AI-901 is Microsoft’s entry-level exam for people starting a career in AI solution development on Azure. Passing it earns the Microsoft Certified: Azure AI Fundamentals credential. It replaced AI-900, which Microsoft retired on June 30, 2026.

Do not let the word “fundamentals” mislead you. This is no longer a purely conceptual exam. More than half the score sits in a skill area called implement AI solutions by using Microsoft Foundry, and Microsoft’s own audience profile now expects knowledge of Python syntax and familiarity with REST APIs, SDKs and CLIs. AI-900 asked you to describe things; AI-901 asks you to build small things.

What the exam covers

Skill areaWeight
Identify AI concepts and capabilities40–45%
Implement AI solutions by using Microsoft Foundry55–60%

Two areas only, which makes this a simpler exam to plan for than most. The first covers responsible AI, how generative models work, choosing a model, and recognising which AI workload fits a scenario. The second is hands-on: prompts, deploying a model, a small chat client, a single agent, text and speech, vision, and information extraction with Content Understanding.
