Side-by-side benchmark comparison across knowledge, coding, math, and reasoning.
GPT-4.1 has the cleaner overall profile here, landing at 43 versus 40. It is a real lead, but still close enough that category-level strengths matter more than the headline number.
GPT-4.1's sharpest advantage is in knowledge, where it averages 78.3 against 35.8. The single biggest benchmark swing on the page is MMLU, 90.2 to 42. Grok 3 [Beta] 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 128K for Grok 3 [Beta].
Pick GPT-4.1 if you want the stronger benchmark profile. Grok 3 [Beta] only becomes the better choice if mathematics is the priority.
