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 | $99 |
| Questions | 65 (50 scored + 15 unscored) | ~40–60 |
| Time | 90 minutes | 45–60 minutes |
| Passing score | 700 / 1000 | 700 / 1000 |
| Coding required | No | No |
| Prerequisites | None | None |
| Expires? | After 3 years | Never |
| Delivery | Pearson VUE or PSI | Pearson VUE |
| Heaviest content | Generative AI (52% across two domains) | Generative AI (20–25%), rest evenly split |
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 as its heaviest single domain (20–25%), but balances it against computer vision, NLP, and classic machine learning. If you want the most genAI per study hour, AWS wins.
2. Azure is the shorter, broader exam. AI-901 runs 45–60 minutes against AWS’s 90, and it surveys the whole AI landscape — vision, language, speech, ML fundamentals — at a gentler depth. If you want a rounded “what is all of this?” foundation, 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 the gentlest, broadest on-ramp → 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 fundamentals — supervised vs unsupervised learning, tokens, embeddings, RAG, responsible AI — overlap heavily, so the second exam costs maybe half the study time of the first. 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 45–60 minutes versus AWS's 65 questions in 90 minutes — and it surveys AI more broadly at a gentler depth. AWS goes deeper on generative AI. Both are foundational, no-coding 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 fundamentals overlap heavily — supervised vs unsupervised learning, tokens, embeddings, RAG, responsible AI — so the second exam typically costs about half the study time of the first, and both together run under $200.
Do these AI certifications require coding?
No. Both AIF-C01 and AI-901 are foundational exams with no coding and no prerequisites, designed for technical and non-technical candidates.
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.
