Practically 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 advanced duties? Can we hold rising 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 expertise?

Then 7 months later I dared to jot down a sequel to that publish during which I introduced 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) concerning AI nevertheless it introduced a lot more durable details to again its claims. The claims introduced by the authors have been primarily based 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 okay, the computational price scales by okay^9). With this, we mainly acquired an equation to estimate simply how a lot cash we’ll have to hold 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 expertise 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 record is infinite. Immense developments.
So, is AI slowing down? Was I proper or fallacious method again in 2021?
I believe I used to be each proper and fallacious.
My preliminary declare was backed-up by Jerome Pesenti who on the time was head of AI at Fb (the present head there now’s none aside 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 activity in a greater method… However clearly the price of progress will not be 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 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 take into accounts (and neither did he) was that Massive 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 keep up the big inflow of cash from different sources consistently coming into the market. Under are latest figures concerning investments within the discipline of Synthetic Intelligence:
- Anthropic, a direct rival of OpenAI, acquired at the least $1.75 billion this yr with an extra $4.75 billion out there 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 received $500 million for its concept to mix quantum sensors with AI,
- Mistral AI raised $113 million in June final yr regardless of it being solely 4 weeks outdated on the time and having no product in any respect to talk of. Loopy.
- and the record goes on…
Staggering quantities of cash. However the massive one is Microsoft who pumped US$10 billion into OpenAI in January this yr. That goes on prime 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). Massive 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 developments associated to AI. It’s produced by a crew of researchers and consultants from academia and trade. This yr the AI Index (launched this month) has been “probably the most complete up to now” with a staggering 502 pages. There are some extremely insightful graphs and knowledge 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. Be aware 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 offers a neat abstract:
Be aware the GPT-4 (out there 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 will not be slowing down, but. There nonetheless appears to be steam left within the trade. 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 recreation.
After all, the massive boys have huge reserves of cash so the race is on, for certain. We might hold going for some time like this. Nonetheless, it’s certainly honest to say as soon as once more that this sort of development is unsustainable. Sure, extra fashions will hold rising which are going to get higher and higher. Sure, an increasing number of cash shall be dropped into the kitty. However you may’t hold shifting to the best 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 way in which we do issues – I mentioned this matter in my earlier two posts).
The craziness that massive tech has dropped at this complete saga is thrilling and it has prolonged the lifetime of AI fairly considerably. Nonetheless, the truth that solely massive gamers are left now who’ve wealth at their disposal bigger than most nations on the planet is a telling signal. AI is slowing down.
(I’ll see you in three years’ time once more once I concede defeat and admit that I’ve been fallacious. I actually hope I’m as a result of I need this to maintain going. It’s been enjoyable.)
