eval — A repeatable test for AI quality — a set of tasks plus scoring — used the way software teams use test suites, because model output is too variable to judge by eyeballing.
sandbox — An isolated environment where AI-generated code or agent actions run without being able to touch anything real.
Why it matters
Running untrusted generated code is now routine, and this gives measured startup costs and a checked list of which isolation guarantees actually hold.
