Today's lesson
GPU-hour
A GPU-hour is one graphics processor running for one hour. Why it matters today: GPU-hour pricing is the base layer for understanding training cost, model serving cost, and compute availability.

Lesson & Term of the Day
Term of the Day
On-demand compute
On-demand compute is capacity rented when needed without a long-term reservation. It is usually easier to start using, but it may be more expensive than committed capacity. For AI teams, on-demand pricing is useful for experiments, overflow demand, and workloads that do not justify a dedicated reservation.
