Streaming Request Notes

The Chat Completions API does not include usage in streaming responses by default. For billing convenience, this system will always include usage in streaming responses:

  • If the request body does not contain stream_options, {"include_usage": true} will be added automatically
  • If stream_options already exists, include_usage will be forced to true
