GKE Pod Snapshots Cut Model Load Times, and Move the Work to Snapshot Lifecycle Management
Google's GKE Pod snapshots now enable up to 89% faster startup times by checkpointing CPU and GPU memory states directly to Cloud Storage.
GKE Pod snapshots allow developers to save and restore the full running state of a workload, including memory, to significantly reduce cold-start latency for large models. The feature, now GA on GKE 1.35.3+, uses gVisor to checkpoint state. While performance gains are substantial—loading a 70B model in 37 seconds—success depends on strict parity between the snapshot environment and the target cluster's kernel and dr…
