Can scientists build a lie detector for AI chatbots?

Ask an AI chatbot for some medical advice and it might recommend you head to the hospital when all you really have is indigestion. One of the biggest issues with AI chatbots today is that they can still share false information, ...

The tests that grade AI may be getting it wrong

Before a new AI model reaches the public, its developers run it through a battery of tests known as "benchmarks," which score it on everything from reasoning ability to how safe it is for people to use. Billions of investment ...
