    This whole thing is comedy.

    Anthropic pretending Mythos 5 is so capable it's going to destroy everything, but will release it anyway with "safeguards" (when does this ever work?).

    US Gov't using this fake hype as an excuse to handicap Anthropic simply because they have a vendetta.

    • anon373839 2 minutes ago

      I wonder if there even is a real vendetta. How many people in the administration / friendly with the administration would benefit financially from the IPO? Maneuvers like this still pump more air into the hype balloon. I suspect that Anthropic and its backers did not enjoy the many "meh" reviews that Fable has received for its modest bump in output quality.

      Nothing is funny about LLMs being restricted like air travel.

        Yeah it is.

        Unless you work at Anthropic, OpenAI, Google, or Meta.

        Your stocks/RSU are at risk of losing significant value.

        • koolala 9 minutes ago

          No it isn't. LLM's are a form of access to information like Public Libraries or the Internet.

          • sethops1 5 minutes ago

            The content produced by LLMs is literally stolen from the internet.

      That or an excuse to put controls on all AI and massage the message for why we have to ban Deepseek.

    • bottlepalm 27 minutes ago

      I find it funny that AI keeps getting bigger, and the mental gymnastics needed to trivalize the progress get bigger as well - ie the government shutdown an AI model twisted into now even the government is being tricked.

      Everyone is tricked except me. Only I know AI isn't as smart as everyone thinks it is.

      • reassess_blind 2 minutes ago

        Not as smart as everyone thinks it is, maybe, but a model like Fable 5 without safeguards against offensive cyber attacks would be a nightmare. There are millions of improperly secured web applications that, in the wrong hands, would be easily exploited by these models.

        “Too dangerous to release” has been exploited for marketing.

        A sizeable plurality of the informed public know as much.

        Regulatory capture is a thing.

        Or you could use it, and see the massive disconnect between hype and reality yourself. It’s not hard.

        The market is built on hype, so of course it’s going to get hyped everywhere.

      • ianm218 19 minutes ago

        I feel like it is strange seeing some really smart people go full conspiracy theory tin foil hat. Half these threads think that Anthropic is playing some 5D chess game to purposefully get nationalized.

  • spangry 19 minutes ago

    "The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any *foreign national*, whether inside or outside the United States, including *foreign national* Anthropic employees."

    This press release is odd - it says that the export control was imposed to stop foreign nationals from using Fable / Mythos, and then goes on to talk about supposed concerns about jailbreaking the model.

    But is that really the concern of the US Administration? This looks more to me like they are viewing frontier models as a strategic asset which they want to keep for US-exclusive use. I can see the logic - if frontier models generally accelerate a society's technological development, then a country looking to retain or increase its strategic edge over other countries would try and keep this sort of multiplier for themselves.

    I'm guessing Anthropic shut of access for everyone because currently they have no reliable way to know whether a user is or is not a US citizen. In the near future we might be in a situation where you need to prove your US citizenship before Anthropic / Open AI will allow you to use their current frontier model.

    • koolala 11 minutes ago

      Your defending the US Administration wanting ID verification built into our devices like going through airport security because you think they think it is 'pro-US'?

  • overgard 15 minutes ago

    Well, in the brief window that I got to test Fable 5, my brief review is: somehow an (already specced!) minor feature in my 150k loc codebase ended up costing.. $153! For like, an hour or two worth of work and maybe 8 or 9 requests overall. I'd say it was not remotely worth it.

    • zzleeper 7 minutes ago

      I asked it to tweak the fonts/colors of a very very simple static page and it blew through $35 (which is a lot for me lol; it's 10 days of my monthly codex plan).

      If I used a racecar to go 25mph in a residential neighborhood, I’d make a similar conclusion.

  • winterbourne 6 minutes ago

    Huge PR win for Anthropic if they can restore access within a week or so.

    Will be interesting to see OpenAI's next move.

    • koolala a minute ago

      Unless there is major administration change, how do things not get worse and worse from here? LLM's will only get more intelligent and be seen more of a national security risk. This brings the surveillance state deeper into every web connected device.

    Probably Iran used Fable to negotiate an awesome deal for them. And made the president angry. xD

    > The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance.

    Not great as it does break workflows for some.

    > As we have stated publicly, we believe the government should have the ability to block unsafe deployments, as part of a statutory process that is transparent, fair, clear, and grounded in technical facts. This action does not adhere to those principles.

    Did Anthropic, unlike Open AI, forget to offer free equity to the government?

    “Thats a pretty nice IPO you got there… it would be a shame if something happened to it.”

      There is no harm to suspend something twice. Especially is the something doesn't exist :)

    Good. 4.8 is good enough.

      I love 4.8 but it's insufficient for the tasks I want to run.

      Guess I'll find something else to work on.

  • tinyhouse 28 minutes ago

    At least on Claude Code it's completely useless. It tells me to run all the commands myself cause it's blocked ("Classifier's blocking me again" lol). Just tried now and saw the msg: "There's an issue with the selected model (claude-fable-5[1m]). It may not exist or you may not have access to it. Run /model to pick a different model."

    I really have no clue how Anthropic released this thing without doing any real testing. I did use it on claude.ai with no issues; talking just for code.

  • Imustaskforhelp 10 minutes ago

    Yesterday, was thinking just randomly about Fable 5 and I was thinking that what if Anthropic just removed access to Fable 5 from the subscription to something only API-based and charge so much more excessively from it.

    I was this close to predicting the (complete) suspension in some sense but for different reasons (compliance)

    but this is a bit of shit-show at this point and I am unsure how involved Anthropic is.

    Maybe Anthropic gave us access to Fable 5 for some point so that we can all discuss it and see how Anthropic is relevant as compared to gpt 5.5 (not that I like ClosedAI more but fact is that I have heard decent things about it)

    So I am not sure if this suspension can lead to an idea like me. Anthropic showed us a really competent model and then removed it and now you might have to form a custom deal with Anthropic or similar maybe similar to mythos if you wish to access the models and they can rake in extra dollars from top clients.

    but they were already doing that with mythos, then what was the point of Fable. PR support that Anthropic hasn't fallen off?

    Or maybe I am just overthinking and Anthropic is genuinely hurt by this decision given that they did release the model but US govt said no and US govt and Anthropic has some beef with each other.

    There are so many factors for this news and the narrative/implications of that, that it is hard to understand what really happened unless some more news comes (IMO)

    They'll make a book with mythos's code and sell it like Phil Zimmerman did with PGP?

      Now the government uses AI as a way to check your ID online like age restriction but for citizenship. It's not about safety its about control.

    More free PR for anthropic. “Our models are so powerful the govt shut them down”. Insert image of Dario looking like his dog just died.

    So tired of the nonsense.

      Is there any evidence, anything whatsoever, that would convince you the models actually are so powerful?

      • kaliqt an hour ago

        Maybe. Maybe not.

        His point is that Anthropic is likely doing this on purpose for their own IPO and to counter the other IPOs.

        • SpicyLemonZest 44 minutes ago

          I don't see how one could possibly come to that conclusion, except by rejecting out of hand the idea that there could be a true threat requiring genuine caution.

            > rejecting out of hand the idea that there could be a true threat requiring genuine caution.

            What true threat could possibly exist where the models are perfectly fine to use, just only by American citizens?

        • Tossrock 42 minutes ago

          Anthropic is... making the US government shut down their flagship model on purpose? The conspiratorial thinking on HN is approaching UFO subreddit levels.

          • thewebguyd 17 minutes ago

            It's so difficult to have rational AI discussion here anymore. Half (or more?) of the developer community seems to have some form of AI hysteria that causes them to throw all logic out the window in service of the magical machine god.

      • weird-eye-issue an hour ago

        They didn't say they are. They said it is PR which is a type of marketing which has to do with perception not reality.

      • jrflowers 25 minutes ago

        Are you asking somebody what evidence they have that their observations are wrong? Like “I see you have an opinion there. What facts are you aware of that disprove it?”
