Y si declaraste un `response_model`, aún se usará para filtrar y convertir el objeto que retornaste.

**FastAPI** usará esa respuesta *temporal* para extraer el código de estado (también cookies y headers), y los pondrá en la respuesta final que contiene el valor que retornaste, filtrado por cualquier `response_model`.
