What Should I Learn First
for AI Engineering?

The AI landscape is overwhelming. Hundreds of courses, frameworks, and tools.
Here's where to actually start in 2026.

Information Overload Is Keeping You Stuck.

YouTube, Twitter, and Reddit all recommend different starting points. You're paralyzed by conflicting advice.

Months spent on the 'wrong' topics while the field evolves. Time wasted learning things you didn't need.

Advanced courses assume prerequisites you don't have. Beginner courses teach what you already know.

A Clear Path Through the Noise.

The World-Class AI Engineer Cohort

Every AI career is different. The right starting point depends on your background, goals, and timeline. But there are proven foundations everyone needs, and a logical sequence to learn them.

Meet Your Mentor

Zen van Riel

My aim has been the same for years: become a world-class AI engineer. Every career move I've made has been measured against that.

I started as a software tester on a $500/month internship in the Netherlands. Taught myself to code, learned to ship real systems, and worked my way to Senior Engineer at GitHub.

Then I left GitHub. I joined an AI research lab as Member of Technical Staff, where I currently build products for secure AI monitoring.

The cohort draws directly from my real experience so you can make progress fast.

I run this special cohort with only a few people because hands-on work with me is what it takes to bring you to become a world-class AI engineer.

"The coaching played a huge part in my success. I focused on AI fundamentals, the certification path, and soft skills like professional writing. Having access to expert guidance gave me confidence during interviews and helped me feel I was on the right path.

I built my own platform (simple but functional) and deployed it on AWS. I used it in my portfolio and showcased it during interviews. The way complex topics were explained, especially the restaurant analogy for AI systems, really stuck with me. Focusing on doing the basics well was absolutely essential."

Frequently Asked Questions

I'm a complete beginner. Where do I actually start?

Start with Python programming. Not because it's the only language in AI, but because 90% of AI tutorials, libraries, and tools assume Python proficiency. You need to be comfortable writing functions, working with data structures, and debugging before touching any ML concepts. Give yourself 4-8 weeks of focused Python practice. Skip the math until you can code.

Should I learn Python or math first?

Python first, math later. Here's why: You can build working AI applications with libraries that handle the math for you. Understanding the math helps you debug and optimize, but it's not required to start. Most people who begin with linear algebra or calculus burn out before building anything. Get hands-on wins first, then backfill the theory as needed.

How long until I can build real AI applications?

With focused learning: 2-3 months to build basic AI applications using existing APIs and models. 4-6 months to understand enough ML to fine-tune models and make architectural decisions. 12+ months to do original research or build novel architectures. Most people overestimate what they'll learn in a month and underestimate what they'll learn in a year.

Should I learn traditional ML or jump straight to LLMs?

In 2026, start with LLMs and AI application development. The job market has shifted dramatically. Traditional ML (scikit-learn, classical algorithms) is still valuable for certain problems, but most entry-level AI engineering roles now involve building with foundation models. Learn prompt engineering, RAG patterns, and API integration first. Add traditional ML later if your role requires it.

Can I learn everything for free, or do I need paid courses?

You can learn the fundamentals for free. Python (Codecademy free tier, YouTube), LLM basics (documentation, free tutorials), and even build projects (free API credits). Paid resources become valuable when you need structure, accountability, or personalized feedback. The best investment isn't courses, it's having someone review your work and correct your mistakes early.

How is coaching different from self-study?

Self-study means figuring out what to learn, in what order, while avoiding dead ends. You'll waste weeks on the wrong things. Coaching gives you a personalized curriculum based on your background and goals, real-time feedback on your work, and accountability to actually finish. Most people can self-study, fewer actually do. Coaching compresses a 12-month journey into 4-6 months.

I've signed up for cohorts before and dropped out. How is this different?

It probably isn't, and you should hold the money. Most cohort dropouts are people who couldn't articulate what they were shipping when they signed up. That's why the consult exists, and why I turn down most applications. If we get on the call and you can't tell me what you'll have shipped at the end of week 8, I'll point you to the AI Native Engineer community until you can.

I'm not pivoting careers. I want to build a product. Does this still work?

Yes, the cohort works for people shipping their first serious AI system whether the goal is to land a senior role or to launch a product. The shipped system serves both equally well.

Do I need prior AI experience?

You need to be able to code in Python or TypeScript. Complete beginners can follow the classroom they get access to before the cohort sessions to come in well-prepared.

How much time will this take?

You'll spend 3 hours every Tuesday in the live session and roughly 3 hours of async work in between, for 8 weeks. The Tuesday session time is fixed.

What does it cost?

It's a four-figure investment that we discuss during the 30-minute consult, alongside whether the cohort is the right fit for your project.

Can I do this while working full-time?

Yes, most attendees do. The live session is one Tuesday a week and the async work fits around your existing schedule, as long as you can carve out roughly 6 hours a week.

I accept those who have the highest chance of success.

In the 30-minute call we discuss your goals and whether you are ready for the program.
