Mic­ro­soft AI-901 (Azure AI Fun­da­men­tals)

No. Microsoft retired AI-900 on 30 June 2026 and replaced it with AI-901, which still awards the Microsoft Certified: Azure AI Fundamentals certification but is a different exam: two domains instead of five, more than half of the marks on building solutions in Microsoft Foundry, and an expectation of some Python and Azure familiarity. If you hold AI-900 your certification remains valid and does not expire.

Two domains, as of the 15 April 2026 skills measured: Identify AI concepts and capabilities (40–45%) — responsible AI, how generative models work, choosing and deploying models, and the text, speech, vision and information-extraction workloads; and Implement AI solutions by using Microsoft Foundry (55–60%) — prompts, deploying and calling models, building a chat client with the Foundry SDK, creating a single agent in the portal and a lightweight client for it, Azure Language and Azure Speech, multimodal and image-generation models, and Azure Content Understanding.

The pass score is 700 out of 1000. Microsoft's fundamentals exams give you 45 minutes of exam time (65 minutes of seat time) and typically contain 40 to 60 questions, though Microsoft says the number can vary. The UK price is £64.

Microsoft's audience profile says you need knowledge of Python coding syntax and programming techniques and familiarity with Azure resources, and its exam notes add that you should be familiar with REST APIs, SDKs and CLIs. The exam is still a fundamentals exam, but expect questions on which client, method, endpoint or parameter a lightweight application would use, not just concepts.

Microsoft Foundry is the unified platform (formerly Azure AI Foundry) for building, deploying and managing AI apps and agents on Azure: a Foundry resource holds projects, gives you a model catalog (Foundry Models), Foundry Tools such as Azure Language, Azure Speech, Azure Vision and Azure Content Understanding, Foundry Agent Service for prompt and hosted agents, and Foundry IQ for grounding agents in your own data.

Microsoft's entry-level AI certification (it replaced AI-900 in June 2026) for people starting out in AI solution development on Azure. Junior AI / software developer: Microsoft aims AI-901 at candidates at the beginning of a career in AI solution development who can work with Foundry SDKs and Azure resources. Machine learning engineer (entry route): Azure AI Fundamentals is Microsoft's starting point before the associate-level AI-103 (AI apps and agents) and AI-300 (MLOps engineer) exams. Data analyst moving into AI: The exam's concepts domain (responsible AI, models, text, speech, vision, extraction) is the AI literacy analysts are increasingly asked for.

AI-901 (Microsoft Azure AI Fundamentals) is Microsoft's entry-level AI certification and the replacement for AI-900, which Microsoft retired on 30 June 2026 — AI-900 can no longer be booked, and existing AI-900 holders keep a certification that does not expire. Verified against Microsoft Learn in September 2026: the AI-901 skills measured were updated on 15 April 2026 and sit in two domains — Identify AI concepts and capabilities (40–45%) and Implement AI solutions by using Microsoft Foundry (55–60%); the pass score is 700 out of 1000; Microsoft's fundamentals exams run 45 minutes (65-minute seat time) and typically carry 40 to 60 questions; the UK price is £64 through Pearson VUE, or Certiport for students and instructors. Unlike AI-900, AI-901 expects some Python and familiarity with Azure resources, REST APIs, SDKs and CLIs, and it uses Microsoft's current names — Microsoft Foundry (not Azure AI Foundry), Foundry Tools (not Azure AI services), Foundry resources and projects, Foundry Agent Service, Foundry IQ and Azure Content Understanding. PassNova's questions are written from the two official AI-901 learning paths and weighted to the two domains. Microsoft's free practice assessment now lives on AI Skills Navigator (sign-in required).
