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?
I'm absolutely fascinated.

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of the diversion risks now presented by Claude Mythos 5 and Claude Fable 5, the controls in the June 12 letter are withdrawn.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

It's nice that the restriction is going to get lifted but I hope this doesn't make anyone complacent that their coding work is going to be scrutinized by the US government, with AI, when using these models.
On a lark, I asked Claude to compare AI to the wild west a while ago. It raised three points of similarity:
- Land-grab economics
- Lack of regulation
- Changing social and professional attitudes.
Whatever it is, it's a wild ride regardless.
In past Empires kings bet their entire nations future on the words of soothsayers , people who said they could predict the future. It seems like Machine Learning engineers are the magicians of Empire of the modern age.
Depends on how economically useful AI turns out to be. It will be useful, but it needs to be VERY useful for the current valuations.
>In past Empires kings bet their entire nations future on the words of soothsayers
I think AI's rise is much closer to the story of factory machines and computers than to soothsayers and emperors.
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.
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.
I think Europe and Canada are just happy not to be frozen out of AI access completely at this point.

Of course Anthropic is still relevant, but people have realized they’re not special, and between this and the ID verification thing, they’ve given up a ton of their relevance vs a month ago.
All aboard the hype train!
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.
ah, I see. so, Chinese models are getting banned soon.
"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.

I assume they did something to the model itself.
Either way, I do hope they lift those draconian bans. Using the model was a terrible experience because of the constant downgrades. I didn't manage to harden my own projects before Fable got banned.
Yes you use the right tool for the job.
But if the job requires the best intelligence you can get with an LLM, then you use that.
Taking as an assumption that the quality of your product is a function of the quality of the inference you are using: if you use an inferior model because "what if it gets export controlled again" and your competitors don't, then your competitors are likely to win.
If you don't need frontier models for you job then this is all moot, but the thread started with
> You cannot build a business critical function on top of American SOTA frontier model
Which is silly. HN likes to roleplay bringing everythgin "business critical" in house because sometimes vendors mess up. Self host, don't use the cloud, run open models locally, built redundant supply chains in case of another covid, etc etc. Sometimes the risk is real, but most of the time the risk is rare and the cost of an interruption event is less than the cost of bringing everything in house or using lower quality vendors "just in case"
Yes 1000%, please, all my European competition please don't use mythos whatever you do it's total USA trash and the Chinese models work better anyway.
