CoreWeave adds pre-staging for AI Object Storage to cut cold-start latency in LOTA cache workloads.
CoreWeave AI Object Storage now supports pre-staging objects into the LOTA cache.
A single HeadObject call triggers LOTA to fetch the complete object from backend storage and place it in the distributed NVMe cache, eliminating cold-start latency for training, inference, and checkpoint-restore workloads.
See the pre-stage cache release note for more information.

CoreWeave adds comprehensive Node Pool configuration management with staged updates, rollback support, and full configuration history visibility. Users can now track active and pending configurations and use cwic to upgrade Node Pools or roll back to earlier states.
CKS Node Pools now support comprehensive configuration management with staged updates, rollback capabilities, and full visibility into configuration history.
Node Pool configurations define the desired state for Nodes, including ncore image, GPU driver, and Kubernetes versions. The Node Pool Status now tracks the active configuration, staged pending configurations awaiting user approval, and a history of all applied configurations.
Use the CoreWeave Intelligent CLI (cwic) to upgrade Node Pools to pending configurations or roll back to previous configurations. See the Node configuration visibility and management release notes for more information.

CoreWeave adds RenameObject to AI Object Storage for fast, atomic server-side object renaming.
CoreWeave AI Object Storage now supports the RenameObject API for atomic, server-side object renaming.
The RenameObject API provides atomic rename operations within the same bucket, completing in milliseconds regardless of object size. Unlike copy-and-delete workflows, RenameObject updates metadata only—no data is copied and no temporary storage duplication occurs.
For more information, see the RenameObject release notes.

CoreWeave adds clearer usage visibility in the Usage by Product and Zone dashboard, showing measured and net usage side by side for GPUs, CPUs, Storage, and IP Addresses so customers can compare metered usage with billing-basis usage.
The Usage by Product and Zone dashboard now shows two usage layers for each resource type, making the difference between total metered usage and billing-basis usage visible.
The Usage by Product and Zone dashboard in CoreWeave Observe™ now displays two sets of cards for each resource type (GPUs, CPUs, Storage, IP Addresses):
- Measured usage: All metered usage before any exclusions are applied.
- Net usage: Usage after CoreWeave-level exclusions and adjustments. This is the basis for billing, subject to your contract terms (rates, discounts, and credits).
For more information, see the Usage by Product and Zone dashboard release notes.
