1-bit Bonsai 8B· DeepSeek V3.1 (Reasoning)

Quick Verdict

Pick 1-bit Bonsai 8B if you want the stronger benchmark profile. DeepSeek V3.1 (Reasoning) only becomes the better choice if knowledge is the priority or you need the larger 128K context window.

1-bit Bonsai 8B is clearly ahead on the aggregate, 50 to 43. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

1-bit Bonsai 8B's sharpest advantage is in mathematics, where it averages 66 against 41.1. The single biggest benchmark swing on the page is MuSR, 50% to 30%. DeepSeek V3.1 (Reasoning) does hit back in knowledge, so the answer changes if that is the part of the workload you care about most.

DeepSeek V3.1 (Reasoning) 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. DeepSeek V3.1 (Reasoning) gives you the larger context window at 128K, compared with 64K for 1-bit Bonsai 8B.

Decision framing

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.
