 1.05M, compared with 200K for o1-pro.

Quick Verdict

Pick GPT-5.4 Pro 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.
