Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
DeepSeek V3 finishes one point ahead overall, 25 to 24. 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.
DeepSeek V3's sharpest advantage is in mathematics, where it averages 90.2 against 48. The single biggest benchmark swing on the page is MMLU, 88.5% to 49%. Nemotron Ultra 253B does hit back in reasoning, so the answer changes if that is the part of the workload you care about most.
Nemotron Ultra 253B is the reasoning model in the pair, while DeepSeek V3 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. DeepSeek V3 gives you the larger context window at 128K, compared with 32K for Nemotron Ultra 253B.
Pick DeepSeek V3 if you want the stronger benchmark profile. Nemotron Ultra 253B only becomes the better choice if reasoning is the priority or you want the stronger reasoning-first profile.
