xAI Expands Grok Build Beta to All Premium X Users

xAI expanded the beta for Grok Build, a terminal-based agentic coding CLI, to all SuperGrok and X Premium+ subscribers. This update follows the initial Grok Build launch and introduces Imagine support for generating images and videos directly from the terminal.
Availability
Beta for SuperGrok and X Premium+
Core features
Plan Mode, Subagents, Imagine
Protocols
MCP, ACP
Execution modes
Interactive, Headless
Installation
curl-based CLI

The move signals a shift toward multi-agent orchestration within local environments. By integrating MCP, Grok Build competes with OpenAI's Codex app launch by allowing agents to interact with external tools like Sentry or Postgres. This reduces the friction between planning and execution.

You can now use Plan Mode to approve architectural changes before the agent writes code or spawn parallel subagents to research and test simultaneously. The tool is available via a one-command install for eligible subscribers and supports headless mode. Subscription portability also enables workflows where OpenCode now supports Grok.

Still wondering? A few quick answers below.

Grok Build is a terminal-based coding agent and command-line interface designed for complex software engineering tasks. It allows developers to interact with codebases, perform multi-file edits, and run tests directly from their local environment. The tool uses specialized subagents and a structured Plan Mode to handle high-complexity development work and workflow automation autonomously.

The Grok Build beta is available to all users with a SuperGrok or X Premium Plus subscription. While it was previously limited to a smaller group of early testers, this update expands access to the broader premium subscriber base. Users can install the tool on their local machines using a single command-line script provided by xAI.

Plan Mode is a structured workflow for architecting complex projects. When a user starts a task in this mode, Grok Build proposes a detailed approach and specific steps before writing any code. Every edit is blocked until the user approves the plan, provides comments on individual steps, or requests a complete rewrite of the proposed architecture.

Subagents are specialized AI agents that Grok Build can spawn to run in parallel. Each subagent operates with its own context window and can handle specific tasks like researching infrastructure, exploring codebases, or running tests simultaneously. This multi-agent orchestration allows the system to tackle large-scale engineering problems more efficiently than a single monolithic model.

Yes, Grok Build supports the Model Context Protocol, which acts as a universal connector for AI tools. This allows the agent to integrate with external services like Linear, Sentry, and Postgres out of the box. Users can also bundle skills, hooks, and plugins into marketplaces to share specific capabilities across their engineering teams.
