En este caso, como los dos modelos son diferentes, si anotáramos el tipo de retorno de la función como `UserOut`, el editor y las herramientas se quejarían de que estamos devolviendo un tipo inválido, ya que son clases diferentes.

Por eso en este ejemplo tenemos que declararlo en el parámetro `response_model`.

...pero sigue leyendo abajo para ver cómo superar eso.

In the previous example, because the classes were different, we had to use the `response_model` parameter. But that also means that we don't get the support from the editor and tools checking the function return type.

But in most of the cases where we need to do something like this, we want the model just to **filter/remove** some of the data as in this example.
