    Example of using OpenAI functions in completions with Python decorators

This example illustrates a way to utilize a function dynamically while querying an OpenAI GPT model. It uses the newly released functions support in the completion endpoints OpenAI provides.
The general concept is based on using a decorator to extract information from a function so it can be presented to the language model for use, and then pass the result of that function back to the completion endpoint for language augmentation.
In general, a wide variety of functions can be swapped in for use by the model. By changing the get_top_stories function, plus the prompt in run_conversation, you should be able to get the model to run your function without changing any of the other code.
Configuration

To use this, create a config.py file and add a variable with your OpenAI token:
# tokens
openai_token = "sk-<token_string>"

Ensure you have the OpenAI library installed:
pip3 install openai

Running

To run the example, do the following:
python3 top_hackernews.py

Sample Output

A sample run, asking for AI stories:
kord@bob PythonGPT $ python3 hackernews_top10.py
