Master AI Verification. Stop Hallucinations.
A free, comprehensive course on deterministic AI verification — learn to mathematically prove that LLM outputs are correct before they reach production.
Built on QWED's philosophy: "Safe AI is the only AI that scales." No GPU required. No cost. Just knowledge.
The Core Idea: Artist vs. Accountant
This course teaches you to pair creative AI with deterministic verification — because you wouldn't let an artist do your taxes.
LLMs are Artists
- Creative and convincing
- Great at brainstorming
- Bad at precise details
- An artist is the wrong hire for your taxes
QWED is the Accountant
- Boring and strict
- Terrible at creativity
- Never makes a math mistake
- This is who handles your money!
Developers Ship LLM Apps Without Verification
Most AI applications today go to production with nothing between the model and the user but prompt engineering and hope. When a financial chatbot miscalculates interest, or a medical assistant suggests the wrong dosage, there's no safety net.
RAG gives context but can't catch reasoning errors. Guardrails prevent harmful content but can't verify math. Fine-tuning improves probabilities but can never reach 100% accuracy.
After this course, you'll be able to:
- Understand determinism vs probabilistic systems
- Implement formal verification in production
- Use mathematical proofs to catch hallucinations
- Ship provably correct AI outputs
Safety ≠ Correctness

What You'll Build
This isn't just theory — you'll ship real, production-ready systems.
Quick Check
Why can't RAG alone prevent hallucinations?
RAG provides context, but can't solve reasoning errors. If a document says "Revenue is $5M" and the LLM calculates "Profit = $5M - $6M = $1M", RAG can't catch that math error. Verification checks the logic deterministically.
Frequently Asked Questions
Do I need a GPU?
No! Run everything locally with Ollama (free, CPU only) or use the OpenAI API for pennies. No expensive hardware required.
How long is the full course?
Fast track: 3-4 hours. Full course with videos: 8-10 hours. With hands-on capstone: 12-15 hours. Go at your own pace over 2-3 weeks.
Is this really free?
100% free and open source under CC0-1.0 (public domain). Part of QWED's mission to make AI verification accessible to everyone.
What will I build?
A verified banking agent, CI/CD pipelines that block hallucinations, and cryptographic audit trails — real portfolio pieces.
