 * This policy can be used multiple times per policy definition.
 * This policy can optionally be configured when adding an API from the Azure OpenAI Service using the portal.
+* Certain Azure OpenAI endpoints support streaming of responses. When `stream` is set to `true` in the API request to enable streaming, prompt tokens are always estimated, regardless of the value of the `estimate-prompt-tokens` attribute.
