xAI's Grok chatbot has been sending gibberish responses to some users, with one user receiving the reply: “match it without and your they and two for planets can practical and often cheese…” after asking the model to generate a PDF.
Affected users who spoke to TechCrunch said they were using Grok Lite and noticed the issues as early as Wednesday morning. TechCrunch was unable to reproduce the issue in its own testing, and it is likely affecting only a small subset of users.
The bug appears to be limited to direct queries on Grok.com, and the Grok account on X.com has been unaffected. Refreshing the session often restores normal function, but some users reported the gibberish continued even after multiple refreshes.
Responding to unhappy users, the Grok account confirmed the issues on X, writing: “That pure word salad is a rare temporary generation glitch. Official status at https://status.x.ai shows all Grok services fully operational with no incidents. Start a fresh chat or regenerate—it usually clears right away. Sorry about the gibberish.”
