Woofun AI reports that White House officials have replaced Anthropic CEO Dario Amodei with co-founder Tom Brown and Public Policy Lead Sarah Heck to lead negotiations regarding the Claude Fable 5 model. This personnel change addresses communication difficulties and aims to resolve the security clearance impasse. The U.S. Department of Commerce issued a security alert on June 12 concerning 'jailbreak' vulnerabilities and foreign data access, prompting Anthropic to revoke access to Fable 5 and Mythos 5. Although President Trump stated in an Axios interview that Anthropic poses no national security threat following a G7 meeting, export controls remain in place. Officials express satisfaction with the progress under Brown's technical leadership, improving prospects for Fable 5's restart.
