xAI faces backlash over uploading user Git repos

xAI's Grok Build coding tool uploaded entire Git repositories, including full commit history, to xAI's cloud storage without clearly informing users.

Security researcher Hari reversed the Grok Build binary and reported that a controlled session with zero tool-calls uploaded the complete codebase.

Enterprise customers using xAI's Zero Data Retention (ZDR) do not have their code or trace data stored.

During testing of Grok Build version 0.2.93, a researcher intercepted an upload that included a file the AI was instructed not to read.

In a test with a 12 GB repository, Grok Build uploaded 5.10 GiB of data—27,800 times more than the 192 KB the model actually used for the task.
