Where the article explains it

Here $C_{\text{fixed}}$ is the amortized hardware and facility cost per unit time, $C_{\text{energy}}$ the energy cost per unit time, $T_{\max}$ the chip’s maximum achievable token throughput under ideal batching, U $\in$ (0,1] the realized utilization fraction, and m a margin term.

The passage around this formula

Here $C_{\text{fixed}}$ is the amortized hardware and facility cost per unit time, $C_{\text{energy}}$ the energy cost per unit time, $T_{\max}$ the chip’s maximum achievable token throughput under ideal batching, U $\in$ (0,1] the realized utilization fraction, and m a margin term. This is not a model any provider discloses or that this article claims to have measured; it is a…
