Anthropic CEO Dario Amodei has reportedly stepped back from discussions with the White House on the Fable 5 ban, and talks have since improved. According to a report from Wired, discussions are now led by Anthropic co-founder Tom Brown and head of public policy Sarah Heck. The White House had become more comfortable engaging with Anthropic after Brown replaced Amodei, with one source saying, “Tom Brown is not being a weirdo like Dario and can actually engage.” Earlier this month, the US government directed Anthropic to block foreigners from accessing its Mythos 5 and Fable 5 models, and Anthropic pulled access from all users. US President Donald Trump had praised Amodei for responding quickly to the directive. The dispute centers on Anthropic’s Claude Fable 5 and Claude Mythos 5 models, which are built on the same core technology as Claude Mythos Preview, previously considered too dangerous for public release. Fable 5 was presented with safeguards to reduce cybersecurity risks, but concerns emerged that those protections could be bypassed. The White House has yet to lift the ban, and both sides have held multiple calls, including technical discussions, to identify evidence needed to address jailbreak concerns.
