Almost three years in the past (July 2021) I wrote an article on this weblog arguing that synthetic intelligence is slowing down. Amongst different issues I said:
[C]an we continue to grow our deep studying fashions to accommodate for an increasing number of complicated duties? Can we preserve growing the variety of parameters in this stuff to permit present AI to get higher and higher at what it does. Certainly, we’re going to hit a wall quickly with our present know-how?

Then 7 months later I dared to put in writing a sequel to that submit by which I introduced an article written for IEEE Spectrum. The article, entitled “Deep Studying’s Diminishing Returns – The price of enchancment is changing into unsustainable“, got here to the identical conclusions as I did (and extra) concerning AI nevertheless it introduced a lot more durable details to again its claims. The claims introduced by the authors had been based mostly on an evaluation of 1,058 analysis papers (plus extra benchmark sources).
A key discovering of the authors’ analysis was the next: with the rise in efficiency of a DL mannequin, the computational price will increase exponentially by an element of 9 (i.e. to enhance efficiency by an element of ok, the computational price scales by ok^9). With this, we principally obtained an equation to estimate simply how a lot cash we’ll have to preserve spending to enhance AI.
Right here we’re, then, 3 years on. How have my opinion items fared after such a prolonged time (an eternity, in truth, contemplating how briskly know-how strikes today)? Since July 2021 we’ve seen releases of ChatGPT, Dall-E 2 and three, Gemini, Co-Pilot, Midjourney, Sora… my goodness, the checklist is limitless. Immense developments.
So, is AI slowing down? Was I proper or mistaken manner again in 2021?
I feel I used to be each proper and mistaken.
My preliminary declare was backed-up by Jerome Pesenti who on the time was head of AI at Fb (the present head there now could be none apart from Yann LeCun). In an article for Wired Jerome said the next:
Once you scale deep studying, it tends to behave higher and to have the ability to remedy a broader process in a greater manner… However clearly the price of progress is just not sustainable… Proper now, an experiment may [cost] seven figures, however it’s not going to go to 9 or ten figures, it’s not attainable, no person can afford that…
In some ways we have already got [hit a wall]. Not each space has reached the restrict of scaling, however in most locations, we’re attending to a level the place we actually have to assume in phrases of optimization, when it comes to price profit
Article for Wired.com, Dec 2019 [emphasis mine]
I agreed with him again then. What I didn’t consider (and neither did he) was that Large Tech would get on board with the AI mania. They’re able to dumping 9 or ten figures on the drop of a hat. And they’re additionally able to fuelling the AI hype to take care of the massive inflow of cash from different sources consistently getting into the market. Under are current figures concerning investments within the area of Synthetic Intelligence:
- Anthropic, a direct rival of OpenAI, obtained at the very least $1.75 billion this 12 months with an extra $4.75 billion accessible within the close to future,
- Inflection AI raised $1.3 billion for its very personal chatbot known as Pi,
- Abound raked in $600 million for its private lending platform,
- SandboxAQ bought $500 million for its concept to mix quantum sensors with AI,
- Mistral AI raised $113 million in June final 12 months regardless of it being solely 4 weeks previous on the time and having no product in any respect to talk of. Loopy.
- and the checklist goes on…
Staggering quantities of cash. However the large one is Microsoft who pumped US$10 billion into OpenAI in January this 12 months. That goes on high of what they’ve already invested within the firm.
US$10 billion is 11 figures. “[N]obody can afford that,” in line with Jerome Pesenti (and me). Large Tech can, it appears!
Let’s have a look at some recent analysis now on this matter.
Yearly the influential AI Index is launched, which is a complete report that tracks, collates, distils, and visualises knowledge and traits associated to AI. It’s produced by a group of researchers and consultants from academia and business. This 12 months the AI Index (launched this month) has been “essentially the most complete thus far” with a staggering 502 pages. There are some extremely insightful graphs and data within the report however two graphs particularly stood out for me.
The primary one exhibits the estimated coaching prices vs publication dates of main AI fashions. Notice that the y-axis (coaching price) is in logarithmic scale.
It’s clear that newer fashions are costing an increasing number of. Far more (contemplating the log scale).
For precise coaching price quantities, this graph supplies a neat abstract:
Notice the GPT-4 (accessible to premium customers of ChatGPT) and Gemini Extremely estimated coaching prices: US$78 million and US$191 million, respectively.
Gemini Extremely was developed by Google, GPT-4 was de-facto developed by Microsoft. Is sensible.
The place does this depart us? Contemplating the most recent product releases, it looks as if AI is just not slowing down, but. There nonetheless appears to be steam left within the business. However with numbers like these introduced above your common organisations simply can’t compete any extra. They’ve dropped out. It’s simply the massive boys left within the sport.
In fact, the massive boys have huge reserves of cash so the race is on, for certain. We may preserve going for some time like this. Nevertheless, it’s absolutely honest to say as soon as once more that this type of progress is unsustainable. Sure, extra fashions will preserve rising which might be going to get higher and higher. Sure, an increasing number of cash can be dropped into the kitty. However you’ll be able to’t preserve shifting to the fitting of these graphs indefinitely. The equation nonetheless holds true that with the rise in efficiency of a DL mannequin, the computational price will increase exponentially. Returns on investments will begin to diminish (until a big breakthrough comes alongside that modifications the best way we do issues – I mentioned this matter in my earlier two posts).
The craziness that large tech has delivered to this complete saga is thrilling and it has prolonged the lifetime of AI fairly considerably. Nevertheless, the truth that solely large gamers are left now who’ve wealth at their disposal bigger than most nations on this planet is a telling signal. AI is slowing down.
(I’ll see you in three years’ time once more after I concede defeat and admit that I’ve been mistaken. I actually hope I’m as a result of I need this to maintain going. It’s been enjoyable.)
