Amazon Bedrock Knowledge Bases review

A fully managed service for building RAG applications, tightly integrated with AWS data sources and models.

Verdict

Amazon Bedrock Knowledge Bases is the best managed RAG solution for companies committed to the AWS ecosystem, offering seamless integration with S3 and various vector stores.

What customers praise
