Chapter 12Where do my words go?
Whose agreement is it?
It depends less on which model you use than on the arrangement around it: what kind of account, whose agreement, which features are on, and whose computer runs it.
The same model can sit inside very different arrangements. Four come up most.
Personal account
You sign up yourself, free or paid. The agreement is between you and the vendor. Vendors commonly give personal users a setting for whether their chats help train future models; Anthropic calls it "Model Improvement," and OpenAI's is "Improve the model for everyone."12 A paid personal plan is still a personal agreement.3
Organization account
Your employer or school signs the agreement with the vendor. Anthropic and OpenAI both say business data isn't used for training by default.456 Organization plans can add administrator controls such as single sign-on, audit logs, retention settings and role-based permissions, depending on the plan.7896
An introduction to the ideas, not legal advice and not the reference for any product's current terms. Vendors change their plans and features often; your organization's privacy and compliance office, your signed agreements and each vendor's current documentation decide what is allowed.
