Musk unveils joint Tesla-xAI project ‘Macrohard,' eyes software disruption

Elon Musk has revealed a new joint project between Tesla and xAI called 'Macrohard' or 'Digital Optimus' aimed at creating a system capable of emulating the functions of software companies. The project pairs xAI's Grok with a Tesla-developed AI agent that processes real-time computer screen video and keyboard and mouse actions. The system will run on Tesla's in-house AI4 chip paired with xAI's Nvidia-based server hardware. xAI applied for a trademark for 'Macrohard' in August 2025.
