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.

    There’s such a huge gap between what I read about GPT-5 online, versus the overwhelmingly disappointing results I get from it for both coding and general questions.

    I’m beginning to think we’re in the end stages of Dead Internet, where basically nothing you see online has any connection to reality.

      Well yeah, it’s a for-profit company. They exist solely to make money, that’s their entire goal.

      It’s almost all marketing and has been for a while. ChatGPT peaked with 4o (and 4.5 if you used their API), 4.1 was a step backwards despite them calling it an improvement, and 5 was another step backwards.

      They are not any closer to AGI, and we’re not going to see AGI from LLMs no matter how much they claim just how close we are to seeing AGI.

    For reference, this is roughly equivalent to playing a PS5 game for 4 minutes (based on their estimate) to 10 minutes (their upper bound)

    calulation

    source https://www.ecoenergygeek.com/ps5-power-consumption/

    Typical PS5 usage: 200 W

    TV: 27 W - 134 W → call it 60 W

    URI’s estimate: 18 Wh / 260 W → 4 minutes

    URI’s upper bound: 48 Wh / 260 W →10 minutes

      I was just thinking, in more affordable electric regions of the US that’s about $5 worth of electricity, per thousand requests. You’d tip a concierge $5 for most answers you get from Chat GPT (if they could provide them…) and the concierge is likely going to use that $5 to buy a gallon and a half of gasoline, which generates a whole lot more CO2 than the nuclear / hydro / solar mixed electrical generation, in reasonably priced electric regions of the US…

    The last 6 to 12 months of open models has pretty clearly shown you can substantially better results with the same model size or the same results with smaller model size. Eg Llama 3. 1 405B being basically equal to Llama 3.3 70B or R1-0528 being substantially better than R1. The little information available about GPT 5 suggests it uses mixture of experts and dynamic routing to different models, both of which can reduce computation cost dramatically. Additionally, simplifying the model catalogue from 9ish(?) to 3, when combined with their enormous traffic, will mean higher utilization of batch runs. Fuller batches run more efficiently on a per query basis.

    Basically they can’t know for sure.

    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.

      This figure is already not bad. 40 watt hours = 0.04kWh - you know kWh? That unit on your electric bill that is around $0.18 per kWh (and data centers tend to be in lower cost electric areas, closer to $0.11/kWh.) Still, 40Wh would register on your home electric bill at $0.0072, less than a penny. For comparison, an average suburban 4 ton AC unit draws 4kW - that 40Wh request? 1/100th of an hour of AC for your home, about 36 seconds of air conditioning. I don’t know that this article is making anybody “look bad” in terms of power used.

          AI models require a LOT of VRAM to run. Failing that they need some serious CPU power but it’ll be dog slow.

          A consumer model that is only a small fraction of the capability of the latest ChatGPT model would require at least a $2,000+ graphics card, if not more than one.

          Like I run a local LLM with a etc 5070TI and the best model I can run with that thing is good for like ingesting some text to generate tags and such but not a whole lot else.

              It’s horrendously slow, unusable imo. With the larger DeepSeek distilled models I tried that didn’t fit into VRAM you could easily wait 5 minutes until it was done writing its essay. Compared to just a few seconds when it does. Bit that’s with a RTX 3070 Ti, not something the average ChatGPT user has lying around probably.

              There are very small models that can run on mid range graphics cards and all, but it’s not something you’d look at and say “Yeah this does most of what chatGPT does”

              I have a model running on a gtx 1660 and I use it with Hoarder to parse articles and create a handful a tags for them and it’s not… great at that.

    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.

      For training yes, but during operation by this studies measure Deepseek actually has an even higher power draw, according to the article. Even models with more efficient programming use insane amounts of electricity

      This was higher than all other tested models, except for OpenAI’s o3 (25.35 Wh) and Deepseek’s R1 (20.90 Wh).

      BTW a lot of it seems to be just inefficient coding as Deepseek has shown.

      Kind of? Inefficient coding is definitely a part of it. But a large part is also just the iterative nature of how these algorithms operate. We might be able to improve that via code optimization a little bit. But without radically changing how these engines operates it won’t make a big difference.

      The scope of the data being used and trained on is probably a bigger issue. Which is why there’s been a push by some to move from LLMs to SLMs. We don’t need the model to be cluttered with information on geology, ancient history, cooking, software development, sports trivia, etc if it’s only going to be used for looking up stuff on music and musicians.

      But either way, there’s a big ‘diminishing returns’ factor to this right now that isn’t being appreciated. Typical human nature: give me that tiny boost in performance regardless of the cost, because I don’t have to deal with. It’s the same short-sighted shit that got us into this looming environmental crisis.

        It would only take one regulation to fix that:

        Datacenters that use liquid cooling must use closed loop systems.

        The reason they dont, and why they setup in the desert, is because water is incredibly cheap and energy to cool a closed loop system is expensive. So they use evaporative open loop systems.

      My guess would be that using a desktop computer to make the queries and read the results consumes more power than the LLM, at least in the case of quickly answering models.

      The expensive part is training a model but usage is most likely not sold at a loss, so it can’t use an unreasonable amount of energy.

      Instead of this ridiculous energy argument, we should focus on the fact that AI (and other products that money is thrown at) aren’t actually that useful but companies control the narrative. AI is particularly successful here with every CEO wanting in on it and people afraid it is so good it will end the world.

            I don’t think they can survive if they gatekeep and make it unaffordable to most people. There’s just not enough demand or revenue that can be generated from rich people asking for chatGPT to do their homework or pretend to be their friend. They need mass adoption to survive, which is why they’re trying to keep it artificially cheap in the first place.

            Why do you think they haven’t raised prices yet? They’re trying to make everyone use it and become reliant on it.

              Well, if they succeed, it’s because of efficiency and lowering costs. Second is how much the data and control is really worth.

              The big companies is not just developing LLM’s, so they might justify it with other kinds of AI that actually makes them alot of money, either trough the market or government contracts.

              But who knows. This is a very new technology. If they actually make a functioning personal assitant so good, that it’s inconvinient not to have it, it might work.

            As an example, this is today’s ProductHunt

            And yesterday’s was AI, and the day before that it was AI, but most of them are demonstrating little value with high valuations.

            LLMs will survive, likely improve into coordinator models that request data from SLMs and connect through MCP, but the investment bubble can’t sustain

            Technologies come and go, but often when a worldwide popular one vanishes, it’s because it got replaced with something else.

            So lets say we need LLM’s to go away. What should that be? Impossible to answer, I know, but that’s what it would take.

            We cant even get rid of Facebook and Twitter.

            BUT that being said. LLMs will be 100x more efficient at some point - like any other new technology. We are just not there yet.

              @themurphy @rigatti There is one difference … LLM’s can’t be more efficient there is an inherent limitation to the technology.

              https://blog.dshr.org/2021/03/internet-archive-storage.html

              In 2021 they used 200PB and they for sure didn’t make a copy of the complete internet. Now ask yourself if all this information without loosing informations can fit into a 1TB Model ?? ( Sidenote deepseek r1 is 404GB so not even 1TB ) … local llm’s usually < 16GB …

              This technology has been and will be never able to 100% replicate the original informations.

              It has a certain use ( Machine Learning has been used much longer already ) but not what people want it to be (imho).

        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.

      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”.

    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.

      That’s a terrible metric. By this providers that maximize hardware (and energy) use by having a queue of requests would be seen as having more energy use.

    Help me out here. What designates the “response” type? Someone asking it to make a picture? Write a 20 page paper? Code a small app?

      Response Type is decided by ChatGPTs new routing function based on your input. So yeah. Asking it to “think long and hard”, which I have seen people advocating for to get better results recently, will trigger the thinking model and waste more resources.

        So instead of just saying “thank you” I now have to say “think long and hard about how much this means to me”?

          Once it generates the response, there is a button you can click to make it use the reasoning model.

          Why they did it that way instead of giving users the option to just set the model that they want to use ahead of time boggles the mind. Surely it would be more efficient for them to chose a model if they want ahead of time, rather than generating something that’s going to be regenerated with the desired model instead.

          FFS, I have been using Claude to code, not only do you have to tell Claude to fix compilation errors, you have to point out when Claude says “it’s fixed” - “no, it’s not, the function you said you added is STILL missing.”

    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.

      Look at all the layoffs they’ve been able to implement with the mere threat that AI has taken their jobs. It’s very profitable, just not in a sustainable way. But sustainability isn’t the goal. Feudal state mindset in the populace is.
