Users on Grok.com began getting responses like "match it without and your they and two for planets can practical and often cheese" from Wednesday 20 August, sometimes running for paragraphs, and one user got strings of links to reinforcement learning research sites instead of an answer. xAI said it is "a rare temporary generation glitch" and told people to start a fresh chat, though some reported it persisting through refreshes. The Grok account on X was unaffected and TechCrunch could not reproduce it, so scale appears small.
