Big brain tech dude got yet another clueless take over at HackerNews etc? Here's the place to vent. Orange site, VC foolishness, all welcome.

This is not debate club. Unless it’s amusing debate.

So I signed up for a free month of their crap because I wanted to test if it solves novel variants of the river crossing puzzle.

Like this one:

You have a duck, a carrot, and a potato. You want to transport them across the river using a boat that can take yourself and up to 2 other items. If the duck is left unsupervised, it will run away.

Unsurprisingly, it does not:

https://g.co/gemini/share/59b024d0908b

The only 2 new things seem to be that old variants are no longer novel, and that it is no longer limited to producing incorrect solutions - now it can also incorrectly claim that the solution is impossible.

I think chain of thought / reasoning is a fundamentally dishonest technology. At the end of the day, just like older LLMs it requires that someone solved a similar problem (either online or perhaps in a problem solution pair they generated if they do that to augment the training data).

But it outputs quasi reasoning to pretend that it is actually solving the problem live.

I'm kinda tired, but this puzzle's shoved itself into my brain. The obvious solution I can see is, roughly speaking:

  1. Take the duck and carrot across

  2. Take the duck back

  3. Take the duck and potato across

Yeah, exactly. There's no trick to it at all, unlike the original puzzle.

I also tested OpenAI's offerings a few months back with similarly nonsensical results: https://awful.systems/post/1769506

All-vegetables no duck variant is solved correctly now, but I doubt it is due to improved reasoning as such, I think they may have augmented the training data with some variants of the river crossing. The river crossing is one of the top most known puzzles, and various people have been posting hilarious bot failures with variants of it. So it wouldn't be unexpected that their training data augmentation has river crossing variants.

Of course, there's very many ways in which the puzzle can be modified, and their augmentation would only cover obvious stuff like variation on what items can be left with what items or spots on the boat.

It's just overtrained on the puzzle such that it mostly ignores your prompt. Changing a few words out doesn't change that it recognises the puzzle. Try writing it out in ASCII or uploading an image with it written or some other weird way that it hasn't been specifically trained on and I bet it actually performs better.

Not really. Here's the chain-of-word-vomit that led to the answers:

Note that in "its impossible" answer it correctly echoes that you can take one other item with you, and does not bring the duck back (while the old overfitted gpt4 obsessively brought items back), while in the duck + 3 vegetables variant, it has a correct answer in the wordvomit, but not being an AI enthusiast it can't actually choose the correct answer (a problem shared with the monkeys on typewriters).

I'd say it clearly isn't ignoring the prompt or differences from the original river crossings. It just can't actually reason, and the problem requires a modicum of reasoning, much as unloading groceries from a car does.
