Frequently asked questions
How does Grok Code Fast 1 perform overall in AI benchmarks?
Grok Code Fast 1 ranks #209 out of 230 models on the public BenchAlign leaderboard, with a score of 37.85/100. Its evidence status is Supported, and this profile shows 1 source-displayable benchmark row. The label describes evidence depth, not a provider quality claim; inspect category rows before choosing a workload.
Is Grok Code Fast 1 good for coding and programming?
Grok Code Fast 1 ranks #140 out of 148 eligible models for coding and programming, with a public category score of 33.7/100. Higher-ranked alternatives are available for workloads where this category decides the choice. Check the underlying rows before treating the aggregate as a workload guarantee.
Does Grok Code Fast 1 have full benchmark coverage on BenchLM?
No. Grok Code Fast 1 currently has 12 source-displayable rows across 416 tracked benchmark slots. The profile exposes published, non-generated evidence and leaves missing categories blank until an exact evaluation is available. Coverage describes how much was measured; it is not a penalty added to an individual benchmark result.
What is the context window size of Grok Code Fast 1?
Grok Code Fast 1 has a reported context window of 256K in the exact-model catalog record. The value stays visible, but the profile marks its source link as unavailable instead of presenting it as directly documented. Maximum output length remains separate because providers often publish a different limit.
