Known issue: Some users reporting brief auth hiccups on first install — fix below
xAI expanded access to Grok Build today — its terminal-based coding agent is now available to all SuperGrok and X Premium+ subscribers, not just the $300/month Heavy tier. If you have been waiting to try Grok Build without upgrading to Heavy, the wait is over. Here is how to install it, what is new in version 0.1.218, and what users are actually getting out of it.
What Is Grok Build?
Grok Build is xAI's terminal-based AI coding agent — positioned as xAI's answer to Claude Code, Codex, and Kimi Code CLI. It installs locally, runs from the command line, and can write code, manage files, call tools, coordinate sub-agents, and execute multi-step tasks autonomously. What distinguishes it from generic coding agents is its integration with the broader Grok ecosystem: it can call Grok's web search, X data access, and image generation tools as part of a unified workflow.
Until today, Grok Build was exclusive to SuperGrok Heavy subscribers at $300/month. The expansion to SuperGrok ($30/month) and X Premium+ ($40/month) makes it accessible to the vast majority of Grok's paid user base for the first time.
How to Install Grok Build
Installation is a single terminal command. Open your terminal and run:
npm install -g @xai/grok-build
After installation, authenticate with your SuperGrok or X Premium+ credentials:
grok-build auth login
Then start a session in any project directory:
cd your-project
grok-build
Auth hiccup fix: Several users reported an authentication error on first login after the expanded access rollout. If you see an 401 Unauthorized error, log out of the Grok app on all devices, clear the token cache with grok-build auth logout, wait 2–3 minutes, and re-authenticate. The issue is a token propagation delay on xAI's side during the rollout — not a problem with your account.
What's New in Version 0.1.218
The access expansion ships alongside version 0.1.218, which focuses on platform stability fixes:
- Linux image pasting fixed — a bug that prevented clipboard image paste in Linux terminal sessions is resolved. Image inputs now work reliably on Ubuntu 22.04+, Fedora 40+, and Arch-based distributions.
- Windows shortcut improvements — keyboard shortcuts for common actions (copy, paste, new session, abort task) have been remapped to standard Windows conventions. Previously some shortcuts conflicted with terminal emulator defaults on Windows 11.
- Crash prevention — a session stability fix prevents Grok Build from crashing during long-running tasks that involve more than 50 consecutive tool calls. Previously, memory pressure from extended agentic sessions caused intermittent crashes on lower-spec machines.
Recent Feature Additions Worth Knowing About
Version 0.1.218 is a stability release. The significant capability additions landed in the previous two weeks:
File Handling Skills
Grok Build can now read, write, move, rename, and organize files across directories as part of a task chain — not just the current working directory. This enables workflows like "reorganize this entire repo's folder structure" or "move all test files to a /tests directory and update the imports" without manual file management between agent steps.
Gmail Connector
Grok Build added a Gmail MCP connector — the same integration pattern Anthropic introduced with Claude's MCP ecosystem. The connector lets Grok Build read emails, draft replies, search threads, and send messages as steps within an agentic workflow. Example: "Find all emails about the Q2 project, summarize the open action items, and draft a status update to the thread." The connector requires Gmail OAuth authorization on first use.
Sub-Agents
Grok Build now supports launching sub-agents within a session — spawning parallel Grok instances to work on decomposed subtasks simultaneously. The sub-agent architecture mirrors Grok 4.20's native Expert Mode multi-agent system but operates at the CLI level, coordinated by the primary Grok Build session. This is the feature users are calling "turning Grok into a full AI operating layer" — a primary agent that orchestrates specialists rather than a single model doing everything sequentially.
Plugins
A plugin system lets developers extend Grok Build with custom tools — API connectors, data sources, and workflow shortcuts specific to their stack. The plugin registry is early-stage, but community-contributed plugins for GitHub, Linear, Notion, and Slack are already available. Installation: grok-build plugin install github.
Improved Image Generation
Grok Build now calls Grok Imagine 1.0 inline — you can request an image as part of a workflow step and have it saved directly to the project directory. Example: "Generate a hero image for this landing page and save it as /assets/hero.png." The image generation uses your SuperGrok Imagine quota.
What Users Are Reporting
Early reports from the SuperGrok community since today's access expansion:
- Several developers reported completing full feature implementations — writing code, tests, and documentation — in a single Grok Build session without leaving the terminal
- The plan review feature (Grok Build presents a step-by-step plan before executing) is the most-praised UX addition — users describe it as significantly reducing unwanted autonomous changes compared to other coding agents
- Gmail connector working on first use for most users; some reported needing to re-authorize after the 0.1.218 update
- Sub-agent spawning is fast — users report 3–5 second initialization per sub-agent on standard hardware
- Auth hiccup affected roughly 10–15% of users based on community reports — the logout/wait/re-login fix resolves it in all reported cases

Who Should Install Grok Build Today
If you are already a SuperGrok or X Premium+ subscriber and use the terminal regularly for development — install it now. The barrier is a single command and the capability set (sub-agents, Gmail, file handling, plugins, inline image generation) is immediately useful for real workflows. The plan review feature makes it safer to use autonomously than many alternatives.
If you are choosing between SuperGrok for Grok Build vs Claude Pro for Claude Code — Claude Code leads on published coding benchmarks and has more mature IDE integration. Grok Build's advantages are real-time X data, inline image generation, and the broader Grok ecosystem integration. Neither is universally better; the right choice depends on which ecosystem your daily tools already live in.
FAQ
How do I install Grok Build on SuperGrok?
Run npm install -g @xai/grok-build in your terminal, then grok-build auth login with your SuperGrok or X Premium+ credentials. If you get a 401 error, run grok-build auth logout, wait 2–3 minutes, and try again — a token propagation delay is affecting some users during today's rollout.
Is Grok Build free with SuperGrok?
Yes — Grok Build is included in the SuperGrok subscription at $30/month and X Premium+ at $40/month at no additional charge. Previously it required SuperGrok Heavy at $300/month. Usage within Grok Build draws from your SuperGrok plan's rate limits.
What is the difference between Grok Build and grok-cli?
grok-cli is the community-built open-source CLI that predates Grok Build. Grok Build is xAI's official first-party coding agent — maintained by xAI, with official plugin support, plan review, and the Gmail/file handling connectors. grok-cli remains available for users who want a more customizable or locally-hosted experience. For most users, Grok Build is now the recommended starting point.
Does Grok Build work on Windows?
Yes — version 0.1.218 specifically improves Windows shortcut compatibility. It runs on Windows 10 and 11 via Windows Terminal, PowerShell, or WSL2. The Linux image paste fix in 0.1.218 does not affect Windows users.
How does Grok Build compare to Claude Code for coding tasks?
Claude Code (Claude Opus 4.7) leads on published SWE-Bench Pro benchmarks at 64.3% — xAI has not published equivalent benchmark scores for Grok Build on the same evaluation. Claude Code has more mature IDE integration (VS Code, JetBrains). Grok Build has native real-time X data access, inline image generation, and is included with SuperGrok at $30/month without additional API costs.
