Pick o1-pro if you want the stronger benchmark profile. GPT-4.1 mini only becomes the better choice if you want the cheaper token bill or you need the larger 1M context window.
Confidence note. This is a partial-evidence comparison with 2 shared benchmark results across 1 evidence category; 1 of 8 categories currently have scoreable aggregates for both models. Treat the verdict as directional until coverage is more balanced.
Why this result
o1-pro has the cleaner BenchAlign overall profile here, landing at 45.94 versus 44.19. It is a real lead, but still close enough that category-level strengths matter more than the headline number.
o1-pro's sharpest advantage is in knowledge, where it averages 79 against 64.2. The single biggest benchmark swing on the page is GPQA, 64.2% to 79%.
o1-pro is also the more expensive model on tokens at $150.00 input / $600.00 output per 1M tokens, versus $0.40 input / $1.60 output per 1M tokens for GPT-4.1 mini. That is roughly 375.0x on output cost alone. o1-pro is the reasoning model in the pair, while GPT-4.1 mini 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-4.1 mini gives you the larger context window at 1M, compared with 200K for o1-pro.
