Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
MiMo-V2-Flash finishes one point ahead overall, 66 to 65. 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.
MiMo-V2-Flash's sharpest advantage is in coding, where it averages 50 against 41.1. The single biggest benchmark swing on the page is MMMU-Pro, 78 to 66. Mercury 2 does hit back in reasoning, so the answer changes if that is the part of the workload you care about most.
Pick MiMo-V2-Flash if you want the stronger benchmark profile. Mercury 2 only becomes the better choice if reasoning is the priority.
