Sam Altman (CEO of OpenAI that made ChatGPT) has just lately been saying that he’s about to make a significant announcement that may upset many traders.
Some folks speculate this will probably be about OpenAI Open-Sourcing one thing. Some suppose he’ll ask for extra regulation. Some suppose he’ll announce an extended delay earlier than GPT5. In reality, OpenAI hasn’t even began coaching it but.
My actually wild hypothesis: “We do not really want GPUs”
The GPT5 delay might have been led to by analysis at OpenAI resulting in discovery of a lot less expensive GPU-free LLM algorithms, and that these algorithms could not but be fairly prepared for prime time.
The “disappointing traders” warning can be as a result of cloud providers involving GPUs wouldn’t be wanted for language Understanding henceforth; they might nonetheless be important for photographs, video, speech, sound, scientific functions, and so forth. This might upset many budgets and corporations promoting GPUs.
These GPU-free Pure Language Understanding (NLU) algorithms exist. I’ve been researching LLMs in my firm Syntience Inc since 2001. Our product is a smaller, sooner, cheaper form of LLM that we now name an SSM – a Small Syntax Mannequin. We are able to create a “helpful” SSM on a laptop computer in underneath 5 minutes utilizing a mere 5MB of corpus, and with out utilizing a GPU. We have now a UM1 demo server within the cloud that hundreds a small SSM discovered for only a few hours. Code to check this demo server is posted on GitHub.
Virtually a 12 months in the past I posted a abstract of how my SSMs are created and the way they’re used on my predominant publishing website. Chapter 8 discusses the “OL” studying algorithm and Chapter 9 the cloud primarily based “UM1” runtime service. Word that the language on this one 12 months previous chapter doesn’t use the time period “SSM” since I solely began utilizing it just lately.

I’ve a “just-so” story that I made up from entire fabric as a result of I wasn’t within the room when it occurred. Take into account this fictitious state of affairs:
Someday between 2006-2014 folks like Geoff Hinton get Deep studying (DL) working nicely for Understanding photographs.
By that point, and possibly independently, some NLP researcher(s) invent termvectors and word2vec. These concepts present the performance for the well-known equation of KING – MAN + WOMAN = QUEEN by permitting for Linear Algebra to work in a high-dimensional semantic idea area.
It’s now a pure step for DL researchers to try to Perceive human language by changing the enter textual content to an odd form of “picture” utilizing time period vector lookup for the interpretation from, nicely, phrases to vectors. After which to make use of the Picture Understanding algorithms they’d already developed to Perceive textual content.
And this labored very well, and was the idea for a few years of speedy enchancment in DNN primarily based NLU.
However my principle (on this fictitious story) is that they acquired too fortunate too early.
They went with time period vectors as a result of it labored. And by no means bothered trying to find a less expensive different.
So these algorithms are ranging from the semantics (of phrases on the phrase degree) imported from the surface (as gathered by word2vec) and so they then try and study the syntax of the language from the primary studying corpus. I name these Semantics-First algorithms.
When studying syntax, they are going to be schlepping round these termvectors. Which could be very costly. Which is why they should run on highly effective and costly GPUs.
Crucial algorithm in a Deep Neural Community stack is Convolution. That is used for correlation discovery. In photographs, correlation discovery requires that a number of passes be revamped the entire picture, performing numerous matrix operations utilizing Linear Algebra.
In textual content, all potential correlations are within the (linear) previous textual content that has already been learn and they are often discovered utilizing indexing strategies reminiscent of these used for internet search. A simpler indexing methodology able to preserving way more context is a neural community utilizing discrete neurons. That is what we use, and is mentioned in Chapter 9.
So in accordance with my just-so story, the ML neighborhood turned a 1-Dimensional listed correlation lookup right into a 2D convolution that required trying to find these correlations. And there’s extra: the convolution have to be completed repeatedly earlier than it converges, as a result of adjusting weights partially invalidates earlier efforts.
And these DL algorithms function in an Euclidean area, which suggests distance measurements contain squares of a whole bunch of floating level numbers and sq. roots. In distinction, my SSMs use Jaccard distance in a good higher-dimensional boolean area. Most of my algorithms are primarily based on set principle.
These are the explanations LLMs value OpenAI on the order of $Billions to coach their LLMs. GPUs are costly.
Studying language immediately, character by character, is definitely one million occasions sooner than utilizing termvectors. It produces SSMs as a substitute of LLMs, as a result of it didn’t begin with semantics. We all know SSMs can deal with classification. Can they deal with dialog?
No person is aware of.
Are time period vectors actually vital for dialog?
No person is aware of.
Or maybe OpenAI is aware of.
My algorithm, Natural Studying, has been working since 2017 however I don’t have a machine that’s sufficiently big to study past what we wanted for classification. We’re utilizing 10 years previous Apple Macintosh Professional Late 2103 machines for all our analysis.
OpenAI actually has the funding, compute, and expertise they would wish with a view to change to Syntax-First algorithms like mine. There might be others engaged on related concepts, and I predict we are going to see extra analysis exercise on this space now that we all know it’s potential to at the very least get this far.
My firm wants a 4TB RAM server with about 220 threads for studying numerous launch variations of classifiers in a number of languages and for experiments aimed toward studying sufficient to have the ability to conduct a dialog within the type of ChatGPT on a millionth of their finances.
We’re self-funded and can’t afford such experiments.
