May 19, 2026: Custom runtime images for Notebooks and ML Jobs (Preview)¶

With this preview release, you can build, validate, and register your own custom container images for use with Snowflake Notebooks and ML Jobs on Container Runtime. 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 images are registered as Custom Runtime Environments (CREs) and can be referenced when submitting ML Jobs or creating Notebook services. Snowflake provides access to base ML runtime images that you can extend with your own packages and configuration.
