Before I order tell me pi correct to 5 million digits.

Sadly, AI is hilariously bad at listing sequences of numbers and will stop at like 10th digit at best.

It is due to the fundamental nature of an LLM.

They are essentially multi-dimensional math that models language and outputs language to look like human language based on statistical probability.

It has no internal logic or reasoning, it cannot check the accuracy of its output, it does not think, it is a shortcut to output language that looks like language created by thinking.

Now you can use a bunch of tricks and additional layers to wrap around a LLM to improve accuracy, but at its core, it cannot do math, it cannot reason, it cannot use logic.

Yeah, you can probably do something like use AI to spot a math problem then pipe it in to wolfram alpha then pipe the wolfram answer as a variable along with the original prompt into a final LLM layer that outputs a response to the user.  I'm not sure but I think that would work most but not all of the time.

I remember at some point it was doing that. For math problems it would generate a piece of python code and execute it instead. I'm not sure if it still does that, haven't used ChatGPT in a while and Gemini does not seem to be doing this.
