Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
MiMo-V2-Flash is clearly ahead on the aggregate, 66 to 30. 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 83.4 against 37. The single biggest benchmark swing on the page is HumanEval, 71 to 14.
MiMo-V2-Flash is the reasoning model in the pair, while LFM2.5-1.2B-Instruct 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. MiMo-V2-Flash gives you the larger context window at 128K, compared with 32K for LFM2.5-1.2B-Instruct.
Pick MiMo-V2-Flash if you want the stronger benchmark profile. LFM2.5-1.2B-Instruct only becomes the better choice if you would rather avoid the extra latency and token burn of a reasoning model.
