We either build the Terafab or we don\u2019t have the chips, and we need the chips, so we build the Terafab.\u201d<\/em><\/p>\n<p>The CEO has hinted heavily for several quarters that it would probably need to produce its own computing power to stay up to speed on the demand it is facing for its projects. It is now taking matters into its own hands.<\/p>\n<h4>Chip Types and Production Goals<\/h4>\n<p>The facility will manufacture two specialized chip families, according to the presentation:<\/p>\n<ul>\n<li>Edge-inference AI5 and AI6 processors optimized for Tesla&#8217;s Optimus humanoid robots and Full Self-Driving systems in vehicles and Robotaxis<\/li>\n<li>High-power D3 chips hardened for space environments<\/li>\n<\/ul>\n<p>Musk outlined annual output targets, which are between 100 and 200 gigawatts of terrestrial compute for robotics, supporting Musk\u2019s vision of producing 1-10 billion Optimus units per year, and the majority (80%) of chips dedicated to orbital AI data centers. Overall, TERAFAB aims to produce 100-200 billion custom AI and memory chips each year.<\/p>\n<h4>Scale and Strategy<\/h4>\n<p>The <a href=\"https:\/\/www.teslarati.com\/elon-musk-lanuches-terafab-tesla-spacexai-chip-factory\/\">size of the TERAFAB project will be remarkable<\/a>, as Musk indicated after the presentation that the entire Gigafactory Texas campus would not be large enough to fit the needs of the project. In fact, Musk said it would be around 100 million square feet in size, the equivalent of 15 Pentagons or three Central Parks.<\/p>\n<p>Yes, the one in New York City.<\/p>\n<p>Construction will begin with an \u201cadvanced technology fab\u201d on the Giga Texas campus in Austin, enabling rapid iteration: design a chip, fabricate lithography masks, produce and test wafers, all within days.<\/p>\n<p>However, the full-scale TERAFAB requires thousands of acres and over 10 gigawatts of power, far exceeding what Giga Texas can accommodate. Musk stated:<\/p>\n<p style=\"padding-left: 40px;\"><em>\u201cWe couldn\u2019t possibly fit the Terafab on the GigaTexas campus. It will be far bigger than everything else combined there.\u201d<\/em><\/p>\n<p>Multiple large sites are currently under consideration, but this will need a sprawling land mass to get started.<\/p>\n<blockquote class=\"twitter-tweet\">\n<p dir=\"ltr\" lang=\"en\">The sheer scale of TERAFAB is going to be insane.<\/p>\n<p>Elon said it wouldn\u2019t be suitable for anywhere on Giga Texas property because it\u2019s too big:<\/p>\n<p>\u201cWe couldn\u2019t possibly fit the Terafab on the GigaTexas campus.

For that reason, we will break this down into Terrestrial and Orbital applications:<\/p>\n<ul>\n<li>Terrestrial: Powers autonomous vehicle fleets and billions of Optimus robots performing physical labor<\/li>\n<li>Orbital: Starship will launch massive AI satellite constellations, starting with 100-kilowatt &#8220;Mini&#8221; units, and scaling to larger Megawatt models, creating the world&#8217;s largest data center in low-Earth orbit.<\/li>\n<\/ul>\n<p>Space-based advantages include five times greater solar irradiance, efficient vacuum heat rejection, <a href=\"https:\/\/www.teslarati.com\/fcc-accepts-spacex-1m-orbital-data-center-filing\/\">and freedom from terrestrial grid constraints<\/a> (U.S. electricity generation totals just 0.5 terawatts).
