This is part of a series of articles to introduce Generative AI and step-by-step process with code sample to build GenAI Application; Part-1 ( GenAI Introduction ), Part-2 ( Building GenAI App using Spring Boot and Amazon Bedrock ) and Part-3 ( Building GenAI App with Proprietary data ). In previous article , we have built GenAI Application (simple ChatBot) using Amazon Bedrock Model ( Claude 3 Haiku ) and Spring Boot . This App generates answers based on training dataset (public information) of the Model. What about if we could restrict or refine this Model with proprietary data (like Company details, Sales, Customer records) as add-on Knowledge Base instead of retraining the Model . This would allow to serve personalized and contextual response, e.g. generating response with Customer's last order details. In this article we are going to enhance our GenAI application to accept proprietary data. Prerequisites Spring Boot v3, JDK 17 AWS SDK v2.x AWS IAM account with API credentials ...
