What it means
AI-900 is a Fundamentals-tier credential in Microsoft's numbering scheme. The official study guide lists the skills measured, including AI workloads and considerations, fundamentals of machine learning, computer vision, natural language processing, and generative AI workloads on Azure — definitional understanding rather than developer-level implementation.
