When a user types a query, the system must generate a response in milliseconds, not seconds. This latency requirement becomes dramatically more complex when the inference service is globally distributed—the same model runs on clusters in North America, Europe, Asia‑Pacific, and possibly edge devices at the network edge. ...

Introduction Enterprises are increasingly turning to large language models (LLMs) to power conversational assistants, knowledge‑base search, and decision‑support tools. While LLMs excel at generating fluent text, they struggle with grounded, up‑to‑date factuality when the underlying data is scattered across documents, databases, and legacy systems. Graph Retrieval‑Augmented Generation (GraphRAG) addresses this gap by coupling an LLM with a knowledge graph that stores both entities and the relationships between them. The graph acts as a structured memory that the model can query, retrieve, and reason over, delivering context‑rich answers that are both accurate and explainable. ...

Introduction Large Language Models (LLMs) such as GPT‑4, LLaMA, and PaLM have transformed natural language processing, enabling capabilities ranging from code generation to conversational agents. However, the sheer size of these models—often exceeding tens or even hundreds of billions of parameters—poses a formidable challenge when it comes to inference latency. Users expect near‑real‑time responses, especially in interactive applications like chatbots, code assistants, and recommendation engines. Achieving low latency while maintaining high throughput requires a deep integration of software optimizations and high‑performance computing (HPC) architectures. ...

Yet, the same cloud‑centric mindset that powers ChatGPT or Claude also creates latency, privacy, and cost concerns for many real‑world use cases. Running LLM inference locally—whether on a laptop, edge device, or an on‑premise server—offers immediate responsiveness, data sovereignty, and the possibility of fine‑grained control over model behavior. ...
