Pile height: 1 mm
Could fill: a few grains

If you did one step a second: 1 second

How this is estimated

Each chip does about 4 × 10¹⁴ useful FLOPs per second and draws about 1.5 kW, cooling included. Train for longer and you need fewer chips and less power, but the same energy. Counts only the final training run, not experiments or later use.
