Enhanced Information Retrieval in Amazon Bedrock
AWS introduces AgenticRetrieveStream, a new API for Amazon Bedrock designed to improve the handling of complex multi-part queries compared to traditional methods.

What happened?
Amazon Web Services (AWS) has launched the AgenticRetrieveStream API for its Amazon Bedrock service. This new feature is specifically designed to handle 'multi-part questions'—complex queries that require more than a single information retrieval step. It complements the existing Retrieve API by providing a more sophisticated retrieval strategy.

”This post focuses on why classic retrieval falls short on multi-part questions, how the AgenticRetrieveStream API works (including request construction and trace parsing), and when to choose it over the standard Retrieve API.”
Why it matters
Traditional information retrieval methods, known as 'classic retrieval', often face limitations when confronted with queries containing multiple components or implicit contexts. The AgenticRetrieveStream API enables a more agentic approach, where the system can break down complex questions and retrieve relevant information progressively. This results in more accurate and comprehensive answers to intricate requests.
Who is affected?
The new function is primarily aimed at developers and organisations using Amazon Bedrock to build generative AI applications. By handling complex questions more effectively, they can create more intelligent and useful AI assistants, chatbots, and knowledge systems for their end users.
What else you should know
The AWS Machine Learning Blog details how the AgenticRetrieveStream API functions, including query construction and trace data analysis, providing technical insights for implementation.
