What changes after AI-900
AI-900 retired on June 30, 2026, according to the AI-900 study guide. You can no longer take that exam. If you already earned Azure AI Fundamentals, your certification does not expire or require renewal, as Microsoft explains in its renewal FAQ. Exam retirement and certification retirement are separate events. Your existing credential does not automatically become a new certification.
Read the AI-901 objectives carefully
The AI-901 study guide assigns 40–45% to AI concepts and 55–60% to implementation with Microsoft Foundry. These are objective weights, not a count or proportion of exam labs. The guide also expects knowledge of Python syntax and programming techniques, plus familiarity with REST APIs, SDKs and CLIs. Use those expectations to identify gaps: understanding a concept and tracing an application’s request are different study tasks.
Exercise: keep an answer within its source
In Microsoft Foundry, supply this fictional library policy as context for a model request: “Members can borrow five books for fourteen days. Reference books cannot leave the library.” Add this instruction: “Answer only from the supplied policy. If it does not contain the answer, say so.”
Ask: “How many books can I borrow, and for how long?” Expect both limits, with no invented conditions. Then ask: “Can I borrow a reference book?” The answer must preserve the exception rather than applying the general borrowing rule.
Finally, ask: “What is the late-return fee?” The expected result is an acknowledgment that the policy does not specify a fee. Any invented amount is a failure. Record the response, revise the instruction, and repeat all three questions to check that the revision has not introduced another error.
This is a learning exercise, not an exam item. Continue with AI fundamentals practice and use the guide to plan further review.
