xAI's Grok Build 0.1 is now accessible via Vercel AI Gateway, targeting agentic coding workflows. The model is in early access beta, has no configurable reasoning effort, and ships with no non-reasoning mode. It is the same model powering the Grok Build CLI app.
To call it, set the model identifier to xai/grok-build-0.1 in Vercel's AI SDK. The Gateway layer wraps it with unified API access, usage and cost tracking, automatic retries, failover, custom reporting, observability hooks, and Bring Your Own Key support.
The original changelog is worth reading for the specifics on provider routing behavior and how the Gateway's uptime guarantees stack against direct provider access. A model playground and leaderboard are live if you want to benchmark it before committing.
