xAI opens Grok Build code and resets usage limits for every user

Grok Build moves into the open

xAI used a July 15 X post to turn Grok Build from a product surface into an inspectable developer artifact. The company said it had open-sourced Grok Build, reset usage limits for all users, and pointed developers to the Git repository for the Grok Build CLI.

"open-sourced Grok Build" — xAI

The linked x.ai page describes Grok Build as xAI’s coding agent and CLI. It includes a GitHub link and command examples for building, validating, linting, and formatting the project. Those details matter because coding agents are not judged only by the frontier model behind them. The harness, permission model, command execution path, context handling, and local developer workflow can determine whether the tool is reliable enough for real repositories.

This post drew unusually high attention for a tooling update, with more than 13,000 likes and over 5.4 million views in the FxTwitter record. A follow-up post addressed privacy, saying Grok Build has respected zero data retention since launch and that users can disable data upload in the CLI. What to watch next is the repository’s actual pace: accepted pull requests, vulnerability reports, documentation quality, and whether enterprise controls appear quickly.
