The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees.
The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance.
Access to all other Claude models is not affected.
We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible.

OpenAI has released the language in their contract with the DoW, and it's exactly as Anthropic was claiming: "legalese that would allow those safeguards to be disregarded at will".
Note: the first paragraph doesn't say "no autonomous weapons"! It says "AI can't control autonomous weapons as long as existing law (that doesn't exist) or the DoD says so."
Similarly, the mass surveillance use cases will "comply with existing law", but many forms of data collection that we'd consider "mass surveillance" are things that the NSA has consistently argued are legal under current law.
Introducing the next generation: Claude Opus 4 and Claude Sonnet 4.
Claude Opus 4 is our most powerful model yet, and the world’s best coding model.
Claude Sonnet 4 is a significant upgrade from its predecessor, delivering superior coding and reasoning.
If you are not planning for the price of intelligence to go to zero, the next 3-5 years are going to incredibly disruptive to your business / life.
