If you are planning to start your Microsoft AI certification journey in 2026, you have probably already noticed that something has changed. The exam that most beginners were told to take first — Microsoft Azure AI Fundamentals (AI-900) — is now scheduled to retire on June 30, 2026. And its replacement, AI-901, is rolling out at almost exactly the same time.
That creates a real decision problem for anyone who is just getting started or who is mid-preparation right now.
Should you rush to finish AI-900 before it retires? Should you wait for AI-901? Is one harder than the other? Does it even matter which fundamentals exam you take if you are planning to move on to associate-level certifications anyway?
This guide answers all of those questions in plain language. We will cover what each exam actually tests, who each one is designed for, how the timing works, and which one makes the most sense depending on your specific situation. By the end you will have a clear answer — not a vague “it depends” — based on your actual goals and timeline.
The Short Answer First
Take AI-900 if you can realistically prepare and sit the exam before June 30, 2026, and you want a lifetime-valid credential on your transcript right now.
Take AI-901 if you are starting from scratch in mid-2026 or later, you want a credential that reflects Microsoft’s current AI direction, and you are not in a rush to certify immediately.
The most important thing to understand: AI-900 has lifetime validity. If you earn it before retirement, it never expires. That makes it genuinely worth pursuing even with a June 30, 2026 deadline — as long as you can actually prepare and test in time.
That is the short answer. The full answer depends on your role, your timeline, and where you want your certification journey to go next.
What Is AI-900 and What Does It Actually Test
AI-900 is the Microsoft Azure AI Fundamentals certification. It has been one of the most popular Microsoft fundamentals exams since its launch, attracting candidates from virtually every background — developers, business analysts, project managers, students, career changers, and IT professionals who want a foundational understanding of artificial intelligence concepts on Azure.
The reason AI-900 became so popular is its accessibility. You do not need coding experience to pass it. You do not need a deep technical background. It is designed to validate that you understand what AI is, how it works conceptually, what Azure AI services exist, and how responsible AI principles apply to real-world solutions.
The official skills measured in AI-900 include:
Describe AI workloads and considerations
This covers common AI workload types such as machine learning, computer vision, natural language processing, document intelligence, and knowledge mining. It also covers responsible AI principles including fairness, reliability, privacy, inclusiveness, transparency, and accountability.
Describe fundamental principles of machine learning on Azure
This includes core machine learning concepts, types of machine learning, core machine learning concepts in Azure Machine Learning, and how Azure Machine Learning enables data scientists and developers to build and manage models.
Describe features of computer vision workloads on Azure
This covers image classification, object detection, optical character recognition, facial analysis, and the Azure services that support computer vision solutions including Azure AI Vision and Azure AI Face.
Describe features of natural language processing workloads on Azure
This includes text analysis, named entity recognition, language detection, sentiment analysis, speech recognition, translation, and the Azure services that support NLP solutions.
Describe features of generative AI workloads on Azure
This is a newer addition to the AI-900 scope and covers large language models, the concept of tokens and embeddings, Azure OpenAI Service, prompts, and responsible generative AI principles.
The exam duration is typically around 45 minutes, the passing score is 700 out of 1000, and it is widely considered one of the more approachable Microsoft exams available. Most candidates report that 20 to 40 hours of focused study is sufficient preparation for AI-900 if you are starting from zero.
What Is AI-901 and What Will It Actually Test
AI-901 is the updated version of the Azure AI Fundamentals certification. Microsoft has positioned it as the modern replacement for AI-900, reflecting the shift in how AI is being built and used on Azure as of 2026.
While the full official exam blueprint for AI-901 is still being finalized as of early 2026, Microsoft’s Skills Hub and certification announcements give a clear picture of the direction.
AI-901 is described as covering building basic AI apps and agents on Microsoft platforms. That language is meaningfully different from AI-900’s framing around AI concepts and Azure AI services. Where AI-900 emphasizes understanding and recognition, AI-901 appears to emphasize practical application — building things, not just recognizing what they are.
Based on Microsoft’s published direction, AI-901 is expected to cover:
Core AI and generative AI concepts
Similar to AI-900’s foundational coverage but updated to reflect 2026 AI capabilities including more emphasis on generative AI, large language models, and AI agents as mainstream concepts rather than emerging ones.
Microsoft Foundry basics
AI-901 is expected to introduce Microsoft Foundry — Microsoft’s unified platform for building AI applications — at a conceptual level appropriate for a fundamentals exam.
AI agents and agentic concepts
Where AI-900 barely touched on agents, AI-901 is expected to cover what AI agents are, how they work, and how they fit into Microsoft’s AI application stack. This reflects the reality that agentic AI is no longer an advanced niche concept — it is part of the mainstream AI conversation in 2026.
Building simple AI applications on Azure
AI-901 appears more oriented toward candidates who want to understand not just what AI services exist but how they are combined into functional applications. This shifts the fundamentals bar from recognition to basic application understanding.
Responsible AI in the generative AI era
Responsible AI principles remain core to any Microsoft AI fundamentals credential, but AI-901 is expected to extend this into generative AI and agent-specific responsible AI considerations.
The beta exam for AI-901 is expected in April 2026 with general availability in June 2026. Prep materials, practice assessments, and learning paths will build out over time as the exam matures.
AI-900 vs AI-901: Key Differences at a Glance
| Area | AI-900 | AI-901 |
| Current status | Active, retires June 30, 2026 | Launching April–June 2026 |

Who Should Take AI-900 in 2026
AI-900 still makes strong sense for specific groups of people in 2026. Here is who those people are.
Candidates who are already prepared or nearly prepared
If you have already completed the Microsoft Learn AI-900 learning path, bought practice exams, and done your lab work, switching directions now would waste your preparation investment. The smart move is to schedule your exam immediately and test before June 30, 2026. A completed AI-900 certification with lifetime validity is worth more than an incomplete transition to AI-901.
Professionals who need a credential on their transcript quickly
If you are updating your LinkedIn profile, applying for jobs, or trying to demonstrate AI awareness to your employer before a specific deadline, AI-900 is available right now with a mature prep ecosystem. AI-901 will not be in general availability until June 2026 at the earliest, and beta exams can feel less settled for candidates who want predictability.
Business users and non-technical professionals
AI-900 was specifically designed to be accessible to people without coding or engineering backgrounds. Business analysts, project managers, consultants, sales professionals, and organizational leaders who want to demonstrate AI literacy will find AI-900 achievable with moderate study effort. AI-901 appears more application-oriented which may be less relevant for purely business-focused candidates.
Students and career starters who can test before the deadline
If you are a student or early-career professional who wants an AI credential quickly and can realistically sit the exam before June 30, 2026, AI-900 gives you a lifetime-valid Microsoft credential that remains permanently on your transcript. That is a meaningful career asset even as the certification landscape evolves.
Who Should Take AI-901 in 2026
For many candidates starting fresh in 2026, AI-901 will be the more logical choice. Here is who fits that profile best.
Candidates starting from zero in mid-2026 or later
If you are reading this after April or May 2026 and have not yet started studying, the timeline for AI-900 preparation and testing is extremely tight. Rather than rushing through a fundamentals exam under time pressure, starting on AI-901 when it becomes available gives you a cleaner path with more time to prepare properly.
Developers and technical professionals building AI applications
AI-901 appears specifically designed for candidates who want to understand not just AI concepts but how AI applications and agents are built on Azure and Microsoft Foundry. If your work involves building things with AI rather than simply working alongside AI tools, AI-901’s application-centric framing is more relevant to your reality.
Candidates planning to pursue AI-103 or other new AI certifications
If your certification roadmap includes AI-103 (Azure AI App and Agent Developer Associate) or other new 2026 Microsoft AI credentials, starting with AI-901 makes natural sense. The fundamentals concepts covered in AI-901 will align more closely with the associate-level exams Microsoft is building around the same architectural direction.
Professionals who want the most future-relevant credential
AI-901 is what Microsoft is building its AI certification on-ramp around going forward. If you are making a long-term career investment in Microsoft AI technologies, starting on the path Microsoft is actively developing and supporting is generally smarter than starting on a path that is already scheduled for retirement.
The Lifetime Validity Question: Does It Really Matter
One of the most important things about AI-900 that many candidates overlook is its lifetime validity. Unlike role-based Microsoft certifications which expire after one year and require annual renewal, fundamentals certifications do not expire. Once you earn AI-900, it stays on your transcript permanently.
This makes the retirement timeline less scary than it first appears. You are not racing against a certification that will disappear from your profile. You are racing against a window to earn it for the first time.
If you earn AI-900 before June 30, 2026, you have a permanent Microsoft AI credential on your transcript for the rest of your career. That credential does not become less valid because AI-901 launched. It simply becomes the older version of the fundamentals path — similar to how other technology certifications age but retain their historical value as proof of knowledge at a point in time.
AI-901 will almost certainly also carry lifetime validity as a fundamentals certification, following Microsoft’s consistent pattern. So the validity question does not ultimately favor one exam over the other. What matters more is which one you can actually earn given your timeline and preparation level.
How Hard Is AI-900 Compared to AI-901
For AI-900, the difficulty picture is very clear. The exam is widely regarded as one of the most approachable in Microsoft’s entire portfolio. Most candidates with moderate study effort pass on their first attempt. The content is conceptual rather than deeply technical, multiple choice questions dominate the format, and the official Microsoft Learn learning path covers everything you need.
For AI-901, making a definitive difficulty comparison is not yet possible since the exam is still in beta as of early 2026. However, based on the direction of the content — more application-focused, more agent-aware, more Foundry-oriented — it is reasonable to expect that AI-901 will be slightly more practical in its orientation than AI-900.
That does not necessarily mean harder. It means the questions may lean more toward understanding how things work together rather than purely recognizing what individual concepts mean. For candidates who learn by doing rather than by reading, AI-901’s more applied framing may actually feel more intuitive.
The safe assumption for now is that both exams sit at a similar difficulty level appropriate for a fundamentals certification. Neither requires hands-on lab experience to pass, and neither assumes prior technical certification history.
Preparation Strategy for AI-900
If you are targeting AI-900 before the June 30, 2026 retirement deadline, here is how to prepare efficiently.
Start with the official Microsoft Learn path
Microsoft’s free AI-900 learning path on Microsoft Learn covers all exam objectives in a structured sequence. It includes reading modules, knowledge checks, and sandbox exercises. This should be your primary study foundation.
Use the official practice assessment
Microsoft offers a free practice assessment for AI-900 on the exam page. This is one of the best free resources available and directly reflects the style and format of real exam questions. Complete it multiple times until you are consistently scoring above 80 percent.
Study responsible AI principles carefully
Many candidates underestimate the responsible AI section. Microsoft takes its responsible AI framework seriously and questions in this area tend to require more nuanced understanding than simple memorization. Know the six principles — fairness, reliability and safety, privacy and security, inclusiveness, transparency, and accountability — and be able to apply them to scenario-based questions.
Cover generative AI content thoroughly
The AI-900 study guide has been updated to include generative AI concepts. Do not skip this section assuming it is too new to appear heavily on the exam. It is a growing part of the assessed content.
Practice with quality exam preparation materials
Alongside Microsoft Learn, using high-quality practice questions helps you get comfortable with the question format and identify gaps in your knowledge before exam day. Our AI-900 exam preparation materials are designed to help you validate your readiness before you sit the real exam.
A realistic study timeline for AI-900 starting from zero is 2 to 4 weeks of consistent daily study for non-technical candidates, and 1 to 2 weeks for candidates with some prior cloud or AI exposure.
Preparation Strategy for AI-901
Since AI-901 is still in beta as of early 2026, the prep ecosystem is thinner than AI-900’s. Here is how to approach it.
Follow Microsoft’s official AI-901 course when available
Microsoft typically publishes an official learning path and course aligned to each new certification. When AI-901 materials become available on Microsoft Learn, start there before looking at third-party resources.
Understand Microsoft Foundry at a conceptual level
AI-901 is expected to include Foundry concepts. Spend time with Microsoft’s official Foundry documentation and overview materials to build familiarity with the platform before diving into exam-specific prep.
Learn what AI agents are and how they work
Agent-related content appears to be a meaningful part of AI-901’s scope. Understanding what agents are, how they use tools and knowledge connections, and how they fit into Microsoft’s AI application stack will help you across both this exam and any associate-level certifications you pursue afterward.
Be patient with the prep ecosystem
New exam prep content takes time to mature. Community feedback, practice questions, and unofficial study guides for AI-901 will improve significantly in the months after general availability. If you are taking AI-901 in the beta window, expect some uncertainty and focus heavily on official Microsoft materials.
AI-900 and AI-901 as Stepping Stones: Where They Lead
Understanding where each fundamentals exam leads helps you choose the right one for your broader certification roadmap.
AI-900 → Traditional Azure AI path (now retiring)
AI-900 was designed as the entry point to the AI-102 Azure AI Engineer Associate path. Since AI-102 is also retiring on June 30, 2026, the AI-900 to AI-102 pathway is closing simultaneously.
AI-901 → New AI certification paths
AI-901 is being designed as the entry point to Microsoft’s new AI certification stack including AI-103 (Azure AI App and Agent Developer Associate) and potentially other new 2026 AI credentials. If you are planning a multi-certification AI journey on Microsoft’s newer path, AI-901 is the more logical starting point.
If you are specifically deciding between AI-900 and AI-102 as a pair, we have also covered that comparison in our AI-900 vs AI-102 guide. And if your next step after fundamentals is the associate level, our AI-102 vs AI-103 comparison explains the full picture of what is changing at that level.
For the broader context of all certifications retiring this year, our complete guide to Microsoft certifications retiring in 2026 covers every exam and replacement in one place.
Common Mistakes to Avoid
Mistake 1: Assuming AI-900 is no longer worth taking
Some candidates read about the retirement and immediately assume AI-900 is already irrelevant. It is not. It is a fully active, respected certification with lifetime validity that you can still earn right now. The retirement date means you cannot earn it after June 30, 2026 — not that it has no value today.
Mistake 2: Waiting too long and missing the AI-900 window
The opposite mistake is equally common. Candidates who intend to take AI-900 keep delaying their exam date and suddenly find themselves in June with no time to prepare. If you want AI-900, schedule your exam date now and work backward from it.
Mistake 3: Treating fundamentals certifications as optional stepping stones
Both AI-900 and AI-901 are standalone credentials with real career value, not just checkboxes before the associate level. Employers in non-technical roles — consulting, sales, project management, business analysis — genuinely value Microsoft AI fundamentals credentials as proof of AI literacy.
Mistake 4: Assuming AI-901 will be available immediately
AI-901 is in beta from approximately April 2026 with general availability in June 2026. If you are planning to take AI-901 in early 2026, you will need to wait for the beta window to open. Do not plan your certification timeline around AI-901 being available right now.
Mistake 5: Skipping fundamentals entirely to go straight to associate level
Some technical candidates assume they can skip the fundamentals exam and go straight to AI-102 or AI-103. While Microsoft does not require fundamentals as a prerequisite, the foundational concepts covered in AI-900 and AI-901 genuinely help you understand associate-level content faster. Skipping fundamentals is a valid choice but not always the time-saver it appears to be.
Final Verdict: AI-900 or AI-901 in 2026
The right answer comes down to your timeline and your goals.
Choose AI-900 if:
- You are already partially prepared and can test before June 30, 2026
- You want a lifetime-valid AI credential on your transcript as soon as possible
- You are a non-technical professional focused on AI literacy rather than AI development
- You plan to follow the existing AI-102 path before it retires
Choose AI-901 if:
- You are starting fresh and cannot realistically prepare and test before June 30, 2026
- You want to align with Microsoft’s new AI direction from the beginning
- You are a developer or technical professional planning to pursue AI-103 or other new AI credentials
- You want to build on a foundation that Microsoft is actively investing in for the next several years
If you genuinely cannot decide: Ask yourself one question. Can you realistically prepare and sit AI-900 before June 30, 2026? If yes, do it. If no, start building toward AI-901 when it becomes available.
The fundamentals certification you earn matters less than actually earning one and continuing your learning journey from there.
FAQs
Is AI-900 retiring in 2026?
Yes. Microsoft has confirmed that the Azure AI Fundamentals certification and its associated AI-900 exam will retire on June 30, 2026. After that date you will not be able to take the exam or earn the certification for the first time.
Does AI-900 expire after you earn it?
No. AI-900 is a fundamentals certification with lifetime validity. Once you earn it before the retirement date it stays on your Microsoft Learn transcript permanently and never requires renewal.
When will AI-901 be available?
Based on Microsoft’s official announcements, AI-901 beta is expected in April 2026 and general availability is expected in June 2026. Training materials are expected to become available in March 2026.
Is AI-901 harder than AI-900?
The full exam blueprint for AI-901 is not yet published so a definitive comparison is not possible. Based on Microsoft’s announced direction, AI-901 appears more application and agent-focused than AI-900 but should remain at a fundamentals difficulty level appropriate for candidates without deep technical backgrounds.
Will AI-900 still count toward Microsoft partner skilling points after retirement?
For partners who earned MS-900 before retirement, Microsoft confirmed it continues to count toward skilling points for a period after retirement. A similar arrangement may apply to AI-900 but candidates should verify directly with Microsoft partner documentation as specifics may vary.
Can I use AI-900 as a stepping stone to AI-103?
Technically yes, since Microsoft does not enforce prerequisites between fundamentals and associate certifications. However, AI-901 is designed to align more directly with the AI-103 learning path, so new candidates planning to pursue AI-103 will likely find AI-901 a more natural foundation.
Should I take both AI-900 and AI-901?
For most candidates this is unnecessary. If you earn AI-900 before retirement you have a permanent credential and can proceed to associate-level certifications. Taking AI-901 afterward would give you a second fundamentals credential covering similar ground. Unless you have a specific reason — such as wanting to demonstrate familiarity with the newest Microsoft AI stack — taking both is generally not the best use of your study time.
Where can I find AI-900 study materials right now?
Microsoft Learn has a complete free learning path for AI-900 including modules, knowledge checks, and a free practice assessment. You can also use our AI-900 exam preparation materials to test your readiness with practice questions before exam day.
