Elon Musk unveiled a joint Tesla and xAI project called "Macrohard" or "Digital Optimus," an AI system designed to emulate the functions of entire software companies. The system pairs xAI's Grok language model with a Tesla AI agent that processes real-time computer interactions like screen video and keystrokes.
The announcement follows significant corporate moves, including a Tesla investment in xAI and a SpaceX acquisition of xAI, partly motivated by plans for orbital data centers. Musk stated the system will run on a cost-competitive combination of Tesla's AI4 chip and xAI's server hardware.
The launch responds to a competitive landscape where AI agents like Anthropic's Claude Cowork are raising investor concerns about disruption to established software business models.
Main Topics: Announcement of the "Macrohard" AI project, its technical composition, the corporate and financial context behind it, and the competitive landscape of agentic AI.
- Elon Musk on Wednesday unveiled a joint project between Tesla and his artificial intelligence startup xAI, which he called "Macrohard" or "Digital Optimus" and said that it was a system capable of emulating the functions of software companies.
In a post on his social media platform X, Musk âsaid the â project â pairs xAI's Grok large language model, acting as a high-level "navigator," with a Tesla-developed AI agent that processes real-time computer screen video and keyboard and mouse actions.
The launch of Anthropic's Claude Cowork, which can perform a range of computer-based tasks autonomously, has already spooked software investors who fear that agentic AI can disrupt â established business âmodels.
Musk's xAI was previously building Macrohard as an AI project that would allow developers to simulate software â creations by companies like Microsoft.
"In principle, it is capable of emulating the function of entire companies. That is why the program is called MACROHARD, a funny reference to Microsoft," Musk said on Wednesday.
Musk said the system would run on Tesla's in-house AI4 chip paired with xAI's Nvidia-based server hardware, describing the combination as cost-competitive.
The announcement âcomes after Tesla entered into an agreement in January to invest about $2 billion to acquire shares in xAI.
SpaceX acquired xAI last month â in an all-stock deal that valued the rocket maker at $1 trillion and xAI at $250 billion, coming ahead of a potential blockbuster initial public offering for SpaceX later this year, with Musk citing orbital data centers as a main reason for the merger.
Records from the U.S. Patent and Trademark Office show that xAI filed a trademark application for "Macrohard" in August 2025.
