GPT-4.1 vs Nemotron 3 Nano Omni 30B A3B

Pick GPT-4.1 if you want the stronger benchmark profile. Nemotron 3 Nano Omni 30B A3B only becomes the better choice if knowledge is the priority or you want the cheaper token bill.

GPT-4.1 is clearly ahead on the provisional aggregate, 57 to 48. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

GPT-4.1's sharpest advantage is in instruction following, where it averages 87.4 against 74.2. The single biggest benchmark swing on the page is GPQA, 66.3% to 72.2%. Nemotron 3 Nano Omni 30B A3B does hit back in knowledge, so the answer changes if that is the part of the workload you care about most.

GPT-4.1 is also the more expensive model on tokens at $2.00 input / $8.00 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 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 gives you the larger context window at 1M, compared with 256K for Nemotron 3 Nano Omni 30B A3B.
