Side-by-side benchmark comparison across knowledge, coding, math, and reasoning.
MiMo-V2-Flash is clearly ahead on the aggregate, 71 to 43. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
MiMo-V2-Flash's sharpest advantage is in mathematics, where it averages 79.5 against 26.4. The single biggest benchmark swing on the page is AIME 2024, 81 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.
MiMo-V2-Flash is the reasoning model in the pair, while GPT-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. GPT-4.1 gives you the larger context window at 1M, compared with 128K for MiMo-V2-Flash.
Pick MiMo-V2-Flash if you want the stronger benchmark profile. GPT-4.1 only becomes the better choice if knowledge is the priority or you need the larger 1M context window.
