Anthropic’s Fable 5 AI model has been hit with a U.S. export‑control directive after Amazon’s chief executive Andy Jassy alerted officials to exploitable prompts that could facilitate digital attacks, prompting a rapid response from Treasury officials and national‑security agencies on June 13 2026.
Discovery and Government Reaction
Amazon’s internal security engineers demonstrated that carefully crafted inputs could coax Fable 5 into revealing sensitive operational details, a flaw that contravenes the model’s built‑in safeguards. The Department of Commerce, citing national‑security concerns, ordered an immediate suspension of foreign‑national access to both Fable 5 and Anthropic’s Mythos 5, extending the ban to employees abroad.
White House and Treasury representatives, including Scott Bessent, convened emergency meetings with Anthropic to discuss remediation pathways. Officials presented the company with an ultimatum: rectify the vulnerabilities or withdraw the models from public deployment, underscoring the seriousness of the security breach.
