KEY TAKEAWAYS
- • Enterprise agentic retrieval places a reasoning agent in the retrieval loop.

- • The AgenticRetrieveStream API provides multi-turn planning and cited answers.
- • The solution includes CloudWatch dashboards and built-in evaluation features.
From RAG to Agentic Retrieval
Classic Retrieval Augmented Generation does one retrieval and one generation. Enterprise agentic retrieval puts a reasoning agent in the loop to decide whether and what to retrieve, choose relevant knowledge bases, and compose a grounded answer.
Managed vs. Do-It-Yourself Knowledge Bases
Amazon Bedrock manages ingestion, storage, indexing, and retrieval for you on the Managed Knowledge Base, eliminating the need to provision a vector database. The customer-managed option remains available when you want to operate your own vector store.
