    The damage is done. You cannot build a business critical function on top of American SOTA frontier model. Especially not with the current crew in charge.Now whether AI tech is in the same league as say Nuclear tech and therefore by any reasonable standard should be regulated is a different question.We hit the slippery slope on a random day in June 2026 and there is no putting the genie back in the bottle. Any exec or manager that puts load bearing weight on top of Anthropic/OpenAI/Google/AmericanCorp frontier model deserves the stress.

    Fable 5 apparently can't be used for coding? (This is from Anthropic's announcement.)> After a series of productive conversations with the US government, we're redeploying the model with a new set of classifiers to target and block more cybersecurity tasks. In the near term, some routine tasks like coding and debugging will fall back to Opus 4.8.Edit: the above was from their tweet announcement at https://x.com/AnthropicAI/status/2072163884430229756 ... the associated blog post at https://www.anthropic.com/news/redeploying-fable-5 suggests it was just poorly written and coding can still be done with Fable, just with overeager bouncing of "some routine coding and debugging tasks" to Opus.

    Here's a copy of the letter that Commerce sent to Anthropic (note who it'a NOT addressed to...)Source: https://x.com/AndrewCurran_/status/2072103733715194048?s=20-------June 30, 2026Tom Brown Chief Compute Officer Anthropic 548 Market Street San Francisco, CA 94104Dear Mr. Brown:Since the issuance of my previous letters, dated June 12, 2026 and June 26, 2026, Anthropic has taken steps in close coordination with the U.S. government to address the risks associated with Claude Mythos 5 and Claude Fable 5. Among other things, Anthropic has agreed to proactively detect and address security risks associated with the models; to work diligently with the U.S. government on protocols and standards and releases for Mythos, Fable, and future models; and to inform the U.S. government of any malicious activity.In light of these actions and commitments, as well as the Bureau of Industry and Security's evaluation of the diversion risks now presented by Claude Mythos 5 and Claude Fable 5, the controls in the June 12 letter are withdrawn. A license is no longer required for the export, reexport, or in-country transfer, including deemed export or deemed reexport, of the Mythos or Fable models.Commerce reserves the right to reevaluate the decisions made in this letter and the necessity of reimposing a license requirement, should circumstances change or should Anthropic fail to adhere to its commitments.If you have any questions about this letter, please contact me or the Under Secretary of Commerce for Industry and Security, Jeffrey Kessler, at (202) 255-1864.Sincerely,Howard W. Lutnick------

    The real problem in all this is lack of predictability. The White House is just making it up as it goes along. Investors, customers don’t know what the process is and can’t plan.In the end, we need actual laws that tell the market what kinds of models get paused / analyzed, how long that pause can be, etc.Otherwise there’s no standard and it will be easily abused and prevent investment in US AI companies.

    I bet you that nothing changed with how Fable 5 is run."Anthropic has agreed to proactively detect and address security risks associated with the models" LOL, this was already happening.This clown car administration just keeps making shit up and then backpedalling in a way that just leaves everything worse.

    Chinese models brought the building down.are export controls the right thing ? Probably not.but the american economy is over-exposed on "A.I" - the capital expenditure, while the Chinese are proving you don't need to spend tons of capital to get close to the frontier.the Chinese have better building capacity & cheaper energy. that means the market has to correct at some point.

    I struggle to imagine where anthropic is going with sub users...Fable 5 might not be accessible for sub in the future despite their "best effort".And 5.6-sol is as expensive as 5.5, so highly probable to be kept in sub.So what's the plan? Hoping people stay on ClaudeCode because Sonnet 5 while Codex offers 5.6-sol to subsription peasants?Seems risky

    I shudder to think what the definition of "malicious activity" is that they will be reporting to the government. Speech has been severely chilled the last couple of years.It's nice that the restriction is going to get lifted but I hope this doesn't make anyone complacent that their coding work is going to be scrutinized by the US government, with AI, when using these models.

    Fable was such a clear improvement. I can't wait to start using it again.Opus 4.8, you did a lot of good work for me, but in the name of all things holy... I will not miss your communication style. So long and thanks for the fish.
  • artisin
    Silly me for hoping they'd actually honor their original 14-day promise. Per their latest blog post, they've generously slashed the timeline to 7 days, but wait there's more! It's now limited to 50% of your weekly usage: > Fable 5 will be available starting tomorrow, Wednesday, July 1, to users globally... Fable 5 will be included for up to 50% of weekly usage limits through July 7, after which it will be available via usage credits. https://www.anthropic.com/news/redeploying-fable-5

    Can't do anything else with GLM 5.2 being widely available and advertised as "Mythos-like", and even Japan dropping a credible model. Actually it would only hurt to keep them in lockdown.
  • stavarotti
    I just finished reading Incorruptible and a central theme (Anthropic is a case study) is that trust is singularly the most important currency a business has. The past few weeks have done wonders for Anthropic’s marketing but just as much if not more damage to the trust factor. Businesses will continue to use Anthropic because it’s the default and accessible where it matters (AWS, Azure, GCP, Databricks, Snowflake, etc). But the trust factor has dropped. It’ll be interesting to see if they can turn the tide. Maybe Fable will be too awesome for people to care about the past few weeks?

    It's interesting that they will only have it on the surface through July 7, especially since GPT-5.6 will presumably come out soon as well.Of course, it's possible that Fable remains drastically better than 5.6, but to whatever extent Fable is the true frontier (if temporarily)... it makes me wonder if external commitments on compute put a hard deadline on how long they could run Fable on the subscriptions.

    Fable is still unavailable to me on both web and Claude Code. I'm in Indonesia on Max plan (new paid user, only 2 weeks in). Are there specific steps to re-enable it?
  • chungus_amongus
    For all the sound and fury we don’t even get a week of fable before it goes token based billing. At such time, I will be taking my business elsewhere.
  • indigodaddy
    Q: If/when Fable decides to nerd down to Opus on requests it deems dangerous, will we still pay the Fable API token rate?
  • nevi-me
    They should give us a month of access again, I feel like I didn't do enough with Fable before it got blocked.I only realised late that I had an algorithm problem that existing models were struggling with, and Fable had made progress with. It created a 14 phase plan, which I was able to execute with Opus after the restriction.

    Thank you to the folks that navigated the maze in the dark to make this happen.

    My only hope is that they don't overdo the guardrails. Claude's been one of the best coding models, and it'd be nice if it stayed that way for real and legitimate developer workflows.
  • mrandish
    Love how they waited until almost 5p west coast time on the last day of the fiscal quarter and clearly gave Ant no advance notice (or Ant would have had Fable release queued up on a button).
  • zxilly
    So we will get GPT 5.6 soon?
  • woggy
    Hopefully GPT 5.6 soon

    I wonder if it's still good

    Fable was (is) a major leap forward for my development tasks. The quality of the model compared to Opus 4.8 (when I last used it before the ban hammer) was night and day. Fable single-shotting complex and complete applications was a beautiful thing and I can't wait to get back to developing with it.All aboard the hype train!
  • satvikpendem
    So it seems like David Sacks was right that the US government only really got involved because the Amazon/ AWS CEO complained about latent security threats [0] and that the government was reluctant to actually issue the export control.[0] https://news.ycombinator.com/item?id=48529358

    Definitely took longer than I was expecting, then after two weeks I thought we'd never get it.
  • matheusmoreira
    Good to hear. I was going to cancel my subscription if I couldn't use Fable. No point in paying Anthropic to train models I can't use.

    Howard Lutnick is the 41st United States Secretary of Commerce. Howard Lutnick is known to have had ties to Jeffrey Epstein. From what we know and what has so far been released to the public, he is even documented to have visited his island.
  • drivebyhooting
    When is Google coming out with an equivalent Gemini model?
  • tinypak
    I see, so that explains why people are starting to talk about Claude Fable 5 and how I'm now going to have to buy $6,000 of compute for our startup
  • Sabinus
    The classic chaotic governance model and creation of an uncertain business environment by the Trump admin in the most important industry for the US economy.
  • tjohnell
    Who knows - this could be the last model we see from Anthropic. Or it just becomes the wild west and we figure it out as we go.
  • Sabinus
    Chaotic governance model and uncertain business environment by the Trump admin as usual.

    So how much did they have to donate to the MAGA PAC for this one?
  • jbritton
    I wonder if Anthropic servers can handle the load their going to get tomorrow. Unless it’s a staged rollout
  • natch
    They need Lehane or… since OpenAI got him, what is Fabiani up to these days?
  • woggy
    Basically not usable if it's only available via usage pricing.
  • poopyscoopy
    Debating if I should re-sub to the Max plan now (in case they grandfather people in some how) or if I should just wait and see what they announce.
  • HDBaseT
    The question is how lobotomized will it be now?
  • modriano
    So, uh, any chance us Claude subscription people are going to get the 11 days of Fable 5 access (at non API pricing) we were deprived of?
  • impodimium
    Huh did not expect them to lift restrictions this soon.

  • tamimio
    So after this publicity they got, they will release a locked down version of the models, did I get that right?
  • Havoc
    So much for way too dangerous end of the world

    Almost as though they were indefensible bullshit to begin with. I wonder who extorted whom and for how much.Like gee, that was fast. If this had any bearing on reality, one would imagine the vetting process would take actual time and that there would be a real, material difference between what we knew then and what we know now.The cartoon bullshit theater is exhausting.

    This is great news,I'm sure many teams couldn't do their best work because Claude Fable 5 was unavailable.I wonder what their hiring pages look like now, are they starting to remove job postings?
