Amazon SageMaker HyperPod adds model caching to cut inference cold starts
Amazon SageMaker HyperPod now supports model caching for inference, pre-loading model weights and container images onto cluster nodes so pods read from local NVMe storage instead of downloading over the network.
The change targets cold starts, which the source says can drop from tens of minutes to seconds. Model caching pre-loads model weights and container images onto cluster nodes. Pods then read from local NVMe storage rather than downloading over the network. The source also explains how to enable it.
