Pattern A (Recommended)

Zero-Retention Ephemeral Gateway

Processes payloads strictly in volatile memory, immediately disposing of prompts upon response delivery without disk persistence.

Key Technical Advantages:

  • 100% ephemeral processing
  • Zero upstream model training
  • PII scrubbed in-flight
  • GDPR & HIPAA compliant
Pattern B (Alternative / Legacy)

Vendor Specific Retention

Upstream providers record and cache raw customer prompts for 30 days to 1 year for abuse monitoring or prospective model re-training.

Characteristics & Trade-Offs:

  • Audit trail available on provider dashboard
  • Provider-managed moderation logs
  • Debug replay capability
