New in CoreWeave AI Object Storage: Cross-Region Writes and Archive Storage
CoreWeave, Wednesday, September 16th, 2026
CoreWeave adds cross-region writes and an archive tier to its AI Object Storage service.
CoreWeave announced two additions to AI Object Storage: cross-region write support and a lower-cost archive storage tier.
Cross-region writes let training and inference pipelines write data once and have it available across regions without a separate replication step.
The archive tier targets large datasets and checkpoints that must be retained but are infrequently accessed.
The post covers pricing structure, consistency behavior, and how the features fit into large-scale training workflows that span multiple data centers.
