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 increasingly more complicated duties? Can we maintain rising the variety of parameters in these items 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 put up through which I offered an article written for IEEE Spectrum. The article, entitled “Deep Studying’s Diminishing Returns – The price of enchancment is turning into unsustainable“, got here to the identical conclusions as I did (and extra) relating to AI but it surely offered a lot more durable details to again its claims. The claims offered by the authors have been primarily based on an evaluation of 1,058 analysis papers (plus further 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 okay, the computational price scales by okay^9). With this, we principally acquired an equation to estimate simply how a lot cash we’ll must maintain 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, the truth is, contemplating how briskly know-how strikes as of late)? 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 improper manner again in 2021?
I believe I used to be each proper and improper.
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:
If 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 would possibly [cost] seven figures, however it’s not going to go to 9 or ten figures, it’s not potential, 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 must assume in phrases of optimization, by way of price profit
Article for Wired.com, Dec 2019 [emphasis mine]
I agreed with him again then. What I didn’t take into accounts (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 big inflow of cash from different sources always getting into the market. Beneath are current figures relating to investments within the discipline of Synthetic Intelligence:
- Anthropic, a direct rival of OpenAI, acquired not less than $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 referred to as Pi,
- Abound raked in $600 million for its private lending platform,
- SandboxAQ acquired $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 outdated 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 keeping with Jerome Pesenti (and me). Large Tech can, it appears!
Let’s have a look at some contemporary analysis now on this matter.
Yearly the influential AI Index is launched, which is a complete report that tracks, collates, distils, and visualises information and traits associated to AI. It’s produced by a workforce 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 reveals the estimated coaching prices vs publication dates of main AI fashions. Observe that the y-axis (coaching price) is in logarithmic scale.
It’s clear that newer fashions are costing increasingly more. Far more (contemplating the log scale).
For precise coaching price quantities, this graph supplies a neat abstract:
Observe 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 smart.
The place does this depart us? Contemplating the newest 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 offered above your common organisations simply can’t compete any extra. They’ve dropped out. It’s simply the large boys left within the sport.
In fact, the large boys have huge reserves of cash so the race is on, for positive. We may maintain going for some time like this. Nonetheless, it’s absolutely honest to say as soon as once more that this type of progress is unsustainable. Sure, extra fashions will maintain rising which might be going to get higher and higher. Sure, increasingly more cash can be dropped into the kitty. However you may’t maintain transferring to the appropriate 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 (except a major breakthrough comes alongside that adjustments the best way we do issues – I mentioned this matter in my earlier two posts).
The craziness that large tech has dropped at this entire saga is thrilling and it has prolonged the lifetime of AI fairly considerably. Nonetheless, the truth that solely large gamers are left now who’ve wealth at their disposal bigger than most nations on the earth 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 improper. I actually hope I’m as a result of I would like this to maintain going. It’s been enjoyable.)
