Vultr Chicago Cluster is a large GPU cluster operated by Vultr, located in the United States, in the private sector. It came online around December 2024. At that moment it ranked number 49 among known clusters.
It is built on 3,000 AMD Instinct MI300X. That amounts to about 4K H100e of AI compute. The cluster draws roughly 4.59 MW. Its hardware is estimated at $82M.
Epoch AI rates the certainty of this record as likely. Not totally certain that the "thousands" of MI300X's are all in this data center, but I'm pretty sure. I'm also estimating "thousands" as 3k
