Anthropic says US has lifted export controls on Fable and Mythos AI models after security fears

The company Anthropic can now let customers use its new AI model, Fable, again. The government had stopped people from using it because they were worried it could be used for bad things like cyber-attacks.

The US government has now removed these controls. They worked with Anthropic to check the Fable 5 model and make sure it is safe. This helps America stay a leader in AI technology.

Last month, the US government told Anthropic to stop all foreign users from accessing Fable 5 and a similar model called Mythos 5. They were worried that these powerful AI tools could help other countries attack the US.

Now, Mythos 5 is allowed for some trusted US companies. These companies will use it to help protect against cyber-attacks.
