The total count of vector dimensions is a good indicator of the resources required — a simple number you can calculate, rather than abstract Read/Write units or CPU cycles. You are also billed for persistent and backup storage of objects and their embeddings.

The minimum covers the baseline cluster cost and includes charges for Vector Dimensions and Storage: $45/month on Flex and from $400/month on Premium. Backups are charged on top, based on data volume and retention.

Compression does not change the number of vector dimensions stored, but it reduces the memory and compute required for search. More aggressive compression yields greater efficiency, reflected in discounted list prices for vector dimensions.

Yes — list prices for all vector-dimension rates vary by cloud provider and region to reflect regional cost variations.

Weaviate Cloud uses the Weaviate open-source project, wrapped in a managed service that removes administration overhead and adds features like the Embedding Service, Query Agent, and Data Import.

Yes. Weaviate Cloud is SOC 2 audited, and Enterprise Cloud on AWS is HIPAA compliant. See the Trust Portal for details.

We updated the Weaviate Cloud price book. Two things changed:

RQ-4 compression is now available on HNSW collections and has its own price, which sits between RQ-1 and RQ-8.

Backups are billed at a corrected rate per GiB. The rate now starts from the same base on AWS, GCP and Azure, and then varies by region.

To usage from 1 September 2026. The running costs in your Weaviate Cloud console already reflect them.

Backups are on by default for every cluster, so the change shows up on your backup line. Whether that line went up or down depends on which cloud and region your clusters run in. For some customers it went up, for others it came down. If you use RQ-4 compression, those collections are now billed at the RQ-4 rate. Everything else on your bill is unchanged.

Backup rates used to be set separately for each cloud, and some of them were out of line with what hyperscalers charge us to host your backups. The new rates use one common base with regional adjustments, so pricing is consistent and fair wherever you run.

List prices are on weaviate.io/pricing. The console shows your cluster's current running cost.
