The AI-selected “best” poster award

This script, gpt4_group_criteria.py, is a Python script that uses OpenAI's GPT-4V model to perform certain tasks. The script requires an OpenAI API key to function.

Grading Criterion

The script uses the following criterion outlined in the Rubric for Scientific Posters provided by Harvard University's Writing Center:

• Organization
• Graphics
• Data Visualization
• Text
• White Space
• Objectives
• Main Points

How to Use

1. Ensure you have a .env file in your project root with your OpenAI API key. The key should be stored as OPENAI_API_KEY=your_api_key_here.

2. Create a virtual environment using conda or venv, and install the required Python packages using pip install -r requirements.txt.

3. Use the script by running the command python gpt4_group_criteria.py --image_path "./images/path_to_your_poster_file" --result_base_dir "./output_json_files". Replace ./images/path_to_your_poster_file with the path to the image you want to encode, and ./output_json_files with the directory where you want to store the output JSON files.
