Elon Musk’s artificial-intelligence venture xAI has filed for a US trademark on the name “Macrohard,” according to public registration records cited by industry trackers on 2 August. The application covers software for building multi-agent systems, suggesting xAI is preparing a platform that would let separate AI agents collaborate on complex tasks. People familiar with xAI’s plans say the prospective product would rely on Grok, the large-language model the company released last year, as its underlying engine. While xAI has not commented publicly on the filing, the move signals Musk’s intention to broaden the start-up’s offerings beyond Grok’s conversational capabilities and into enterprise tools that compete with products from Microsoft and other AI developers.
