Elon Musk said on March 11 that Tesla and xAI are building a joint AI agent project called “Macrohard” or “Digital Optimus,” aimed at automating software work by pairing Grok with a Tesla-built agent that can control a computer, according to Reuters and CNBC. The move pushes Tesla further into enterprise AI and intensifies competition in computer-using agents beyond chatbots.
Musk’s description, echoed by Electrek, says Grok acts as the high-level navigator while the Tesla agent ingests the last five seconds of real-time screen video plus keyboard and mouse actions to execute tasks. CNBC reported the system is intended to run on Tesla’s AI4 chip alongside xAI’s Nvidia-based server hardware, signaling a split between on-device inference and data-center scale compute.
Reuters noted Tesla agreed to invest about $2 billion in xAI in January 2026 and that xAI filed a “Macrohard” trademark in August 2025, underscoring deeper corporate ties behind the project. Musk also claimed the system could “emulate the function of entire companies,” a bold statement that remains unverified without a public demo or benchmarks.
The positioning echoes OpenAI’s Operator, a computer-using agent that navigates web pages by typing, clicking, and scrolling, and arrives as Gartner forecasts that 15% of day-to-day work decisions could be made autonomously by 2028 and 33% of enterprise apps will include agentic AI by then. Without a timeline or deployment scope, execution risk—and whether the system can meet reliability and safety expectations at scale—remains the key unknown.
