GPT-4.1 mini vs o1-pro

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

GPT-4.1 mini has the cleaner overall profile here, landing at 35 versus 33. It is a real lead, but still close enough that category-level strengths matter more than the headline number.

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.

Quick Verdict

Pick GPT-4.1 mini if you want the stronger benchmark profile. o1-pro only becomes the better choice if mathematics is the priority or you want the stronger reasoning-first profile.
