Nemotron 3 Super 120B A12B vs Seed 1.6 Flash

Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.

Nemotron 3 Super 120B A12B is clearly ahead on the aggregate, 61 to 56. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

Nemotron 3 Super 120B A12B's sharpest advantage is in coding, where it averages 44.2 against 27.6. The single biggest benchmark swing on the page is SWE-bench Verified, 46 to 24. Seed 1.6 Flash does hit back in multimodal & grounded, so the answer changes if that is the part of the workload you care about most.

Seed 1.6 Flash is also the more expensive model on tokens at $0.08 input / $0.30 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Nemotron 3 Super 120B A12B. That is roughly Infinityx on output cost alone. Seed 1.6 Flash is the reasoning model in the pair, while Nemotron 3 Super 120B A12B 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.

Quick Verdict

Pick Nemotron 3 Super 120B A12B if you want the stronger benchmark profile. Seed 1.6 Flash only becomes the better choice if multimodal & grounded is the priority or you want the stronger reasoning-first profile.
