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!

Here's a copy of the letter that Commerce sent to Anthropic (note who it'a NOT addressed to...)

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of the diversion risks now presented by Claude Mythos 5 and Claude Fable 5, the controls in the June 12 letter are withdrawn.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

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.

I wonder if it's still good

>We’ve received notice that the Department of Commerce has lifted export controls on Claude Fable 5 and Mythos 5.

>We'll begin restoring access tomorrow, and will share an update soon.

>We’re grateful to our users for their patience, and to everyone who worked with us on redeploying the models.

From Anthropic on Twitter

They need Lehane or… since OpenAI got him, what is Fabiani up to these days?

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.

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.

So after this publicity they got, they will release a locked down version of the models, did I get that right?

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?

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.
