An **AI design model** refers to a structured framework, methodology, or computational architecture used to create, train, and evaluate artificial intelligence systems. It encompasses how an AI system is conceptualized, including the selection of algorithms, data structures, training methods, and evaluation criteria, to achieve specific design goals such as pattern recognition, decision-making, or creative generation. This term can apply both to the conceptual design process of AI systems and to models that assist in design-related tasks (e.g., AI models used in graphic, product, or user experience design).
