AI-901 is Microsoft's exam titled Microsoft Azure AI Fundamentals. It replaced AI-900, which retired on June 30, 2026. The certification name did not change: you still earn Microsoft Certified: Azure AI Fundamentals. Only the exam underneath it was swapped, and the content was rewritten heavily.

Yes. AI-900 retired on June 30, 2026. The Azure AI Fundamentals certification page now lists only AI-901 as its exam. If you already passed AI-900 you keep the certification and Microsoft fundamentals certifications do not carry an annual renewal, so there is nothing you need to do.

What are the AI-901 domain weights?

Two domains, down from five on AI-900. Identify AI concepts and capabilities is 40 to 45 percent. Implement AI solutions by using Microsoft Foundry is 55 to 60 percent, making a single product the majority of the exam.

Is AI-901 harder than AI-900?

It is more hands-on. AI-900 only asked you to describe and identify things: its outline contains zero instances of create, build or implement. AI-901's outline contains fifteen. You are now expected to deploy a model in the Foundry portal, write system prompts, and build and test a single-agent solution.

How much does the AI-901 exam cost?

$99 USD in the United States, confirmed in Microsoft's own exam pricing feed. That is the standard fundamentals price and it is unchanged from AI-900. Price varies by the country or region in which the exam is proctored, and tax may be added.

Does the AI-901 certification expire?

No. Microsoft's renewal policy states that associate, expert and specialty certifications expire annually. Fundamentals certifications, including Azure AI Fundamentals, are not on that list and do not require an annual renewal assessment. Microsoft's exam page also lists AI-901's retirement date as none.

What score do you need to pass AI-901?

700 or greater on a scale of 1 to 1000. Microsoft notes that because this is a scaled score it may not equal 70 percent of the points. Microsoft publishes no question count and no pass rate for AI-901, so any exact figure you see quoted was invented.

AI-901 is the exam that replaced AI-900, and it is a different exam wearing the same certification name. AI-900 retired on June 30, 2026. You still earn Microsoft Certified: Azure AI Fundamentals, but the paper underneath changed completely. AI-900 had five domains; AI-901 has two, and 55 to 60 percent of it is a single product, Microsoft Foundry. The phrase "machine learning" appeared 13 times in AI-900's outline and appears zero times in AI-901's. It costs $99, needs 700 out of 1000, and does not expire. It is also no longer a describe-only exam: you are expected to deploy a model and build an agent.

Last updated July 2026

A fundamentals exam that now expects you to build an agent

AI-900 was famously a reading exam. Every one of its five domains literally began with the word "Describe." You could pass it without ever opening the Azure portal, and plenty of people did, in a weekend. AI-901 is not that exam. We counted the verbs in both official outlines, and the shift is not subtle.

Verb in the official skills outline	AI-900 (retired)	AI-901 (current)
Describe	29	9
Identify	32	10
Implement	0	6
Create	0	5
Build	0	4
Deploy	1	4

Zero instances of create, build or implement across the whole of AI-900. Fifteen across AI-901. The bullets now read "Create effective system and user prompts," "Deploy a model and interact with it in the Foundry portal," "Create a lightweight chat client application by using the Foundry SDK," and "Create and test a single-agent solution in the Foundry portal." That is a fundamentals exam asking you to ship a working agent.

The practical consequence: if your study plan is watching a video course and reading a glossary, which was genuinely enough for AI-900, it is no longer enough. You need portal time. And you need to be able to answer questions written about actions, not definitions, which is exactly the kind of question a generator can drill you on once you turn your own Foundry notes into practice questions.

AI-901 skills measured, straight from Microsoft's study guide

Two domains, current as of the April 15, 2026 update. One product carries the majority of the exam.

Domain	What is actually in it	Weight
Implement AI solutions by using Microsoft Foundry	Creating effective system and user prompts. Deploying a model and interacting with it in the Foundry portal. Building a lightweight chat client with the Foundry SDK. Creating and testing a single-agent solution. Text analysis and speech through Foundry Tools. Interpreting visual input with a multimodal model and generating images. Extracting information from documents, forms, images, audio and video using Azure Content Understanding. The majority of the exam.	55 to 60%
Identify AI concepts and capabilities	The six responsible AI principles: fairness, reliability and safety, privacy and security, inclusiveness, transparency, accountability. How generative AI models work, choosing a model by capability, and deployment configuration parameters. Identifying scenarios for common AI workloads, including generative and agentic AI, text analysis, speech, computer vision and information extraction.	40 to 45%

Two things stand out. First, agentic AI now appears on a fundamentals exam, which tells you how quickly Microsoft has moved agents from advanced material to baseline literacy. Second, responsible AI survived the rewrite intact, all six principles, and it sits in the larger conceptual domain. It is the most reliably examinable content on the paper because it does not change when a product gets renamed.

Microsoft does not publish a question count for AI-901, and publishes no pass rate for any exam. Its general guidance is that most exams "typically contain between 40-60 questions." AI-901 is not open book: the open-book policy applies to role-based exams, not fundamentals. The exam's listed retirement date is none.

Machine learning was on AI-900. It is not on AI-901.

This is the single biggest content change and the easiest one to verify. AI-900 had a whole domain called "Describe fundamental principles of machine learning on Azure," worth 15 to 20 percent of the exam. Regression, classification, clustering, training and validation datasets, Azure Machine Learning studio, Automated ML. The phrase "machine learning" appears 13 times in its outline.

Search AI-901's outline for the same phrase and you get zero hits. The domain is gone, and so is the word.

AI-900 domain (retired)	Weight	Where it went on AI-901
Describe AI workloads and considerations	15 to 20%	Survives inside "Identify AI concepts and capabilities," with responsible AI intact
Describe fundamental principles of machine learning on Azure	15 to 20%	Deleted. "Machine learning" appears 0 times in AI-901. It moved to AI-300.
Describe features of computer vision workloads on Azure	15 to 20%	Folded into the Foundry domain as a build task, not a description task
Describe features of NLP workloads on Azure	15 to 20%	Folded in as text analysis and speech through Foundry Tools
Describe features of generative AI workloads on Azure	20 to 25%	Expanded enormously. Now the spine of the exam, plus agents.

If you want the machine learning material, it did not vanish from Microsoft's certification ladder. It went up a level. The classical ML and MLOps content now lives on AI-300, the associate exam that replaced DP-100. What Microsoft decided is that a beginner in 2026 does not need to know what clustering is before they need to know what an agent is.

Practically, this is where most AI-901 candidates waste their time. They buy an AI-900 course, or a question bank scraped from one, and spend a fifth of their study hours on regression and Automated ML questions that cannot appear on the exam they booked.

How to build AI-901 practice questions from current material

Microsoft has not released a practice assessment for AI-901 yet, and the free question banks floating around are AI-900's.

1 Upload current material: Microsoft's Foundry documentation, the AI-901 study guide, or your own portal notes.
2 Skip machine learning: Regression, clustering and Automated ML are not on this exam. Do not let an old bank drill you on them.
3 Weight Foundry heavily: It is 55 to 60 percent of the paper. Prompts, model deployment, a chat client, a single agent, Content Understanding.
4 Drill responsible AI: All six principles survived the rewrite. It is the most stable, most examinable content on the exam.

The natural next step after AI-901 is AI-103, the associate exam for building AI apps and agents, which replaced AI-102. The machine learning material that AI-901 dropped now lives on AI-300. The other fundamentals exam, and the one that is not retiring, is covered by the AZ-900 practice test generator. If your route is administration rather than AI, start with AZ-104. Developers in the same retirement wave should compare AI-200 with the AZ-204 practice test generator. For any source document at all, use the certification exam generator.
