OpenAI's Private Safety Processing Monitors for Misuse Across Sessions, Retains Zero Customer Data

OpenAI announced Private Safety Processing on August 19, 2026, previewed to select customers. The automated system monitors inputs and outputs across multiple conversation sessions for potential misuse while retaining none of the customer's data. If triggered, it sends a "narrowly defined signal" to OpenAI. The approach contrasts with Anthropic's 30-day data retention policy for covered models including Mythos-class and Fable.
