Tell me about the time AI lied to you! I'm researching a mathematical way to stop these hallucinations

If you’ve spent any time with ChatGPT, you’ve probably been lied to. We’ve all been there. I have a particularly bitter memory. Last Christmas, the toy my kid wanted was sold out everywhere. I asked an AI to find a local shop that had it in stock. It confidently gave me a name and an address just 30 minutes away. I rushed there, full of hope. only to find it wasn't a toy at all. It was a restaurant. That experience pushed me to study why AIs lie.
