The paradigm worked well for FAQs, simple ticket routing, or basic conversational marketing. Yet the expectations of users—and the capabilities of modern large language models (LLMs)—have outgrown that narrow definition. ...

Introduction Large language models (LLMs) such as GPT‑4, Claude, and LLaMA have demonstrated remarkable abilities to generate fluent, context‑aware text. Yet, their knowledge is static—frozen at the moment of pre‑training—and they lack a reliable mechanism for accessing up‑to‑date, structured information. Retrieval‑Augmented Generation (RAG) addresses this gap by coupling LLMs with an external knowledge source, typically a vector store of unstructured documents. While vector‑based RAG works well for textual retrieval, many domains (e.g., biomedical research, supply‑chain logistics, social networks) are naturally expressed as graphs: entities linked by typed relationships, often enriched with attributes and ontologies. Knowledge graphs (KGs) capture this relational structure, enabling queries that go beyond keyword matching—think “find all researchers who co‑authored a paper with a Nobel laureate after 2015”. ...

While conversational agents remain valuable, the AI community is rapidly shifting toward agentic workflows, where autonomous agents not only talk but act in dynamic environments. These agents can plan, execute, and adapt without explicit human supervision, opening doors to applications ranging from automated DevOps to self‑optimizing recommendation engines. ...
