Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
Nemotron 3 Ultra 500B is clearly ahead on the aggregate, 37 to 23. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Nemotron 3 Ultra 500B's sharpest advantage is in reasoning, where it averages 69.9 against 21.7. The single biggest benchmark swing on the page is SimpleQA, 21.7% to 71%. Grok 3 Mini does hit back in knowledge, so the answer changes if that is the part of the workload you care about most.
Nemotron 3 Ultra 500B is the reasoning model in the pair, while Grok 3 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. Nemotron 3 Ultra 500B gives you the larger context window at 10M, compared with 128K for Grok 3 Mini.
Pick Nemotron 3 Ultra 500B if you want the stronger benchmark profile. Grok 3 Mini only becomes the better choice if knowledge is the priority or you would rather avoid the extra latency and token burn of a reasoning model.
