General-purpose AI model

An AI model that does many different tasks well. Because of that, others build all kinds of AI systems on top of it. The term is a legal category in the EU AI Act, and the makers of such models have duties under that law. The models trained with the most computing power face stricter rules. The law calls them general-purpose AI models with systemic risk. What counts is the range of tasks, so a model built for one narrow task stays outside the category, however large it is. Generative AI is defined by what it produces, and a general-purpose AI model by how many different tasks it does. A large language model is usually both.
