“ChatGPT was at 67%. Gemini was at 76%. Grok-3 was at 94%.” Jim Carter doesn’t waste time in this episode of The Prompt: if you’re treating AI answers like verified facts, you’re already in trouble.

Jim breaks down what “AI hallucination” really is in plain terms. The model isn’t checking a trusted database or “looking things up” the way people assume. It’s doing supercharged autocomplete—predicting the next word based on patterns from training data—and it can sound confidently right even when it’s completely wrong. From there, he maps the most common hallucination types.

Then he lands the real-world stakes. Companies are worried (77% say hallucinations are their top AI concern), and for good reason: in healthcare, law, and finance, one confident-sounding mistake can become real harm. Jim points to a law firm that was fined over $100,000 after submitting AI-written briefs loaded with fake citations.

The useful part is the fix-it toolkit. Jim walks through why hallucinations happen (training data gaps, stacked errors in long reasoning chains, and “prompt pressure” that punishes “I don’t know”). And he gives practical ways to reduce risk.

Key takeaways listeners can use today

1. Treat AI like a guesser, not a verifier
2. Stop prompts that force fake confidence; allow “I don’t know”
3. Use RAG and require quotes supporting each factual claim
4. Compare answers across tools when accuracy matters

Jim also shares two of his own prompts to help listeners reduce AI hallucinations immediately.
