Baseten introduced BDN Sealed Volumes, a service for publishing read-only data once and mounting immutable, digest-addressed versions in deployments. Baseten says the feature can distribute model weights, checkpoints, container images, adapters, indexes, and other artifacts, with support in Baseten CLI 1.1.0 or newer and Truss 0.18.30 or newer. The announcement also says deleted versions remain restorable for seven days, while volume mounts are unavailable on T4 and L4 instances.
