# Cortex supercomputer

ERCOT data center · https://askthegrid.com/assets/facilities/cortex-supercomputer

Tesla operates Cortex 1, an AI-training-compute data center at Gigafactory Texas in Austin, with more than 100,000 H100-equivalent GPUs installed and an initial 50,000-GPU cluster that went live in Q4 2024. The facility requires 130 MW of data-center power and includes 260 MWh of behind-the-meter battery storage plus a 250 MWh front-of-the-meter ERCOT-participating Megapack system. Tesla also operates 15 MW of rooftop solar generation at the broader Giga Texas facility.

## Power and grid context

- Critical it load: 130 MW · reported · exact asset · Cortex 1 · as of 2025-05-15 — Reported data-center power/cooling requirement associated with Cortex 1 at Giga Texas; kept separate from campus gross power and Cortex 2.0.
- Battery storage: 130 MW · reported · building · Cortex 1 · as of 2025-05-15 — Behind-the-meter Megapack system reported for the Giga Texas data center, with 260 MWh of storage; the source identifies it as a backup-power installation.
- Battery storage: 125 MW · reported · building · Cortex 1 · as of 2025-05-15 — Front-of-the-meter ERCOT-participating Megapack system reported at the Tesla Giga Texas facility, with 250 MWh; it is described as capable of backup power during a grid outage.
- Onsite generation: 15 MW · reported · campus · as of 2025-05-15 — Rooftop solar capacity reported for the overall Giga Texas facility; the source does not allocate this generation specifically to Cortex.
- ISO/RTO: ERCOT
- Balancing authority: ERCOT

## Development

- Site status: Operating; Tesla's Cortex 1 is listed as in production. The broader Gigafactory Texas campus is reported by Tesla as covering 2,500 acres, but that acreage is not attributed to Cortex 1 specifically.
- Construction: Tesla's Cortex 1 is a dedicated data-center building at Gigafactory Texas. Tesla completed deployment of a 50,000-Nvidia-H100 training cluster during Q4 2024, and Tesla's later reporting lists Cortex 1 as in production with more than 100,000 H100-equivalent capacity. Cortex 2 is a separate subsequent construction phase and is excluded from this record.

## Compute and operations

- Facility classes: ai_hpc
- Workloads: Full Self-Driving (FSD) and autonomous-driving neural-network training, Autonomous-vehicle and fleet-data processing, Optimus humanoid-robot hardware and software training, Real-world AI, perception, planning, and control model development
- Operating context: Tesla-owned, internally operated AI/HPC training cluster at Gigafactory Texas in Austin. The initial Cortex cluster came online in Q4 2024 with 50,000 Nvidia H100 GPUs; Tesla expanded Cortex in 2025. Cortex 2 is a separate subsequent project and is excluded from this record. It is not presented as a retail colocation or third-party cloud facility.

## Data quality

- Cortex 1 is treated separately from Cortex 2.0; reporting about Cortex 2.0 was excluded from exact-asset findings.
- The strongest exact-asset evidence identifies Cortex as Tesla’s training cluster at Gigafactory Texas in Austin, but generally does not provide a street address or parcel for the dedicated building. Parent-campus hearings, incentives, environmental concerns, and community investments are labeled as campus-level rather than Cortex-specific. No unsupported MW, water-use, PUE, WUE, building-count, tenant, or commercial-term claims are included.
- Removed uncited provider news result: Tesla’s 50,000 GPU Cortex supercomputer went live in Q4 2024
- Power values retain their reported, requested, contracted, energized, gross-campus, or critical-IT basis.
