Pick Nemotron 3 Ultra if you want the stronger benchmark profile. GPT-4.1 mini only becomes the better choice if knowledge is the priority or you would rather avoid the extra latency and token burn of a reasoning model.
Confidence note. This is a partial-evidence comparison with 19 shared benchmark results across 6 evidence categories; 3 of 8 categories currently have scoreable aggregates for both models. Treat the verdict as directional until coverage is more balanced.
Why this result
Nemotron 3 Ultra is clearly ahead on the provisional aggregate, 60 to 42. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Nemotron 3 Ultra's sharpest advantage is in coding, where it averages 58.3 against 23.6. The single biggest benchmark swing on the page is SWE-bench Verified, 23.6% to 71.9%. GPT-4.1 mini does hit back in knowledge, so the answer changes if that is the part of the workload you care about most.
GPT-4.1 mini is also the more expensive model on tokens at $0.40 input / $1.60 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Nemotron 3 Ultra. That is roughly Infinityx on output cost alone. Nemotron 3 Ultra 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.
