unit economics

Fleet dollars per second over tokens per second, times a million: a worked $2.78, the utilization term that turns it into $6.94, and why batch is the lever that moves it by 50x.

Dollars per FLOP from the GPU price and the MFU, times 6N: a 70B training token costs about three quarters of a microdollar, and the whole 15T-token run follows in one multiplication. The chain, the comparison to an inference token, and why the training token is cheaper.
