Grok: High Demand / Capacity Limit

Grok shows this message when xAI's inference infrastructure is under peak load. Notably, this error affects X Premium subscribers as well as free users — it is not purely a free-tier restriction. xAI acknowledged a 29.5+ hour period in April 2026 where Grok remained in constant high-demand mode for premium users. After showing this error, Grok often appends an upgrade prompt for SuperGrok, which some users interpret as artificial pressure rather than genuine capacity rationing.
