Include a model class without initialize it.

Yes, CI keeps a list of instantiated object. You should be using the subclass_prefix setting in config/config.php, then loading the model normally (http://ellislab.com/codeigniter/user-gui...aries.html).

If your subclass_prefix is MY_ (default), you would have MY_Model as your base class, then you would extend that class, and load it normally.

MY_Model.php

Code:

class MY_Model extends Model {
    // Some code
}

other_model.php

Code:

class Other_model extends MY_Model {
  // Some code
}

Controller

Code:

$this->load->model('other_model')
