Grok bot just hit a roadblock. SpacexAI caps Grok Bot usage as Elon Musk confirms operating costs of the AI agent has become unsustainable. Musk said that Grok Bot’s weekly allowances have been reduced because the cost of running the agent had become too high relative to revenue. The move follows rapid growth, with Grok Bot reportedly reaching 800,000 paid weekly users within two months. Users have complained that their allowances are now running out much faster, with some reporting usage limits being reached days before the weekly reset. Musk says the changes are necessary to keep the service sustainable, while hinting that higher-usage plans may offer more capacity.
