Gemini 3.1 Flash-Lite vs Nemotron 3 Nano Omni 30B A3B

Pick Nemotron 3 Nano Omni 30B A3B if you want the stronger benchmark profile. Gemini 3.1 Flash-Lite only becomes the better choice if you need the larger 1M context window or you would rather avoid the extra latency and token burn of a reasoning model.

Nemotron 3 Nano Omni 30B A3B is clearly ahead on the provisional aggregate, 56 to 49. 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 multimodal & grounded, where it averages 76.3 against 73.2. The single biggest benchmark swing on the page is CharXiv, 73.2% to 76.3%.

Gemini 3.1 Flash-Lite is also the more expensive model on tokens at $0.25 input / $1.50 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 Gemini 3.1 Flash-Lite 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. Gemini 3.1 Flash-Lite gives you the larger context window at 1M, compared with 256K for Nemotron 3 Nano Omni 30B A3B.
