The University of Rhode Island's AI lab estimates that GPT-5 averages just over 18 Wh per query, so putting all of ChatGPT's reported 2.5 billion requests a day through the model could see energy usage as high as 45 GWh.
A daily energy use of 45 GWh is enormous. A typical modern nuclear power plant produces between 1 and 1.6 GW of electricity per reactor per hour, so data centers running OpenAI's GPT-5 at 18 Wh per query could require the power equivalent of two to three nuclear power reactors, an amount that could be enough to power a small country.
It takes less energy to dry a full load of clothes

It will not go away at this point. Too many daily users already, who uses it for study, work, chatting, looking things up.
If not OpenAI, it will be another service.
Those same things were said about hundreds of other technologies that no longer exist in any meaningful sense. Current usage of a technology, which in this specific case I would argue is largely frivolous anyway, is not an accurate indicator of future usage.

Can you give some examples of those technologies? I'd be interested in how many weren't replaced with something more efficient or convenient.

This bubble needs to pop, the sooner the better.

but they are merely doing it to defend AI.
No they're not, you can agree the research is garbage without defending AI. It literally assumes everything. GPT5 could be using eight times the power. It could be using half the power. It could be using a quadrillion times the power. Nobody knows, because they keep it secret.
It’s highly unlikely they reduced power usage—one of the most consistent criticisms of LLM and image generation—without advertising it.

I have an extreme dislike for OpenAI, Altman, and people like him, but the reasoning behind this article is just stuff some guy has pulled from his backside. There's no facts here, it's just "I believe XYX" with nothing to back it up.
We don't need to make up nonsense about the LLM bubble. There's plenty of valid enough criticisms as is.
By circulating a dumb figure like this, all you're doing is granting OpenAI the power to come out and say "actually, it only uses X amount of power. We're so great!", where X is a figure that on its own would seem bad, but compared to this inflated figure sounds great. Don't hand these shitty companies a marketing win.

40 watt-hours? That's the energy usage of a very small laptop.

It's highly unlikely they would bring more attention to one of the biggest issues AI is causing even if they did make it slightly better

Bit of a clickbait. We can't really say it without more info.
But it's important to point out that the lab's test methodology is far from ideal.
The team measured GPT-5’s power consumption by combining two key factors: how long the model took to respond to a given request, and the estimated average power draw of the hardware running it.
What we do know is that the price went down. So this could be a strong indication the model is, in fact, more energy efficient. At least a stronger indicator than response time.

I think AI power usage has an upside. No amount of hype can pay the light bill.
AI is either going to be the most valuable tech in history, or it's going to be a giant pile of ash that used to be VC capital.
That capital was ash earlier this year. The latest $40 Billion-with-a-B financing round is just a temporary holdover until they can raise more fuel. And they already burned through Microsoft, who apparently got what they wanted and are all “see ya”.

How the hell are they going to sustain the expense to power that? Setting aside the environmental catastrophe that this kind of "AI" entails, they're just not very profitable.
Not just”not profitable”, they don’t make any money at all. Loss only.

Coordinated SLM governors that can redirect queries to the appropriate SLM seems like a good solution.

Isnt it just worse than 4 tho? If they didnt make it cheaper, nobody would pay...

That "not profitable" label should be taken with a grain of salt. Startups will do all the creative accounting they can in order to maintain that label. After all, don't have to pay taxes on negative profits.
In the end, it still means their losses are greater than their profits.
They've still got taxes they need to pay, too - things like payroll taxes, real estate taxes, etc.
-
That’s not what I’m saying. They’ve all but outright said they’re unprofitable.
But revenue is increasing. Now, if it stops increasing like they’ve “leveled out”, that is a problem.
Hence it’s a stretch to assume they would decrease costs for a more expensive model since that would basically pop their bubble well before 2029.
Revenue is increasing, but according to their own estimates, it has to increase 10x in order for them to become profitable.

And most importantly the Pandora box has been opened for deep perfect scams and illegal usage. Nobody will put it in the box again, because even if everyone agreed to make it illegal everywhere it's already too late.

Well over the course of an hot or two, but it's correct that a dryer run even with heat pump is significantly more than 40wh

Imagine if you had to empty your whole laptop battery every time you had to generate a 20 lines response that may not even be correct... That'll end up consuming power really fast.

That's alright. When they've got a generation of people who can't even hold a conversation without it, let alone do a job, that price increase will drop that energy use pretty rapidly.

I don't care how rough the estimate is, LLMs are using insane amounts of power, and the message I'm getting here is that the newest incarnation uses even more.
BTW a lot of it seems to be just inefficient coding as Deepseek has shown.
Also don't forget how people like wasting resources by asking questions like "what's the weather today".
