Quick Verdict
Pick MiniCPM5-1B if you want the stronger benchmark profile. GPT-4.1 nano only becomes the better choice if instruction following is the priority or you need the larger 1M context window.
MiniCPM5-1B is clearly ahead on the provisional aggregate, 36 to 30. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
MiniCPM5-1B's sharpest advantage is in mathematics, where it averages 33.1 against 1. The single biggest benchmark swing on the page is IFEval, 83.2% to 80.4%. GPT-4.1 nano does hit back in instruction following, so the answer changes if that is the part of the workload you care about most.
MiniCPM5-1B is the reasoning model in the pair, while GPT-4.1 nano 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 nano gives you the larger context window at 1M, compared with 131K for MiniCPM5-1B.
