Introduction The explosive growth of large language models (LLMs) over the past few years has been fueled by two intertwined forces: ever‑larger parameter counts and ever‑longer context windows. While the former has been the headline‑grabbing narrative, the latter is quietly becoming the real bottleneck for many production workloads. Traditional self‑attention scales quadratically with the number of input tokens, meaning that a modest increase in context length can explode both memory consumption and latency. ...

Historically, the sheer computational demand of these models forced developers to rely on cloud‑hosted APIs (OpenAI, Anthropic, Cohere, etc.). While cloud APIs provide a low‑friction entry point, they carry latency, bandwidth, cost, and privacy penalties that become untenable for edge devices such as drones, wearables, industrial controllers, and IoT gateways. ...

Introduction Enterprises are increasingly deploying agentic systems—autonomous software agents that can reason, plan, and act on behalf of users. Whether it’s a conversational assistant that resolves support tickets, a real‑time recommendation engine, or a robotic process automation (RPA) bot that orchestrates back‑office workflows, the backbone of these agents is inference: feeding a request to a trained machine‑learning model and receiving a prediction fast enough to keep the interaction fluid. For a single model, serving latency can be measured in tens of milliseconds on a powerful GPU. However, production‑grade agentic platforms must handle: ...
