Introduction The explosion of large language models (LLMs) over the past few years has fundamentally changed how developers think about natural‑language processing (NLP) and generative AI. Yet, the sheer size of these models—often hundreds of billions of parameters—means that most deployments still rely on powerful cloud infrastructures. A growing counter‑trend is the rise of small language models (SLMs) that can run locally on consumer devices, edge servers, or specialized hardware accelerators. When these models are coupled with first‑party AI agents—software components that act on behalf of a user or an application—they enable a local‑first experience: data never leaves the device, latency drops dramatically, and privacy guarantees become enforceable by design. ...

Yet a growing segment of developers, enterprises, and regulators is demanding local intelligence—AI that runs on‑device or within a controlled on‑premises environment. This shift is not merely a reaction to data‑privacy concerns; it opens up opportunities to build agentic workflows that are autonomous, context‑aware, and tightly coupled with the user’s own data. ...

Their impressive capabilities have spurred a wave of cloud‑centric services, where the heavy computational lift is outsourced to massive data centers. While this paradigm works well for many consumer applications, it raises three critical concerns for edge‑centric, privacy‑first workflows: ...

Introduction Federated learning (FL) has emerged as a compelling paradigm for training machine learning models across a network of edge devices while keeping raw data localized. In its classic formulation, a central server orchestrates training rounds: it collects model updates from participants, aggregates them (typically via weighted averaging), and redistributes the improved global model. While this centralized FL model works well for many scenarios, it suffers from several practical limitations: ...
