Introduction Retrieval‑Augmented Generation (RAG) has become the de‑facto pattern for building knowledge‑aware large language model (LLM) applications. By coupling a generative model with a vector store that holds dense embeddings of documents, code, or product data, RAG systems can ground responses in up‑to‑date facts, reduce hallucinations, and dramatically cut inference costs. While prototypes can be built with a single‑node FAISS index or a managed SaaS offering, moving to production‑grade workloads introduces a new set of challenges: ...

While model size and capability have exploded, user experience hinges on latency—the time between a request and the model’s first token. At the same time, many applications demand high throughput, processing thousands of concurrent queries per second (QPS). ...

Introduction Retrieval‑Augmented Generation (RAG) has emerged as a powerful paradigm for building language‑model applications that combine the creative flexibility of generative AI with the factual grounding of external knowledge sources. In a RAG pipeline, a vector database (or “vector store”) holds dense embeddings of documents, code snippets, product catalogs, or any other textual artefacts. When a user query arrives, the system performs a similarity search, retrieves the most relevant pieces of information, and feeds them into a large language model (LLM) to produce a context‑aware response. ...

From GPT‑4 to Claude and LLaMA, these models can generate fluent text, answer questions, and even write code. Yet, when they are asked about domain‑specific knowledge—such as a company’s internal policies, a research paper, or a product catalog—their answers can be hallucinated, outdated, or simply wrong. ...

Introduction Retrieval‑Augmented Generation (RAG) has quickly become the de‑facto architecture for building knowledge‑aware applications powered by large language models (LLMs). By coupling a retrieval engine (often a vector store) with a generative model, RAG enables systems to answer questions, draft documents, or provide recommendations that are grounded in up‑to‑date, domain‑specific data. While prototypes can be assembled in a few hours using libraries like LangChain or LlamaIndex, moving a RAG pipeline to production introduces a whole new set of challenges: ...
