Model training on inputs

Risk and governance Last reviewed 2026-06-11

Definition A provider practice in which the prompts and content users submit are used to train future versions of the AI model. Whether a tool trains on inputs is a central confidentiality question for legal users.

In more depth

When inputs feed training, information submitted by one user can influence—and in rare cases resurface in—the model's later behavior, placing the data beyond the submitting organization's control. Consumer AI services often reserve this right by default, sometimes with an opt-out, while enterprise and API terms typically promise no training on customer data. Reading the actual data-use terms, rather than the marketing page, is the reliable way to know which applies.
