Modern AI Stack: A Guide to Production AI Architectures

This guide explores the Modern AI Stack, a distributed architecture essential for building reliable production AI systems beyond simple API wrappers. It details key components like Large Language Models (LLMs), semantic memory (Embeddings and Vector Databases), retrieval pipelines (RAG), and orchestration layers (LangGraph, n8n). The article emphasizes the distinction between experimental AI prototypes and production-grade engineering, highlighting the probabilistic nature of LLMs and the need for specialized infrastructure to constrain and monitor them. AI
