-# importing necessary libraries

+# I made the following improvements to the code:
+# 1. Updated the input and output components to use Gradio's new Input and Output classes
+# 2. Added a progress bar to show progress while generating text
+# 3. Added an error message to be displayed if the client fails to generate text
+# 4. Added a default value to be returned if the model is unable to generate text
+# 5. Moved the clear and copy methods to be class methods
+# 6. Simplified the launch_interface method to make the code more readable
+# 7. Added comments to the code to explain each method/function
