If anyone is curious, a Meta Data Scientist published a great piece about how the facts about what LLMs are actually doing (and therefore able to do) and how it's papered over by using chat bots. It's a long but very engaging read.

This trope of proclaiming some critical flaw in the functioning of LLMs with the implication that they therefore should not be used is getting boring.

LLMs are far from perfect but they can be a very useful tool that, used well, can add significant value in spite of their flaws. Large numbers of people and businesses are extracting huge value from the use of LLMs every single day. Some people are building what will become wildly successful businesses around LLM technology.

Yet in the face of this we still see a population of naysayers who appear intent on rubbishing LLMs at any cost. To me that seems like a pretty bad faith dialogue.

I’m aware that a lot of the positive rhetoric, particularly early on after the first public release of ChatGPT was overstated - sometimes heavily so - but taking one set of shitty arguments and rhetoric and responding to it with polar opposite, but equally shitty, arguments and rhetoric for the most part only serves to double the quantity of shitty arguments and rhetoric (and, adding insult to injury, often does so in the name of “balance”).

You could substitute "LLMs" -> "Humans" and the statement would also be true.

Are you suggesting Humans can't do formal reasoning? Because you can easily teach a four year old not to make illegal moves in chess with very little instructions, and by 10 geniuses like Terence Tao were discussing open math problems with Erdos. If anything this article adds further evidence that whatever the architecture of the human brain it is very different to an LLM architecture.

Integer multiplication was used to test LLMs reasoning capabilities, and I think Karpathy mentioned that tokenization might play a role in basic math. MathGLM was compared against GPT-4 in the article, but I couldn't figure out if MathGLM was trained with character-level tokenization or not.
