Cuando añades `examples` dentro de un modelo de Pydantic, usando `schema_extra` o `Field(examples=["algo"])`, ese ejemplo se añade al **JSON Schema** para ese modelo de Pydantic.

Y ese **JSON Schema** del modelo de Pydantic se incluye en el **OpenAPI** de tu API, y luego se usa en la interfaz de documentación.
