CoreWeave AI cluster for Inflection AI
Operated by CoreWeave at CoreWeave (undisclosed US site) .
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.

The read
A NVIDIA H100 cluster co-developed by Inflection AI and operated by CoreWeave, which set the June 2023 MLPerf Training v3.0 GPT-3 175B result in under 11 minutes. CoreWeave's own blog and NVIDIA's blog independently give the same cluster at 3,500-plus and 3,584 H100 GPUs respectively on NVIDIA Quantum-2 InfiniBand, so the tier is verified. Inflection AI separately announced a target of 22,000 H100 GPUs for its full buildout with CoreWeave, but no fetched source confirms that larger count was ever installed, so only the benchmarked 3,584 figure is recorded. No source states a physical location, so the site is undisclosed and USA reflects CoreWeave's home country only. It has never submitted an HPL result.

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.
