About
Grok Build 0.1 is xAI's agentic coding model for the Grok Build CLI and public API beta. It launched for the CLI on May 14, 2026, and for public API beta access on May 29, 2026. It replaces grok-code-fast-1 for current coding-agent workflows, supports text and image input, tool calling, structured outputs, always-on reasoning, prompt caching, and a 256K-token context window; xAI self-reports 70.8% on SWE-bench Verified using its internal harness.
Grok Build 0.1 is a proprietary model in the Grok 4 family. The structured metadata tracks a 256k-token context window, multimodal input, reasoning, function calling, tool use, and structured outputs. This page tracks provider routes through xAI Console, Vercel AI Gateway, and OpenRouter, with the cheapest tracked route listed at $1 input and $2 output per 1M tokens.
