Tom Brown Chief Compute Officer Anthropic 548 Market Street San Francisco, CA 94104

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of the diversion risks now presented by Claude Mythos 5 and Claude Fable 5, the controls in the June 12 letter are withdrawn.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

Sincerely,

Howard W. Lutnick

"Taken Steps"

Looks like Anthropic paid the Danegeld. Now they'll never get rid of the Dane.

Jeff is now going to have to change his number. Can’t imagine all the calls or messages he must be getting now

For those who haven't been following this closely, who is the missing addressee?

Mildly surprising they lifted export restrictions for Mythos too. Isn’t that Fable minus the safety layer?

> note who it'a NOT addressed to

The CEO is also not the addressee of shipments of urinal cakes.

There is a deep, deep ignorance of export controls on HN, and I fully expect it will play out as another 500 comment thread of snark and incorrecting each other while blaming the government and not understanding a word of it.

FWIW an Empowered Official is not the person who cleans the espresso machine.

How many people are going to call Jeffrey Kessler? lol.
