From GPT‑4 to Claude, these models have become the backbone of many developer‑centric tools—code completion, documentation generation, automated testing, and even full‑stack scaffolding. Yet, the dominant deployment paradigm remains cloud‑centric: developers send prompts to remote APIs, await a response, and then act on the output. ...

Introduction The past few years have witnessed an explosion of interest in retrieval‑augmented generation (RAG) as a way to overcome the limited context windows of large language models (LLMs). By pulling relevant documents from an external datastore at inference time, RAG can inject up‑to‑date knowledge, reduce hallucinations, and keep token usage low. However, as LLMs grow from research curiosities to core components of production‑grade workflows, the shortcomings of classic RAG become increasingly apparent: ...

Historically, the most powerful LLMs—GPT‑4, Claude, PaLM‑2—have lived in massive datacenters, accessed via API calls. While this cloud‑first paradigm offers raw performance, it also introduces latency, bandwidth costs, and privacy concerns. ...

Introduction Large language models (LLMs) such as GPT‑4, Claude, LLaMA, and Gemini have transformed the way we build conversational agents, code assistants, and knowledge‑heavy applications. Yet, even the most capable LLMs suffer from a fundamental limitation: they cannot reliably recall up‑to‑date facts or proprietary data that lies outside their training corpus. Retrieval‑Augmented Generation (RAG) solves this problem by coupling an LLM with an external knowledge store. The store is typically a vector database that holds dense embeddings of documents, passages, or even multimodal items. When a user asks a question, the system performs a semantic similarity search, retrieves the most relevant vectors, and injects the corresponding text into the LLM prompt. The model then “generates” an answer grounded in the retrieved context. ...
