x.AI plays catch-up with Grok Build, its first terminal-based coding agent

x.AI has launched Grok Build, a terminal-based coding agent now in early beta for SuperGrok Heavy subscribers.

The tool includes plan approval, code diffs, parallel sub-agents, headless scripting, and support for existing agent configs like AGENTS.md and MCP servers.

Users can send feedback through a /feedback command as x.AI refines the product.

The launch puts x.AI into a coding-agent market already led by Anthropic and OpenAI, though access is initially limited.
