The honest brief

Pinecone

The zero-ops default: fully managed serverless with no infra to run, so teams ship RAG fast without a platform engineer.

  • No infra to provision or operate
  • Fast time-to-production
  • Low-latency reads at scale
  • Integrates with every major framework
  • No self-host option
  • Cost climbs at large scale
  • Closed source; potential lock-in

Amazon S3 Vectors

Pay only for storage and queries — AWS claims up to 90% lower cost than dedicated vector DBs for large, infrequently queried indexes.

  • Two billion vectors per index
  • S3 durability and elasticity
  • No idle compute costs
  • Native Bedrock Knowledge Bases integration
  • Locked to the AWS ecosystem
  • Cold queries are sub-second, not low-latency
  • Up to 100 results per query
