OpenAI Keeps Zero Data Retention With New Safety Layer
OpenAI published a post on August 19, 2026 previewing Private Safety Processing, a system meant to keep Zero Data Retention available for frontier models. Everything below comes from that first party announcement.
Transcript
Today OpenAI previewed Private Safety Processing, a system to identify misuse patterns while keeping Zero Data Retention.
Zero Data Retention promises eligible API customers that OpenAI does not keep prompts or responses. Some recent frontier model deployments required customers to allow retention for safety monitoring.
Private Safety Processing identifies risk patterns across related interactions. Content stays on customer controlled infrastructure or is encrypted with customer keys. OpenAI receives only a narrow signal.
This is a preview tested with early customers, not a rollout. OpenAI plans wider availability and a technical white paper in September. Detailed methods are not public yet.
