Foundational Model

fown-DAY-shuhn MOL-dl /fɑʊnˈdæɪʃən ˈmɒdl/

A large, general-purpose model pre-trained on a broad spectrum of mainly unlabelled data, using self-supervised learning techniques. Instead of building a new model from scratch, organisations start with a foundation model and adapt it (through prompting, fine-tuning, or add-ons). Many generative AI systems are built on foundation models.
