The GPT-like models will have always problems with hallucinating, the newer models might limit it extent, but they still might be useful in summarisation/exploring a data of user,
we should be cautious not to be overconfident with them and to believe everything what hype is saying
I would suggest to make the solution as flexible as possible to use other APIs as well, locking everything with OpenAI is bad idea in long term, there is more inititiatives like the open source Hugging chat
For people who want use ChatGPT now, the scripts using Python integration posted in this repo could be useful, I didn’t try them
EDIT: there is a separate thread about this Python integration
