  "account": "SageMaker AI now offers SOCI-indexed images to speed up training jobs. This innovative technology reduces container image download time, which traditionally adds significant overhead to every job. The SOCI indexing process enables lazy loading of container images, meaning only necessary files are fetched initially, with the rest streamed in the background. This results in faster job starts and lower costs, as image download time is taken off the critical path.\n\nTo implement SOCI indexing, you can point to a pre-indexed AWS Deep Learning Container (DLC) or add an index to your own image. No changes are needed to your job definition or data channels. In benchmark tests, SOCI-indexed images started training containers in seconds, with no impact on training performance. The technology saved up to 90% of GPU idle time during image pulls, making it a significant improvement for hyperparameter tuning, quick experiments, and short processing jobs where image download can dominate total runtime.",
  "summary": "Seekable OCI (SOCI) indexing for Amazon SageMaker AI training and processing jobs takes full container image download off the critical path. SageMaker AI lazy-loads your image to start containers in seconds instead of minutes, with no changes to your job definition. See the benchmarks and how to adopt it.",
