I also took it up on its offer to do a sensitivity analysis. Aside from how it did that, look at how it problem-solved when it lost access to the original data (I apparently waited too long before asking it to continue). Data cleaning, analysis, problem solving, inference...

I would also note that the calculations, code & graphs all appear to be correct based on my spot checks, but it incorrectly gives two numbers in the text (even though it calculates & reports them in the graphs & analysis correctly) I expect that to improve when fully using GPT-4

Code Interpreter really is the biggest thing I have seen in AI since GPT-4 (which wasn't that long ago, but still). It can take 100MB files, do analyses, write and execute code, and give you files as downloads. Not even sure about its limits yet.

Another example.
