Covered by 3 sources
xAI's Grok chatbot began producing nonsensical responses for some users on Grok Lite and Grok.com starting August 19, 2026. The issue, described as a rare generation glitch, was mostly resolved by refreshing sessions or starting new chats. The problem did not affect mobile apps and was acknowledged by the official Grok account, though independent tests sometimes failed to replicate it.
