Side-by-side benchmark comparison across knowledge, coding, math, and reasoning.
Grok 4.1 is clearly ahead on the aggregate, 89 to 51. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Grok 4.1's sharpest advantage is in coding, where it averages 80.3 against 41. The single biggest benchmark swing on the page is SWE-bench Verified, 77 to 41.
o1 is also the more expensive model on tokens at $15.00 input / $60.00 output per 1M tokens, versus $3.00 input / $15.00 output per 1M tokens for Grok 4.1. That is roughly 4.0x on output cost alone. o1 is the reasoning model in the pair, while Grok 4.1 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. Grok 4.1 gives you the larger context window at 1M, compared with 200K for o1.
Pick Grok 4.1 if you want the stronger benchmark profile. o1 only becomes the better choice if you want the stronger reasoning-first profile.
