$U \in (0,1]$

Why this formula appears here

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 bookkeeping identity stated to make one point precisely: U appears in the denominator, so it multiplies with, rather than merely adds to, every other lever in this article. Halving fixed cost through better batching and halving it again through utilization gains compound rather than add. (Analysis: an accounting identity…
