x.AI launches Grok Build terminal coding agent

x.ai launched grok build, a command-line interface coding agent, directly competing with similar tools from anthropic and openai. the software offers standard agent features including a plan mode for approvals, pre-change diffs, parallel sub-agents for complex tasks, and a headless mode for automation. x.ai retains existing configurations like mcp servers and plugins while gathering user feedback via a dedicated command. access is currently restricted to supergrok heavy subscribers as the product remains in early beta.
