A hybrid AI technique known as RAG, which integrates retrieval systems with generative models, addresses the problem of outdated responses from AI models by incorporating real-time information from external sources to enhance output accuracy and relevance. While RAG offers benefits such as increased creativity, data control, and precision, it also presents challenges like data pipeline complexity, latency issues, and version control. The text outlines a step-by-step guide for building a RAG system using Python, including loading and splitting data, creating a vector store, and integrating a large language model (LLM) for generating responses. It highlights the importance of Continuous Integration/Continuous Deployment (CI/CD) with CircleCI to automate testing, integration, and deployment processes, ensuring reliable and fast updates while maintaining code quality. By adopting CI/CD workflows, RAG systems become more efficient, scalable, and adaptable to evolving technological demands, fostering a robust AI ecosystem.
