Tesla Cortex 2
Operated by Tesla at Tesla Gigafactory Texas .
Phase 1 seed dataset, compiled by hand. These rows were built from public operator, laboratory and vendor sources. A mechanical second-reader pass has since fetched every cited source: 1092 of 1153 systems have a readable citation that names them, and 40 are genuinely weakly sourced. Every claim carries its source and a confidence tier. Treat anything below verified as a lead, not a citation.

Figures are as last publicly reported for the configuration described below, not a live measurement. Where a system was upgraded in place, the post-upgrade configuration is shown and the earlier one appears in the timeline.
What this machine is made of
One row per supplier relationship. “Supplier at build” is the company that shipped the part at the time; where that company has since been acquired, the parent it rolls up to today is shown beside it. That distinction is what makes ticker-level aggregation possible across a thirty-year dataset.
| Role | Part | Supplier at build | Quantity | Confidence | Source |

The read
The second Tesla AI training cluster at Gigafactory Texas. Tesla's Q1 2026 shareholder deck says Cortex 2 is now online and running training workloads and lists it as Early Ramp with an installed annual capacity of more than 130,000 H100-equivalent GPUs, beside Cortex 1 at more than 100,000 H100-equivalents in production. That is Tesla's own normalised unit: the deck does not say which GPUs are installed or how many physical devices that is, and it counts early-ramp capacity as expected rather than installed, so no accelerator quantity or part is recorded. The first-operational month is the month of the deck that first shows it running, not a stated go-live date. The second source is a trade report of the same deck, so the row stays reported. No power, FLOPS or interconnect vendor is disclosed.

Source check
We fetched this system's own citations and recorded whether each page actually mentions it. This is a corroboration signal, not a fact check, and it is published so you can see how well the sourcing holds up rather than take it on trust.
