Terafab is a chip manufacturing effort from Tesla, SpaceX and xAI aimed at closing the gap between today's chip production and future demand for AI compute. It plans to combine logic, memory and advanced packaging under one roof in a facility of roughly 100,000,000 square feet, targeting output of 1 TW per year. Planned chips include AI5 for FSD and Tesla Optimus, AI6 for Optimus, and D3 for use in space. The project frames orbital compute as a way to avoid Earth-bound costs such as land, permitting, energy and cooling, with lunar mass drivers as a later step.
