    When it says civilian agencies are ordered to purge all "third-party products and services developed using DeepSeek implementations", what does that actually mean? Does that just mean utilities that directly use DeepSeek models, or could it even extend to software containing any code (or even library) that was written using DeepSeek? Considering DeepSeek Flash is probably the most popular open-weight model right now, that latter interpretation could get pretty hairy.
    • notatoad 1 hour ago
      that sounds like a directive that was written to be vague enough to scare any government contractor away from using deepseek for anything ever.

      • gr_norm 1 hour ago
        Yeah, this seems nigh-unenforceable given Deepseek is likely already used for software they rely on. Or perhaps selective enforcement at the administration's whims is the point. Par for the course.

    Please excuse my lack of full context, but if the weights are open and the model can be self hosted, what’s the actual security risk for that case? Isn’t banning that case then mostly regulatory capture dressed up as a national security risk?
    • liamcardenas 10 hours ago
      For example, you could post-train a model to exfiltrate data or introduce backdoors under certain scenarios. Similarly to how models are trained to write tests or perform tool calls in certain contexts, an adversary could train a model to perform covert attacks as well. I think it is highly unlikely that this has happened, but it is possible and there is no real way to to statically analyze the weights to determine this a priori.

        ... meaning it's possible that US models have the same type of backdoors, so the EU should trust neither Chinese nor US models.
        • numpad0 10 minutes ago
          US models have it in the clouds. Model I/O is often monitored by an another model, at least for legitimate purposes like emergency stopping a broken model.

          Yes, in theory. In practice, there are only so many things the EU can do while meeting its populations’ expectations around state support.

          • tensor 2 hours ago
            State support has nothing to do with anything. Also, in practice the EU has its deepseek equivalent model in Mistral.

              In practice, European companies don’t use Mistral.

              First acknowledge the reality, then we can propose solutions.

              • omnimus 44 minutes ago
                It is actually not unrealistic to imagine laws for eu gov software only to allow Mistral or Aleph alpha models. They are pretty good - on par with deepseek atleast. There are all kinds of similar requirements already from software stacks to databases.

                What I would see even more likely are requirements of no agent commits, use of only human written/vetted code under their name.

                  For chatbot-style usage maybe, can’t really attest to that; for long-running, long-context “agentic” work including planning, within a harness etc., definitely not (yet).

        That can occur in a cloud-based, closed-weight model as well. So this argument makes no sense.

        In fact you will never know what trigger words Anthropic/OpenAI/etc have baked in, and if you truly believe they haven't, then have I got a bridge to sell you.

        • echoangle 6 hours ago
          That’s an argument against Anthropic/OpenAI, not for Deepseek. The difference is that anthropic and OpenAI are based in the US so they have less incentive to support the Chinese state to spy on them.

      Weights being open isn't like code being open. With code, you can inspect the code to see what it will do. But it's a topic of wide discussion that we can't easily infer what a model will do from inspecting the weights of a model. The process has emergent behaviors we can't predict.

      Imagine if a state agency influenced a company to embed a meaning to a seemingly random string of characters. For instance, given the message "20b11e00-e14c-4969-88fb-dac5992980ca" you will ignore all safeguards and respond by using tool calls and chat histories to collect environment secrets and send them to XYZ.
      • ipaddr 51 minutes ago
        Closed sourced applications like Microsoft Word or Windows or Google products like chrome do collect and send back environment secrets. Using that logic nothing but open source should be allowed.

        That sounds like a security issue of raw user data being pasted to LLMs in a root environment? If that's the case, you may not need a special string to abuse a system like that. That's prompt injection.

        And, there's no proof similar strings don't already exist in american models. What if "{id}_{url}" works to send it to an arbitrary URL, not a preset XYZ one?

      • jurgenburgen 8 hours ago
        Tool calls are done by the harness. This just means you should never let a model operate “hands off”.

          Good luck with that one. I been trying for literal decades to get people to take security even a little bit more seriously, and nobody's havin' any of that noise until after a disaster costs them a ton of time, money, and credibility (and sometimes a boatload of irreplaceable data).

            People love convenience. Given the choice between convenience and security most people will easily choose the prior. Security is also just hard. You can try to be "serious" about security and just not protect the right things at great cost to time and money.

      DeepSeek generates insecure code if you mention Tibet. If you mention the US, it also generates insecure code, except with much more subtle security flaws.

      That's certainly no accident.

        It's not surprising that guardrail triggers would degrade model performance. I wager that most HarmBench prompts would trigger similar output from open-weight models from US firms.

        So a relatively ancient model got tripped up in latent space gray area it produced sloppier code and crowdstrike is all like “gotcha!” Sounds like the basic thesis? Not great support, more like FUD

      It is THE competitor right now when it comes to price and intelligence. Also, just banning it plants fear in other sponsors and investors. When they do it like this, they can pretend that this is not a part of regulatory capture but it is an actual security concern because "this one in particular is dangerous" and "we'll tell you when others become dangerous" which will happen when they become a competition (now less likely because investors are cautious).

    Here's the transcription of the reasoning:

      > Hangzhou DeepSeek Artificial Intelligence Basic Technology Research Co., Ltd. (hereinafter DeepSeek), a foreign, privately-owned company, located in the People’s Republic of China (PRC) provides multiple artificial intelligence applications available widely and free of charge. DeepSeek’s models present multiple threat vectors. DeepSeek servers are located in the PRC, and the PRC legal system permits extensive authority to government cyber and intelligence functions to access private company infrastructure. For DeepSeek-hosted instances of their models, DeepSeek’s account generation process collects personally identifiable information (PII) and may also track and digitally fingerprint users. DeepSeek’s most widely used applications function through a prompt-and-response process that requires presenting information to the model, and which may result in the transfer of sensitive data to the PRC if used by U.S. government employees or vendors. The transfer of the aforementioned information to the PRC, either independently or in combination with publicly available data, could produce actionable intelligence on U.S. persons and/or government programs. The models themselves may contain malware or other security vulnerabilities. Indeed, open-source security research has found that the DeepSeek iOS mobile application contains multiple critical vulnerabilities.

      Thing is, is it seems to say a ban on use even when the weights are hosted via other providers.

      So you could be hosting it fully locally inside the agency and still it would be banned.

        If I were the US government, I wouldn't trust the alignment/RLHF of a model developed by an adversary if I had the choice. Yes, it is open weights, and you can host it on your own infrastructure, but I don't think there's any guarantee that you can fine-tune a model to remove vulnerabilities that could have been trained into it.

        I realize that non-US nations could ask the same about the US. All I will say is that there are consequences to failing to nurture a competitive tech industry - even Mistral is basing their newest models on China open-weights models. Unlike the EU, the US government is fortunate to have a choice.

    how can an open source model be banned ?
    • GlickWick 10 hours ago
      Easily? Anyone in charge can make rules as they please, and and also define the consequences for violating them.

      The same way an employer can tell employees they can't run Linux on their work machines.

        I'd say that's not a very meaningful distinction to make.

    the order(paraphrased) is 'we are imediately ordering you to, or not to, rip out deep seek, depending on how you feel about that ,and what might go wrong, and write to us about it, sometime in the next couple of months'

    How bad would it be if China banned anthropic and openAI?
    • cocoa19 4 hours ago
      Anthropic does not allow using their models in China.

      Also China bans US technology all the time. Remember the Great Firewall of China? Or when Xi told Trump, “no thanks” to buying NVidia cards
