  title: Amazon SageMaker Inventory Models
  summary: List registered models and describe the most recently created one in detail.
  description: >-
    A model catalog inspection flow. The workflow lists the account's registered
    models sorted by creation time, branches on whether any exist, and when
    there is at least one describes the newest model to surface its primary
    container image, artifact location, and execution role. Each step spells out
    its request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
