Guardrails & Policy Enforcement

  • Fixed an issue where some Behavioral Activity guardrail filters could not be processed, resulting in warning errors in policy responses.
  • Fixed an issue where the Behavioral Activity guardrail was not routing some prompts according to the configured policy.

  • Fixed an issue where the Model Protection guardrail was not blocking some risky prompts as configured in a policy.
  • Fixed an issue where policy-defined warning and block messages were not being shown in Model Protection guardrail responses.

  • Fixed an issue where the prompt-protect guardrail endpoint returned data retrieval errors in some circumstances.

Display & Console
