AWS adds SOCI index image acceleration for SageMaker AI
What happened
On 28 October 2026, the AWS Machine Learning Blog announced that AWS has introduced a Seekable OCI (SOCI) index for Amazon SageMaker AI training and processing jobs. With the index, container images are loaded lazily, cutting job start times from minutes to seconds. The feature is in rollout, and the report gives no details on supported Regions, pricing or compatibility with existing image build workflows.
