Overview
- Tesla and SpaceX, with xAI involvement, will jointly operate the Austin facility to secure advanced AI chips beyond what suppliers like TSMC, Samsung and Micron can provide.
- Terafab is pitched as a single-site, vertically integrated plant handling design, mask making, fabrication, testing and packaging to speed rapid redesign loops.
- Musk outlined two chip families: edge/inference parts for Tesla vehicles and Optimus robots, and space-hardened D3 processors for orbital AI satellites.
- He said terrestrial output would target roughly 100–200 gigawatts of compute per year, with most capacity ultimately on solar-powered satellites to reach a terawatt; SpaceX has already sought FCC approval for up to one million data-center satellites.
- Reporting places the price tag near $20–$25 billion, but Musk offered no construction or production schedule as analysts highlight major capital needs, scarce equipment and technical risk, with Starship cited as key to deploying orbital infrastructure.
