Elon Musk announces Terafab's establishment in Texas: integrating SpaceX, Tesla, and XAI to accelerate chip fabrication processes

Elon Musk announced on X that Terafab is officially launching in Texas. The project will be developed jointly by Musk’s three companies: Tesla, SpaceX, and AI company xAI. The goal is to build high-performance AI chip infrastructure, significantly improving energy efficiency and chip manufacturing iteration speed, breaking through current technological bottlenecks, and pushing human civilization toward a higher level of energy computation scale. This article is summarized from the video “Elon Musk Unveils Insane New Project – SpaceX, Tesla & Starship.”

Musk aims to realize the sci-fi scenario of the Kardashev Scale and make humanity a multi-planet species.

Using the Kardashev Scale, Musk explains that current human civilization is transitioning from Type I to Type II. Data shows that the Sun accounts for 99.8% of the total mass in the solar system, while Earth receives only about one five-hundred-millionth of the Sun’s total output. Currently, global electricity generation is only a trillionth of the Sun’s energy. Even if humanity increases energy production by a million times, we would only utilize one millionth of the Sun’s energy. This analysis highlights the limitations of Earth’s energy resources. To become a multi-planet species, we must break through existing energy acquisition methods and move toward large-scale solar energy development.

Why build the chip factory in Texas?

Musk states that choosing Texas for the factory can change the recursive cycle of semiconductor design. The new facility will integrate logic chip manufacturing, memory production, photolithography masks, chip testing, and subsequent modifications within the same building. This configuration eliminates delays caused by cross-facility logistics, allowing design teams to immediately improve based on testing results. Musk believes this rapid iteration capability enables continuous physical limits testing and unconventional architecture design. Compared to traditional decentralized supply chains, this centralized production process offers significant advantages in design optimization speed.

Terafab aims to produce 1 terawatt of computing power annually, equipped with Optimus robots, Tesla, and SpaceX.

Terafab’s goal is to generate 1 terawatt of computing power per year. In terms of application scenarios, the project plans to optimize dedicated chips for different needs. One type focuses on edge inference, mainly used in Optimus robots and Tesla; another targets high-performance computing (HPC) for SpaceX satellite systems. This differentiation allows the system to maintain optimal performance in various environments. This move reflects that computing resources have become a key infrastructure for technological advancement, with increased capacity directly impacting automation and space exploration progress.

Musk envisions deploying electromagnetic mass drivers on the Moon to send computing power into outer space, supporting economies beyond Earth. He predicts that when energy and computing costs drop significantly, it will create a highly resource-rich environment, making deep space exploration to Saturn and beyond possible. This vision is not only technological expansion but also an economic shift from Earth-centric activities to multi-planet development. Under this framework, Earth is seen as a tiny presence in the universe, and human progress depends on spreading computing power and energy throughout the solar system.
