SpaceXSI apparently cuts Grok Bot quotas weeks after Musk called it his fastest-growing product

SpaceXSI has reduced usage limits for its Grok Bot AI agent, citing operating costs that were unsustainably high compared to revenue. This shift occurs less than two weeks after Elon Musk publicly described the tool as his fastest-growing product. The decision reflects a broader industry trend, as competitors like OpenAI and Anthropic have also begun tightening flat-rate subscription plans to manage the rising expenses of running large language models.
