Introduction The demand for real‑time machine‑learning inference has exploded across industries—from recommendation engines that serve millions of users per second to autonomous‑vehicle perception stacks that must make decisions within a few milliseconds. While training pipelines have long benefited from massive GPU clusters and sophisticated graph optimizers, production inference workloads present a different set of challenges: Latency guarantees – Many user‑facing services cannot tolerate more than a few tens of milliseconds of tail latency. Throughput pressure – A single model may need to process thousands of requests per second on a single node, let alone across a fleet. Heterogeneous hardware – Inference services often run on a mix of CPUs, GPUs, TPUs, and even specialized ASICs. Dynamic traffic – Request rates fluctuate dramatically throughout the day, requiring systems that can adapt on‑the‑fly. Two techniques have emerged as decisive levers for meeting these constraints: ...

In many of these domains, a distributed multi‑agent system (MAS) is the natural way to model autonomous decision makers that must cooperate, compete, and adapt to a shared environment. ...

Introduction The rise of large‑language‑model (LLM) agents—autonomous “software‑agents” that can plan, act, and iterate on tasks—has opened a new frontier for building intelligent applications. These agentic workflows often rely on vector embeddings to retrieve relevant context, rank possible actions, or store intermediate knowledge. As the number of agents, the size of the knowledge base, and the complexity of the orchestration grow, traditional monolithic vector stores become a bottleneck. Two complementary technologies address this scalability challenge: ...

Introduction Autonomous agents—whether they are fleets of delivery drones, self‑driving cars, or software bots managing cloud resources—must make rapid, coordinated decisions based on streams of sensor data, market feeds, or user requests. In many modern architectures these agents are not monolithic programs but distributed state machines that evolve their internal state in response to high‑velocity events. The challenge for engineers is to maintain correctness while pushing throughput to the limits of the underlying infrastructure. ...

Introduction Real‑time inference has become the linchpin of modern AI‑driven applications—from autonomous vehicles and industrial robotics to augmented reality and smart‑city monitoring. As these workloads scale, a single data‑center GPU can no longer satisfy the stringent latency, bandwidth, and privacy requirements of every use case. The answer lies in distributed AI systems that blend powerful cloud resources with edge computing nodes located close to the data source. However, edge devices are typically resource‑constrained, making it essential to shrink model size and computational complexity without sacrificing accuracy. This is where model distillation—the process of transferring knowledge from a large “teacher” model to a compact “student” model—plays a pivotal role. ...
