Pick Grok Code Fast 1 if you want the stronger benchmark profile. 1-bit Bonsai 4B only becomes the better choice if its workflow or ecosystem matters more than the raw scoreboard.
Grok Code Fast 1 is clearly ahead on the aggregate, 56 to 44. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Grok Code Fast 1's sharpest advantage is in reasoning, where it averages 63.3 against 41.4. The single biggest benchmark swing on the page is GPQA, 28.7% to 63%.
Grok Code Fast 1 gives you the larger context window at 256K, compared with 32K for 1-bit Bonsai 4B.
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.
