Some Grok users are receiving strings of unrelated words instead of normal chatbot answers, with xAI describing the problem as a temporary generation glitch affecting a subset of conversations.
Reports began appearing Wednesday from people using Grok Lite on Grok.com. In one case, a request to create a PDF produced several paragraphs of disconnected words, while another user found that the response included source links pointing to reinforcement learning research pages.
Grok users report repeated gibberish responses.
Complaints have spread through the Grok-subreddits community, where multiple users have described similar behaviour. Some said refreshing the session restored normal responses, while others reported the problem persisted after several attempts.
The apparent bug has primarily been reported with direct queries on Grok.com. The Grok account on X has not exhibited the same behaviour.
xAI calls it a temporary generation glitch
Responding to users on X, the official Grok account acknowledged the problem and described the nonsensical output as a rare temporary generation glitch. It advised affected users to start a new chat or regenerate the response, saying that typically resolves the issue.
The company’s status page showed services as operational, with no incident, when the response was posted.
The exact technical cause of the faulty responses has not been disclosed. Reports from users indicate the problem does not affect every account, and refreshing does not consistently resolve it for everyone.
xAI has also faced recent staff departures
The glitch comes during a period of significant personnel turnover at xAI, although there is no evidence connecting the departures to the current problem. The Information reported in May that more than 50 researchers and engineers had recently left the organisation, alongside departures from much of its founding team.
xAI released its latest foundation model in July, promoting improvements in speed, token efficiency and cost. For users encountering the current Grok.com issue, the company’s immediate guidance is to regenerate the response or start a new conversation.
