Amazon Bedrock Managed Knowledge Base adds single-shot RAG and retrieval-only via AgenticRetrieveStream
Amazon Web Services updated Bedrock’s Managed Knowledge Base to support single-shot Retrieval-Augmented Generation (RAG) and retrieval-only requests through the AgenticRetrieveStream API. Developers can now choose per request between retrieval-only (no foundation model calls), single-shot RAG (one model call to generate an answer), or agentic retrieval (multiple planning/retrieval iterations controlled by maxAgentIteration).
