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 increasingly more advanced 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 expertise?

Then 7 months later I dared to write down a sequel to that put up wherein 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 but it surely introduced a lot more durable information to again its claims. The claims introduced by the authors had 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 value will increase exponentially by an element of 9 (i.e. to enhance efficiency by an element of okay, the computational value 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, Three years on. How have my opinion items fared after such a prolonged time (an eternity, in reality, 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 listing is infinite. Immense developments.
So, is AI slowing down? Was I proper or mistaken manner again in 2021?
I believe 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’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 clear up a broader job in a greater manner… However clearly the price of progress just isn’t 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 suppose in phrases of optimization, when it comes to value profit
Article for Wired.com, Dec 2019 [emphasis mine]
I agreed with him again then. What I didn’t think about (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 massive inflow of cash from different sources consistently getting into the market. Under are current figures concerning investments within the subject of Synthetic Intelligence:
- Anthropic, a direct rival of OpenAI, acquired at the least $1.75 billion this yr with an additional $4.75 billion accessible within the close to future,
- Inflection AI raised $1.Three billion for its very personal chatbot known 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 yr regardless of it being solely Four weeks outdated on the time and having no product in any respect to talk of. Loopy.
- and the listing goes on…
Staggering quantities of cash. However the huge one is Microsoft who pumped US$10 billion into OpenAI in January this yr. 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 accordance with Jerome Pesenti (and me). Massive Tech can, it appears!
Let’s take 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 tendencies associated to AI. It’s produced by a workforce of researchers and consultants from academia and business. This yr the AI Index (launched this month) has been “essentially 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. Observe that the y-axis (coaching value) is in logarithmic scale.
It’s clear that newer fashions are costing increasingly more. Far more (contemplating the log scale).
For precise coaching value 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-Four was de-facto developed by Microsoft. Is smart.
The place does this depart us? Contemplating the newest product releases, it looks as if AI just isn’t 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 large boys left within the sport.
In fact, the large boys have huge reserves of cash so the race is on, for certain. We might maintain going for some time like this. Nevertheless, it’s certainly honest to say as soon as once more that this sort of progress is unsustainable. Sure, extra fashions will maintain rising which might be going to get higher and higher. Sure, increasingly more cash will likely be dropped into the kitty. However you possibly can’t maintain shifting to the proper of these graphs indefinitely. The equation nonetheless holds true that with the rise in efficiency of a DL mannequin, the computational value will increase exponentially. Returns on investments will begin to diminish (until 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 huge tech has delivered to this complete saga is thrilling and it has prolonged the lifetime of AI fairly considerably. Nevertheless, the truth that solely huge gamers are left now who’ve wealth at their disposal bigger than most international locations on this 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 mistaken. I really hope I’m as a result of I need this to maintain going. It’s been enjoyable.)
