Nemotron 3 Ultra 500B vs LFM2-24B-A2B

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

Nemotron 3 Ultra 500B is clearly ahead on the aggregate, 64 to 38. 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 77.2 against 46.6. The single biggest benchmark swing on the page is MRCRv2, 85 to 45.

Nemotron 3 Ultra 500B 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. Nemotron 3 Ultra 500B gives you the larger context window at 10M, compared with 32K for LFM2-24B-A2B.

Quick Verdict

Pick Nemotron 3 Ultra 500B 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.
