AWS cuts the idle startup wait you pay for on AI training jobs

Why it matters

Teams training AI on AWS stop paying for several minutes of image download on every job, and wait less to start.

Ask your team

How many minutes per training job do we spend downloading container images, and what does that cost monthly?

What happened

AWS added (SOCI) indexing to SageMaker AI Training and processing jobs. Container images now load lazily, fetching only the parts needed, instead of downloading in full before the job starts.
