Elon Musk has introduced Macrohard, a joint Tesla-xAI project that he says is designed to handle the kind of work done by a software company through AI. He has also referred to the effort as Digital Optimus and said it is part of Tesla’s investment agreement with xAI.
Musk described Macrohard as a system that could, in principle, emulate the functions of entire companies rather than just one software tool. The announcement puts Macrohard at the center of growing interest in AI agents that can carry out digital tasks on their own.
How Macrohard is supposed to work
According to Musk’s description, the project has two main parts. Grok, the chatbot developed by xAI, would act as the “master conductor” or navigator, while a Tesla-built AI agent would carry out actions on a computer in real time.
The Tesla side of the system is meant to watch a computer screen and respond to keyboard and mouse activity in a way that resembles a human operator. Musk compared the setup to two layers of thinking, with Digital Optimus acting as the instinctive part and Grok serving as the reasoning layer.
Musk also said the project would run on Tesla’s in-house AI4 chip together with xAI’s Nvidia-based server hardware. He described that combination as a lower-cost approach than depending heavily on expensive data centers and called it the “only real-time smart AI system.”
A broader push by Tesla and xAI
Business Today reported that Musk unveiled the project on March 11, while India Today said the latest announcement framed Macrohard as a joint venture between Tesla and xAI. Both reports said Tesla had committed about $2 billion in January to acquire shares in xAI.
Business Today also said Ashok Elluswamy, Tesla’s vice president for AI software, posted that the company was actively hiring talent for the effort. That suggests the companies are building both the technical system and the team behind it at the same time.
The name Macrohard itself was presented as a joke aimed at Microsoft. India Today added that Musk had already used the term in August 2025 for a similar idea focused on creating a software company run through AI.
Signs of trouble inside xAI
Even as Musk publicly promoted Macrohard, Business Insider reported that the xAI project had stalled. The outlet said the slowdown followed leadership changes and a pause in a data project involving more than 600 contractors.
According to that report, workers on the data effort had been asked to record their work and leisure activities so the system could learn how to emulate human actions as a digital agent. A project lead later told workers that researchers had found flaws in the model and wanted to change both the model and the way data was being collected.
Business Insider also reported that some Macrohard work and part of the project’s computing capacity were being shifted to Tesla’s Autopilot team. It said Tesla had been advancing its own internal AI agent project, also known as Digital Optimus, with a focus on real-time control methods rather than mainly relying on static screenshots.
That report described the Tesla approach as more similar to how the company’s Full Self-Driving system processes a continuous stream of visual information. It also said xAI had no job openings listed for the Macrohard team at the time of the report.
Leadership exits add pressure
Business Insider separately reported that xAI cofounders Zihang Dai and Guodong Zhang had left the company. After their departures, the outlet said only two of the 11 engineers who started xAI with Musk in 2023 remained.
The same report said Zhang had been leading Grok Code and Grok Imagine, while Musk told the Abundance Conference that “Grok is currently behind in coding.” Musk later wrote on X that “xAI was not built right first time around, so is being rebuilt from the foundations up.”
Those developments matter because Macrohard has been described as one of xAI’s core projects. Together, the project’s ambitious goals, the reported pause in development work, and the steady turnover among senior staff show that Musk’s vision for an AI-run software operation is moving forward under visible strain.
