GPT-4o vs o1-pro

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

GPT-4o is clearly ahead on the aggregate, 60 to 33. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

o1-pro is also the more expensive model on tokens at $150.00 input / $600.00 output per 1M tokens, versus $2.50 input / $10.00 output per 1M tokens for GPT-4o. That is roughly 60.0x on output cost alone. o1-pro is the reasoning model in the pair, while GPT-4o 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. o1-pro gives you the larger context window at 200K, compared with 128K for GPT-4o.

Quick Verdict

Pick GPT-4o if you want the stronger benchmark profile. o1-pro only becomes the better choice if knowledge is the priority or you need the larger 200K context window.
