What Is Checkpoint?

A checkpoint is a snapshot of model state saved to storage at intervals during training, used for failure recovery and for keeping results. Training usually pauses while it is written, so the slower the write, the longer the GPUs sit idle.

In the measurements

In measurements, saving a 65.6 GB full-model snapshot takes 94 s instead of 178 s (1.9×)R1.

Test jointly first, decide afterwards

Every engagement starts with a gated joint test of about 10 weeks. Four gates are passed in sequence; if one is missed, the project stops there, so you never pay for a benefit that was not demonstrated.
