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 finishes one point ahead on BenchLM's provisional leaderboard, 48 to 47. That is enough to call, but not enough to treat as a blowout. This matchup comes down to a few meaningful edges rather than one model dominating the board.

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.
