Grok Build is a terminal-native AI coding agent and CLI tool from xAI (launched in early beta around May 2026). It brings Grok’s reasoning capabilities directly into your development workflow for professional software engineering and complex coding tasks.

Key Features
• Runs in your terminal — Install with one command (curl -fsSL
x.ai/cli/install.sh | bash). It supports a fullscreen TUI (text user interface) with mouse support, Plan Mode, parallel subagents, and more.

• Agentic workflows — Plan, code, test, debug, review changes, manage Git, deploy, and more from natural language prompts. It can handle end-to-end project building.
• Parallel subagents — Spawn multiple specialized agents (up to 8) working in isolated Git worktrees for faster, concurrent task handling.
• Powered by grok-build-0.1 — A specialized fast coding model (256K context window, optimized for tool use, agentic tasks, text image input). It’s distinct from the main Grok chat models but integrates with them.

• Skills, plugins & marketplace — Custom skills, plugins for tools like MongoDB, Vercel, Sentry, Cloudflare, etc., and headless/CI modes.
• Developer-friendly — Local-first (minimal code sent to servers in some modes), diff reviews, approval gates, real-time editing, and integration with your existing tools.
Availability
Available in early beta to SuperGrok and X Premium subscribers. There’s also API access via xAI’s models.
