High-Level Architecture and Components for a Generative AI-Based RAG Solution

Learn About Amazon VGT2 Learning Manager Chanci Turner

In the competitive landscape of the public sector, the ability to swiftly respond to Requests for Proposals (RFPs) with high-quality submissions can significantly influence the outcome of multi-million-dollar opportunities. As AWS partners face the challenge of enhancing their go-to-market strategies while ensuring proposal excellence, generative AI has emerged as a transformative solution.

This article offers AWS partners a practical framework for implementing Retrieval Augmented Generation (RAG) solutions that can revolutionize their proposal development processes. Leveraging RAG technology on AWS allows partners to dramatically decrease the time needed for proposal research and initial drafts, enabling teams to concentrate on strategic endeavors that boost win rates. Whether responding to Requests for Information (RFIs), RFPs, or crafting unsolicited proposals, an effective RAG solution can harness your organization’s collective expertise and previous achievements to produce high-quality proposals and responses in mere hours instead of days.

Here, we present a detailed guide for building your own RAG solution on AWS, complete with open-source instructions and best practices. Learn how to utilize the technology that powers enterprise-grade proposal automation while upholding security, compliance, and content quality.

Core Components of a Generative AI-Based RAG Solution

Data Ingestion

This component involves gathering, processing, and storing data in a format suitable for foundational models to yield relevant responses. A robust solution should:

• Support diverse data sources and formats: Capture data from various sources, including multiple file types, cloud storage, network drives, and web crawling.
• Provide versatile processing: Offer diverse embedding models tailored for distinct data types, such as language models for different languages or models for images and videos.
• Include generic embeddings: Employ generative AI frameworks that provide generic embeddings for ease of use in non-specific applications.
• Storage options: Implement simple index or vector-based storage for generated embeddings. For extensive, complex datasets requiring semantic search capabilities, a vector database is recommended, while simpler datasets can utilize a straightforward index.

Foundation Models

An effective solution should facilitate the use of various models seamlessly. Key features include:

• Amazon Bedrock: This service allows access to multiple foundation models from vendors like Anthropic, Cohere, and AI21 Labs, as well as AWS’s new Amazon Nova Model, through an easy API without incurring high infrastructure costs.
• Amazon SageMaker: For specific security needs and hosting requirements, Amazon SageMaker offers scalable GPU-based servers to host models from various vendors, including Meta and HuggingFace, or custom-built models.

Fine-tuning Responses from General-Purpose Large Language Models

• Response Tuning: This allows adjustments to parameters such as temperature and top-p, which help minimize inaccuracies and control the diversity of generated outputs. Features like temperature and top-p should be available to ensure relevant and suitable responses.
• Domain-Specific Datasets: The capability to integrate customized datasets enables accurate responses tailored to specific industries, such as incorporating previous RFx materials for particular verticals.
• Prompt Engineering: The ability to guide generative AI solutions to produce desired outputs should be a fundamental feature of your chosen solution.

User Interface

• User Application: A user-friendly interface, whether web-based or mobile, allows users to interact with the system efficiently by inputting queries and receiving generated responses.
• Access Control: The interface should support access control to ensure authorized usage of the generative AI solution and datasets. Integrating with AWS Identity and Access Management (IAM) allows for secure authentication and authorization.

Getting Started for Partners

To facilitate a swift deployment of solutions in partner or customer accounts, two options are provided, allowing partners to showcase multiple business use cases tailored to their needs. These solutions can be operational within hours, requiring minimal technical expertise to initiate RAG-based generative AI systems.

• AWS GenAI Chatbot: This solution offers ready-to-use code, enabling experimentation with a variety of large language models (LLMs) and multimodal language models in your own AWS account. Supported model providers include:
  • Amazon Bedrock: A broad array of models from AWS and third-party vendors like Anthropic and Cohere.
  • Amazon SageMaker: Self-hosted models from Foundation, Jumpstart, and HuggingFace.

  The guide for deploying this solution can be found in the provided GitHub link. For a comprehensive architecture document and source code, please refer to the relevant GitHub link.

• Amazon Bedrock in SageMaker Unified Studio: Alternatively, partners can utilize Amazon Bedrock in SageMaker Unified Studio, an integrated environment designed to enable developers to quickly build and customize generative AI applications.

By engaging with the resources and tools available, partners can enhance their capabilities and accelerate their proposals.
