Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
Nemotron Ultra 253B is clearly ahead on the aggregate, 48 to 27. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Nemotron Ultra 253B's sharpest advantage is in coding, where it averages 33.7 against 6.2. The single biggest benchmark swing on the page is SWE-bench Pro, 38 to 5.
Nemotron Ultra 253B is the reasoning model in the pair, while Ministral 3 3B 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. Ministral 3 3B gives you the larger context window at 128K, compared with 32K for Nemotron Ultra 253B.
Pick Nemotron Ultra 253B if you want the stronger benchmark profile. Ministral 3 3B only becomes the better choice if you need the larger 128K context window or you would rather avoid the extra latency and token burn of a reasoning model.
