How to secure RAG applications with Fine-Grained Authorization: tutorial with code

This tutorial demonstrates how to secure Retrieval Augmented Generation (RAG) applications using WorkOS Fine-Grained Authorization (FGA). The goal is to ensure users only see results from documents they have permission to access. The process involves defining an authorization model with FGA, processing documents for vector search, implementing runtime access control, and managing document sharing dynamically. By integrating FGA with Pinecone's vector database, the tutorial showcases how to efficiently check user permissions and filter search results based on user access levels.
