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.
Power comparison
1.7 MW is at the 45th percentile among the 310 operating AI Training records with a reported power figure. These represent 84% of the 369 operating AI Training records tracked; announced, under-construction and campus build-out figures are not ranked. The scale ends at the largest operating figure in this group, 1,276 MW.
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.
