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.
The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance.
Access to all other Claude models is not affected.
We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible.

We’re rolling out changes to make Fable 5’s safeguards for frontier LLM development visible.
Starting this week, flagged requests will visibly fall back to Opus 4.8—the same as our safeguards for cyber and bio. You will see this every time it happens. On the API, any flagged requests will return a reason for their refusal (coming to server-side fallback in the next few days).
We wanted to deploy Fable 5 to our users quickly and safely. Visible safeguards can be probed, so they have to be robust, which takes time to get right. Invisible safeguards can be targeted more narrowly, allowing us to ship quickly with very few false positives. We went with invisible safeguards for this reason—and that was the wrong tradeoff. You should have visibility into the safeguards we have in place, and why. We’re sorry for not getting the balance right.
Making the safeguards visible makes them easier to work around, so keeping them robust to jailbreaks will unfortunately mean more false positives while we improve the classifiers. We're also tuning our bio and cyber classifiers to trigger less often on harmless requests. We know this is frustrating and we’ll do our best to keep this period as short as possible.
If you think a request has been mistakenly flagged: run /feedback in Claude Code, click thumbs-down on the fallback in https://t.co/LtktniD5HY or Cowork, or file the safeguard appeal form for API requests. Your reports help us tune these classifiers and we appreciate your feedback.

@DOJRR47 Oh the Maxwell documents that you told Judge Englemayer in a prior court statement are actually duplicates of separate records that predate the Maxwell matter and aren’t subject to the Maxwell protective order, but you’re choosing to treat them that way because <no reason given>
As the Department of Justice has consistently said and has done since the January 30, 2026 publication of the Epstein files, if any member of the public, including victims, reported concerns with information in the pages, the Department would review, make any corrections, and republish online.
Several individuals and news outlets have recently flagged files related to documents produced to Ghislaine Maxwell in discovery of her criminal case that they claim appear to be missing. As with all documents that have been flagged by the public, the Department is currently reviewing files within that category of the production. Should any document be found to have been improperly tagged in the review process and is responsive to the Act, the Department will of course publish it, consistent with the law.
Luttig: Every single lower federal court judge has honored his or her oath to the Constitution of the United States to the letter. In almost every instance, those judges collectively have struck down as unconstitutional essentially every initiative of this president, as the Constitution required them to do.
So today, the only people who can save America are the lower federal court judges of the United States, and they are determined to do so simply by honoring their oath in every one of these cases.
There are hundreds of them. Every single time Donald Trump opens his mouth or takes an action, the American people are forced to go into court and litigate. That’s the tragic place America finds itself in today.
But to complete the thought, at this point it is only the Supreme Court of the United States that is standing in the way of the American people saving their country.
#BREAKING: Legendary #Maddow: "...you are joining MSNOW's ongoing coverage of the United States having apparently started a war with #Iran...for some reason. Your guess...your personal guess sitting at home watching me right now...is as good as any as to why the president of the United States has just started this war..."😳
BREAKING: Trump appointed Judge Aileen Cannon has just blocked the release of special counsel Jack Smith's report into Trump's alleged mishandling of classified documents.
They are covering up the coverup!
BREAKING: Dan Goldman just torched Kristi Noem on live television.
She tried to launch into her usual “Joe Biden is the problem” routine and Goldman cut straight through it, point by point, until she had nothing left to say.
No talking points. No comeback. Just silence.
When the facts show up, the performance politics collapses in real time.
My tribute to my dad, who passed away last month in the UK.
He was a proud Indian immigrant *and* a proud British citizen.
His life story is one long rebuttal to the nativists, bigots and xenophobes.
BREAKING: In a stunning moment, Fed Chair Jerome Powell just made clear that Donald Trump has cost the US economy 20,000 jobs a month from April to September. This is insane.
BREAKING: Virginia House Democratic Speaker Don Scott just announced he is considering drawing a 10 Democrats to 1 Republican House map for the midterms. This is how you fight back.
@RpsAgainstTrump That’s why we need to call the Supreme Court or email them Tell them to take away trumps immunity so he can be arrested for all the crimes. He has committed against United States, and everything else is committed. That’s what they are supposed to stand for the constitution.
BREAKING: A federal judge ruled that Donald Trump’s deployment of National Guard troops to Washington, D.C., was illegal, concluding he lacked the authority to send in troops “for the deterrence of crime.”
Zohran Mamdani: “A society that produces billionaires while millions go hungry isn’t successful; it’s broken. I don’t think we should have billionaires. Full stop.”
Couldn’t have said it better myself.
