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 38. 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 18. The single biggest benchmark swing on the page is SWE-bench Pro, 38 to 19.
Nemotron Ultra 253B is the reasoning model in the pair, while LFM2-24B-A2B 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.
Pick Nemotron Ultra 253B if you want the stronger benchmark profile. LFM2-24B-A2B only becomes the better choice if you would rather avoid the extra latency and token burn of a reasoning model.
