Which element does NOT belong to the infrastructure layer of Gen AI systems?

User Experience Design does not belong to the infrastructure layer of Generative AI systems because it focuses primarily on the interaction between users and the applications or systems, rather than on the underlying technical components that support the functioning of those systems. The infrastructure layer comprises elements such as high-performance storage, networking, and software, which are all essential for the operational capabilities, performance, and scalability of AI systems. These components work together to ensure that data is efficiently stored, transmitted, and processed, providing the necessary support for developing and running AI applications. In contrast, User Experience Design emphasizes how users perceive and interact with technology, making it part of the application and design layer rather than the foundational infrastructure.
