Pick 1-bit Bonsai 8B if you want the stronger benchmark profile. GLM-4.5 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 41. 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 42.1. The single biggest benchmark swing on the page is MuSR, 50% to 33%. GLM-4.5 does hit back in knowledge, so the answer changes if that is the part of the workload you care about most.
GLM-4.5 gives you the larger context window at 128K, 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.
