DALL·E The Layered AI Stack And The Semiconductor Roots Artificial intelligence operates through a hierarchy of interdependent layers, each transforming data into decisions. From the underlying silicon to the visible applications, every tier depends on semiconductor capability to function efficiently and scale economically. The AI stack can be imagined as a living structure built on four essential layers: silicon, system, software, and service. Each layer has its own responsibilities but remains fundamentally connected to the performance and evolution of the chips that power it. Together, these layers convert raw computational potential into intelligent outcomes. At the foundation lies the silicon layer, where transistor innovation determines how many computations can be executed per joule of energy. Modern nodes, such as those at 5 nm and 3 nm, make […]
