Brief

Cortex 2 at Tesla’s Giga Texas is receiving about 260 Megapacks now, which will join roughly 140 already installed for an expected ~400 Megapacks across the site; installations are said to support AI datacenter operations and phase‑2 cooling/tower systems. Tesla projects nearly 400 MW of AI compute at Giga Texas by end of 2026, and Cortex 2 is described as the home of Optimus’ 'brain' (reported 2026-08-05).

Why it matters

≈260 Tesla Megapacks are being installed at the Cortex 2 data center at Giga Texas (reported 2026-08-05 by @niccruzpatane citing Joe Tegtmeyer).

Key details

  • Those ~260 Megapacks add to ~140 already on site in two installation locations, for roughly ~400 Megapacks total at Giga Texas once fully installed.
  • Tesla projects nearly 400 MW of AI compute at Giga Texas by the end of 2026; the Megapacks are intended to support AI datacenter operations and phase‑2 cooling/towers at Cortex 2, the reported home of Optimus’ 'brain'.
Source evidence

~260 Megapacks will be installed for Tesla’s Cortex 2 Data Center at Giga Texas.

Tesla projects nearly 400 MW of AI compute at Giga Texas by the end of 2026. This is the home of Optimus’ 🧠.

Cortex 2 at Giga Texas is getting many more Megapacks installed today, both to support the AI Datacenter operations & for the phase 2 of the cooling system/towers which are nearing operational status.

Once fully installed, there will be ~260 Megapacks supporting this one facility! This is in addition to the other 140 already on site in two different installation locations, meaning the overall Giga Texas site should have ~400 in total, once fully installed!
