[Grok Bot Suspected of Sudden Tightening of Usage Limits; Musk Responds: Service Costs Too High to Sustain] Beating AI News reports that xAI's AI Agent product, Grok Bot, has recently faced numerous user complaints. Some paid users have found their weekly usage limits being consumed very quickly. Some reported their usage jumping from 44% to 87% in just 24 minutes; others used only half their limit before bed but woke up at 100%, without running any tasks in between. Many users suspect that the platform suddenly reduced their limits by nearly half midway through the weekly reset cycle. Grok Bot continuously performs tasks for users via cloud computers, browsers, and external tools. It is included in some paid subscriptions, and usage limits are typically reset weekly. In response to user requests for limit resets, Musk stated, "The cost of providing the Grok Bot service is too high to sustain relative to revenue." [Original Link]
