TLDR
- Elon Musk announced a joint Tesla-xAI project called “Macrohard,” also referred to as “Digital Optimus”
- The system pairs xAI’s Grok model with a Tesla AI agent that reads live screen video and controls keyboard and mouse inputs
- xAI has reportedly paused the original standalone Macrohard project, with over 20 engineers leaving or moving to other teams
- The project will run on Tesla’s AI4 chip alongside xAI’s Nvidia-based server hardware
- Tesla agreed in January to invest $2 billion into xAI; SpaceX merged with xAI last month in an all-stock deal
Elon Musk on Wednesday announced a joint project between Tesla and his AI company xAI, calling it “Macrohard” — or alternatively “Digital Optimus.” He described it as a system capable of emulating the functions of entire software companies.
Macrohard or Digital Optimus is a joint xAI-Tesla project, coming as part of Tesla’s investment agreement with xAI.
Grok is the master conductor/navigator with deep understanding of the world to direct digital Optimus, which is processing and actioning the past 5 secs of…

The name is a deliberate nod to Microsoft. “That is why the program is called MACROHARD, a funny reference to Microsoft,” Musk wrote on X.
The system works by pairing xAI’s Grok large language model as a high-level “navigator” with a Tesla-built AI agent. That agent processes live computer screen video while also handling keyboard and mouse inputs in real time.
Unlike tools that analyze static screenshots, Digital Optimus is designed to operate on a continuous stream of data. The goal is for it to autonomously interact with software, write code, and make decisions on the fly.
Musk said the system will run on Tesla’s in-house AI4 chip combined with xAI’s Nvidia-based server hardware. He described the setup as cost-competitive.
The announcement follows a period of quiet around the original Macrohard project. According to Business Insider, xAI has effectively paused that standalone effort.
As of Wednesday morning, there were no open job listings for the Macrohard team on xAI’s website. More than 20 engineers previously working on the project have either left the company or shifted to other departments in recent months.
xAI filed a trademark application for the “Macrohard” name back in August 2025, records from the U.S. Patent and Trademark Office show.
Tesla’s Growing Ties With xAI
In January, Tesla announced plans to invest approximately $2 billion into xAI. Tesla CFO Vaibhav Taneja said the logic was straightforward: if xAI can help speed up Tesla’s technology development, closer collaboration makes sense.
Last month, SpaceX acquired xAI in an all-stock deal. That transaction valued SpaceX at $1 trillion and xAI at $250 billion. Musk cited orbital data centers as a key reason for the merger, which came ahead of a potential SpaceX IPO later this year.
Wall Street View on TSLA
Analysts currently hold a Hold consensus on Tesla stock, based on 13 Buy ratings, 11 Holds, and 7 Sells over the past three months.
The average price target from Wall Street sits at $399.25 per share, suggesting the stock is trading near what analysts consider fair value.
Tesla was down 1.68% on Wednesday. The Macrohard trademark application was originally filed in August 2025, months before Wednesday’s joint announcement between Tesla and xAI.
