### Use the `response_model_exclude_unset` parameter { #use-the-response-model-exclude-unset-parameter }

You can set the *path operation decorator* parameter `response_model_exclude_unset=True`:

{* ../../docs_src/response_model/tutorial004_py310.py hl[22] *}

and those default values won't be included in the response, only the values actually set.
