This code uses a pre-trained language model checkpoint to generate script text.  That means that you are downloading a model that is already trained, so you do not need to train the model yourself.  You can use the model as the basis for your own training if you need the model to produce different results which are more applicable to your production pipeline.  Otherwise, as long as the pre-trained model meets your usage criteria, it is ready to use "as-is."
