Multiple users have reported that SpaceX has quietly reduced usage quotas for Grok Bot, with some users' allowances directly halved. Musk publicly responded that Grok Bot's operating costs far exceed its revenue and that the situation is unsustainable, confirming that the commercialization of AI agents is under pressure from high computing costs. Previously, Grok Bot had been billed as SpaceX's fastest-growing star product, with strong growth in paid users—but the surge in user scale and high-frequency calls drove up computing consumption. Some users now have to wait several days for their quotas to refresh after exhausting them, and Musk even asked users whether higher-tier subscriptions were too expensive. Currently, the entire AI industry is grappling with an imbalance between computing costs and the subscription model, and several vendors have recently tightened their affordable plans in quick succession. The computing cost for AI agents to complete complex tasks can be 4 to 15 times that of ordinary simple conversations. How to balance user experience with high computing costs has become a pressing challenge that all large-model vendors urgently need to address.
