xAI just made its coding agent available where most of the world’s developers actually work. The company released a Windows PowerShell installer for Grok Build, its terminal-native AI coding tool, on May 25, 2026, bringing plan-and-approve workflows, parallel subagents, and headless scripting to the platform that still dominates enterprise desktops.

What Grok Build actually does

Grok Build is a command-line interface that embeds xAI’s Grok models directly into a developer’s terminal environment.

The tool ships with several capabilities designed for professional software engineering teams. It supports an interactive terminal user interface (TUI), meaning developers can have structured back-and-forth sessions with the AI without leaving their terminal. There’s also a headless mode triggered by a -p flag, which lets teams run the agent in automated pipelines without human interaction.

The parallel subagent feature allows Grok Build to spin up multiple AI agents simultaneously to work on different parts of a codebase.

Plan mode offers a structured workflow where the AI proposes changes, presents clean diffs showing exactly what it wants to modify, and waits for human approval before touching anything.

The tool also integrates with AGENTS.md documentation and existing repository configurations. xAI additionally introduced something called the ACP protocol for building custom bots on top of the platform.

The model under the hood

Grok Build runs on the Grok Build 0.1 model, which xAI made available through its API on May 20, 2026, five days before the CLI launch. The model supports a context window of up to 256,000 tokens.

API pricing sits at $1 per million input tokens and $2 per million output tokens.

Windows users can install the tool by running a single PowerShell command: irm https://x.ai/cli/install.ps1 | iex.

Who gets access, and who doesn’t

This is an early beta, and xAI is limiting access to SuperGrok and X Premium+ subscribers.
