Equation 4 · Part 1 · How AI Inference Economics Actually Work

Symbol T_max

Tmax⁡T_{\max}
Tmax⁡T_{\max}

What this part means

the chip’s maximum achievable token throughput under ideal batching.

Its job in the formula

TmT_max is a part of this expression. Its role is fixed by the surrounding article and by the operations shown in the formula.

Where the article explains it

Here CfixedC_{\text{fixed}} is the amortized hardware and facility cost per unit time, CenergyC_{\text{energy}} the energy cost per unit time, Tmax⁡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 CfixedC_{\text{fixed}} is the amortized hardware and facility cost per unit time, CenergyC_{\text{energy}} the energy cost per unit time, Tmax⁡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:…
