aws-samples/aws-genai-rfpassistant
This repository contains the code and infrastructure as code for a Generative AI-powered Request for Proposal (RFP) Assistant leveraging Amazon Bedrock and AWS Cloud Development Kit (CDK).
Implements a multi-engine Retrieval Augmented Generation (RAG) system using Amazon OpenSearch Serverless, DynamoDB, and S3, processing RFP documents through AWS Step Functions and Batch for embedding and indexing. The architecture combines AppSync GraphQL APIs for real-time chat interactions with Lambda-driven document processing pipelines, while supporting multiple embedding models (Bedrock Titan, Cohere) and cross-encoder reranking via SageMaker for improved retrieval accuracy.
