Training run — cost & time
Estimate a training run end to end: model parameters and tokens (6·P·T FLOPs), MFU, cluster size, and goodput → wall-clock days, GPU-hours, rental cost, facility energy, and emissions.
Training run — time, cost, energy & CO₂
8.1 days · $4.5M rental
Compute (6·P·T)6.3×10²⁴ FLOPs
GPU-hours1.94M
Facility energy (incl. host + PUE)3,033 MWh (~$0.24M)
Emissions at 350 gCO₂/kWh1,062 t CO₂
MFU and goodput compound: 40% MFU × 90% goodput means ~2/3 of paid FLOPs never reach the loss curve. The gap between ~90% and ~96% goodput is checkpointing and cordon policy → Ch 12.2.
