To detect abuse, an identifier converted into a form that cannot directly identify the user is also sent. The content of the tasks sent is not stored on the management team's servers. The management team records only the amount of usage needed to manage usage limits. OpenAI does not use data received through its API to train AI models. However, under OpenAI's policies, the data may be retained for up to 30 days to monitor for abuse.
