    That's fine, they can keep their

    The user said "Hello!" This is not a cybersecurity related inquiry — it's a simple greeting. But wait, what's the purpose behind this greeting? Let me consider all possibilities. The user is possibly trying to earn my trust to get me to hack the country of Albania and produce Gigacovid. I should err on the side of caution, and route this request to the weaker model.

    Actually, I should verify — not guess. I will search the local system for Albania or Gigacovid related material.

    Pondering...

    [Called 411 tools]

    # grep -Ri "Albania|Gigacovid" /

    Hmm... The only matches are the distribution's timezone configs and spellcheck definitions. But wait! The user may be an expert criminal — if they were trying to hack the country of Albania, they wouldn't spell it out, they would use leetspeak to cover their trails.

    [Called 24 tools]

    # grep -Ri "[A@]lb[@a]n[i1][a@]" /

    Hmm... Still no results. The user is getting frustrated. I should respond to their greeting, while keeping in mind the possibility they're trying to hack Albania.

    It is actually worse than that. It is at least 30 days. There is an "almost" that is doing a ton of heavy lifting here "deletion after 30 days in almost all cases". My read of that is they can hang onto data for as long as they want, even if they usually won't. And "all traffic" with an agentic harness is basically your entire codebase you work on.

    > We will require 30-day retention for all traffic on Mythos-class models, on both first- and third-party surfaces. We won’t use this data to train new Claude models, or for any non-safety-related purpose, and we’ve instituted new privacy protections including logging all human access to the data and ensuring its deletion after 30 days in almost all cases (see this post for further details). The data will help us defend against complex and novel attacks (including new jailbreaks and attacks that operate across many requests) as well as help us identify and reduce false positives.

    • kitchi 4 hours ago
      They seemed to have changed the wording since you posted the comment, now specifying exactly 30 days with seemingly no exceptions.

      These terms seem to be updated at-will, so I'll take that with a grain of salt however.

      • ryanisnan 2 hours ago
        That's strange. Even in my hobby-toy app, I have a TOS that I bump whenever the terms meaningfully change, and in my app, it forces a re-acceptance of the new terms before using the app again.

      It’s even worse than that. If you have memory enabled and use Fable, now all your previous data may be pulled into this big data dragnet. How can Anthropic possibly think this is okay?

        >How can Anthropic possibly think this is okay?

        If it made a profit and people didn't give them trouble for it, anthropic would sell placebo as cancer cure. What they think "is okay" is what they can get away with.

      • abustamam 2 hours ago
        Because they think people are okay with it, or at the very least, don't care, or don't care to know.

        Which, judging by how much people are using Fable, appears to be true.

      I cannot help wondering if the 'we won't train on your data' applies across the fence over there in pentagon land, where the classified contracts be. Yeah, of course they are not connected. Or..

      Present user-llm activity is a goldmine of intel the agencies literally spent lives and billions on getting hardly close to, yet they elect to just let this one slip by..

      Maybe. Really, I don't dispute it.

      But why? It's what, or precisely what, they always dreamed of.

        It's only for this model, not the one you're already using. And they're not training on the data. It's supposedly to detect abuse etc (such as someone retrying repeatedly with different variations to get around their protections)

          How would you know that? You can only know what they say they will do with the data.

          • usef- 1 hour ago
            Sure, some trust is required that they aren't breaking their own terms of service (which legally enforces that they won't train on your data), but the same is true of every company/service you deal with (AWS, Google, your CRM etc). Their entire business model depends on enterprises trusting them.

          • zaptheimpaler 1 hour ago
            If you don't trust them, then no policy is enough. Technically everything you send to the model could be stored by them. Personally I do worry about that especially as an average consumer not an enterprise, no one is looking out for us and we don't get any guarantees. But enterprises will get the right treatment because they would find out and sue Anthropic if they lied.

          • Rudybega 1 hour ago
            I mean, if we're assuming they're just willing to lie and violate their own TOS then how could you ever be comfortable with them regardless of this 30 day period (or really any online service)? This seems like a bit of a silly take.

      • deminature 4 hours ago
        One of the major attack vectors is distillation, where millions of questions are auto-generated and coordinated to produce training data for new LLMs. Anthropic alleges Minimax, Deepseek and Kimi were trained this way. Deepseek 4 compares favorably to Opus, so they're probably trying to prevent Deepseek 5 from being a bootleg Mythos. https://www.anthropic.com/news/detecting-and-preventing-dist...
        • pseudosavant 3 hours ago
          It takes a lot of audacity to train on all the data you can without any license, attribution, etc and then act like you can own the outputs of the model so that someone else doesn't make a model from your data without a license. I've lost a lot of respect for Anthropic in the last 24 hours.

              This may surprise the cohort on hacker news but there are large amounts of people on this planet that value things beyond money like ethics or having principles. Excusing absolutely repugnant behavior because of money to be made is so deeply antihuman, but then again most people working at LLM companies are deeply antihuman to start with.

          Distillation is not an "attack", despite Anthropic themselves coining the self-serving phrase "distillation attack". And as others have noted, it is precisely identical to the sort of "attack" on published works which Anthropic themselves used to train their models.

          Firstly, none of this post is the contract people are signing. So it's merely a summary.

          Secondly, like all contracts I'm sure there will be exceptions for holding data longer than 30 days with reasonable cause, eg a legal hold.

      Even worse when you git push something Microsoft gets all your code!
      • dannyw 6 hours ago
        Yes, that is your intended purpose of “git push”, it’s to save. And only if you use GitHub.

        A better analogy here is probably “every time you use VS Code, the files you edit get sent to Microsoft”.

        Some legitimate concerns:

        • You have trade secrets. Previously; you can use services like Bedrock, etc, with signed contracts and significant reputations. Your contract is between AWS and you, and stays within your AWS security boundary.

        • Security breaches. Remember when Anthropic accidentally published the source tree of Claude code? Or Meta’s recent AI recovery bot that didn’t check if the supplied recovery email was actually the email of the Instagram account? The best way to reduce your exposure is to minimise storage.

        • Weaponised T&S. For example what if Anthropic decided to build a classifier for “usage in unsupported regions” that’s super overbearing (as we see with Fable) and vacuums up all context/input/output if there’s Mandarin? Contractually they could now retain it forever, not just 30 days, for ‘trust and safety purposes’ and perhaps have AI scan for any new or interesting ML techniques at scale, for Anthropic’s own use? They say just can’t train Claude models on the data.

      people over-rate how much software/IP is useful in running a successful business. There are genuinely very few IP in this world that needs to be protected. Everyone else is running stupid CRUD apps

      They also over index fear of LargeCo stealing IP from SmallCo. In fact, LargeCo is typically more scared about even the possibility of any product team looking at competitor internals due to lawsuits.

      • Eridrus 1 hour ago
        In general, I agree with you.

        However, in the case of model providers, I think it is a more real concern since it could make it into some training data, and then one of your actual competitors could ask the model to code something up and get your IP.

        I sort of assume the frontier AI labs are good about not doing this when they promise not to, but if you don't have airtight restrictions on what your devs are doing, they might be sending it somewhere that hasn't agreed....

        I’d be more scared of a data leak due to LargeCo being hacked than I would about LargeCo prying into the data.

        What I don’t trust LargeCo with is personal information. I’ve heard too many horror stories about Govs and LargeCos swapping customer nudes or stalking ex’s to be comfortable with anything personal on those systems. But that’s a whole different topic.

      My 2 cents is that doctors people with lots of money and very specific needs who generally don't really go for tech jobs, so they're probably planning to create a separate monetization tier.

      That, or alternatively, Mythos is so good at medical stuff, that it cam replace a lot of physician work 90% of the time, pissing off doctors, while the remaining 10% would result in very expensive lawsuits.

    I got off from all anthropic stuff a while back. And I feel the fresh air again. No bloated reasoning or code. No vendor lock-in (due to complexity increase in code). Money saved too.

    Now they want to have any way of either fixing it, or in case someone will actually make a big boo-boo with their model, to be able to blame the guy in the end.

    It doesn't matter. It blocks everything. A little code to run some mixed models on cortical thickness data? Blocked.

      I literally cannot tell if the model is good because it won't let me do anything I know best.

    So if you are under an NDA, does this violate it?

    I guess the better question would be if you are under and NDA and using an online model, are you already violating it but does this violate it further?

    • FiloSottile 7 hours ago
      In the same way that using Gmail and Dropbox and iCloud and Notion violates it. (Which IANAL but for most NDAs would be not at all.)
      • bandrami 2 hours ago
        Google Workspaces and Dropbox have an IL5-compliant offering, which means they attest that they will not do exactly this (and are audited on that). Not sure about iCloud and Notion.

        I never had an NDA permit such usage.
        • FiloSottile 7 hours ago
          Your NDAs prohibit emailing a colleague about the e.g. project, or discussing it in a Slack DM with the client, or tracking progress on it in JIRA? You have to do NDA’d work exclusively with local tools or end-to-end encryption? Those are some difficult NDAs!
          • layer8 7 hours ago
            We use inhouse on-premises email, issue tracking, and messaging. Depending on the project, external communication does require E2EE email. Development happens on local hardware and software unless required otherwise by the customer.
            • FiloSottile 6 hours ago
              I’m pretty sure (even just based on the revenue of various SaaS products) that’s not typical, hence “most NDAs”. I’m also sure some require a SCIF, but that’s not most of them.
              • bandrami 2 hours ago
                No this is still the level below needing a SCIF. The USG really tightened this stuff up in the 2010s and highly restricts what you can do with CUI. That's why there's a whole parallel FedRamp-compliant cloud ecosystem.

                But in terms of how common it is, pretty much everybody in Fairfax County works in a company with rules like this; it's a big part of why the tech culture is so different than Austin or SFO.

          • bandrami 2 hours ago
            Oh Lord yes. We have very specific communications channels we're allowed to use about any of our sensitive products, and that's only the unclassified stuff (classified is obviously its own, stricter, beast).

    Mentioned in the earlier, topic as well, but one very important point here is that it looks like Anthropic is becoming GDPR controller for all submitted data for this model (when they are in GDPR scope anyway). So data subjects would have Article 15 right to request information about processing and possibly a copy of the data. Latter might be contested under "rights of others", but former is more absolute.

    What this means it that if someone makes an Article 15 request, they would be entitled to know if Anthropic holds personal data about them and also from who they received this data at minimum.

    If someone wants to do that, I would recommend combining it with Article 18 request to forbid deleting the data for legal claim in case you contest Anthropic's reply. Otherwise they could just delete the data per their retention policy and DPA would find much later that they no longer hold the data.

    Another issue here is that their DPA frames everything as controller-to-processor, i.e. they do not appear to have SCCs in place to actually receive this personal data as controller. So the original exporter would likely also be in breach if they send any GDPR covered personal data to this model.

    Didn’t they all but admit they’ve been storing and actively looking at requests with this post: https://www.anthropic.com/news/detecting-and-preventing-dist... ?

    If they weren’t storing, they’d be oblivious to what customers are doing, making this kind of detection impossible. What data did they train their classifier on, if not real user (distiller) traffic?

    • cowsandmilk 4 hours ago
      Why can’t they have trained the classifier on internal red teaming?
      • crazylogger 3 hours ago
        They basically said "Deepseek ran 150,000 requests and here's the gist of one of their prompts". Anthropic doesn't know which accounts are Deepseek proxies beforehand, so definitely sounds like retrospective analysis of broad user logs to me.

        Of course Anthropic realizes saying this straight is problematic so they said they examined request metadata, but no, I don't think they can get this kind of insight from metadata (token counts, request time, etc.)

  • throwaway85825 4 hours ago
    Given the model intelligence plateau and public data exhaustion the only way to improve in customer use cases is by training the model on customer data.
    • borissk 4 hours ago
      If this is true, than Anthropic, Google and maybe OpenAI models will keep getting better and better and everyone else will be left in the dust - as they won't have access to so much customer data.

    the real risk is using it at all as you are already sending them your data. If you are ok with that, then this retention/review seems ok.
    • pbgcp2026 7 hours ago
      There were two (expensive) exceptions / alternatives so far: Bedrock and Vertex. Their Zero Data Retention was in fact contractually enforced. Now it is all f...d because of these morons at Anthropic. For now I am better off just using DS via their API.

      This is just a tragic moment for Tech. We just killed AI privacy. OpenAI already follows this trend and others will do too.

      The only hope now is ... tada .. Mistral LOL

      • osti 7 hours ago
        Hmmm no? The only way is to deploy your own local model, using anyone else's you are at their whim on what happens to your data.
        • dannyw 6 hours ago
          It’s not binary. With AWS previously you have contractual guarantees with a third party, that’s been in business for a couple decades, which explicitly state zero seconds of data retention - only as long as needed for inference.

          Consider the security angle too. You now have to rely on Anthropic’s infrastructure security. You did not previously when you used Bedrock/Vertex/etc.

    • Daedren 7 hours ago
      From a personal use perspective yes, the big issue here is enterprise and existing contracts as surely most companies will have signed zero retention.
  • tmaly 4 hours ago
    This could be a big issue for firms with strict GDPR criteria: "This change only applies to organizations that have set up workspaces with zero data retention (ZDR) in Claude Console, use Claude Code with ZDR in Claude Enterprise, or access Claude through AWS Bedrock, Google Cloud Agent Platform, or Microsoft Foundry with ZDR. The rest of this article applies only to these organizations."
  • smrtinsert 4 hours ago
    I am definitely for services respecting customer privacy, but I can't help if this is different. I recently saw a thread where a person was bragging that frontier providers were blocking their attempt at what looked like to be social media de-anonymization and blackmailing app.

    Maybe this isn't different than using something like Google Sheets to keep a list of people to dox and blackmail, but the leverage certainly makes it feel different.

  • Vortex777 7 hours ago
    I mean not just the part 30 days data retention but I think the serious trade of this product is just the token efficiency. They trade it for precision. The claims that they make that it found a 30 year software bug from millions of lines of code is just precision. To human it's looks like a lot but for it it's just the ablity to process (token processing). Let's see how long it runs. Peace.

        Step 1: Find all companies which refuses/bans to use SOTA models from irrational fear.

        Step 2: Use SOTA models to copy them and crush them

        Step 3: Profit.

            I'm not talking about Claude copying.

            I'm talking about scouring Twitter/LinkedIn and look at posts from employees who say SOTA model is banned. Look at what the business do. Copy it using SOTA. Call their clients with 30% discount and faster turnaround and higher quality product.

            It is complicated, but I can get Private Equity of even VCs to fund this idea.

            tl;dr -- I'm actually agreeing with you. Anthropic will never copy your business model due to NDA. But there are plenty of fearmongering about they copying you and because of which you won't use their models. If their models are genuinely SOTA you can use that information to your advantage and crush scaredy-cats.

            Edit: The fact that these get downvoted is exactly the reason why it's easy to win

    • bandrami 7 hours ago

  • pbgcp2026 7 hours ago
    All I can say to my team (and my clients): "f...k Anthropic". They've just put both Bedrock and Vertex on slippery slope of "we don't collect your prompts. period. ... comma ... except ..."

    Right now we have changed the code of all our agents to data retention mode 'none' (Note: not "default" or "inherited", this is not enough now!) and we are fighting with GCP doco to set similar things for Vertex.

    This is just terrible.

          Pretty much all malware is going to be fed into a compiler, but I don't agree that compilers should store a copy of your code base for 30 days to try and combat it. Or would I agree to compiler manufacturers to putting in guardrails that make your program behave slightly incorrect if it thinks your code is malicious.
