Should I Learn Claude or
OpenAI First?
The real answer isn't what you expect. Here's how to make
a decision that accelerates your AI engineering career.
You're Asking the Wrong Question.
The AI landscape shifts constantly. What's popular today might be displaced tomorrow.
Learning one API deeply often means relearning everything when you switch platforms.
Job postings mention both. You don't know which skill set employers actually value more.

The World-Class AI Engineer Cohort
The developers who thrive in AI aren't locked to one platform. They understand prompt engineering, context management, and system design patterns that transfer across any model. Here's how to build that foundation.
Master Core Concepts
Prompting, context windows, tool use
Build With Both
Quick projects on each platform
Specialize Strategically
Based on your target industry
Meet Your Mentor
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
Which should I actually learn first - Claude or OpenAI?
Start with whichever has better documentation for your use case. In 2026, both platforms are mature and well-documented. OpenAI has broader ecosystem integration and more tutorials available. Claude excels at longer context windows and nuanced instruction following. But here's the truth: spending 2 weeks with each platform teaches you more than 2 months with just one. The concepts transfer directly.
Which is more marketable - Claude or OpenAI experience?
OpenAI currently appears in more job postings due to first-mover advantage. However, Anthropic (Claude) is growing rapidly in enterprise. The smartest move? List both on your resume. Most production systems in 2026 use multiple models anyway. Employers value developers who can evaluate and switch between providers based on requirements.
Is one easier to learn than the other?
Both have similar learning curves for basics. OpenAI's API has more legacy patterns to navigate due to its longer history. Claude's API is cleaner but has fewer community resources. The real learning curve is understanding prompt engineering, token economics, and when to use AI vs traditional code - these skills transfer 100% between platforms.
How hard is it to switch between Claude and OpenAI?
Surprisingly easy if you learned the right way. The API calls are slightly different, but the core patterns are identical. Developers who learned principles first can switch in a day. Those who memorized one API's quirks struggle more. This is exactly why coaching focuses on transferable skills.
Do I need to know both to get hired?
Not always, but it helps significantly. Many teams use OpenAI for some tasks and Claude for others. Knowing both signals that you understand the landscape and can make informed decisions. It also protects your career - if one platform has issues or changes pricing, you're not stuck.
How does coaching help with this decision?
Coaching gives you a personalized learning path based on your goals. Instead of guessing which platform matters for your target role, you get guidance from someone who's placed developers at companies using both. We focus on the 20% of knowledge that covers 80% of use cases, so you're productive fast on any platform.
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.
