Hello Noah!
Thaks for the course, you did a great work!
I found some improvements.
OpenAI updated their API and the chat completion API now needs to be formated openai.chat.completions.create(model="gpt-3.5-turbo", messages=messages)

I also had problems with acccesing completion_answer even tho the syntax is correct, I had to change the syntax to completion['choices'][0].message.content

I hope you find this usefull!

Have a great Day!

I had a similar experience and had to format the completion_answer line like this to get it to work:
completion_answer = completion.choices[0].message.content

Updated with y'alls feedback.

Thank you @Jakolo121 & @kellenmace
