SpaceXSI is apparently cutting usage limits for its AI agent Grok Bot, less than two weeks after Musk called it his fastest-growing product. The operating costs were "unsustainably high relative to revenue," Musk wrote on X. OpenAI and Anthropic are also tightening their flat-rate plans as they grapple with the high costs of AI agents.
