<p>The file model_backend.py makes it easy to work with different AI models
(like OpenAI, Watsonx, or STUB (a fake one for testing)) using the same setup.</p>
<p>It does two main things:</p>

<li>
<p>Creates an arbitrary base class (ABC) called <code>ModelBackend</code>: This class serves as a blueprint for what integrating model backends should follow (OpenAI, Watsonx, or dummy models (STUB)). Its subclasses must implement the abstract run() method to run a
