Explore the transformative potential of Retrieval Augmented Generation (RAG) in development workflows through this 30-minute conference talk from Code BEAM Europe 2024. Discover how RAG techniques, powered by Large Language Models and embedding models, enable sophisticated information retrieval from documents using imprecise search terms in ways traditional full-text indices cannot match. Learn about the current state of RAG technology, including capabilities of online models and performance expectations from local setups. Examine the specific application of RAG techniques to codebases, with particular focus on Elixir as both an input codebase and processing entity. Understand how coding style and ingestion processes influence the effectiveness of RAG results, and gain practical insights into implementing RAG in your development environment to empower your team's productivity and code comprehension.
