AI-900 vs AZ-900: Which Azure Fundamentals Cert Should You Take?

Microsoft offers two popular entry-level fundamentals certifications that people confuse: Azure AI Fundamentals (AI-900) and Azure Fundamentals (AZ-900). Both are concept-first and require no coding, but they cover different ground. Independent comparison, not affiliated with Microsoft.

What each one covers

• AZ-900 (Azure Fundamentals): broad cloud and Azure literacy. Core Azure services, cloud concepts, pricing, governance, and security.
• AI-900 (Azure AI Fundamentals): AI and machine learning literacy on Azure. Common AI workloads, ML principles, computer vision, natural language, generative AI, and responsible AI.

Which to take

• You want general Azure and cloud credibility: AZ-900 is the base.
• You want to signal AI capability specifically: AI-900 is the more differentiated, current choice in 2026.
• You are new to cloud entirely: AZ-900 first gives you the foundation AI-900 loosely assumes.
• You already know cloud basics and care about AI: go straight to AI-900.
