AWS AI Practitioner vs Azure AI Fundamentals: Which Should You Take First?
These are the two most popular entry-level AI certifications, and the decision between them is simpler than most comparison posts make it: match the cert to the cloud your workplace already uses. If your company runs on AWS, take the AWS AI Practitioner (AIF-C01). If it’s a Microsoft shop — Azure, Microsoft 365, Copilot everywhere — take Azure AI Fundamentals (AI-901). If it’s neither or you genuinely don’t know, AWS is the safe default because it’s the most widely used cloud.
That’s the answer. Here’s the evidence, plus the differences that actually matter.
Side by side
| AWS AI Practitioner (AIF-C01) | Azure AI Fundamentals (AI-901) | |
|---|---|---|
| Price | $100 USD | $99 USD |
| Questions | 65 (50 scored + 15 unscored) | Not published; expect roughly 40–60 |
| Time | 90 minutes | 45 minutes (65-minute seat) |
| Passing score | 700 of 100–1,000 | 700 |
| Coding expected | No | Python syntax and basics |
| Prerequisites | None | None |
| Expires? | After 3 years | Never |
| Delivery | Pearson VUE or online proctored | Pearson VUE or online proctored |
| Heaviest content | Generative AI: 52% across two domains | Implementing AI solutions in Microsoft Foundry: 55–60% |
What is actually on each exam
Both vendors publish the weightings, and they tell you where your study hours should go. AWS splits AIF-C01 into five domains:
- Fundamentals of AI and ML — 20%
- Fundamentals of Generative AI — 24%
- Applications of Foundation Models — 28%
- Guidelines for Responsible AI — 14%
- Security, Compliance, and Governance for AI Solutions — 14%
Microsoft splits AI-901 into two:
- Identify AI concepts and capabilities — 40–45%
- Implement AI solutions by using Microsoft Foundry — 55–60%
Read those two lists again, because they are the whole decision in miniature. More than half of the AWS exam is generative AI: foundation models, prompt engineering, retrieval-augmented generation versus fine-tuning, and Amazon Bedrock. More than half of the Microsoft exam is building something in Microsoft Foundry, which covers generative AI apps and agents, text and speech, computer vision and image generation, and information extraction.
Microsoft also updated the English version of AI-901 on 15 April 2026, so anything written for the old AI-900 is out of date. If you studied for AI-900 before it retired, see what changed in AI-901.
Which one is harder?
They are hard in different ways, and the honest answer depends on whether you write code.
AWS is broader but gentler. You get 90 minutes for 65 questions, which is about 83 seconds each, and AWS states no coding is required. The difficulty is breadth: a lot of AWS service names, and multi-answer questions that only count if you get every part right.
Microsoft is shorter but more technical. The exam runs 45 minutes inside a 65-minute seat, and Microsoft says candidates need “knowledge of Python coding syntax and programming techniques” and should be familiar with Azure resources. You do not have to write code in the exam, but questions assume you have seen some.
Both mark you against a scaled score with 700 to pass, and both are entry-level with no prerequisites. If you have never touched a cloud console, AWS is the kinder first exam. If you already script a little, AI-901 rewards that and takes less of your afternoon.
What each one really costs
The sticker prices are a dollar apart, so the difference is what happens afterwards. Azure AI Fundamentals is a one-time $99: Microsoft states plainly that “Fundamentals certifications do not expire.” The AWS AI Practitioner is $100 every three years, because AWS asks you to recertify by passing the current version before it lapses.
Over six years that is $99 against $300, before any retake. Neither number will change your life, but it is worth knowing before you pick. Full breakdowns, including retakes: AWS AI Practitioner exam cost and Azure AI Fundamentals exam cost.
The real differences
1. AWS goes deeper on generative AI. Over half of AIF-C01 is generative AI — foundation models, prompt engineering, RAG vs fine-tuning, Amazon Bedrock. AI-901 covers generative AI and agents too, but spreads its implementation domain (55–60%) across text and speech, computer vision and image generation, and information extraction as well. If you want the most genAI per study hour, AWS wins.
2. Azure is the shorter, more technical exam. AI-901 runs 45 minutes against AWS’s 90, but it expects basic Python and familiarity with Azure resources, and over half of it is about implementing AI solutions in Microsoft Foundry — generative AI apps and agents, text and speech, vision, and information extraction. If you want a foundation that includes building, not just vocabulary, Azure’s structure teaches it better.
3. Azure never expires; AWS lasts 3 years. Microsoft Fundamentals certs have no renewal, ever. AWS asks you to recertify every 3 years. Not a dealbreaker either way, but if “one and done” appeals to you, that’s a point for Azure.
4. The ecosystem is the tiebreaker that matters most. Certs pay off when they match the tools around you. Recruiters filtering for an AWS role search for AWS certs; a Microsoft-shop manager recognizes AI-901 instantly. The “better” cert is the one someone in your world will recognize.
Decision guide
- Your company uses AWS → AWS AI Practitioner. Done.
- Your company lives in Microsoft 365 / Azure / Copilot → Azure AI Fundamentals.
- You want maximum generative-AI depth → AWS.
- You want a beginner cert that gets you building (basic Python) → Azure.
- No cloud allegiance at all → AWS by default (biggest market share), or honestly: whichever one’s study guide you enjoy reading more. You’ll finish the one you enjoy.
Should you just do both?
It’s more reasonable than it sounds. The concepts — how generative AI models work, choosing a model, prompting, responsible AI — overlap, so the second exam goes faster than the first, though AI-901’s Foundry implementation work is new ground if you start with AWS. Plenty of people take one, realize the concepts transfer, and pick up the other within a couple of months for under $200 total. Start with the one that matches your workplace; treat the second as an optional victory lap.

Frequently asked questions
Which is easier: AWS AI Practitioner or Azure AI Fundamentals?
Azure AI Fundamentals (AI-901) is the shorter exam — roughly 40–60 questions in 45 minutes versus AWS's 65 questions in 90 minutes — but it is more technical: Microsoft expects basic Python and familiarity with Azure resources, and over half the exam covers implementing AI solutions in Microsoft Foundry. AWS goes deeper on generative AI concepts. Both are foundational exams with a 700/1000 passing score.
Should I get an AWS or Azure AI certification first?
Match the cert to the cloud your workplace uses: AWS shops should take the AWS AI Practitioner, Microsoft shops should take Azure AI Fundamentals. If neither applies, AWS is the safe default as the most widely used cloud.
Can I take both AWS AI Practitioner and Azure AI Fundamentals?
Yes, and it is more reasonable than it sounds. The concepts overlap — how generative AI models work, choosing a model, prompting, and responsible AI — so the second exam goes faster, though AI-901's Microsoft Foundry implementation work is new ground if you start with AWS. Both together run under $200.
Do these AI certifications require coding?
AIF-C01 does not. AI-901 has no formal prerequisites, but Microsoft expects knowledge of Python coding syntax and programming techniques plus familiarity with Azure resources, because over half the exam covers implementing AI solutions in Microsoft Foundry.
Which AI certification expires — AWS or Azure?
The AWS AI Practitioner is valid for 3 years, then you recertify. Azure AI Fundamentals never expires — Microsoft Fundamentals certifications have no renewal requirement.
