Executive Order on the Safe, Secure, and Trustworthy Development and Use of Artificial Intelligence | The White House

Basically - "any model trained with ~28M H100 hours, which is around $50M USD or - any cluster with 10^20 FLOPs, which is around 50,000 H100s, which only two companies currently have " - hat-tip to nearcyan on Twitter for this calculation.

Specific language below.

"   (i)   any model that was trained using a quantity of computing power greater than 1026 integer or floating-point operations, or using primarily biological sequence data and using a quantity of computing power greater than 1023 integer or floating-point operations; and

(ii)  any computing cluster that has a set of machines physically co-located in a single datacenter, transitively connected by data center networking of over 100 Gbit/s, and having a theoretical maximum computing capacity of 1020 integer or floating-point operations per second for training AI."
