RAG with Amazon Bedrock – Part 1

Voiced by Amazon Polly


RAG stands for Retrieval-Augmented Generative. It refers to a class of natural language processing models that combines generative capabilities with information retrieval mechanisms. RAG models aim to enhance the generation of natural language text by allowing the model to retrieve and incorporate relevant information from a pre-existing knowledge base.

The architecture of a typical RAG model includes a generative language model, such as a transformer-based model, and a retrieval component. The retrieval component enables the model to search and retrieve information from a specified knowledge source, often a large database or a collection of documents. The generative model then uses this retrieved information to produce more contextually relevant and informed responses.

What is Amazon Bedrock?

Amazon Bedrock is a meticulously administered platform that provides a selection of high-performing foundational models (FMs) crafted by leading artificial intelligence enterprises such as AI21 Labs, Anthropic, Cohere, Meta, Stability AI, and Amazon through a unified API. Additionally, it furnishes an extensive array of functionalities essential for constructing creative AI applications, ensuring security, privacy, and ethical AI practices.

Utilizing Amazon Bedrock facilitates seamless experimentation and assessment of premier FMs tailored to your requirements. It enables confidential customization leveraging your data, employing methodologies like fine-tuning and the innovative approach of Retrieval-Augmented Generation (RAG).

Moreover, it empowers the creation of agents capable of executing tasks by interfacing with your enterprise systems and diverse data sources.

Knowledge base for Amazon Bedrock

Amazon Bedrock’s Knowledge Base empowers users to consolidate data sources efficiently. This reservoir of information becomes the cornerstone for building applications that employ the advanced technique of Retrieval Augmented Generation (RAG). Unlike traditional models, RAG enhances response generation by retrieving information from data sources, elevating the overall application intelligence.

Key Benefits of Knowledge Bases:

  • Retrieve And Generate API Integration: Configure your RAG application seamlessly using the Retrieve and Generate API. This API enables the application to query the Knowledge Base and generate responses dynamically based on the retrieved information. This integration enhances the responsiveness and relevance of your application’s output. This also helps store much more relevant data as a knowledge base, such as raw pdf files, doc files, and many other data sources that can be easily retrieved when calling the model.
  • Agent Empowerment with RAG: Elevate the capabilities of your agent by associating the Knowledge Base with it. This integration adds RAG capability to the agent, enabling it to reason through steps and provide more informed assistance to end users. This collaborative approach enhances user experience and problem-solving efficiency.
  • Custom Orchestration with Retrieve API: Take customization to the next level by creating a tailored orchestration flow in your application. Utilize the Retrieve API to fetch information from the Knowledge Base directly. This approach provides flexibility in handling specific data retrieval scenarios, allowing you to design a bespoke user experience.

Knowledge Base Setup

  • Begin by arranging and specifying the data sources you want to integrate into your knowledge base.
  • Transfer your data to a designated Amazon S3 bucket for storage and organization.
  • Process your data by creating embeddings using a foundational model, and then store these embeddings in a compatible vector store.
  • Establish the necessary infrastructure within your application or agent to inquire about the knowledge base, enabling it to provide enhanced and augmented responses based on the retrieved information.


Amazon Bedrock’s Knowledge Base is a game-changer for developers seeking to harness the power of information. Whether integrating RAG for dynamic response generation or empowering agents with advanced reasoning capabilities, the possibilities are vast. Developers can create intelligent applications that stand out in today’s competitive technological landscape by understanding and implementing the various ways to leverage the Knowledge Base. Unlock the true potential of your data with Amazon Bedrock’s Knowledge Base and revolutionize your application development journey.
