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.

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of the diversion risks now presented by Claude Mythos 5 and Claude Fable 5, the controls in the June 12 letter are withdrawn.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

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 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.

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.

>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

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?

I wonder if it's still good

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.

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

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.

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.

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

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!

ah, I see. so, Chinese models are getting banned soon.

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 much for way too dangerous end of the world

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?
