Pick Nemotron 3 Ultra 500B if you want the stronger benchmark profile. 1-bit Bonsai 8B only becomes the better choice if you would rather avoid the extra latency and token burn of a reasoning model.
Nemotron 3 Ultra 500B is clearly ahead on the aggregate, 60 to 50. 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 79.1 against 50. The single biggest benchmark swing on the page is GPQA, 30% to 73%.
Nemotron 3 Ultra 500B is the reasoning model in the pair, while 1-bit Bonsai 8B 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 64K for 1-bit Bonsai 8B.
BenchLM keeps the benchmark table and the operator tradeoffs on the same page so a better score does not hide a materially slower, pricier, or smaller-context model.
Runtime metrics show N/A when BenchLM does not have a sourced snapshot for that exact model. The scoring rules and freshness policy are documented on the methodology page.
