OpenAI has announced Zero Data Retention (ZDR) for frontier-model deployments and a new Private Safety Processing layer for enterprise customers. The combination is designed to address a difficult enterprise AI requirement: keeping sensitive prompts and responses under customer control while preserving safety monitoring that can identify harmful or policy-violating patterns.
According to OpenAI's announcement on Zero Data Retention for frontier models, ZDR means OpenAI will not retain customer prompts or model responses after an individual request. Enterprise data also will not be used to train OpenAI models unless the customer explicitly opts in. The announcement is particularly relevant for regulated organizations that need clearer boundaries around data handling before deploying frontier models in sensitive workflows.
What OpenAI announced
The most consequential change is the proposed data-control model for eligible frontier-model deployments. Under ZDR, OpenAI says customer content can remain on infrastructure controlled by the customer. Alternatively, content can be stored on OpenAI infrastructure using encryption keys controlled by the customer, so OpenAI personnel do not hold copies of those keys.
