Elon Musk introduced Macrohard—branded Digital Optimus—for Tesla’s fourth-generation Hardware 4 EV computers, combining instinctive System 1 software agents with the Grok LLM as its thinking engine. The system runs on Tesla’s $650 AI4 chips at Supercharger stations, with “millions” of dedicated units deployed to autonomously process tasks such as email composition and virtual computing.

Tesla secured US regulatory clearance to convert its $2 billion xAI investment into a SpaceX equity stake exceeding the $133.9 million antitrust threshold, yielding under 1% ownership in the rocket company. The move reflects Musk’s strategy of interlinking his ventures ahead of a planned SpaceX IPO later this year.
