Aurora pgvector caps Bedrock Knowledge Bases at 2,000 dimensions in single precision

AWS's comparison of the three customer-managed backends credits OpenSearch with in-memory speed and S3 Vectors with sub-second queries at up to 90 percent lower storage cost. The Aurora spec sets a ceiling your embedding model has to fit under.

Axonius runs one agent per tenant on AgentCore, and tracks model cost the same way
