Can We Understand How Large Language Models Reason? (cacm.acm.org)

They dont. They have input that runs through a invisible stochastic canyon. As long as there is previous experience the stochastic canyon never ends. If there is none or isignificant one, or it runs out of tokkens, it hallucinates and the illusion falls apart. There is no reasoning, just the invisible grand canyon of all of human experience and knowledge. PS: try to get it to retell you a clichee movie or book and you can see life near the end, how the delta of all the same movies opens up into wildly different endings.
To advance further it would need the ability to abstract away the general situation shape and pattern recognize similar situations.

Stochastic gradient descent can be likened to traveling down a billion-dimensional canyon. But inference? Hardly.

It’s curious how they solve unsolved math problems without reasoning. Maybe I have a different definition of reasoning than you.

Guess what? SAT solvers have also solved unsolved math problems. Do you believe they are “reasoning”?

My toaster doesn't reason, and neither do the current clankers.

One plausible reason I thought of that we may not understand neural nets is that by their nature their power grows with ever-more complex connections and weights.
So it is like the opposite of logical systems, in that the very design of neural net architecture is a mess of parameter "spaghetti code" which renders the entire thing a metaphorical encrypted black box. The more powerful an AI/AGI the more this would be the case, and this is analogous a complexity curve.
And so any effort to make sense of such black box computation would be like trying to reverse entropy, analogous to trying to recover information lost in waste heat. And that could be one fundamental barrier to understanding both human and artificial brains alike, relative to their internal complexity.
(Just thinking aloud my handwavy pet theory recently, I am not an expert and could be totally mistaken on this)

Clickbait article title.
The article body does not presume they reason.

They don't reason.

Do they ?

The article answers this question, at least to the extent it can be answered, at this time.
We see some signs of reasoning, but also we understand little about how they work.

Do we see actual signs of reasoning or is it anthropomorphism? We have an innate tendency to do so as humans.

Yes, there is an LLM feature that we have anthropomorphized as "reasoning" or "thinking", where an LLM has a scratch space where it can dump tokens that help to improve the final output.

> that help to improve the final output
Do they actually help? Are you sure?

Of course they do, how else do you think they manage to implement new features in large codebases, or to prove new theorems? But you don't even have to assume they do because of the results- you can read their chain of thought.
