Da Vinci Power strikes again

Hello Sir,

May I ask you how you use chatGPT using DaVinci 003?
I mean isn’t it a default?

I am pretty new to OpenAI and just starting, but pretty much like it.
I mostly use it to help myself with Python and SQL tasks.
Is the chatGPT enough for that purpose or I need to go to codex or other models by setting an API?

Thanks!
Zarko
