    What is their angle with this?

    Surely SamA doesn’t actually think that they’ll more than 20x their compute in a few years? I’m sure the researchers there would love to do more research, with more compute, faster, but 20+x growth is not a practical expectation.

    Is the goal here to create a mad rush to build data centers, which should decrease their costs with more supply? Do they just want governments to step in and to help somehow? Is it part of marketing/hype? Is this trying to project confidence to investors on future revenue expectations?

      If their goal is to train say, a 100T model on the whole youtube dataset they will need 20000x more compute. And that would be my goal if I were him.

      • bix6 8 hours ago ago

        Why 20000x more compute? I thought they were at approx 1T with current compute?

        Edit: looked it up. 10k+ times more for training compute. Sheesh. Get the Dyson sphere ready lol.

              "At this point I think I know more about manufacturing than anyone currently alive on Earth."

              It's that dumbass at your work who thinks that solely because he landed a job that pays him more than their parents ever made combined in his early 20s he can school everyone on every topic imaginable, from nutrition to religion.

              Him and Elon makes way more than that dumbass so ego get inflated even more.

              I don't especially like Tucker Carlson, but I think the more screen time we'll give to this people with an open mic it's better for everyone to have a first hand experience of how detached from reality these people are.

                Absolutely right, and it's ubiquitous across organizations too.

                I've never met an executive I respect. They're all absolute experts at appearing competent.

        • kadushka 7 hours ago ago

          Mainly because global video data corpus is > 100k larger than global text corpus, so you will need to train much larger models for much longer (than current LLMs).

    • pram 7 hours ago ago

      Perceptually, it helps to take scrutiny off the current spend? It isn't a bubble if you can just scoff at $100 billion and say like" "thats pocket change, this will actually require 10 quadrillion dollars!!"

    • ants_everywhere 6 hours ago ago

      If they want to survive they need to outrun Google and have a differentiated service. Which as of now it's not clear that OpenAI will have a reason to exist in the near future with Anthropic and Google.

      They're likely betting on either training a model so big they can't be ignored or possibly focusing more B2B which means lots of compute to resell.

    • skywhopper 7 hours ago ago

      He needs 11 figures of cash injected as soon as possible. The people who can give it want a big return. Given the current losses, the only way to make the math right is to lie outrageously about what’s possible.

    • refulgentis 8 hours ago ago

      > Surely SamA doesn’t actually think that they’ll more than 20x their compute in a few years?

      He does, or at least, he believes if its plausible they should attempt to.

      We live in odd times. It sort of reminds me of Feb 2020. All you really needed to know was the Rt and rest was just math. Who knows if it'll matter or pencil out in a decade, but, it's completely reasonable at these growth rates and with the iron laws known to keep scaling.

      In the early days of Bitcoin, we would argue security models and laugh about Bitcoin mining taking some significant percentage of global power supply. It's been giving around 1% for a while now despite the supply falling off.

      I wouldn't put bets on what the outer limits for AI are going to be. However, it's a huge productivity boost across a huge range of workflows. Models are still making large gains as they become more sophisticated.

      If I had Sam Altman's access to other people's capital, I would be making large bets that it will keep growing.

  • Incipient 3 hours ago ago

    Is it just me, or does this extreme demand for compute imply they've realised the core tech is mostly stagnant, and needs compute to possibly scale towards anything AGI-like? (however unlikely that is).

    Too big to fail is the goal. If the world is powered by openai but it aint making a profit in 2028 they can just put their "were a utility like water" facemask on and get bailed out.

    • stevenwoo 7 hours ago ago

      At least in the USA, I think if consumers realized their power bills going up every year are tied to these new data centers, there would be more opposition to data centers going up politically. https://apnews.com/article/electricity-prices-data-centers-a... I don't know if the electricity markets work differently in other countries.

      • omcnoe 5 hours ago ago

        The US needs sufficient energy surplus to power industry. US energy production has been essentially flat for the past 25 years and the country has forgot how to bring new capacity online. Chinese energy production is up over 6x over the same period. China has more clean energy generation capacity today than their entire capacity a little over a decade ago.

        Instead of panicking about data center electricity usage we need to be worrying about getting back to a state where we regularly bring new (clean) generation capacity online.

      • MountDoom 6 hours ago ago

        Taxpayers subsidize data centers in many other ways. These are prestige projects for politicians, so they often get long-term tax breaks and other preferential treatment.

        I think it's part vanity, part a misunderstanding about the economic benefits of a datacenter (which are nearly nil, as they employ very few people and produce nothing for the local market), and part just a desire to score brownie points with wealthy corporations, which might mean donations, campaign support, or other perks for the politician who makes it happen.

      • fooker 3 hours ago ago

        It's correlated to be data centers, not tied to. That's an important difference.

        We could easily build ..say.. 10 nuclear reactors and halve the utility bills with amortization.

      • noosphr 6 hours ago ago

        The power bill going up is because the US, and the West in general, bet on renewables and a low energy future.

        Neither of those things turn out to be a good fit for the new economy. The only thing left for people who derided nuclear for the last 40 years is to hope this is a bubble that sends us back to the 17th century when it pops. Anything else means we have to invest trillions in nuclear right now.

        • DavidPiper 6 hours ago ago

          Genuine question from a non-American: What is "the new economy"?

          • noosphr 6 hours ago ago

            Malthusianism for computers.

            Moore's law is dead. The only way to increase compute is to increase the power we feed to computers. AI is just the shiniest example. Everything else will follow suit until electricity costs increase enough that it doesn't make sense to throw any more computation at it.

            Any country that doesn't have energy to spare will be in the position of countries which didn't have food to support armies before the industrial revolution.

            • fooker 3 hours ago ago

              Interesting point. I can see this could turn out to be true.

              If we needed, for example, 1000 TWH to power AI for a huge drone swarm but could not do it while China could, this would be problematic.

              It requires a future where MAD with nuclear weapons is obsolete though, with some futuristic new missile defense tech. I don't see that happening until some currently unknown physics makes it possible.

        • jimbob45 3 hours ago ago

          What’s your beef with solar? Both parties seem to like it just fine, despite it not covering as much of the total demand as anyone would like.

          • noosphr 14 minutes ago ago

            Both parties like it better because it turns the electricity market into another casino that lets you take billions from the parts of the economy that do things.

            I worked as a quant in the electric market. There wasn't a single dataset I saw where more renewables resulted in lower total costs for consumers.

        • Drblessing 6 hours ago ago

          The amount of money being invested in AI should've been invested into nuclear, both fusion and fission. The AI bubble will burst, but the energy bubble never bursts.

      When you square that with the total revenues of 6B in 1H.

      • roenxi 7 hours ago ago

        They haven't put ads in ChatGPT yet as far as I know. It doesn't really make sense to work off the raw revenue before they put the main revenue-raiser in. Search isn't a very impressive money maker either if we take AdWords out.

        • sverhagen 7 hours ago ago

          I have a subscription. Dang, who does every profit model have to involve ads?

          • fooker 3 hours ago ago

            Because not everyone wants to pay for a subscription, certainly not the 5 billion Asians in any reasonable numbers.

            There's a reason Google and Facebook run the tech world as we know it.

        • thereitgoes456 6 hours ago ago

          You and everyone else seem to assume on faith that OpenAI's ads revenue is going to dwarf their subscription revenue -- but you're being suckered. If you do the math, you'll find it's not nearly as clear-cut as you think.

          Not impossible, but not a given.

          • og_kalu 5 hours ago ago

            >If you do the math

            On the contrary the math makes it very clear. They need a free user ARPU of $11 to 12 per quarter to be profitable with billions to spare.

            That's a low bar to clear for a platform with 700M+ Weekly Active Users who are more personal with it than any Google search.

      > $16Bn in compute spend (rent) rising to $400bn in 4 years. Definitely not a bubble. ;)

      Just to put that in context, US GDP last year was about $30tn, and Apple's revenue was about $400bn. So Altman is saying he wants to spend around 1% of US GDP, or most of Apple's revenue, on compute alone in 2029. He's clearly using the "fire all your white collar employees" pitch deck at the very least, if not the "prepare to meet your Silicon God" one.

    • dgfitz 8 hours ago ago

      I also feel like there is a bubble.

      However, looking at it impartially, it seems to mean sama is planning on making more money. Which seems to conclude in ads are incoming.

      • ares623 8 hours ago ago

        We give a lot of shit when LLMs get lost in context, digging themselves deeper and deeper into illogical trains of thoughts.

        But is this sama doing the same thing. He CAN NOT stop and MUST NOT slow down. The slightest display of hesitation and doubt will make it all come crashing down.

        And everyone else is doing the same. It’s an international game of chicken.
