What algorithms specifically show the most results upon improvement? Going into this I thought the jump of improvements were really related more advanced automated tuning and result correction, in which it could be done at scale as it were allowing a small team of data scientists to tweak the models until desired results were being achieved.

Are you saying instead, that concrete predictive algorithms need improvement or are we lumping the tuning into this?

Nah - GPT-4 is crazy expensive, paying 20$/mo only get's you 25messages/3hours and it's crazy slow. The api is rather expensive too. I'm pretty sure that GPT-4 is ~1T-2T parameters, and they're struggling to run it(at reasonable performance and profit). So far their strategy has been to 10x the parameter count every GPT generation, and the problem is that there's diminishing returns everytime they do that. AFAIK they…

I don't think this argument really holds up. GPT3 on release was more expensive ($0.06/1000 tokens vs $0.03 input and $0.06 output for GPT4). Reasonable to assume that in 1-2 years it will also come down in cost.

> Reasonable to assume that in 1-2 years it will also come down in cost.

Definitely. I'm guessing they used something like quantization to optimize the vram usage to 4bit. The thing is that if you can't fit the weights in memory then you have to chunk it and that's slow = more gpu time = more cost. And even if you can fit it in GPU memory, less memory = less gpus needed.

But we know you _can_ use less parameters, and that the training data + RLHF makes a massive difference in quality. And the model size linearly relates to the VRAM requirements/cost.

So if you can get a 60B model to run at 175B's quality, then you've almost 1/3rd your memory requirements, and can now run (with 4bit quantization) on a single A100 80GB which is 1/8th the previously known 8x A100's that GPT-3.5 ran on (and still half GPT-3.5+4bit).

Also while openai likely doesn't want this - we really want these models to run on our devices, and LLaMa+finetuning has shown promising improvements (not their just yet) at 7B size which can run on consumer devices.

We need more data efficient neural network architectures. Transformers work exceptionally well because they allow us to just dump more data into it, but ultimately we want to learn advanced behavior without having to feed it Shakespeare

Saying “hey don’t go down the path we are on, where we are making money and considered the best in the world.. it’s a dead end” rings pretty hollow.. like “don’t take our lunch please?” Might be a similar statement it feels..

Yeah I am noticing this as well. GPT enables you to do difficult things really easily, but then it is so expensive you would need to replace it with custom code for any long term solution.

For example: you could use GPT to parse a resume file, pull out work experience and return it as JSON. That would take minutes to setup using the GPT API and it would take weeks to build your own system, but GPT is so expensive that building your own system is totally worth it.

Unless they can seriously reduce how expensive it is I don't see it replacing many existing solutions. Using GPT to parse text for a repetitive task is like using a backhoe to plant flowers.

I think it's unlikely that the first model to be widely considered AGI will be a transformer. Recent improvements to computational efficiency for attention mechanisms [0] seem to improve results a lot, as does RLHF, but neither is a paradigm shift like the introduction of transformers was. That's not to downplay their significance - that class of incremental improvements has driven a massive acceleration in AI capabilities in the last year - but I don't think it's ultimately how we'll get to AGI.

"...for the current cycle, in our specific public-facing market."

As most here well know "over" is one of those words like "never" which particularly in this space should pretty much always be understood as implicitly accompanied by a footnote backtracking to include near-term scope.

>"the company’s CEO, Sam Altman, says further progress will not come from making models bigger. “I think we're at the end of the era where it's going to be these, like, giant, giant models,” he told an audience at an event held at MIT late last week. “We'll make them better in other ways.” So to reiterate, he is not saying that the age of giant AI models is over. Current top-of-the-line AI models are giant and likely…

Quality over quantity. Just building a model with a gazillion parameters isn't indicative of quality, you could easily have garbage parameters with tons of overfitting. It's like megapixel counts in cameras: you might have 2000 gigapixels in your sensor, but that doesn't mean you're going to get great photos out of it if there are other shortcomings in the system.

What overfitting? If anything, LLMs suffer from underfitting, not overfitting. Normally, overfitting is characterized by increasing validation loss while training loss is decreasing, and solved by early stopping (stopping before that happens). Effectively, all LLMs are stopped early, so they don't suffer from overfitting at all.

Once you've trained on the internet and most published books (and more...) what else is there to do? You can't scale up massively anymore.
