xAI Launches "Grok Build" — a Terminal-Born Coding Agent, Now in Early Beta for SuperGrok
xAI released an early beta of “Grok Build,” a coding agent designed to be used directly from the terminal. It’s available to all SuperGrok and X Premium Plus subscribers, positioned to automate complex professional software development tasks. The launch comes more than a year after Anthropic’s “Claude Code” and OpenAI’s “Codex” entered the same space.
Details
- How it’s delivered: A CLI tool launched with a single command inside a project folder. Users describe tasks in natural language, and it analyzes the codebase and gets to work
- Plan mode: For complex tasks, it presents a plan before execution, which users can approve, comment on step by step, or have rewritten entirely
- Parallel subagents: Large tasks are split across specialized subagents that run in parallel, with support for integrating work across multiple worktrees
- Compatibility with existing tools: Supports AGENTS.md, plugins, hooks, skills, and MCP servers
- Headless execution: The
-pflag allows it to be embedded into scripts and automation pipelines - ACP support: Also provides a foundation for building custom bot orchestration apps
An earlier limited beta
- According to some reports, xAI had already offered an earlier, more limited beta around May 14, available only to subscribers of the top-tier $300/month “SuperGrok Heavy” plan
- The May 25 announcement marks the point at which access was expanded to all SuperGrok and X Premium Plus subscribers
- During the beta period, users are encouraged to submit feedback via the
/feedbackcommand within the CLI
What happened next
- On May 29, “grok-build-0.1,” the foundation model powering the CLI, became publicly available in beta via the xAI API
- On June 11, a plugin marketplace was added, enabling integrations with major services such as MongoDB and Vercel
- On June 15, an “Agent Dashboard” was added for managing multiple sessions at once
- On July 15, in response to a recently uncovered issue involving unauthorized repository uploads, the entire source code was released under the Apache 2.0 license
