Gemini 2.5 Pro vs GPT-4.1

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

Gemini 2.5 Pro is clearly ahead on the aggregate, 72 to 43. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

Gemini 2.5 Pro's sharpest advantage is in mathematics, where it averages 83.1 against 26.4. The single biggest benchmark swing on the page is AIME 2024, 86 to 26.4. GPT-4.1 does hit back in knowledge, so the answer changes if that is the part of the workload you care about most.

GPT-4.1 is also the more expensive model on tokens at $2.00 input / $8.00 output per 1M tokens, versus $1.25 input / $5.00 output per 1M tokens for Gemini 2.5 Pro.

Quick Verdict

Pick Gemini 2.5 Pro if you want the stronger benchmark profile. GPT-4.1 only becomes the better choice if knowledge is the priority.
