Coding ranks #113. Particularly well-suited for software development and code generation tasks.
Validate before choosing
2 published rows leave some tracked benchmark slots empty. Independent runtime speed has not been measured.
Decision snapshot
Each value carries a field reference instead of floating alone. Markers compare this model with the current ranked and priced catalog; they are not absolute quality thresholds.

How much of this is verified
Coverage is split by category so a strong number never hides a thin evidence base. Verified means the row is tied to a published source; provisional rows remain visible but separate.

How to read this profile
The visual layer above carries the decisions. These notes preserve the model, ranking, coverage, and family context behind the numbers.
We track Grok Build 0.1, but the public leaderboard excludes this profile until enough non-generated benchmark coverage is available. Only published rows appear above.
Grok Build 0.1 is a proprietary model with a 256K context window. No explicit reasoning mode is documented in this profile.
Tracked from OpenRouter's May 20, 2026 model page and live models API. OpenRouter lists `x-ai/grok-build-0.1` as an early-access fast coding model for agentic software engineering workflows, with text+image input, text output, tool support, a 256K context window, and $1.00/M input / $2.00/M output pricing. BenchLM keeps this row unranked until benchmark-native or provider-native exact benchmark coverage is available.
2 of 437 tracked benchmark slots currently have displayable evidence. Missing categories stay blank.
Its strongest eligible category is Coding at #113, while its lowest eligible position is Agentic at #124. particularly well-suited for software development and code generation tasks.

Frequently asked questions
How does Grok Build 0.1 perform overall in AI benchmarks?
Grok Build 0.1 has 2 source-displayable benchmark rows, but it does not qualify for a public overall rank. The available rows remain visible by category without being converted into a site-wide score. Missing evidence stays blank instead of being estimated from an earlier model.
Is Grok Build 0.1 good for coding and programming?
Grok Build 0.1 ranks #113 out of 135 eligible models for coding and programming, with a public category score of 42.1/100. 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.
Is Grok Build 0.1 good for agentic tool use and computer tasks?
Grok Build 0.1 ranks #124 out of 131 eligible models for agentic tool use and computer tasks, with a public category score of 28.9/100. 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 Build 0.1 have full benchmark coverage on BenchLM?
No. Grok Build 0.1 currently has 2 source-displayable rows across 437 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 Build 0.1?
Grok Build 0.1 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.
Last updated August 18, 2026. Runtime fields remain blank until a sourced snapshot exists.
