When is it better to do without a model using the Slim framework and eloquent?

Question

Slim Framework

The documentation for Slim in the Eloquent section has an example of using it without creating a model, when we simply get an object from the base in the container, and then pass it to the class we need.

$container[App\WidgetController::class] = function ($c) {
    $view = $c->get('view');
    $table = $c->get('db')->table('table_name');
    return new \App\WidgetController($view, $logger, $table);
};

I also saw examples where a model is created, and through this model we receive data.

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class User extends Model
{
    protected $table = 'users';
}

The question is - what is the difference, and in which cases which option should be used?
