    Chinese AI companies are free to use any Nvidia GPU they want as long as the GPU is not physically located within China. It is entirely consistent with US export controls for Chinese AI companies to remotely use GPUs located in Singapore or Malaysia.

    “In facilities across the region, Megaspeed rents Nvidia chips to Chinese tech giants such as Alibaba, an arrangement that does not violate current US export control regulations.” See [1].

      Literally my first thought. Noone can stop them from training in data centers that are located elsewhere. It's not like some military hardware that needs to be physically shipped to China for them to make use of it. In fact why would they bother with Chinese compute providers if those are limited because of GPU export controls? They knew this for a long time and probably have been knocking on the door of providers in other countries for a while. Heck, they could be training inside the US. They already distribute their open model weights from the US.

        The US definitely has the power to stop most of it. It just looks like the executive branch doesn’t yet have the legal authority to do it, but it’s in an advanced legislative state.

        • flowerlad a day ago

          How are you going to monitor who is logging into a system, or who a job is being run for? If you want that level of control the machines should not be exported at all.

          • vikramkr 12 hours ago

            Datacenters are very large and not very mobile and full of very expensive export controlled equipment and training runs are large expensive contracts. This is not exactly a difficult context to enforce KYC rules in

          • cowlevel 17 hours ago

            Same way they do for Iran: if they catch you providing services to someone in Iran, they send you to jail for life. And they monitor all financial transactions so they'll notice.

              They can do that to Americans. Harder for the rest of the world. How is the US going to monitor CIPS payments? How will they jail someone who never goes to the US? Just how much global jurisdiction is the US claiming?

              • throwaway2037 15 hours ago

                In practice, the key ways that the US exerts influence outside of its own borders: (1) Sanction the company, which means any other company that does business with that company can also be sanctioned. (2) If enough companies are evading sanctions in a single country or the govt is helping those companies, then threaten to cut the country from USD settlement with the Federal Reserve, e.g., no USD FX allowed. That pretty much screws most economies. The "long arm" of the US govt is very, very, very long!

                To be clear: I am not saying any of this is fair (or legal); I am only explaining how it works.

                The same way they "jail" UN-appointed judges that go against their masters' interests: de-platform them from all US-controlled payment and software platforms.

                • graemep 10 hours ago

                  That is not jail.

                  if you are referring to people at the ICC, they are cut off from US services, but that is a long way from being in jail.

                      Yes, they can. They cannot buy things from Amazon or book through booking.com, as that French judge said, but they can do things that do not require American systems. Do you have any evidence they cannot have phones? What stops they shopping in person? Or booking directly with a hotel?

          • awesome_dude 20 hours ago

            The same way that SAAS and IAAS (etc) providers do now for citizens of other countries under sanctions - IPs, Credit Cards

            • mahkeiro 20 hours ago

              So another company in Asia is going to execute the batch and send the result back to China. And you can add as many indirection levels as you like. This is going to be impossible to track.

              • vikramkr 12 hours ago

                You'd just invert it. Make it so you have to be approved under export controls as a customer like they were gonna do for mythos (and like how mythos sort of still works) and make it an allowlist instead of a denylist

              • awesome_dude 18 hours ago

                If that company is acting in defiance of sanctions, like any other company that acts as a middleman to circumvent sanctions, and it is caught, it will face severe consequences.

                There's no gotcha here, companies the world over could just ignore any sanctions they wanted, and some try to, but they do so knowing they themselves are (potentially) breaking local and international laws.

                You might have well asked "what if a company helps you by importing contraband instead of you doing it directly"

                • Qiu_Zhanxuan 17 hours ago

                  None of them are breaking local and international laws by doing so, unless a country's ruling says other countries laws supersede their own

                  • awesome_dude 17 hours ago

                    One of the key reasons that a country like the USA can enforce sanctions is that it can tell other countries that if their companies/citizens/etc break the sanctions, then the USA will put restrictions on those countries ability to trade with the USA, which is why only a few countries will trade with Iran, North Korea, and Russia

                    • nmfisher 12 hours ago

                      At some point those countries will also tire of the USA trying to tell them what to do and will tell the USA politely to fuck off. This is basically what India did with US sanctions on Russia and Iran.

                      Given the USA has completely torched its reputation amongst allies in the space of a year, I would expect this to happen more often.

                    • throwaway2037 15 hours ago

                      Exactly right. The term I use is "economic network effect".

                      Does anyone know why does the US allows Canada to trade with Cuba? That one always stood out to me as a bit odd. My guess: Canada is the largest trade partner with the US, so the US probably has more to lose by sanctioning Canada.

                  • cowlevel 17 hours ago

                    Yes, that's called a treaty, or a trade agreement. Remember all the fuss about Investor/State Dispute Settlement clauses? Most countries have them with each other by now.

                    • awesome_dude 17 hours ago

                      To add to this, if the provider suspects that a customer is facilitating sanction busting, or could reasonably be expected to have foreseen it, that's enough for a discussion with lawyers...

                • LtWorf 17 hours ago

                  Lol what consequences? Such shell companies can appear by the thousands every hour. Even if you ban 2 or 3 it doesn't matter.

                    Funny, sanctions have successfully applied to countries such as Russia, Iran, etc for decades...

                    They do try workarounds, and when those are caught there are consequences

                    You can sit back down now.

                    Edit: Is there going to be more "laws can be broken so let's not bother" arguments, because that's lame and boring

                      > sanctions have successfully applied to countries such as Russia, Iran, etc for decades.

                      Largely because other countries are willing to go along with it, and to the extent they are willing to do so.

                      Even NATO countries import Russian gas. The UK rolled back sanctions on Russia to import diesel earlier this year. Most of the rest of the world did not impose effective sanctions and lots of people trade with them (including huge economies like China).

                      The rest of the world is to dependent on China to want to get involved. The US might succeed in the current administrations attempt to split the world into new cold war spheres of influence (because people are scared of China too) but its not going to be easy, it will be painful, and its not going to get many countries to completely agree to what the US wants.

                            Not sure if you understand this, but nobody said they were, but, if you have a quick browse of the threads, it has been pointed out how they ensure cooperation from other countries.

                            The truth is you've come here with a mindset based on a political ideology and that's blinded you to the objective discussion being held.

                            Further, the fact that I keep pointing out your argument is the same as the one where people claim laws are of no use because they are routinely broken does not mean anything other than I am telling you how pathetic your claim is.

          how would that work?

    • cowlevel 17 hours ago

      They're also free to use Nvidia GPUs physically located in China. However, customs and border enforcement will try to stop them from moving GPUs physically located outside China to physical locations inside China. However, if they can bypass that, they can use the GPU.

          • jonathanstrange 18 hours ago

            The US could impose secondary sanctions to close the loophole, or pressure these countries behind closed doors to not allow these data center uses. Since the only goal of the export restrictions is to hamper Chinese AI efforts, that would be a logical step. If there is one thing that is certain then it's that the current US administration doesn't care at all about open trade and international trade agreements.

    • modeless a day ago

      The method seems sound and the findings correct. But I think many are missing that (as the research itself says) this doesn't prove any illegal behavior. It's perfectly legal for Chinese companies to train models on GPUs that they rent outside of China. It's also legal for companies to buy GPUs and install them in Malaysia with the intention of renting them to Chinese companies.

      There isn't even an allegation that the Chinese companies lied about this. They simply didn't disclose which chips were used. In all cases where they did disclose the training chips, this research found the disclosures to be accurate.

      • adrian_b 15 hours ago

        The small print in TFA states the many limitations of their method, i.e. that it actually provides no evidence about which GPUs were really used for training, and much less about who was their owner and where they were located.

        The method just strongly suggests that the initial values of the weights, before starting training, were generated with the NVIDIA cuRAND library on a Blackwell GPU (or on an AMD GPU, where the NVIDIA library is emulated for compatibility).

        The training might have been done with thousands of GPUs of other types. It is plausible that the GPUs used for training or at least a part of them may have been of the same type with the one used for initializing the model, but it is not proven in any way.

        A scenario that matches what is reported in the article, but in which there is only a single Blackwell GPU involved, is if the LLM was intialized on the workstation of some lead developer, who had the privilege to use the best GPU they had, and then it was transferred to a server cluster for training, where other kinds of GPUs were used.

        Now that this has been published, it would be very simple in the future for any Chinese AI company to avoid this "fingerprinting", by just using a different PRNG, instead of cuRAND.

        • modeless 9 hours ago

          Yes it's simple to avoid this fingerprinting now that people know about it, but nobody knew about it before. I don't believe people are casually transferring snapshots between chip architectures without a really good reason, either. It's hard enough to coordinate these training runs without involving multiple chip architectures in a single run.

      • RobertoG 18 hours ago

        Does 'legal' an 'illegal' apply here? Surely, the USA legal system only apply in the USA?

        • modeless 10 hours ago

          'Legal' and 'illegal' apply to Nvidia or other US companies facilitating these activities. Perfectly legal for Nvidia to supply GPUs to be rented by Chinese companies, or for Oracle to build datacenters for Chinese companies to rent, as long as they are installed outside of China.

        • cowlevel 17 hours ago

          Their government is not really the type to violently take over other countries and impose their laws. Taiwan is a special case because they see it as a rebel state on their own land. The rest of us are probably better off with China being the top superpower than Trump's America.

            > Their government is not really the type to violently take over other countries and impose their laws.

            Taiwan would like a word. Taiwanese govt was the original government in China before CCP violently took over in the aftermath of WW2 with help from the Soviet Union.

            China was also involved in destabilizing Vietnam by backing the communists and then after having a fall out with the communists there, proceeded to engage in border conflicts for almost two decades before normalizing relations.

            China hasn't lifted a finger for Ukraine. It hasn't lifted a finger for Venezuela. It hasn't lifted a finger for Iran. Nobody knows what China's long term intentions are or how China will change after Xi Jinping's reign.

    > We recover traces of the models’ initial values, and then search for the hardware configurations and initial configurations that reproduce them

    From my (very cursory, naive, layman's) glance at the summary, they're identifying and tracing some characteristics that specific hardware imparts into a model's initialized weights. But then concluding that this indicates the models were also "trained on" that same hardware.

    But is that a valid assumption? Is it possible that a model was initialized on one system configuration, while the bulk of the training was performed on another?

    In fact, it would seem reasonable for the "okay, I'm setting up this new model on my workstation, prepping it for training next month" pipeline step to be far removed from the "okay, now deploy the [initialized, but not yet trained] model across our giant fleet of beefy training machines".

  • basiccalendar74 a day ago

    as the post mentions, the models could have been trained on 1. GPUs within China or 2. GPUs outside China for example datacenters in Singapore.

    The 2nd option is perfectly legal and allowed by US government.

    • cowlevel 17 hours ago

      The 1st option is also perfectly legal and allowed by the US government. Only the export of GPUs is illegal, and only sometimes.

    • dcrazy a day ago

      Is the U.S. government OK with this if the money to buy those GPUs and run inference on them comes from Chinese companies?

      • seanmcdirmid a day ago

        yes. The USA hasn't force an embargo on China to other countries (e.g. by threatening to cut off Swift access). We aren't technically at war either, so its highly unlikely that the US would go that far.

        What is surprising, I guess, is that the US allows GPUs to be exported at all to most countries. Since...as long as they are exported to a country that is friendly to china (which is basically most countries on the planet), China has access to GPUs on which to train with, making GPU purchasing restrictions mainly symbolic.

        • HDThoreaun 21 hours ago

          They dont need to threaten other countries, they can just pass a law saying that anyone anywhere in the world selling or renting gpus to chinese companies is committing a crime. Then they can sanction any company that does it anyway and that makes it a crime for any american company to sell gpus to that company. There have already been quite a few criminal cases around the export ban.

            That would be unenforceable though knowing American arrogance they would definitely try. It’s like China trying to stop their rare earths from going to American uses by requiring all companies that import them to track their usage.

    Yeah makes sense. They are in transition. This article doesn't really tell us anything new (or interesting). There's nothing wrong w Chinese labs using GPUs that are already in the country. An export ban just means reduced import of new GPUs

    What if the gov tolerated gpu exports on purpose?

    Black & grey market devices marked up many times cost buyers heavily, while still suppressing motivation to develop sovereignty.

    If nvidia selling to China tolerated for the realpolitik and gets undone by incoming powers to create an appearance of change, is it really the right thing to do? Is it the smart thing to do?

    It's an interesting thought experiment, though, we will probably never know.

      Why on earth would that be suppressing motivation to develop sovereignty? The whole thing makes developing sovereignty an existential priority. When one critical part of your AI technology stack is subject to whims of your adversary, it's not really fully your AI technology stack. Today they turn the tap partially on, but only unofficially, tomorrow they'll shut it off. Time to buy your own tap.

        I don't know the exact reason, but all empirical evidence shows that it does. E.g. the whole of Europe still using Microsoft because they can, even though bits and pieces get cut off (like the ICC). If Microsoft cut off the whole of Europe, then Microsoft wouldn't have power over them any more.

          Microsoft's days in many EU countries' government departments are numbered regardless of what Microsoft does.

    I have run some large open models on neoclouds and the KYC has been minimal, even if the USG stops all GPU exports it will be extremely difficult to crack down on Chinese renting GPUs on Western servers.

    There will be a black market of renting IDs to KYC and gain access to the chips, and then the hosts will monitor their servers for what is being trained, it will be a cat and mouse game.

    We are headed for an increasingly unfree computation landscape and the politicians are going to make demands that will be hard to deliver.

  • stratos123 12 hours ago

    Weird detail: some of these results are based on initial patterns in weights surviving through training. But isn't muon, which is used for many of these models, well-known to be able to consistently erase patterns in weights, unlike previous optimizers [1]?

    This doesn't really call the overall results of the report in the question (the strongest finding is the perfectly matching weights for dead-weight rows which weren't touched by an optimizer at all), but it does suggest that the explanation in the twitter thread[2] of how this works is way too simplistic. Are the patterns in question somehow "special" and not erasable even with muon?

      • AnthonyMouse a day ago

        > Simply banning things causes the price to go up. That alone is good enough to motivate the policy decision.

        No twice.

        First, banning them doesn't necessarily even make the price go up. If all you have to do to get the product is put someone else's name on the form, that raises the price by a number that rounds to zero. It probably costs your own companies more in bureaucracy and paperwork to try to enforce the pointless rules than it costs the other one to put a different name on the form.

        Second, suppose it actually worked somehow. What happens then? The other country pays the higher price temporarily while throwing out some big government subsidies to develop a domestic version of the technology. Soon your own companies have a new foreign competitor in the world market which is receiving large government subsidies.

        Export controls are a failed policy.

        This may work when its against an smaller. When deployed agianst a (near) peer - there usually isn't a price to high for a field of national security interest. China could get all the GPUs it wants / the US could get all the rare-earth magnets it wants over the objections of the other country.

            That's implicit in "there's no price too high". However higher the price is, the difference is still a rounding error when your budget is trillions of dollars.

            I present this short-form documentary — or animated infographic, if you will — on how much governments are prudent in saving money in areas considered of vital national interests, denominated in GPUs instead of dollars: https://www.youtube.com/shorts/F6jMsMBVB34

      Export controls inherently raise the cost of doing business with parties you don't like, the other party has to either invest more resources acquiring them, or make the decision to forego acquiring them. The grey market exists precisely because there's an opportunity to exploit this for profit. At the end of the day, when these effects of these export controls are discussed, they usually seem to revolve around export controls setting a specific program or effort back by a span of months, not in stopping a specific commodity from accessing another market whatsoever (excepting some hyper-specific components).

  • yumraj a day ago

    Not doubting that they have access to these.

    But, could the fingerprints be due to distillation from Blackwell trained models rather than training?

    • taylorfinley 19 hours ago

      Weights start as random values generated from a seed. Pytorch uses however many cores are available on the architecture to write out the initial values in parallel, so each seed + architecture pair has a particular signature. If I understand Will's technique correctly he's basically made a rainbow table of initial weight states. Training alters the initial weights, but if you find one seed + architecture pair that vastly more-closely matches the trained weights, you can infer it must have been the source of the initial weights.

      Distillation might shape the weights similarly in some way to the source model, but that would come from the signal, not the noise. I think it would be very surprising if the initial untrained weights were encoded with any fidelity into the outputs such that training another randomly-initialized set of weights (likely of completely different size and shape) on them could leave a signature of the source model's initial state, does that make sense?

    • Tostino a day ago

      Not seeing how that could happen since all the "distillation" attacks i've seen are just token level, not logprob level, and definitely not vector level. So, I don't see how that could be the case.

But obviously there are more people who are more knowledgeable on this can give their perspectives here.

    • adrian_b 14 hours ago

      They match the pseudo-random generator from the NVIDIA library cuRAND.

      AMD has a library that emulates it, for compatibility.

      Their methodology is interesting, but it only proves access to a single Blackwell GPU, which would have been sufficient for initializing an LLM with random values, before the start of its training.

      There is no evidence whatsoever about which GPUs were used for training, except the supposition that if they had access to 1 Blackwell, they might have had access to more of them. Such a supposition may be justified about the number of cockroaches in a kitchen, but less so about the components of a training cluster, which might be heterogeneous.

      The LLM could have been initialized on the workstation of a developer, before being transferred to a server cluster, for training.
