Should you take it?

  • Suits developers starting out with AI on Azure who want an entry exam that does not expire.
  • Not for complete beginners to code: despite the fundamentals name, Microsoft expects Python syntax and familiarity with Azure resources.
  • The catch: 55 to 60% of the exam is building AI solutions in Microsoft Foundry, so reading about AI won't get you through.
  • Take AB-900 instead if you run Microsoft 365 rather than build on Azure; it covers Copilot and agent administration and also doesn't expire.

Is the AI-900 exam still available?

No. Microsoft retired AI-900 on June 30, 2026 and replaced it with AI-901. The certification keeps its name, Azure AI Fundamentals, so a course or answer that still says AI-900 is out of date.

Microsoft Certified: Azure AI Fundamentals (AI-900) (retired)

Should you take it?

  • Suits you only if you already passed AI-900 and want to show an employer it covered vision, language and generative AI on Azure.
  • Not for anyone planning to sit it now: Microsoft retired the AI-900 exam on June 30, 2026.
  • The catch: AI-901 puts 55 to 60% on building in Microsoft Foundry, which AI-900 never tested, so your pass looks dated.
  • Take AI-901, Microsoft's stated replacement, for Azure AI fundamentals today; it doesn't expire but expects Python coding syntax.

What does AI-901 expect you to know?

More coding than the name suggests. Microsoft expects Python syntax, a working idea of AI solutions in Azure and familiarity with Azure resources. If you don't code, a non-technical exam such as Generative AI Leader is a better fit.

Which entry-level AI exams could you take instead?

If you work on AWS, AWS Certified AI Practitioner (AIF-C01) costs $100; AUD 150. If you use Google Cloud or don't code, Generative AI Leader costs $99 plus tax.

How we chose

  • How to prepare: courses that name this certification, as each provider describes them, Microsoft's own first.
  • Alternatives: certifications in the same family or on the same topic, at the same level, leaving out partner-only and invite-only ones; a replacement the issuer names comes first.
