Your AI Doesn't Know the Difference Between Knowing and Guessing

I asked a local model what seven times eight was.

Not in chat. Through a tool-calling setup I wired myself, where the model reaches for tools on its own.

It reached for a tool called "Math." That tool does not exist. It made it up, answered with full confidence, and did the same thing again on a second machine running identical config.

In plain chat, the same model answered 56 without a problem.
