Hmmm, 2-3 high end GPUs implies it's likely not very far off from mainstream. Maybe runnable on the average device within 10-20 years... perhaps even sooner if the model/software can be optimized?

20 years?

In 20 years I'll still be alive and enjoying myself. Does 20 years seem long to you?

This post [0] is a good primer and they are talking about a 20b model gpt3 has 175b. Their other posts go more into details but yes, it really is a massive operation. Some hard facts from here [1] talking about BLOOM with 175b parameters.. >> Installing the full 175B version is a challenge though as it requires around 350GB of GPU VRAM, which is not something one can easily afford. But hey why deploy a model like cha…

So it sounds like this is a question of loading the model into VRAM, and not a question of the cost of a single query. I assume once a model is loaded, many queries can be serviced by that model quickly. There's nothing incorrect about my assertion. If it were to actually take many GPUs to service one query, then there is no mass scale cost viable consumer product. That's just a clear economic fact. Regardless if a m…

You really are like a chatbot... look at the last three node sizes and the density of ram in them. It's not gonna happen as fast as you dream about it especially not with the discounts of the last Gens. The hope is to go to fp4 if you want to run it on consumer hardware and we are still not talking to about 2-3 cards. Why not at least try to Google before hammering down on stupid and uninformed hot takes?

So what's the level of effort to create ChatGPT equivalent products? Is it something where we'll have 100s of competing AIs, or is it gated to only a few large companies?

Given the large number of competitors already announced to ChatGPT, I fail to see how the space will be easily defensible or monetizable (despite large valu…

How much of this is the language vs the vast amount of passably accurate domain knowledge? ChatGPT etc. seem magic because they can answer questions about virtually anything with a high degree of plausibility. It often gets specific facts wrong, but the general contours are correct. Many of us know a lot of trivia/specialist knowledge, but I don't think anyone is as broadly informed as ChatGPT appears to be. It's not clear where the language ends and the encyclopedic knowledge starts, but the latter must be taking up a very large amount of the space in the model.

Looks like FLOP/s per $ are doubling every ~3 years for high end cards, and 10x in ~10 years. So probably not that far off for desktop users.

Read about "RNN Vanishing Gradients". LSTMs help here, but see eg https://medium.com/analytics-vidhya/why-are-lstms-struggling... for the problems there.

My understanding that LSTM is a kind of RNN.

Yes it is. They were developed to fix the vanishing gradient problem.

The 1997 paper where they were introduced puts it like this:

Learning to store information over extended time intervals by recurrent backpropagation takes a very long time, mostly because of insufficient, decaying error backflow. We briefly review Hochreiter's (1991) analysis of this problem, then address it by introducing a novel, efficient, gradient-based method called long short-term memory (LSTM). Truncating the gradient where this does not do harm, LSTM can learn to bridge minimal time lags in excess of 1000 discrete-time steps by enforcing constant error flow through constant error carousels within special units.

Usually they aren't competitive with transformers on long-range understanding problems though.

I’d be surprised if there weren’t any algo breakthroughs before that to make these several times faster (10x?).

(such as are all of the weights really needed all of the time, or could you load different ones based on recent context?)

If in 10 years on top of that you’d have that 10x faster hardware as well, you might be running GPT-3s as just a subcomponent of games/apps.

Pretty cool!

Honestly even if it were to take a few minutes per response, that's likely sufficient for many use cases. I'd get value out of that if it allowed bypassing a paywall. I'm curious how these models end up being monetized/supported financially, as they sound expensive to run at scale.

The required disk space seems the biggest barrier for local.

Datasets.

The one with the largest, most personal, most obtrusive, invasive dataset will probably win.

The one that has absorbed every podcast, every youtube video, every close-caption text in existence, will have the most "complete" answers.

fp4 ?= float point of 4 bits??? I was already mind blown by floats of 8b, how can you fit any float precision in 4b?
