#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

And by the way, the thing to understand is it's putting down one word at a time.

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

But the outer loop of the fact that it says, okay, I put down a word.

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

Now let's take the whole thing I wrote so far.

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

Let's feed that back in.

#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

Let's put down another word.

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

That outer loop, which seems almost trivial, is really important to the operation of the thing.

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

And for example, one of the things that is kind of funky is it'll give an answer.

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

And you say to it, is that answer correct?

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

And it'll say, no.

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

And why is that happening?

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

It's fascinating, right?

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

Why can it do that?

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

Well, the answer is because it is going, one word at a time, sort of forwards.

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

And it didn't, you know, it came along with some sort of chain of thought, in a sense, and it came up with completely the wrong answer.

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

But as soon as you feed it, the whole thing that it...

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

came up with, it immediately knows that that isn't right.

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

It immediately can recognize that was a bad syllogism or something and can see what happened, even though as it was being led down this garden path, so to speak, it came to the wrong place.

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

That's quite, I'm not sure what to make of it.

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

Well, look, I think there are many things we don't understand.

#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

Okay, so for example, 175 billion weights, it's maybe about a trillion bytes of information, which is very comparable to the training set that was used.
