Google's conceptual model that organizes the generative AI ecosystem into 5 layers: Infrastructure (chips, data centers), Models (foundation models), Platforms (tools for building and managing solutions), Agents (systems that reason and act), and Applications (the final product visible to the user).
In GENAI-L (Domain 1, section 1.3) the exam asks you to identify which layer a specific Google Cloud product belongs to — e.g. Gemini is a Model, Agent Platform is a Platform, the Gemini app is an Application.
Layers of the generative AI landscape is a concept that can show up on the exam. Check the full guide to see it in context.
