Companies are grouped by their role at the site, with recorded parents above them. No parent companies were found in the ownership data. Further ownership remains unresolved where labelled. Record source: Epoch AI GPU Clusters; authority tier 2. Each role is drawn only as the relationship its own source establishes, listed above; none implies exclusive control of the full site. Ticks count the export-control and government-link findings for each company.

Every partition is admitted from the record’s own evidence. Rates are the cited dense FP16 figure per accelerator; the sum applies the methodology’s utilization and interconnect assumptions and is a theoretical aggregate, not one job’s throughput. The catalogue figures above are the record’s scalar fields (the source’s transcription, or its recorded correction) and are a different basis.

Methods and sources

Ownership roles

Title identifies the legal owner of the site; operation identifies who runs it. AI-hardware ownership follows the catalog’s attribution of the machines inside, whose owner may lease the facility.

Each role requires its own attribution. An operator named in a source supplies evidence of operation only.

Parent companies

Ownership checks start with each company named at the site and follow recorded parent relationships. A company holding several roles is checked once. Its linked company page lists the relationships and their sources; further parents may remain undocumented.

Level 1 identifies a company at the site, level 2 its parent, and each further level another parent. Export-control designations and government investments are assigned to the company concerned.

Missing values

Unrecorded roles remain blank. Findings whose company position is unresolved stay in the list with that position labelled unknown.

Publication limits

Subscription corporate data helps identify parent relationships and sovereign investments. Publication is limited to relationship classes and supporting public sources; licensed records, identifiers and values are withheld.

Epoch AI estimates capacity using satellite imagery, permits and corporate disclosures. Its catalog is the source for this site record.
