           How do I fix InternalServerError - 500 - Failed to create completion as the model generated invalid Unicode output?
         answer:
           You can minimize the occurrence of these errors by reducing the temperature of your prompts to less than 1 and ensuring you're using a client with retry logic. Reattempting the request often results in a successful response.

+          We noticed charges associated with API calls that failed to complete with status code 400. Why is failed called generating a charge? 
+        answer:
+          If the service performs processing, you will be charged even if the status code is not successful (not 200).
+          Common examples of this are, a 400 error due to a content filter or input limit, or a 408 error due to a timeout. Charges will also occur when a `status 200` is received with a `finish_reason` of `content_filter`.
+          In this case the prompt did not have any issues, but the completion generated by the model was detected to violate the content filtering rules which results in the completion being filtered. 
+
+          If the service doesn't perform processing, you won't be charged.
+          For example, a 401 error due to authentication or a 429 error due to exceeding the Rate Limit.
