1-bit Bonsai 1.7B· Phi-4

Quick Verdict

Pick Phi-4 if you want the stronger benchmark profile. 1-bit Bonsai 1.7B only becomes the better choice if reasoning is the priority or you need the larger 32K context window.

Phi-4 finishes one point ahead overall, 40 to 39. That is enough to call, but not enough to treat as a blowout. This matchup comes down to a few meaningful edges rather than one model dominating the board.

Phi-4's sharpest advantage is in mathematics, where it averages 94.6 against 34.4. The single biggest benchmark swing on the page is MATH-500, 34.4% to 94.6%. 1-bit Bonsai 1.7B does hit back in reasoning, so the answer changes if that is the part of the workload you care about most.

1-bit Bonsai 1.7B gives you the larger context window at 32K, compared with 16K for Phi-4.

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.
