Elon Musk, CEO of Tesla, has unveiled the "Terafab" project, a large-scale artificial intelligence (AI) semiconductor production initiative involving Tesla, SpaceX, and XAI. The primary objective of the Terafab project is to achieve an annual computing performance of 1 terawatt (TW). Musk noted that given the current US electricity production capacity of only 0.5 TW, a significant portion of these computing resources would need to be deployed in space.

Terafab is deemed crucial for the mass production of Robotaxis and Tesla's humanoid robot, Optimus, as well as for the deployment of space-based computing equipment. The project is set to produce two main types of chips. One chip type is specifically designed for Optimus and Tesla's autonomous vehicles. Musk anticipates that the production volume for these Optimus chips will be 10 to 100 times higher than that of general automobile production. The second chip type, named 'D3', is specifically engineered for space environments. This is in anticipation that most future data centers will reside in low Earth orbit (LEO), necessitating the use of solar-powered AI satellites.

Musk also introduced a concept design for a compact AI satellite, equipped with solar power generation, capable of processing 100 kilowatts (kW) of power. He predicts that future satellites will reach megawatt (MW) class power capabilities. Furthermore, Musk envisions a future where his companies could establish industrial bases on the Moon, enabling petawatt (PW) scale AI computing capabilities, which would be 1,000 times more powerful than 1 TW. This vision extends to a future of abundance, including free travel to Saturn, made possible by such advanced computing infrastructure.
