October 22, 2026: Custom runtime images for ML Jobs (General availability)¶

Custom runtime images for ML Jobs are now generally available. You can build, validate, and register your own custom container images as Custom Runtime Environments (CREs), and then reference them when you submit ML Jobs on Container Runtime by using the runtime_environment="cre@<name>" format. Custom runtime images let you include specific packages, meet compliance and security requirements, integrate with existing CI/CD pipelines, and ensure reproducibility across environments.

Custom runtime images for Snowflake Notebooks remain in preview.
