Pick o1-preview 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.
o1-preview is clearly ahead on the aggregate, 72 to 50. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
o1-preview's sharpest advantage is in knowledge, where it averages 72.7 against 30. The single biggest benchmark swing on the page is GPQA, 30% to 90%.
o1-preview 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. o1-preview gives you the larger context window at 200K, 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.
