Amazon SageMaker AI Speeds Up Training with SOCI-Indexed Container Images

Amazon SageMaker AI now supports SOCI-indexed container images that slash training job startup times to seconds, cutting GPU idle time by up to 90% during image pulls. The feature lazy-loads only essential files while streaming the rest in the background—just reference a SOCI-indexed image from Amazon ECR, and it works automatically across all AWS Regions where SageMaker AI is available.
