Dear 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of the diversion risks now presented by Claude Mythos 5 and Claude Fable 5, the controls in the June 12 letter are withdrawn.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.

How likely is it the resolution was just a direct flow of data on what each Claude user is specifically using Claude for, probably sent off to some other (gov-owned) AI datacenter for analysis?
He's the one who led the choice to refuse working with the gov for surveillance or defense, and it led to that block right after.
I have no proof but I assume he believes at least some of what he's preaching (which doesn't mean he won't fold, at the end of the day it's an american company anyway).
Brown is probably more of a diplomat, "Sure, but not now" goes a lot further than "No, never", though it has the issue of kicking the can down the road.
> He's the one who led the choice to refuse working with the gov for surveillance or defense
This is false and just Anthropic being good at PR. He's happy to let it be used for airstrikes on Iran for example, just wants to keep a human in the loop. So the AI will say 'I am extremely sure this building (a girl school) is a military base' and the human will say 'I am being asked to carry out more airstrikes and who am I to question AI' and will bomb a school with Amodei then washing his hands.
You can find a source for it being used here [1] though parent is misrepresenting it either on purpose or by lacking understanding, I stand to my point above, the timeline is
1. the US used it, in venezuela then to prepare Iran
2. it became public through journals reporting it, but they didn't really hide from it afterwards and told explicitely what and who they used, naming anthropic
3. Diego (the CEO) answered by saying this violate terms and the US is not allowed and should stop that immediately, publicly
4. They have a talk, and while concessions are made it blocks not about war with ennemies but about surveillance at home, which Diego refuses to let go
5. Trump reacted by calling Anthropic a "Radical Left AI company run by people who have no idea what the real World is all about"
6. Peter Hegseth annonce they will stop using it but asked for a stop gap deal "Anthropic will continue to provide the Department of War its services for a period of no more than six months to allow for a seamless transition."
7. Open AI annonce a deal with the governement four and a half HOURS later, with totally cool safeguards "We think our agreement has more guardrails than any previous agreement for classified AI deployments, including Anthropic's", journals note that "OpenAI's new Pentagon deal doesn't explicitly prohibit collecting Americans' publicly available information - a sticking point that rival Anthropic says is crucial for ensuring domestic mass surveillance doesn't take place"
8. In totally unrelated news, Anthropic new models get banned for exports in a move the US has never done before, no other company has their models banned
And now
9. Anthropic change the person talking with the gov to Brown
10. After a bit anthropic models start being unbanned
Maybe he just lacks social skills, but I remember watching videos of him talking about mass job loss with what looked like glee on his face. All his actions and communications do not give me a sense that his "principles" are good or even what he claims them to be
Could you please stop posting unsubstantive comments and flamebait? You've unfortunately been doing it repeatedly, and we already asked you a couple days ago.
Your comment, genius. Makes me miss n-gate dotcom, which hasn't been updated since 2021. This comment would make a great entry. If you aren't familiar with it, you really want to be.
One of the contributing factors that led to this control in the first place was that the commerce department couldn't get Dario on a call immediately:
"Then White House started reaching out to Anthropic to speak with Dario Amodei, who was at a wellness retreat.... When Amodei was finally available past 1pm, he had three tense phone calls with a combo of ppl including Cairncross, Bessent, Lutnick, Kessler, Will Scharf, Richard Walters, and Walker Barrett."
Anthropic has disputed that Dario was at a wellness retreat but both sides seem agree that it seemed to be a problem (and it is very apparent that Dario's response made things worse).
It's shocking to me that Anthropic seems to be run with the same managerial chaos as depicted in early seasons of Entourage.
Dario may be a genius, but when it comes to running a big business — which involves dealing with governments and regulators — it's like he just fell off a turnip truck.
