+Description: A GUI application for interacting with a local Llama vision model.
-import openai
+             Users can upload images or PDFs and ask questions about them.
+Date: 11.11.2024 # Replace with actual date
+Version: 1.0
+Development Environment: Visual Studio Code with Continue.ai (Claude Sonnet 3.5)
+
+This script creates a tkinter-based GUI for uploading images or PDFs,
+sending them to a local Llama 3.2 vision model, and displaying the results.
