Department of Commerce has lifted export controls on Claude Fable 5 and Mythos 5

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.

Fable 5 apparently can't be used for coding? (This is from Anthropic's announcement.) > After a series of productive conversations with the US government, we're redeploying the model with a new set of classifiers to target and block more cybersecurity tasks. In the near term, some routine tasks like coding and debugging will fall back to Opus 4.8. Edit: the above was from their tweet announcement at https://x.com/AnthropicAI/status/2072163884430229756 ... the associated blog post at https://www.anthropic.com/news/redeploying-fable-5 suggests it was just poorly written and coding can still be done with Fable, just with overeager bouncing of "some routine coding and debugging tasks" to Opus.

Here's a copy of the letter that Commerce sent to Anthropic (note who it'a NOT addressed to...) Source: https://x.com/AndrewCurran_/status/2072103733715194048?s=20 ------- June 30, 2026 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of the diversion risks now presented by Claude Mythos 5 and Claude Fable 5, the controls in the June 12 letter are withdrawn.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 ------

The real problem in all this is lack of predictability. The White House is just making it up as it goes along. Investors, customers don’t know what the process is and can’t plan. In the end, we need actual laws that tell the market what kinds of models get paused / analyzed, how long that pause can be, etc. Otherwise there’s no standard and it will be easily abused and prevent investment in US AI companies.

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.
