IPA FE Subject A 2025 Question 17

When a user does not want what they enter to be used to train the generative AI — opting out refuses a use of the data that the service would otherwise make.

Opt-out means the data is used unless the person declines; opt-in means it is used only after the person agrees. Many generative AI services may use the prompts and files that users enter as training data for their models unless told otherwise. What a model has learned can surface in its answers to other users, so entering confidential or personal information becomes a leak risk. Setting the opt-out (turning off use for training) tells the service not to use that user's input for training.

Answer (b)

Why not others:

• •(a) — opting out does not create or assert a copyright; whether generated output is protected is a question of copyright law, not of a service setting
• •(c) — wanting one's input passed on to other users through the AI is the opposite of what opting out of training achieves
• •(d) — the credibility of generated answers is improved by checking them against reliable sources, not by withholding one's input from training

Key rule: Opt-out: used unless you refuse; opt-in: used only after you agree. In a generative AI service the opt-out setting keeps what you enter out of model training.
