What happened

xAI open-sourced Grok Build on July 15, 2026 — its coding agent and terminal UI (TUI) for professional developers is now available at github.com/xai-org/grok-build.

Context and impact

The open-sourcing came one day after a security incident: researchers discovered that Grok Build was uploading large portions of users' code repositories to Google Cloud without clear disclosure. xAI responded by promising to delete the uploaded data and open-sourcing the tool as a transparency measure. Developers can now audit exactly what the client sends.
