Zero Data Retention for AI APIs: What It Is, Why Enterprises Need It, and How to Get It

Zero Data Retention (ZDR) means AI providers process customer inputs and outputs only to complete the API request, then discard that content afterward rather than storing prompts, files, or responses in persistent systems. This differs from “no model training” and is essential for enterprises operating under GDPR, HIPAA, or ISO 27001, since retained data creates breach, subpoena, and compliance exposure even when excluded from training pipelines.
