Best AI for data analysis and calculations

Hi,

I’ve been using Openai GPT4 api for data analysis and calculations.

But I’ve two questions about it:

  1. What is the best to use for this kind of work: System, Assistant or User?
  2. Is there another AI which can be used with Make that could do this better?

To elaborate, I provide the AI with data (text and numbers) to analyse. This is objective maths, but also data than can be interpreted in several ways and this is where the AI gives slightly different answers every time. The wider conclusion is always the same, but the details can differ, that’s why I am also looking for other, more stable, AI options and I would like to know if I should use User, System or Assistant for this type of work.

Thanks in advance!

Can someone help me with this?
