Pick Grok 4.1 if you want the stronger benchmark profile. Qwen3.5-35B-A3B only becomes the better choice if you want the cheaper token bill or you want the stronger reasoning-first profile.
Grok 4.1 is clearly ahead on the aggregate, 91 to 67. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Grok 4.1's sharpest advantage is in reasoning, where it averages 93 against 59. The single biggest benchmark swing on the page is SuperGPQA, 95% to 63.4%.
Grok 4.1 is also the more expensive model on tokens at $3.00 input / $15.00 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Qwen3.5-35B-A3B. That is roughly Infinityx on output cost alone. Qwen3.5-35B-A3B is the reasoning model in the pair, while Grok 4.1 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. Grok 4.1 gives you the larger context window at 1M, compared with 262K for Qwen3.5-35B-A3B.
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.
