It is built on 10,000 NVIDIA A100, alongside NVIDIA V100. That amounts to about 3.2K H100e of AI compute. The cluster draws roughly 14.52 MW. Its hardware is estimated at $409M.
Epoch AI rates the certainty of this record as likely. Unclear how many of the GPUs are A100s vs V100s The State of AI report indicates that they have 10k A100s, but it's unclear if they're just estimating this or have an actual source Also, the earliest point in the waybackmaching that the State of AI report mentions this cluster is March 2023, which is where the date comes from
