Elon Musk cut weekly usage limits for Grok Bot over Halloween weekend, with some users reporting their usage jumped to 100% despite minimal activity. Musk confirmed the move was not a glitch in an X post on Sunday. "The cost of serving Grok Bot was unsustainably high relative to revenue," he wrote in response to a user question.
Grok Bot sits within SpaceX's "Super Intelligence" division, which Musk recently called the fastest-growing product he has ever seen. In a filing last month, SpaceX said AI now makes up 52% of company income. The Super Intelligence division turned a profit of $431 million, though that figure would have been higher without $1.2 billion in one-time costs tied to SpaceX's acquisition of Cursor.
Musk has not yet disclosed how subscriber usage limits will change going forward.
