Какая разница между input model и view model?

public class User{
        public string Name { get; set; }
        public string Age { get; set; }
    }

@model EditFormApplication.Models.User
    
        @using (Html.BeginForm("Index", "Home", FormMethod.Post))
        {
             @Html.TextBoxFor(model => model.Name)
             @Html.TextBoxFor(model => model.Age)
        <input type="submit" value="Save">
        }
