lab

Definition

Short for laboratory: either a research group — an academic lab, or a corporate research organization, as in the phrase frontier labs used for the handful of companies training the largest models — or an interactive sandbox where a reader can run and perturb an example. The organizational sense answers who built this; the environment sense names a place to try it. Context, and whether it is capitalized as part of a name, separates them.
