Grok Build
xAI's open-source terminal coding agent that reads and edits codebases, runs commands, and spawns up to eight subagents.
Overview
Grok Build is xAI's terminal-based coding agent harness and TUI, introduced in July 2026 as an early beta limited to SuperGrok Heavy. It left beta at v1.0 on August 7, 2026 and is now open source under Apache 2.0 (github.com/xai-org/grok-build), reading a codebase, editing files, running commands, and spawning up to eight subagents in isolated git worktrees. As of September 2026 it is available on every plan on web and mobile, and a fast standalone model, Grok Build 0.1, entered public beta on the xAI API.
