**[Grok Build](https://x.ai/cli)** is xAI's official CLI coding agent, **released as early beta on May 14, 2026** ([official](https://x.ai/cli) / [Changelog](https://x.ai/build/changelog) / [npaka's Japanese note write-up](https://note.com/npaka/n/nd813d073196e)). Alongside Claude Code, Codex CLI, Gemini CLI, and [agmsg](../columns/agmsg-cross-agent-messaging-cli-ai-2026-06), Grok Build is **xAI's entry in the CLI coding-agent space**. Its key differentiators are **up to 8 parallel sub-agents isolated in separate Git worktrees**, a Plan-Review-Approve workflow, **ACP (Agent Client Protocol) + MCP servers**, and **local execution** (air-gap-compatible). **Model & pricing**: - Internal model: **grok-build-0.1** (256K context, API rates **$1.00/M input, $2.00/M output**); **Composer 2.5** for SuperGrok / X Premium+ - SWE-Bench Verified **70.8%** (vendor-reported; ~17 pts behind Claude Opus 4.7 87.6% and GPT-5.5 88.7%) - Access gated to **SuperGrok Heavy ($300/mo; $99/mo introductory promo)**, SuperGrok, and X Premium+ **Install**: `curl -fsSL https://x.ai/cli/install.sh | bash`. **Integrations**: AGENTS.md / plugins / hooks / Skills / **Plugin Marketplace (MongoDB / Vercel / Sentry / Chrome DevTools / Cloudflare / Superpowers)** / Agent Dashboard / `/goal` long-running autonomous mode / headless `-P` flag for CI/CD. **Strategic context**: the February 2026 **SpaceX × xAI merger**, SpaceX's disclosed **$60B acquisition option on Cursor**, and Composer 2.5 currently training on **Colossus**, xAI's in-house supercomputer — Grok Build sits inside an unusually vertically-integrated stack. **Caveats**: roughly **15× the price** of Claude Code / Codex CLI bundles ($20/mo); ~17 pts behind on SWE-Bench Verified; no IDE integration (terminal only); flagship demos such as Arena Mode remain unshipped. Where it wins: **Git-worktree parallelism, xAI ecosystem integration, and local execution**.
