Bottom line: OpenAI is sticking with zero data retention for API customers and announcing Private Safety Processing, an approach intended to enable safety checks without persistent data storage.
OpenAI has reaffirmed its zero data retention (ZDR) option for eligible API customers and introduced a concept called “Private Safety Processing” designed to enable advanced AI safety checks without compromising customer data privacy.
OpenAI has once again confirmed its existing zero data retention (ZDR) option for the API. Eligible customers can continue to ensure that input and output data submitted via the API are not stored beyond the duration necessary to process the request. The announcement falls within the context of the company’s frontier models and is aimed at organizations with heightened data protection and compliance requirements.
In addition, OpenAI is announcing a concept called Private Safety Processing. This is intended to allow advanced AI safety mechanisms — for example, for detecting abuse or problematic content — to operate without customer data having to be permanently stored or analyzed for other purposes. OpenAI does not disclose technical details on the concrete implementation in the announcement, such as the methods used or the timeline for availability.
For CISOs, the combination of ZDR and a safety-oriented processing model is relevant because it addresses two frequently competing requirements: regulatory data minimization requirements on the one hand, and the need for content and abuse checks on the other. Organizations using OpenAI models for use cases involving sensitive or personal data should verify whether their own contractual arrangement covers the ZDR option and what contractual or technical evidence OpenAI provides for it.
Until further details on Private Safety Processing become available, the existing ZDR arrangement remains the primary, reliable anchor point for security officers conducting data protection assessments and audit processes as part of third-party risk management.
