I think one could argue the opposite.

1) Good current generation AIs are specifically trained to reduce hallucinations. If we had new AI system that happened to not have hallucinations as a side effect of their training, then it would be convincing. But here, it looks like we have built a pocket calculator that answer 7+13 = 14, and on top of it, we added a layer that says "if the input is 7+13, then replace the output by 20". This pocket calculator still does not know how to calculate, we just added a layer to hide its mistakes.

2) Not only "make shit up" is not the same as "hallucination" (either "making shit it" is done when the individual knows it is unreliable, or when the individual was given wrong inputs), but the point is not to say "hallucination implies no consciousness", but "large quantities of hallucinations in situations where a conscious system would be unlikely to hallucinate implies no consciousness"

Yeah,don't use GPT for that. It really can't do basic arithmetic.

Try Claude, which can.

Wow, I don't think you understood at all.

First, the "13+7" is an analogy. In this analogy, "13+7" is not the real question you ask, it represents _any questions_, not just arithmetic.

But secondly, did you even noticed that in my example, the system answer CORRECTLY "13+7"? So, in my example, the thing I'm talking about and I argue does not "understand" is Claude, even if it is able to answer correctly.

My point is: the "basic LLM" part is creating a mechanism that answer without understanding (as demonstrated for example by ChatGPT failing arithmetic), and the fine-tuning or the harness is just hiding the lack of understanding by adding ad-hoc correction on the residuals. And because it is on the residuals, it looses the logical links (13+7 -> 20 is "logical", it corresponds to the math logic, it corresponds to what you get when you add 13 stones and 7 stones together. The residual is "14 -> 20", which has no meaning in itself)

The ad-hoc correction is either: 1. by training the model so it learns by heart, without understanding, that the symbols "13+7" should lead to "20", 2. or by training the model to use a pocket calculator without understanding arithmetic so it can do it itself.

You can prove that the model does not understand it very simply. Let's take the normal fine-tuned model M1. Now, let's go back to the pre-tuned version, and fine-tune it so it answer "21" to the question "13+7", and use an harness that does "sum(x, y): return x+y+1". This is model M2. M2 will fail to answer "13+7" correctly, it will say "21". And yet, M2 has been trained exactly the same way M1 was. If it is true that the additional tuning "add understanding", M2 will not be possible, it will say "error, error, do not compute, you try to train me to say that 13+7 is 21, but it does not make logical sense to me". But it does not happen: the pre-tuned model has no idea that 13+7=20 is more logical than 13+7=21, and the additional tuning is just helping him returning a more correct answer while still having no idea where this answer comes from.
