> Seriously though, why is it a model "card", safety "card"?

My assumption is because "card" has a more formal tone than a README, which is more like a quick "how to use the software" guide.

Collin's dictionary says about "cards":

> A card is a piece of stiff paper or thin cardboard on which something is written or printed. (1)

> A card is a piece of cardboard or plastic, or a small document, which shows information about you and which you carry with you, for example to prove your identity. (2)

> A card is a piece of thin cardboard carried by someone such as a business person in order to give to other people. A card shows the name, address, phone number, and other details of the person who carries it. (6)

Since companies spend a lot of resources training the model, and the model doesn't really change after release, I feel "card" is meant to give weight or heft to the discussion about the model.

It's not meant to be updated like a README or other software documents, it's meant to be handed out to others as a firm, unchanging "this is a summary of the model and its specifications", like a business card for models.
