What is AI, Actually?

AI stands for Artificial Intelligence. Under the EU AI Act, it does not just mean software that learns from data. The legal definition is broader: an AI system is a machine-based system designed to operate with varying levels of autonomy and that infers from the input it receives how to generate outputs such as predictions, content, recommendations, or decisions (Article 3(1)).

In everyday language, that means the system does more than execute a fixed list of human-written instructions step by step. It infers patterns or rules from inputs to produce outputs. That can include machine learning, statistical approaches, and some rule-based or knowledge-based systems.

This matters because not every automated system is AI under the Act. A simple calculator or fixed if/then script is usually not. But the legal definition is broader than "machine learning only."
