Elon Musk throttles Grok Bot limits due to ‘unsustainably high’ costs

Over Halloween weekend some Grok Bot users found their weekly usage limits unexpectedly maxed out, and Elon Musk confirmed on X that it was not a glitch, writing that "the cost of serving Grok Bot was unsustainably high relative to revenue." Grok Bot has been positioned as a success for the newly public SpaceX, which said in a filing last month that AI now makes up 52% of company income, with its renamed "Super Intelligence" division posting a $431 million profit. Musk has not yet shared how subscribers' usage limits will be affected moving forward.
