Amazon Bedrock Managed Knowledge Base adds single-shot and retrieval-only modes
Overview
Amazon Bedrock Managed Knowledge Base now supports single-shot Retrieval Augmented Generation (RAG) and retrieval-only requests through AgenticRetrieveStream, alongside its existing agentic retrieval, according to an AWS Machine Learning Blog post.
Single-shot RAG searches a knowledge base once and uses a foundation model to generate an answer. Retrieval-only requests return matching passages without generating one.
The mode is selected per request with the maxAgentIteration parameter, which now accepts values from 0 to 5. The AWS post explains how these settings work and when to use each mode.
