As OpenAI continues to develop frontier models, we work hard to help ensure that our model training process respects privacy. We’ve developed state of the art technologies to help our models learn useful general patterns rather than private information about individuals, and we have a number of user controls and policies to help keep individuals in control of their data.

This post explains what information may be used in model training, how we reduce the processing of personal information in that process, and how users can control whether their ChatGPT conversations help improve our models.

To develop the models that power ChatGPT⁠(opens in a new window), we use a mix of information sources, including publicly available information, information we access through partnerships, and information provided or generated by users, contractors, and researchers. This data helps models build general knowledge and respond more reliably and safely.
