AI Hallucinations

AI hallucinations aren't just annoying, they're a legal and business liability.

A lawyer was fined $5,000 for submitting six fabricated case citations generated by ChatGPT.

Air Canada was ordered to pay a customer after its chatbot invented a discount policy that never existed.

Google's AI Overviews told users to put glue on pizza.

And employees spend 4.5 hours per week just correcting AI mistakes.

These aren't edge cases anymore. There are 979 documented hallucination cases across 31 countries.

The EU AI Act is rolling out enforcement. 42 U.S. state attorneys general have warned major AI companies to fix this or face legal action.

"The AI said so" is no longer an excuse, it's becoming a liability.

So how do you actually prevent hallucinations?

At Gurubase, we built a multi-layer defense system:

• Source grounding: answers come only from your verified knowledge base
• Multi-query vector search to catch relevant context despite wording differences
• LLM-based evaluation scoring context relevance on a 0-1 scale
• Trust scores visible to users (green, yellow, red)
• Source attribution with direct links to original documents
• And when the system isn't confident? It says "I don't know" instead of making things up

The full breakdown with real-world examples, regulatory details, and technical architecture is in our latest blog post.
