The massive computer clusters powering artificial intelligence consume vast quantities to answer the world’s queries, but how is Big Tech redressing the balance?
Writing a 100-word email using ChatGPT (GPT-4, latest model) consumes 1 x 500ml bottle of water It uses 140Wh of energy, enough for 7 full charges of an iPhone Pro Max
Hah! Haha! Hahahaahah! Ties well with this one news article that I glimpsed that claims that by 2030 the need for fresh water will be 140% of the world's freshwater reserves. Infinite growth forever!
I'm sure I'm missing out, but i have no interest in using chatbots and other LLMs etc. It floors me to see how much attention they get though, how much resources are being dumped into their development and use. Nuclear plants being reopened for the sake of AI?!!
I also assume there's a lot of things they're capable of that could be huge for science, and there's likely lots of big things happening behind closed doors that we're yet to see in the coming years. I know it's not all just chatbots.
The way this article strikes me though, is that it's pretty much just wasting resources for parlor-game level output. I don't know if i like the idea of people giving up their ability to write a basic letter or essay, not that my opinion on the matter is gonna change anything obviously 😅
Think of it like this: rich people accumulate more wealth by paying fewer people to accomplish more work faster, so it's worth burning through the worlds resources at breakneck speed to help the richies out, right?
It's possible to run an LLM on a moderately-powered gaming PC (even a Steam Deck).
Those consume power in the range of a few hundred watts and they can generate replies in a seconds, or maybe a minute or so. Power use throttles down when not actually working.
That means a home pc could generate dozens of email-sized texts an hour using a few hundred watt-hours.
I think that the article is missing some factor, such as how many parallel users the racks they're discussing can support.
And any other processing and augmentation being performed. System prompts and other things that are bloating the token size ...etc never mind the fact that you're getting a response almost immediately for something that an at home GPU cluster (not casual PC) would struggle with for many minutes, this isn't always a linear scale for power consumption.
You are also ignoring the realities of a data center. Where the device power usage isn't the only power consumption of the location, cooling must be taken into consideration as well. Redundant power switching also comes with a percentage loss in transmission efficiency which adds to power consumption and heat dispersion requirements.
It's true, I don't know how large the models are that are being accessed in data centers. Although if the article's estimate is correct, it's sad that such excessively-demanding models are always being used for use-cases that could often be handled with much lower power usage.
That's what I always thought when reading this and other articles about the estimated power consumption of GPT-4.
Run a decent 7B LLM on consumer hardware like the steam deck and you got your e-mail in a minute with the fans barely spinning up.
Then I read that GPT-4 is supposedly a 1760B model. (https://en.m.wikipedia.org/wiki/GPT-4#Background)
I don't know how energy usage would scale with model size exactly, but I'd consider it plausible that we are talking orders of magnitude above the typical local LLM.
considering that the email by the local LLM will be good enough 99% of the time, GPT may just be horribly inefficient, in order to score higher in some synthetic benchmarks?
The study that suggests 10-50 interactions with ChatGPT evaporates a whole bottle of water, doesn't account for the fact that cooling systems are enclosed....
...and that "study" is based on a bunch of assumptions, which include evaporation from local power plants, as well as the entire buildings GPT's servers are located in. It does this as if one user is served at a time, and the organizations involved (such as microsoft) do nothing BUT serve one use at a time. So the "study" (which isn't peer reviewed and never got published) pretends those buildings don't also serve bing, or windows, or all the other functions microsoft is involved with. It instead assumes whole buildings at microsoft are dedicated to serving just one user of ChatGPT at a time.
It also includes the manufacture of all the serve and graphics cards equipment, even though the former was used before ChatGPT, and will be used for other things as well... and the latter is only used in training.
It's completely junk. Worthless. Even uses a click bait title, and keeps talking about "the secret water foot print" as if it's uncovering some conspiracy. It's bunk science.
P.S It also doesn't seem to understand that the bulk of GPT's training was a one time cost, paid in 2021, with one smaller update in 2023.
I think there's probably something wrong with the math around per-response water consumption, but it is true that evaporative cooling consumes potable water, in that the water cannot be reused until it cycles through the atmosphere and is recaptured from precipitation, same way you consume water by drinking and pissing it out, or agriculture consumes it for growing things. Fresh water usage is a major concern and bottleneck, especially with climate change. With the average data centre using 300k gallons of water per day, and Google's entire portfolio using 5bn gallons per day, it's not nothing.
kW is a unit of instantaneous power; kW/s makes no sense. Note how multiplying that by seconds would cancel time out and return you power again instead of energy. You got there in the end, though.
Mark my words: generative "AI" is the tech bubble of all tech bubbles.
It's an infinite supply of "content" in a world of finite demand. While fast, it is incredibly inefficient at creating anything, often including things with dubious quality at best. And finally, there seems to be very little consumer interest in paid-for, commercial generative AI services. A niche group of people are happy to use generative AI while it's available for free, but once companies start charging for access to services and datasets, the number of people who are interested in paying for it will obviously be significantly smaller.
Last I checked there was more than a TRILLION dollars of investment into generative AI across the US economy, with practically zero evidence of genuinely profitable business models that could ever lead to any return on investment. The entire thing is a giant money pit, and I don't see any way in which someone doesn't get left holding the $1,000,000,000,000 generative AI bag.
Why does the article make it sound like cooling a data center results in constant water loss? Is this not a closed loop system?
I’m imagining a giant reservoir heat sink that runs throughout a complex to pull heat out of the surrounding environment where some liquid evaporates and needs to be replenished. But first of all we have more efficient liquid coolants, and second that would be a very lazy solution.
I wonder if they’ve considered geothermal for new data centers. You can run a geothermal loop in reverse and use the earth as a giant heat sink. It’s not water in the loop, it’s refrigerant, and it only needs to be replaced when you find the efficiency dropping, which can take decades.
Evaporative coolers save a ton of energy compared to refrigerator cycle closed loop systems. Like a swamp cooler, the hot liquid that comes from cooling the server is exposed to the atmosphere and enough evaporates off to cool the liquid by a decent percentage, then it's refrigerated before going back into the servers.
Data centre near me is using it and the fire service is used to be being called by people concerned the huge clouds of water vapor are smoke
It is a closed loop, but the paper treats it as if it's an open loop, and counts all water use for the building, as well as all the water that went into creating any equipment used.... and the water that escapes power plants in powering the buildings.... it also includes any other buildings that might house related services. Here is the original "study" which is about what maths could be done given the above assumptions:
In short, it has nothing to do with reality, and is more just an attempt at the authors to get their names out there (on bad science that the media is interested in publicizing for click bait reasons).
It highly depends on every data center, but it is very likely that they do use municipal water for cooling. Mainting a Reservoir is extremely expensive for the amount of thermal mass it requires, these things kick off HEAT.
I don't know why they aren't using reclaimed water from treatment plants. I don't see why potable water is necessary as long as the substitute isn't corrosive, but I might be missing something here.
I have read the comments here and all I understand from my small brain is that, because we are using bigger models which are online, for simple tasks, this huge unnecessary power consumption is happening.
So, can the on-device NPUs we are getting on flagship mobile phones solve these problems, as we can do most of those simple tasks offline on-device?
Yes, kind of… when those businesses making money out of the subscriptions are willing to ship with the OS for free which something only Apple has the luxury to do instead of OpenAI who doesn’t ship hardware or software (like Windows) beyond an app that’s less than 100MB. Servers would still be needed but not for general cases like help me solve this math or translation. Stable Diffusion or Flux is one example where you only need the connection to internet when downloading a certain model like you wouldn’t necessarily want to download every kind of game in the world when the intention is to play games arises.
You don't speak for the entire human race friendo. You don't get to decide what happens to us, and thank God. You seem too emotional and selfish to be any good at leadership.
• AI is ruining the environment and has yet to show any positive reason for it
• AI is taking jobs from people
• AI is destroying our art and our entertainment
But according to you…. I’m selfish for wanting to stop it.
And where do you get the idea that I’m being to emotional? Is it just that you thought it would help you by removing any validation from my statement?
How about this:
YOU don’t get to speak for me, friendo. You don’t get to decide if I’m emotional. And thank god. You seem too ignorant to be any good at psychological diagnoses.
it won't if you don't force it to. that's like saying companies will pollute less if you give them enough time. no, you have to grab their balls and force them to do it.
Until it does, we shouldn't exacerbate the climate and resource issues we already have by blindly buying into the hype and building more and larger corporate-scale power gluttons to produce even more heat than we're already dealing with.
"AI" has potential, ideas like machine assistance with writing letters and improving security by augmenting human alertness are all nice. Unfortunately, it also has destructive potential for things like surveillance, even deadlier weapons or accelerating the wealth extraction of those with the capital to invest in building aforementioned power gluttons.
Additionally, it risks misuse and overreliance, which is particularly dangerous in the current stage where it can't entirely replace humans (yet), the issues of which may not immediately become apparent until they do damage.
If and until the abilities of AI reach the point where they can compensate tech illiteracy and we no longer need to worry about the exorbitant heat production, it shouldn't be deployed at scale at all, and even then its use needs to be scrutinised, regulated and that regulation is appropriately enforced (which basically requires significant social and political change, so good luck).
Am I going insane? As far as I know cooling with water doesn’t consume the water, it just cycles through the system again. If anyone knows otherwise PLEASE tell me.
Industrial HVAC systems use water towers to cool the hot side of system.
The method relies on physics of evaporative cooling to reduce temperatures of the water. The process requires water to be absorbed by atmosphere, to drive the cooling effect.
(Lower the humidity, the higher the cooling efficiency is, as the air as greater potential to absorb and hold moisture).
The method is somewhat similar to power station cooling towers. Or even swamp coolers.
(An odd example would be, experimental PC water cooling builds with 'bong coolers', which are evaporative coolers, built from drainage pipes)
