GPT-4.1 mini vs Nemotron 3 Nano Omni 30B A3B

Pick Nemotron 3 Nano Omni 30B A3B if you want the stronger benchmark profile. GPT-4.1 mini only becomes the better choice if instruction following is the priority or you need the larger 1M context window.

Nemotron 3 Nano Omni 30B A3B is clearly ahead on the provisional aggregate, 56 to 46. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

Nemotron 3 Nano Omni 30B A3B's sharpest advantage is in coding, where it averages 53.5 against 23.6. The single biggest benchmark swing on the page is GPQA, 64.2% to 72.2%. GPT-4.1 mini does hit back in instruction following, 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 Nano Omni 30B A3B. That is roughly Infinityx on output cost alone. Nemotron 3 Nano Omni 30B A3B 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 256K for Nemotron 3 Nano Omni 30B A3B.
