Open courseHow GACS AI learning courses work
- 1Get oriented — pick your path
If you're new to LLMs, start with LLM Engineering. If you can already call an LLM API and want to build autonomous systems, start with AI Agents Mastery. Both are free end-to-end.
- 2Learn the foundations
Each diploma ships with a structured study book, lessons, drills, and module reviews. You read, you build, you test — no passive video binge.
- 3Ship a real capstone
Every diploma ends in a real project: deploy it, document it, and submit it to the AI Pre-Flight Coach for instant rubric feedback before reviewers see it.
- 4Get verified and shown off
Approved capstones go on the public Verified Capstone Showcase with a permanent share link — proof recruiters can click, not a PDF in a drawer.
Verifiable
Every certificate has a unique ID and a public verification page.
Portfolio first
Capstone showcase makes your work findable by recruiters.
Free to certify
No paywall to take the exam or earn the certificate.
AI learning courses — common questions
Are these AI learning courses really free?
Yes — the diploma core (modules, study books, exam, capstone, and printable certificate) is free. The only paid option is a mentored cohort for students who want live review and accountability.
Where should an absolute beginner start?
Start with the LLM Engineering diploma — it assumes Python comfort but teaches the rest from first principles. Once you can build a small RAG system end-to-end, move into AI Agents Mastery.
How long does each course take?
Each diploma is roughly 40 hours of focused work. Most students finish in 4–8 weeks part-time. There's no expiry — you can take longer.
Is the certificate worth anything to employers?
Every certificate carries a unique ID and a public verification page (gacs.app/verify-certificate). Recruiters and clients can confirm it instantly. Pair it with your Verified Capstone — that's what actually moves hiring conversations forward.
Do you offer paid AI learning courses too?
Yes — the same diplomas have an optional paid mentored cohort with live reviews, office hours, and a smaller group. The free track is identical in content and gives you the same certificate.
What's the AI Pre-Flight Coach?
Before you submit your capstone, the AI Pre-Flight Coach scores your draft against the official diploma rubric, flags gaps, and tells you what to fix. It's there so you don't get bounced on issues you could have caught yourself.
