Cost-Aware, Governance-First RAG System with Adaptive LLM Routing
A production-inspired retrieval system for AI-governance question answering across the EU AI Act, GDPR, NIST AI RMF, and ISO/IEC 42001. Hybrid retrieval combines symbolic exact-match, BM25 and FAISS fusion, and cross-encoder reranking, built from scratch. A rule-based router then sends each query to a cheap or costly model tier, evaluated with RAGAS and a counterfactual comparison against an oracle.
