Pick MiMo-V2.5 if you want the stronger benchmark profile. GPT-4.1 mini only becomes the better choice if you would rather avoid the extra latency and token burn of a reasoning model.
MiMo-V2.5 is clearly ahead on the provisional aggregate, 72 to 45. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
MiMo-V2.5's sharpest advantage is in coding, where it averages 56.1 against 23.6.
MiMo-V2.5 is the reasoning model in the pair, while GPT-4.1 mini 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-V2.5 is ahead on BenchLM's provisional leaderboard, 72 to 45.
MiMo-V2.5 has the edge for coding in this comparison, averaging 56.1 versus 23.6. GPT-4.1 mini stays close enough that the answer can still flip depending on your workload.
