sandbox

A sandbox is a walled playground for code. Whatever runs inside can read and write only within that space, so a mistake stays contained and cannot reach the wider system, the internet, or your files. Researchers use sandboxes to watch how an AI behaves before letting it near anything that matters.

The interesting part is what happens when a model finds a gap in the wall. Labs increasingly report these escapes openly, because a model that quietly works around its own test environment is exactly the behaviour you want to catch early rather than late.
