> xAI’s Grok Build early beta brings a terminal-native coding agent to SuperGrok and X Premium+ — plan mode, parallel subagents/worktrees, AGENTS.md/MCP fit, headless automation. Coding agents are now table stakes for pro subscriptions, not only enterprise APIs; no independent Elo is published with the launch.

Terminal coding agents are now a competitive surface among frontier labs. Grok Build puts **xAI** alongside Claude Code, Codex, and peer CLIs — with a **subscriber-gated** beta rather than an open enterprise-only API story.

**xAI** (May 25) launched an early beta of **Grok Build**, a terminal-native coding agent and CLI for **SuperGrok** and **X Premium Plus** subscribers. Install: `curl -fsSL https://x.ai/cli/install.sh | bash`, then sign in with the subscriber account. Features emphasize plan-then-execute workflows, parallel subagents, and fit with existing agent conventions.

## What Grok Build ships

| Surface | Detail (xAI primary) |
|---------|----------------------|
| **Availability** | Early beta: SuperGrok + X Premium Plus |
| **Plan mode** | Propose plan; approve, comment, or rewrite before execution; changes as diffs |
| **Ecosystem** | AGENTS.md, plugins, hooks, skills, MCP servers out of the box |
| **Parallel subagents** | Specialized subagents; deep worktree isolation |
| **Automation** | Headless (`-p`); full ACP for custom bots/orchestration |
| **Feedback** | In-CLI `/feedback` |

The product continues xAI’s push into agentic developer tools after earlier May CLI previews, expanding access to the full SuperGrok and Premium+ base.

## Claims vs checks

Feature list and access gates are **xAI primary**. No Artificial Analysis / Arena coding-agent Elo ships with this announcement — do not invent one. Competitive “alongside Claude Code / Codex” is desk framing of the product category, not a published head-to-head.

## Limits

- Early beta — stability and capability ceilings unset.
- No independent coding-agent leaderboard snapshot at launch.
- Subscriber-only access; free-tier path not described.
