Question about the Chatgpt version

@wenhuchen 
Hi,

I noticed you posted the ChatGPT score [here](https://github.com/TIGER-AI-Lab/Program-of-Thoughts/blob/main/benchmark.md#:~:text=Params-,GSM8K,-TheoremQA). Could you please let me know which version of ChatGPT was used to obtain this score?

Thank you!
