After this change the quoted clause for zero retention is no longer on the page. The answer is flagged until a person re-reads it.

  1. Added: Zero data retention (ZDR) is available on AI Gateway for Pro and Enterprise teams and for any team that has purchased AI Gateway credits. See Availability for details. There are two ways to enforce ZDR:
  2. Removed: Zero data retention (ZDR) is available for Pro and Enterprise users on AI Gateway. There are two ways to enforce ZDR:
  3. Added: Per-request and team-wide ZDR both require a paid account, which means a Pro or Enterprise plan or purchased AI Gateway credits. Hobby teams and teams on a Pro trial can use ZDR once they purchase credits . Free credits don't count.
  4. Added: With an active Token Pass , you can also use per-request ZDR for as long as the pass is active, even after you've used its monthly credit. Turning on team-wide ZDR in the dashboard still requires a Pro or Enterprise plan or purchased AI Gateway credits.
  5. Added: If you request ZDR from a team that isn't eligible, AI Gateway returns a 403 :
  6. Added: AI Gateway checks your payment status again before it returns this error, so a credit purchase usually applies to your next request. If you purchased credits in the last few minutes and still get a 403 , retry shortly.
  7. Added: Pro and Enterprise teams, and teams that have purchased AI Gateway credits, can enable ZDR globally for all requests from the AI Gateway Dashboard . If your team isn't eligible, you can't turn on the toggle, and the settings page links to buying AI Gateway credits. If your team stops being eligible while team-wide ZDR is on, for example after downgrading from Pro, you can still turn it off.
  8. Removed: Pro and Enterprise customers can enable ZDR globally for all requests from the AI Gateway Dashboard .
  9. Added: Team-wide ZDR and team-wide disallow prompt training are separate settings, and turning on one doesn't turn on the other. To enforce both for your team, turn on both the Zero Data Retention and Disallow Prompt Training toggles. Team-wide disallow prompt training has no additional cost.
  10. Added: If your team isn't eligible for ZDR, the request fails with a 403 (see Availability ). If no ZDR-compliant providers are available for the requested model, the request fails with an error:
  11. Added: When ZDR is enabled, successful responses include enabledZeroDataRetention: true in the gateway metadata. The routing.skippedProviderAttempts array lists each provider AI Gateway removed for ZDR, with the reason:
  12. Added: The provider doesn't offer ZDR for this model.
  13. Added: Your BYOK key for this provider isn't marked as ZDR-compliant. See BYOK .
  14. Added: The model retains data, so no provider can serve it with ZDR.
  15. Removed: If no ZDR-compliant providers are available for the requested model, the request fails with an error:
  16. Removed: When ZDR is enabled, the routing metadata in successful responses shows how AI Gateway filtered providers. The planningReasoning field indicates which providers were considered:
  17. Added: If no ZDR-compliant providers are available for the model, the request fails with a no_zdr_providers_available error.
  18. Removed: If no ZDR-compliant providers are available for the model, the request fails with a no_providers_available error.
  19. Added: All ZDR-compliant providers also disallow prompt training, since ZDR is a superset of disallowing prompt training . In some cases, certain models or functionalities may be excluded from a provider's ZDR policy. AI Gateway will not fail these requests if zero data retention is enabled, so review the provider's policy in the table below to understand the nuances of specific tools and how they affect data retention. However, when a model is ineligible for ZDR on every provider, a request for that model with ZDR enabled fails.
