**FastAPI** will take that model, generate its JSON Schema and include it in the correct place in OpenAPI.

For example, to declare another response with a status code `404` and a Pydantic model `Message`, you can write:

{* ../../docs_src/additional_responses/tutorial001_py39.py hl[18,22] *}

/// note

Keep in mind that you have to return the `JSONResponse` directly.
