Keep these terms with your own work
Archibal attaches these terms to every file your connected tools make, and keeps them in the delivery record as they stood when you delivered. Connect your tools before you generate: each generation lands in your library with its model, its prompt and the terms of the service you used. If the terms change later, your record still shows what they said when you shipped.
This page reproduces what the linked documents said on the dates shown. It is a record, not legal advice, and not a warranty of the providers' terms. Documents change; read the source before relying on it.
