Tesla Giga Texas: Vehicles, Optimus, Cortex and Terafab

Overview

Six Programs on One Campus

Vehicles, cells and cathode, Optimus, Cortex AI training and the Terafab Research Fab, all on one address.

Giga Texas sits on about 2,500 acres on the eastern edge of Austin in Travis County, along SH 130 above the Colorado River. Tesla broke ground in 2020 and opened the factory in April 2022. It has since built more than 500,000 vehicles and more than 100 million 4680 cells, employs more than 20,000 people, and is Austin Water's third-largest customer at 556 million gallons a year.

Giga Texas is one of the three manufacturing supernodes of the Austin Supercluster, with Samsung Taylor and the SpaceX Bastrop campus. No other US site combines vehicles, cells, humanoid robots, AI training compute and a semiconductor fab at one address.

Programs on the campus
Program	Status	What sets it apart
Vehicles	Model Y, Model Y L, Cybertruck and Cybercab; more than 500,000 vehicles built	The only US plant building the Model Y L; Cybercab fleet testing on the campus asphalt oval, with pilot production on AI4
Roadster (RFTX)	Roadster Factory Texas, being planned and built on the campus	A looping vertical track where Roadster owners can try the stunts the car performs on its own
Cells and cathode	4680 cell line past 100 million cells; cathode plant operating at scale since August 2026	North America's first large-scale cathode plant for 4680 cells, fed by lithium hydroxide from Robstown
Optimus Factory	Under construction; actuator and drive lines planned	Builds Optimus 4. Optimus V3 is built at Fremont
Cortex 1 and 2	Operating; Cortex 2 expanding	A dedicated Megapack and switchyard installation beside Cortex 2, moving toward about 250 grid-buffer units
Terafab Research Fab	Under construction on the east side of the campus	A joint Tesla-SpaceX fab: the research and pilot line for autonomy and space silicon, feeding volume production at Gibbons Creek

Each dot is a supplier. Distance from the center is how close it sits to the campus; the wedge is the program it serves; color is the parent company's home country; a solid dot is operating, a half-filled dot is under construction, a hollow dot is announced.

The ring maps 83 suppliers across five programs: vehicles, cells and robotaxi; Optimus; Cortex AI training; Terafab; and the campus power, water and construction base. 16 of the entries are Tesla itself, from the 4680 line and Cortex 2 to Brookshire and Robstown, because vertical integration puts much of the supply chain inside the company.

The vehicle program reaches farthest: LFP cells from CATL and BYD in China, die-casting presses from IDRA in Italy, robots from FANUC, Yaskawa, KUKA and ABB, and silicon carbide from STMicroelectronics in Catania. Terafab draws on the same Austin-metro equipment and materials base that serves Samsung Taylor.

Shared across anchors

Suppliers Shared With Other Texas Anchors

The same suppliers turn up around Samsung Taylor, Brookshire, Robstown and Starbase.

Select an anchor to light up the suppliers it shares with Giga Texas in the ring above.

Tesla's own Megapack plant at Brookshire shares the most with Giga Texas, 22 companies: cell and materials suppliers (CATL, BYD, Panasonic, Albemarle, Asahi Kasei), robot and automation makers (ABB, FANUC, KUKA, Omron, Rockwell) and silicon carbide from onsemi and Wolfspeed. Samsung Taylor shares 19, most of them the wafer fab equipment and materials suppliers the Terafab Research Fab will use. Meta Temple shares the Cortex side: Arista, Coherent, Supermicro, Vertiv, SK Hynix and TSMC.

The industrial gas, power and construction companies (Air Liquide, Air Products, Linde, Quanta Services, Hitachi Energy, Schneider Electric and Caterpillar) recur across nearly every anchor ring.

Why one campus

Why the Programs Share One Address

Suppliers. Linde, Air Liquide and Air Products serve every program; the Quanta Services, DPR and Rogers-O'Brien construction base builds vehicle, Optimus, Cortex and Terafab space at the same time.

Workforce. Engineers move between programs as priorities shift: from the 4680 line to Optimus actuators, from FSD compute to Cortex training infrastructure.

Infrastructure. One Oncor substation carries load for every program, and the 30 MW rooftop solar array and on-site Megapack storage serve them all. A second program at the same site costs less to power and water than the first program at a new one.

Silicon. The AI5 and AI6 chips that run the vehicles, Optimus and Cortex come from Samsung Taylor and TSMC Arizona, and the Terafab Research Fab here is the pilot line for the silicon that comes after them.

The Texas footprint

Giga Texas and the Rest of the Tesla-SpaceX Footprint

Giga Texas and the rest of the Tesla-SpaceX Texas footprint
Site	Location	Role for Giga Texas
Tesla Lithium Refinery	Robstown, Nueces County	Battery-grade lithium hydroxide for the cathode and cell lines
Tesla Megapack Brookshire	Brookshire, Waller County	Megapack and Megablock for the grid and for Giga Texas
Samsung Taylor Fab	Taylor, Williamson County	Fab 1 is Tesla-only, for AI5 and AI6
Terafab Gibbons Creek	Grimes County	Volume production fed by the research fab here
SpaceX Bastrop Complex	Bastrop County	Advanced packaging and satellite manufacturing

Constraints

Water and Power

Water. Treated water use rose 68% from 2023 to 2025, to 556 million gallons a year. The campus straddles the Austin Water and Travis County service boundaries, and the Terafab Research Fab is expected to add 350 to 700 million gallons a year at typical fab water intensity. See Texas Water Supply and Stress.

Power. ERCOT serves the campus through Oncor at 138 kV and above. Rooftop solar and Megapack storage cover non-process loads and buffer Cortex 2; the Terafab Research Fab needs fab-grade power quality that on-site generation cannot fully supply.
