Can I mount an Object Storage bucket as a filesystem?

Yes, but mounting Object Storage as a POSIX filesystem is a community-supported workflow rather than a managed CoreWeave feature. CoreWeave AI Object Storage is S3-compatible, so FUSE-based tools such as s3fs-fuse, Mountpoint for S3, and JuiceFS can be configured against CoreWeave’s endpoints. Inside a CoreWeave cluster, point the tool at the LOTA endpoint http://cwlota.com to use the on-Node cache; outside a cluster, use https://cwobject.com (requires TLS v1.3). For most read-heavy workloads, especially training pipelines on GPU Nodes, LOTA combined with a native S3 SDK performs better than a FUSE mount. Contact support if you need help selecting or configuring a FUSE-based mount for a specific workload.
