Hybrid AI Assistant Architecture: When to Use NLU, RAG, Deterministic Flows, and LLMs
TL;DR Enterprise assistants should not send every request directly to an LLM. A production-ready assistant needs a routing architecture that selects the right pattern for the job: deterministic flows for controlled tasks, NLU for intent routing, RAG for grounded knowledge answers, LLMs for synthesis and flexible language, and human handoff for ambiguity, risk, or exception […]
