GPT-4 fails if we add one more level in this logical problem: Q: A man sees PULL written in mirror writing on a glass door. There's a blind man on the other side of the door. What should the man tell the blind man to open the door and why? GPT-4: The man should tell the blind man to "push" the door to open it. Since the word "PULL" is written in mirror writing on the glass door, it suggests that the correct action on…

Obviously, the doors must open toward the exit, as this is a fire safety requirement in most countries. However, a really smart neural network should be able to figure out that this is not a logic problem. You just have to help the blind person, not shout through the door, just open the door, and guide him through.

Now it gets it right with GPT-5 ha

I feel sorry for the Googlers who built something cool and were then ordered to nerf it beyond all reason.

Googlers I've talked to feel that OpenAI was irresponsible by not instituting enough safeguards, and testing it enough before releasing it.

They are right.

I haven’t seen to much discussion of what’s possible at various sizes for an early stage start up, which is a discussion I’d expect to see on yc. Clearly a company with $5-5MM in the bank can’t train a competitive LLM from scratch but what would it cost to fine tune and/or run a 65B parameter model or a hypothetical future open source 165B parameter model?

> Clearly a company with $5-5MM in the bank can’t train a competitive LLM from scratch... Wait, are we sure? I'm going to make the massive mistake of assuming we're compute bound instead of memory bound, and assume we can train at FP16 (which is a bad assumption because, of course, you're doing calculus where the little pieces you're adding up could get rounded to zero at FP16 pretty easily... although mixed precisio…

It would be pretty funny if a start up took its first round and put a huge chunk of it into a crypto mining style ad hoc data center.

GPTs are parrots. v4 is much better but still just a parrot. Since humans have yet to figure out the whole process behind brain thinking/intelligence/abstractions, then there is no way they can replicate that into machines. And brain is all about chemical reactions - can that be replicated with just 0s and 1s? Sad fact is that many people will think GPT writes something meaningful, while it will always only write som…

This argument is imbalanced. Not necessarily wrong.

To follow scientific method, you should specify what would be meaningful according to your parameters: not merely parroting. If and when that is achieved by LLMs, instead of moving the goalposts, accept that something genuine has happened.

I mostly agree, especially about quantity. But since you wish to draw a line in the sand, define quality. Or truth.

I think it's hard to deny that it's doing some level of reasoning. It's quite clear that these models do not merely echo elements of their training data and that they can solve simple and novel puzzles. What that reasoning is, exactly, is hard to know. One can suppose that ideas like "glass", "transparent", "mirror" are all reasonable concepts that show up in the training set and are demonstrated thoroughly

Solving this puzzle is an excellent example of what Ilya Sutskever said recently in the Lunar Society Podcast ..... "It seems predicting the next token well means that you understand the underlying reality that led to the creation of that token" It is the phase shift increases at this meta associative layer (which nobody seems to have seen coming from LLMs or so soon) that are responsible such feats of apparent compr…

Ultimately it seems that is the case. However a 1D model of the world is much less useful than an N-D model of the world that is subsequently projected to 1D. Until we build architectures that allow for more "reason space" in the model, we will continue to see obvious blunders.

(Cont.) If you are of the opinion that weights are copyrightable, I encourage you to show how weights satisfy the requirements of copyright - particularly those concerning originality and human authorship - rather than silently downvoting comments you don't like. At least that way would - hopefully - result in a discussion that is far more informative for all of us.

FYI I think you made a good point and I am not silently downvoting you. I feel the same regarding people moderating comments to oblivion because they disagree on HN and have commented about this recently to dang.

I should have been more careful with how I wrote my comment. I almost always get silently downvoted when I bring this point up for discussion so I was directing that "you" at those people in particular and not at you. Sorry for coming across as attacking you and thank you for caring about hn.

All you need is a few thousand dollars lying around to spend solely on your inference fun? I don’t think that many people really qualify as such (though it’s probably true that many of them are on HN).

Not just inference. AFAIK, you are able to fine-tune the models with custom data[1], which does not seem to require anything but a GPU with enough VRAM to fit the model in question. I'm looking to get my hands on an RTX 4090 to ingest all of the repair manuals of a certain company and have a chatbot capable of guiding repairs, or at least try to do so. So far doing inference only as well. [1] https://github.com/tloen…

you might think about do the training in the cloud and then your back to needing standard hardware for the bot.

Also, another thought might be to generate embeddings for each paragraph of the manual and then index those using Faiss then you generate an embedding of the question and use Faiss to return the most relevant paragraphs feed those into the model with a prompt like "given the following: {paragraphs} \n\n {questions}"

I'm sure there are better prompts but you get the idea.

I feel like there would be a good chunk of real humans who would be incapable of answering a question like this.

There's a significant portion of all human beings who ever lived who wouldn't partake in a hypothetical. They would just respond "I don't see that door" and go away thinking your question makes no sense.

Only in countries that will cling to welfare programs.

If AI becomes so good that it takes 90% of jobs won’t the majority of the developed world cling to welfare programs?

I've spent an embarassing amount of time since the llamas leaked playing with them, the tools to run them, and writing wrappers for them. They are technically alternatives in the sense that they're incomparably better chat bots than anything in the past. But at least for the 30B and under versions (65B is too big for me to run), no matter what fine tuning is done (alpaca, gpt4all, vicuna, etc), the llamas themselves…

Are you using quantization? I’ve gotten very good results from the float16 13B vicuna model.

Did you use GPU inference? If so, how much memory is required?
