What this teaches you
Doubting is protecting yourself
🤥 It makes things up without knowing
Remember Module 1: it predicts the likely word, not the true one. Sometimes the likely word is false — and it states it without blinking.
✅ Cross-check what matters
Numbers, dates, names, quotes, legal/medical advice: verify elsewhere. The AI is a great assistant, not a single source of truth.

2 quick questions
1. A hallucination is when the AI…
Right: it outputs a likely word that happens to be false, and presents it as true. That's why cross-checking matters.
2. What should you be most wary of?
Right: precise (and verifiable) details are the riskiest. Always cross-check them before relying on them.
What to remember
The AI can invent with confidence: the likely word isn't always true.
Be wary of precise details: numbers, dates, names, quotes.
Cross-check what matters elsewhere. Brilliant assistant ≠ single source of truth.
