Today in Compute College

Lesson & Term of the Day

Today's lesson

What are Prometheus and Hyperion? Meta AI campuses explained

The latest build status for Meta’s Ohio and Louisiana AI campuses, and what remains future capacity. Why it matters today: Today’s lesson gives readers one first-party Compute College concept to connect with the market signals in this brief.

Term of the Day

Closed model

A closed model is controlled by a provider and usually accessed through an API or hosted product rather than downloaded and run independently. The provider manages the infrastructure, optimization, and safety controls. Customers pay for usage without directly seeing the full compute stack.
