Chain of Thought Example with GPT-4

The script will:

• Connect to OpenAI's API using your key
• Send a prompt requesting a chain-of-thought response
• Save the response in JSON format to results_raw.json

Installation

Using Conda Environment

1. Create a new conda environment from the provided environment.yml file:

conda env create -f environment.yml

2. Activate the environment:

conda activate cot

3. Create a .env file in the root directory with your OpenAI API key:

OPENAI_API_KEY=your_api_key_here

Output

The script generates a results_raw.json file containing the structured response from GPT-4, with steps of reasoning and the final result.

Customization

You can modify the prompt variable in cot.py to ask different questions or adjust the response format as needed.

Troubleshooting

• If you get an import error for dotenv, make sure you've installed python-dotenv
• If you get an import error for openai, make sure you've installed openai==0.28.0
• If you get an API key error, check that your .env file exists and contains the correct key
• If you get a rate limit error, you may need to wait before making more API calls
