Quick Verdict
Pick GPT-4.1 mini if you want the stronger benchmark profile. MiniCPM5-1B only becomes the better choice if mathematics is the priority or you want the stronger reasoning-first profile.
GPT-4.1 mini is clearly ahead on the provisional aggregate, 42 to 36. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
GPT-4.1 mini's sharpest advantage is in instruction following, where it averages 88.5 against 58.5. The single biggest benchmark swing on the page is IFEval, 88.5% to 80.4%. MiniCPM5-1B does hit back in mathematics, 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 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. GPT-4.1 mini gives you the larger context window at 1M, compared with 131K for MiniCPM5-1B.
