Researched with AI assistance, checked by scripts. These rows were researched by AI agents reading public operator, laboratory and vendor sources, appended by scripts and checked by automated validation; no subject-matter expert has reviewed them (how this site is made). A mechanical second-reader pass has since fetched every cited source: 1350 of 1581 systems have a readable citation that names them, and 64 are genuinely weakly sourced. Every claim carries its source and a confidence tier. Treat anything below verified as a lead, not a citation.

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
Larsen & Toubro's 13 August 2026 press release says Vyoma.AI, through its subsidiary LTN Compute, secured an order to deploy 10,000 NVIDIA B300 GPUs in a single cluster at Vyoma's Chennai data centre campus for the US AI cloud company Together AI, covering the data centre, accelerated computing, high-performance networking, parallel storage and operations for Together AI's training, fine-tuning and inference platform. L&T calls it India's largest single-cluster AI infrastructure. The same release says the campus is a gigawatt-scale site with a 250 MW first phase and 150 MVA of power readiness; those are campus figures, not this cluster's draw. The release gives no go-live date, no interconnect or storage vendor, and no order value in figures, so status is planned rather than under_construction. CRN Asia repeats the release, so the two sources are not independent. Together AI's earlier cluster is together-hypertec-gb200. E2E Networks' 1,024-GPU B200 cluster at a Chennai data centre is a separate row (e2e-chennai-b200); the fetched pages do not say whether it shares this campus.
