Side-by-side benchmark comparison across knowledge, coding, math, and reasoning.
GPT-4.1 finishes one point ahead overall, 43 to 42. That is enough to call, but not enough to treat as a blowout. This matchup comes down to a few meaningful edges rather than one model dominating the board.
GPT-4.1's sharpest advantage is in knowledge, where it averages 78.3 against 37.3. The single biggest benchmark swing on the page is MMLU, 90.2 to 45. Gemma 3 27B does hit back in mathematics, so the answer changes if that is the part of the workload you care about most.
GPT-4.1 gives you the larger context window at 1M, compared with 32K for Gemma 3 27B.
Pick GPT-4.1 if you want the stronger benchmark profile. Gemma 3 27B only becomes the better choice if mathematics is the priority.
