Grok Code Fast 1· Qwen3.5-122B-A10B

Quick Verdict

Pick Qwen3.5-122B-A10B if you want the stronger benchmark profile. Grok Code Fast 1 only becomes the better choice if reasoning is the priority or you would rather avoid the extra latency and token burn of a reasoning model.

Qwen3.5-122B-A10B is clearly ahead on the aggregate, 71 to 56. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

Qwen3.5-122B-A10B's sharpest advantage is in knowledge, where it averages 81.6 against 49. The single biggest benchmark swing on the page is MMMU-Pro, 40% to 76.9%. Grok Code Fast 1 does hit back in reasoning, so the answer changes if that is the part of the workload you care about most.

Qwen3.5-122B-A10B is the reasoning model in the pair, while Grok Code Fast 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. Qwen3.5-122B-A10B gives you the larger context window at 262K, compared with 256K for Grok Code Fast 1.

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.
