What is AI?
The image is a diagram that Nvidia CEO Jensen Huang described in December 2025 as the "five-layer cake" of Artificial Intelligence.
This is a very useful and illustrative metaphor that clearly structures the fundamental components necessary for the functioning and development of artificial intelligence (AI). It helps us understand how the different elements of the AI technology ecosystem depend on each other, from the lowest to the highest level.
Applications: The layer of user interfaces and software.
Models: The layer of AI algorithms and architectures.
Infrastructure: The layer for data centers and networks.
Chips: The hardware layer, including processors and graphics accelerators.
Power: The fundamental layer required to power all AI components.
