Elon Musk has pushed back against reports that xAI shelved its “Macrohard” artificial intelligence project, saying the effort is still active and has been folded into Tesla’s “Digital Optimus” initiative. In his account, the two are now essentially the same project and are being developed jointly by xAI and Tesla.
Macrohard and Digital Optimus now framed as one effort
Business Insider had reported that xAI paused Macrohard, a project designed to simulate how software companies operate, and shifted its focus toward building a digital humanoid system for Tesla under the Digital Optimus name. Musk responded on X, rejecting that claim. He said Macrohard and Digital Optimus were combined after Tesla’s recent capital injection into xAI, turning them into a shared program.
Musk said the goal is not limited to analyzing screenshots. He described a system built to process continuous streams of information and react in real time, handling autonomous software interaction, code generation, and immediate decision-making. In that setup, xAI’s Grok serves as the higher-level reasoning layer, while Digital Optimus AI handles the fast-response layer by processing the past five seconds of screen activity along with keyboard and mouse inputs.
Real-time AI ambition tied to Tesla hardware economics
Musk also highlighted the hardware angle. He said the system would run competitively on Tesla’s AI4 chip, which he priced at $650, while requiring only a limited amount of more expensive Nvidia hardware from xAI. He called it the “only truly real-time intelligent AI system” and described the project as a major development.
He also repeated the idea he first outlined in August 2025: because software companies such as Microsoft do not manufacture physical hardware themselves, it should in principle be possible to fully simulate their operations with AI. That thinking is what led to the name “Macrohard,” a reverse play on Microsoft. Musk said no other company can currently do this.
Hiring freeze and staff moves fed shutdown speculation
The outside doubts did not emerge without context. As of Wednesday morning, the number of open roles listed for the Macrohard division on xAI’s website stood at zero. Over the past few months, more than 20 engineers involved in the project had either left or been reassigned to other teams. Those shifts appear to have contributed to the report that the project was paused, while also pointing to a broader internal reshuffle.
At the same time, coordination across Musk-led companies has been accelerating. The source material says xAI recently merged with SpaceX, and Tesla announced in late January that it planned to invest as much as $2 billion in xAI. Tesla CFO Vaibhav Taneja defended the move, saying that if xAI can help accelerate Tesla’s progress, there is a clear reason to make the investment and that the decision is part of a broader strategic plan.
