ai& Tenstorrent Galaxy Supercluster
Also known as ai& sovereign heterogeneous inference platform (Tenstorrent)
Operated by ai& .
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
Tenstorrent's 30 June 2026 TT-Deploy JP announcement says its largest deployment to date runs with ai&, with more than 120 Tenstorrent Galaxy systems that it calls the largest scale of sovereign AI compute in Japan, serving chat, RAG, vision and post-training workloads entirely from within the country. No site, per-system chip count or power figure is stated on the fetched pages, so the accelerator count records Galaxy systems, not chips, and is a floor. Both pages are Tenstorrent's own, so the tier is reported. The same page says Tenstorrent Japan also runs an AI data centre in Osaka, with no scale given.

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.
