My worry was more about random failures on Open AI side (I'm building something with it). Thanks for sharing. I'd love to see a blog post on how you are handling the quoting issues.
Are you planning on sticking with Open AI or is it a stop gap until you train your own models?
As for our own models, it depends on the use case. If you click the code assist and type "Insert a pie chart of the sources of income into B3", the Open AI models do a hard to beat (at this point) job. When it comes to fine tuning on a massive stack of existing spreadsheets, published models are a better fit.
