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 Artificial intelligence (AI) has moved from the cloud‑centered data‑science lab to the edge of the network where billions of devices generate and act on data in milliseconds. Whether it’s an autonomous drone avoiding obstacles, a retail kiosk delivering personalized offers, or an industrial sensor triggering a safety shutdown, the common denominator is real‑time decision making. At the heart of many modern AI systems lies a vector database—a specialized storage engine that indexes high‑dimensional embeddings generated by deep neural networks. These embeddings enable similarity search, nearest‑neighbor retrieval, and semantic matching, which are essential for recommendation, anomaly detection, and multimodal reasoning. ...

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. ...

Introduction Artificial intelligence has traditionally been a cloud‑centric discipline. Massive language models (LLMs) such as GPT‑4, Claude, or Gemini are hosted on powerful data‑center GPUs, and developers access them through APIs that stream responses over the internet. While this model has powered spectacular breakthroughs, it also introduces latency, bandwidth costs, privacy concerns, and a dependency on continuous connectivity. A growing counter‑movement—Local‑First AI—aims to bring intelligence back to the user’s device. By running small language models (SLMs) directly in the browser, we can achieve: ...
